Planets and Space Travel – Science for Kids

planets-and-space-travel-for-kids

We’ve learned about Gravity, our planet, Earth, and on our field trip to the Bellevue College planetarium, we learned about stars and constellations that we observe from Earth. This week we learned about the planets in our solar system and about space travel.

Crafts – Building Scientific Models

Orbital Models: We wanted the kids to create a model where they could see how the earth orbits the sun, and the moon independently orbits the earth. We had three ideas for how to do this, and ended up putting out the supplies for all three options on the table, and some kids / parents got creative and came up with even more ways to model this.

You could:

  1. print this template, color in the earth and sun, cut it apart, assemble it with brads
  2. Use a large paper plate for the sun, a small paper plate for the earth, and the bottom of a Dixie cup or a small circle of paper to represent the moon. Decorate them, then cut two long strips of cardstock. Connect the earth to the sun, the sun to the moon.
  3. Use a CD for the sun, a juice can lid for the moon, and a bottle cap for the moon.

Once you’ve assembled the model, kids can explore how the earth orbits the sun, and the moon orbits the earth.

(Note: I don’t know the original source of this idea – it appears all over Pinterest – just search for “sun moon earth model” to see several samples.)

Orbital Mechanics Wand

Supplies needed:

  • big Styrofoam or soft rubber ball, to represent a planet
  • small Styrofoam ball, rubber ball, or Christmas ornament, to represent a moon
  • string to represent the pull of gravity
  • dowel, skewer or pencil
  • tape and scissors.
  1. Poke the skewer (or pencil) into a large ball.
  2. Tie a string to the smaller ball.
  3. Then tie the string firmly to the skewer – slide it up close to the planet. Tape in place so it can’t rotate.

You have created a model of a simple planetary system like Earth’s – with one planet and one satellite moon. Try twirling the small ‘Moon’ around the larger Planet on your wand. Observe how, as it draws closer, the moon travels faster around the planet. This is one of the basic principles of Gravity and Orbital Mechanics that every astronaut knows and is an example of Centripetal Force.

Science Inspired Art Projects

Martian surface. Kids could trace around a lid from a large tub to make a circle on cardstock, then paint it with Mars goo – paint mixed with flour. They could sculpt mountains and craters in the goo. We placed a photo of Mars on the table as inspiration.

IMG_20160206_105107677

Phases of the Moon: Kids could also use textured paint (paint mixed with flour) to paint the phases of the moon on cardstock (include a poster at the station to illustrate the phases). They can use the end of a straw to make “craters.”

img_20170211_121453566_hdr img_20170211_121445427

I also really like the idea from Mrs. Myer’s kindergarten, to have the kids work collaboratively on BIG paintings of the phases of the moon.

Jet Packs: Search online for home-made jetpacks and you’ll find lots of ideas. Our basic design was: take a clean, dry plastic bottle (juice bottle, 2 liter soda, whatever) or two (if two, you’ll want to strap them together). Fill with bits of Poly-Fil. Put the lid on, then tape crepe paper flames (or felt flames) to the bottom of it. Take bias tape or other strings. Lay them on one side of the bottle in an X shape and tape it on. Decorate, adding buttons and such. Then tie on by putting it on the child’s back, and crossing the ties across the chest.

IMG_20160206_105015780  IMG_20160206_105021208 img_20170211_160952499

You could also make jet packs or walkie talkies or other “space gear” by covering cardboard boxes with foil and decorating.

Solar System Crowns. Cut long strips of black card stock. Measure them to fit around a child’s head with a small gap in the back. Have kids cut out paper suns to glue in the center. Then glue 8 (or so… ) glass “stones” on to represent the planets. After the glue dries, punch holes in the ends of the band, and tie a string between them so the child can wear it as a crown. We used tacky glue for this project, which works but takes a long time to dry. A hot glue gun would be faster. (Read Teacher Tom’s thoughts on allowing young children to use hot glue guns.) Note that we had a poster of the solar system and a diagram of the solar system out for information and inspiration.

Solar system: this year, we couldn’t find the large heavy black cardstock to make these into crowns, so we just had out big blue paper and stones… kids made some great solar systems with parent’s help.

Comet Streamers: We put out wooden rings and plastic ribbon so they could tie on streamers and make a fun toy to run and play with.

IMG_20160206_141425167

Rockets: We made rockets with card stock. (Click here for a printable rocket template to cut out and assemble. PDF also includes a pattern for making a rocket with craft foam)

IMG_20160416_155144012

You shape these rockets around a film canister, but then take the film canister out. Note: you can use these paper rockets with Alka-Seltzer rockets and launch these up 10 – 20 feet in the sky, but it will soak / ruin your paper rocket in the process… see details here.

Creation Station: We always have a collage station available in the corner with lots of fun recycled materials, tape, and glue where kids can build anything they want. Here’s one student’s rocket ship that she created on a whim.

Melted Crayon Art: Cover a griddle with foil, lay paper on top of the heated griddle, and draw with crayon – the wax melts on to the paper. The art inspiration is the book Going Around the Sun: Some Planetary Fun, which I review here. Ideally, we’d make space backgrounds, like in the book, then make colorful planets to place on those backgrounds.

Model Magic Planets – another project we considered was http://www.3dinosaurs.com/wordpress/index.php/model-magic-planets/

Science Activity: How much would you weigh on the moon: Kids were encouraged to weigh themselves on a bathroom scale, then look up on the chart how heavy they would be on the moon and on Mars. We also discussed this idea in circle. This was interesting to our older kids (6 and up) who have some grasp of what “5 pounds” feels like vs. what “60 pounds” feels like. But, way too abstract for little ones, really.

Sensory, Puzzles and Games – In the sensory tub, we had red Kinetic Sand for “the surface of Mars.” We just put in toy cars with good treads to leave marks. Even better would be Mars Rovers, like these from Hot Wheels or LEGO, though it might take a lot of work to clean all the sand out of the Lego. We put out multiple Solar System jigsaw puzzles, And the Goodnight Moon Game which is a simple preschool level ‘match the card to the picture on the board’ game.

Snack – Kids make something that looks like planets. You could use English muffins split in half that they spread on whipped cream cheese and swirl in food colors. Or make pizza planets on the English muffin. Or decorate round sugar cookies with frosting.

Or just serve the rocket shaped cheddar crackers and the star shaped yogurt-covered cookies from Trader Joe’s.

Opening Circle

Song: Zoom Zoom Zoom (here’s a video of librarians teaching the song)

Zoom Zoom Zoom, we’re going to the moon.
Zoom Zoom Zoom, we’re going to the moon.
If you want to take a trip, climb aboard my rocket ship.
Zoom Zoom Zoom, we’re going to the moon.
In 5 – 4 – 3 – 2 – 1, Blast Off!

Verse 2: Fun Fun Fun, we’re going to the sun

Verse 3: Far, Far, Far, we’re going to the stars

Question of the Week: Each week, we post a Question of the Week (or more than one) on the board. I define the question this way: When the youngest child in the class walks out today, they should be able to answer this question in at least a basic way. Our questions this week were: What is a planet? What is a moon? What is a solar system? The very simple answers are: Planets are worlds that orbit (go around) a star, like our Sun. A moon is like a mini planet that orbits around other planets, like our moon orbits the Earth. A solar system is made up of all the planets and other things (moons, asteroids, comets and such) that go around a star.

Tool of the Week – Models: Each week we have a featured tool. This is often something we’re using in activities, such as a screwdriver, a hammer, or a magnifying glass. This week, in circle we wanted to talk about the idea of Models, and how scientists build models to better understand things:

  • If something is too small to see (or to see well), we may make a model of it. (We reminded them of how we used Duplo blocks and our bodies to symbolize molecules in our states of matter lesson a few weeks ago.)
  • If something is very big or very far away it may be hard to conceptualize it and how it relates to other objects. Having a model can help.
  • When we want to build something complicated and expensive, we may first build a small “scale model” – a miniature version. This lets us test our ideas and problem-solve before we spend a lot of time and expensive materials on building the full-size version. (You could mention that there were lots of models built of spaceships as they worked on the design of what would eventually be launched into space.)

We demo’ed our orbital model, and our orbital mechanics model (see above.)

Night and Day: We turned on a lamp, and said it was the sun. We told them Teacher Cym was the earth, and we were all little people standing on her nose. She rotated to show them when the people saw the sun it’s daylight, but when she turns around, her nose is in her shadow, and it’s night-time for the people standing on her nose. After she demo’ed a few rotations, we had the kids do it. I think our 5 – 7 year olds understood the concept. Our 4 year olds had fun turning around, our 3 year olds didn’t get it at all.

Lunar phases: You could use a flashlight, a large Styrofoam ball and a small Styrofoam ball to demonstrate how the sun’s light (the flashlight) shines on the moon and what we can see from Earth. If you do this, here’s some recommendations: one – put a pushpin or something on the Earth to represent “where we’re standing.” First have a child just hold the flashlight shining at the earth. Rotate the Earth around to show whether it’s day or night where we’re standing. Then have another adult hold the moon and move that around the earth, and talk about what the moon looks like from where we’re standing. This is a tricky demo to manage the physical logistics of, so practice it in advance.

Or you could use the exercise described in the online teacher’s guide for Faces of the Moon. (See below.)

We talked some about space travel, and we ended by reading Roaring Rockets. (see below) Something for us older teachers to remember… most of the parents in our classes weren’t alive for the lunar landings, and most of our students weren’t alive when the space shuttle was flying. I’d love a young kids book on the Space Station or some of the private programs that are now working on space flight.

Pretend Play / Large Motor Activity

Rocket Ship: We set up a climber to be a rocket ship. (You could cover the mats in fabric to look more like a planet surface and less like blue gym mats.)

Mission Control: We had a variety of equipment set out on tables: joysticks, steering wheel and pedals from a driving video game, headphones, phones, keyboards, etc. We explained that some kids could pretend to be Mission Control on Earth while others went to space in the spaceship. (Click on the picture for a bigger image.)

Dress-Up Items: We set next to the climber a collection Space Helmets and a couple space suits (tabards with flattened aluminum pans on them.) They could also wear their jet packs they had made.

IMG_20160206_125431316

Moon Walking: We had large sponges (like you use to wash a car.) Rubber band them onto kids’ feet, then have them walk – it feels odd – maybe like ‘walking on the moon.’

Closing Circle

Solar System: We showed them an orrery – a 3-D model of the Solar system that shows relative sizes and orbits of the planets. Ours was this inexpensive kit from Amazon – the dime is in the picture to give you a sense of scale (note: if you get one of these, be sure to pay very careful attention to which length of metal pin each planet gets mounted on – if you get it wrong, it’s hard for them to orbit past it each other properly.)  This is for display only, as it tends to fall apart if three year olds pick it up and turn it upside down.

IMG_20160207_225848354

Planet Models: I have some model planets I made of Model Magic long ago. I brought them along for hands-on experiences during closing circle. They’re little (notice the dime for scale) and squishable so I had to tell the kids to be careful holding them and modeled how to hold them in their open palms, not squeezing them between fingers.

IMG_20160207_225942246

Book: We read Space Walk by Yoon, a nice simple lift-the-flap overview of the solar system with basic rhymes about each planet. In the morning class, we had some kids missing due to illness, so we happened to have exactly 8 kids. I gave each a clay planet. When it came to “their page” in the book, they showed everyone their clay planet, then gave it to me, then lifted the flap to learn about the planet. (In the afternoon class, we had more kids than planets, so did NOT hand out planets to anyone.)

Planet exploration: We used the orrery and the clay planets to talk about each planet – which is biggest – which is smallest – which is closest to the sun – which would be hottest – or coldest – which have rings. This is just to practice observation and categorization.

Dance Party: We got the comet streamers we’d made out (and we had extras for anyone who didn’t make one). We put on this YouTube video of Zoom Zoom and danced around, singing along and waving our comet streamers.  The video adds in this chorus: We can have a party on the stars with Mercury, Venus, Earth, and Mars. Jupiter might just sing a tune, with Saturn, Uranus and Neptune.

More Books

IMG_20160206_125239440

As always, I’ll give affiliate links for the books I recommend – the link allows you to easily go to Amazon, learn more and read reviews. (If you buy anything, I receive a small referral fee. But really, I recommend that you get books from your local library whenever possible!)

Space Travel:

  • Roaring Rockets by Mitton. A nice circle time book for ages 2 – 5, with simple rhyming text and a very basic intro to space travel.
  • I Want to Be an Astronaut by Barton. Another simple preschool book on space travel – frankly I like Roaring Rockets better because there’s a rhyme and rhythm to that book, which is lacking in Barton’s text. But again, another good illustration of the very basics of space travel.
  • Floating in Space by Branley – of the Hayden Planetarium. If you have a 5 – 8 year old who really wants to learn more about space travel, this is a good book for reading one-on-one, but way too long and detailed for use in class.
  • Papa, Please Get the Moon for Me by Eric Carle is a lovely bedtime book with Carle’s great trademark art style but it’s definitely fantasy not science.
  • Happy Birthday, Moon by Asch. Another gentle “bedtime-style” book where Bear imagines having conversations with the moon (really an echo). I read both these books to my son when he was three and again when he was five. At five he gets that you can’t climb a ladder and reach the moon and that the moon doesn’t talk to you and give you presents. But he still enjoyed these books, partially due to his delight in understanding that he has a more sophisticated understanding of how the universe works than these characters do.
  • Mousetronaut by astronaut Mark Kelly starts with a true story of mice aboard the space shuttle, but then moves into fiction. Fine read.

Solar System: There are many series of non-fiction books about planets, all of which have 8 books, with titles like “The Moon” or “Jump to Jupiter” or “Ringed Giant – the planet Saturn.” Go to your library, flip through them – see which series is best for your audience.

Books on Day and Night and Moon Phases

  •  Day and Night by Storad. Really nice explanation for 3 – 5 year olds. “Did you know we live on a moving planet? As the earth turns, it changes from day to night. The sun rises in the east and sets in the west…. Night is here. The moon rises. Some night we see a half moon…” Simple text, clear ideas, good photos.
  • Faces of the Moon by Crelin, ill. by Evans. Poetic text: “The moon’s first phase, we call it NEW – when Moon’s between the Sun and you. Her sunlit side is turned away, and we can’t see her, night or day” followed by a brief timing note: “New Moon rises and sets with the sun.” Illustrations are great, with a graphic design where cut-outs in each page show the phase of the moon. (See below.) The text is best for age 5 – 8, but I can see using the illustrations with younger children. Would be a great companion to a moon journal project. Includes an online teachers’ guide with a really nice group activity that models the phases of the moon by having a lamp in the center of the room to represent the sun and a Styrofoam ball on a stick to represent the moon. The child’s face is where they are on Earth. The child holds the moon in front of them, then they turn around (as the Earth does) and see how the light shining on the moon changes.

Take-Home Activity: We sent home a copy of this solar system mobile that kids could decorate, cut out and put together with parents’ help. (Note: making a mobile that balances is kind of an advanced engineering skill… )  It would be best to copy it on 11×17 card stock if that’s possible for you. There’s another solar system mobile here.

Follow-Up / Homework: If you’re homeschooling, and want to follow the Next Generation Science standards, 1-ESS1-1 is “Use observations of the sun, moon, and stars to describe patterns that can be predicted. [Clarification Statement: Examples of patterns could include that the sun and moon appear to rise in one part of the sky, move across the sky, and set; and stars other than our sun are visible at night but not during the day.] [Assessment Boundary: Assessment of star patterns is limited to stars being seen at night and not during the day.]”

A nice way to work on this would be with a Moon Journal: using a worksheet, each night (or most nights), take your child outside to observe the moon and draw it out. Over the course of four weeks, they’ll have a very “hands-on” experience of the way the moon changes. During this month, re-read a book on Moon Phases multiple times to help them integrate their new learning. Buggy and Buddy has a nice moon journal here. You may also ask an older child to notice that the details of the moon’s surface are more visible at some points in the moon phase than others. Learn more here: https://stardate.org/sites/default/files/pdfs/teachers/ObservingTheMoon.pdf

An Astronaut Birthday Party: Many of these activities could be adapted to a kids’ birthday party. I’d do the pretend play (make a “spaceship”, mission control, and some simple costumes), make jetpacks and paper rockets, then launch a few Alka-Seltzer rockets. With the cake, be sure to serve Astronaut Ice Cream.

Videos and Apps

You would think there would be good planet-themed apps. I haven’t searched recently, but two years ago, when I had a three year old who was wild about the solar system, I searched and searched and didn’t find anything worth bothering with. If you have one you like, add a comment!

Videos are a whole different matter! There’s lots of good ones. My son loved:

And more… these are all toddler / preschool friendly songs about planets:
