Fizzing Jupiter

For those of you who follow my activities, you know how much I love my baking soda and vinegar experiments. ¬†To be fair, the tots and my littlest superhero LOVE baking soda and vinegar so it’s not ALL about me ūüôā

This one is a simple and easy addition to your space theme. ¬†I call them Jupiters (even though my color mixing wasn’t as successful as Jupiter) but you could make them any planet or leave them white for the moon.

Here’s what you need to get started:

  • Baking Soda
  • Water
  • Measuring cup
  • Large Mixing Bowl
  • Tray for drying the rocks
  • Vinegar
  • Black or purple¬†food coloring (optional – but colors make everything more fun!!)

To make the planet:

Combine 2 cups of baking soda and 1/2 cup of water (add the desired color to the water) in a large bowl.  To make the the Jupiters, I split this into two bowls, one with red (looked orange) and one with yellow.

Then I mixed both together to get an orange-yellow swirly Jupiter look.  Kind of.

Using your hands, take a handful and roll into a ball. ¬†If it’s too dry, it won’t stay together, if it’s too watery, it will melt into a sloppy puddle. ¬†Add water or more baking soda to adjust the consistency. ¬†

Let them dry overnight.  I placed mine in a plastic container and put them in the freezer to harden. 

The next morning, the planets were hard.    Note: this recipe will yield about 10 balls.

To explore:

I gave each little one a “Jupiter” and a cup with vinegar that had black food coloring and some silver glitter (“Starry Space Juice” is what I called it!).

The tots definitely know what to do with the dropper and the vinegar.  Space juice was added to the planets for some fizzy fun!

Such an easy and simple little experiment to set up!

Science behind the Activity:

This is a twist on the classic baking soda and vinegar experiment.  Baking soda is a base and vinegar is an acid.  When combined, they release carbon dioxide gas (the bubbles).  The fizzing and bubbles are just way too much fun for the kiddos!

Galaxy in a Bottle

So this isn’t really a science experiment but I LOVE discovery bottles and this one is so pretty! ¬†My older boys really enjoyed making this and it led to discussions about supernovas and galaxies and nebulae. ¬†The tots in my class enjoyed the pretty swirly colors and filling¬†the bottles.

Here’s what you need to get started:

  • cotton balls – almost a bag per bottle
  • empty bottles (I used old gatorade bottles)
  • paint in “galaxy colors” (we used metallic acrylic paint in purple, silver and blue)
  • glitter
  • straw (or something to push the cotton balls into the bottle)
  • cups

First, create the colors of your galaxy by adding some paint to water.  We used metallic blue, metallic purple and metallic gray.  We love how swirly the water looked!

Next we stuffed our bottle about 1/2 full with cotton balls. ¬†(It looks prettier if you shred the cotton balls, but my boys and the tiny tots don’y have the patience for that!) ¬†We used a straw to help push the balls into the bottle.

Next, add your first color to the bottle.

Add some glitter.  (We probably should have added more)

img_8248

We noticed that as soon as the water was added, the cotton squished into a smaller layer.  So add lots of cotton! Like we did on the second layer.

We again added a new color to the cotton.  And more glitter.  Make sure to push the cotton down as tight as you can.

We repeated it again with the last layer.

Then we added the lid and shook it a bit.

The puffy cotton looks like the “clouds” of space debris you see when you look at pictures of galaxies, nebulae, supernovas, etc… The glitter looks like stars in the night sky…

While we were making these bottles, my boys asked me what a galaxy was and what a supernova was. ¬†It was a great art activity to open up discussion about outer space. ¬†While not a real science experiment, it sparked a science conversation. ¬†It my book, that’s success!

Pie Plate Model of Earth’s Orbit

**Updated! 10/18/2016**

I have been meaning to to do a space themed lesson for a long time but was struggling to get some science activities (not just crafts) for the youngest set to do. ¬†I finally “landed” on this one and it was fantastic fun and so easy to do!

Here’s what you need to get started:

  • Foil pie plates (must be round)
  • Black construction paper
  • Orange construction paper
  • Star stickers
  • Blue Marble (or blue-green, to represent Earth)
  • Glue
  • Scissors

img_8576

Since the tots in my class are pretty young, I measured out the bottom of the pie plates and cut out black circles for them.  I also cut out the orange circles to represent the sun.  For preschoolers and kindergarteners, I would definitely trace the circles for them but have them cut them out on their own.  For older kids, they can trace and cut on their own.

Glue the large black circle to the inside of the plate.  This represents space.

Next, glue the orange circle to the center of the plate.  This represents the sun.

img_8578

Place some stickers all over the black paper to represent the starts in the sky. As was noted by a fellow science teacher, there are no stars in our solar system except for the Sun.  To make this activity scientifically accurate, you might just want to skip the star stickers.

Lastly, add the blue marble and spin the plate so that the marble spins around the edge of the plate, representing how the Earth spins around the sun.

img_8598

That’s it! ¬†It’s a craft, but there’s plenty of learning (and fun) while spinning the plate.

The Science behind the Activity:

There are plenty of models of the solar system but I love how this is so simple for young kids to understand that the Earth is moving around the sun and not the other way around.  This same project could be done with the Earth in the center and a white marble to symbolize the moon spinning around the Earth.

*My only note on the original author’s post is that scientifically it’s not accurate to place 8 marbles in the pie dish to represent all 8 planets orbiting the sun. ¬†The sizes of the orbits are very different and the planets would be showing that they are crashing into each other. ¬†But her idea is great for showing one orbit at a time.*

**Updated: Skip the star stickers if you want to be scientifically accurate.  There are no stars in our solar system.  The only star in our solar system is our sun.**
