Explore the moon in the comfort of your kitchen!
Let’s dive into the world of moon rocks! Make sure you have lots of supplies on hand because children will love to do this experiment over and over, watching the moon rocks slowly dissolve. Experiment with different liquids; what makes the rocks dissolve the fastest and slowest?
👆 Pro Tip: An eyedropper is a great way to control the moon rocks from dissolving all at one. Children love to dump and pour things so control the experiment with a slow-release eye dropper. Bonus: kids can practice their fine motor skills!
🎉 Vinegar Party! Sounds pungent! Explore how different kinds of vinegar react to the baking soda. Malt, white, rice, red wine...which vinegar dissolves the fastest?
🌎 All About Meteorites: Kids will be curious; what would happen if a rock fell from space onto the earth? Would it dissolve before it hits the ground? Explore this topic more and open the conversation around the atmosphere!
For this activity you will need:
Black, blue and purple food coloring
Eyedropper/meat baster/squeeze bottle
Reflecting and Reaching Conclusions
Describing similarities and cause and effect in recurring events
In a bowl, combine several cups of baking soda and colored water until you have a clumpy texture. Depending on your ratios, you may need to experiment with how much colored water and baking soda you need.
Once your mixture is clumpy, start forming small balls. Children will love this part!
Place your moon rocks on a sheet and place in the freezer for several hours.
Once frozen, place the moon rocks in a shallow bin and slowly drop vinegar from your eyedropper onto the rocks and watch the magic unfold!
⬆️ For older preschoolers: They’ll love to experiment with different kinds and amounts of vinegar. Maybe a small amount of malt vinegar dissolves a rock while you need a larger amount of rice vinegar to dissolve the same size rock...why?
⬇️ For younger toddlers: Younger children will love the cause and effect reaction the vinegar and baking soda have. After you’re finished with this activity, you can throw a few space-themed objects in and dilute the vinegar with more water to make a sensory bin!
Have you ever seen a rock from the moon?
Have you ever seen a meteorite land on earth?
What do you think would happen if we only put one drop of vinegar on our rock and let it sit for a while?
What would happen if we tried this experiment with different liquids like lemon juice or water?
What would happen if we tried this experiment on a rock we find outside?
