HTHT own Jet stream Julie went to Woodland Heights Elementary School in Mooresville, NC to teach a after school enrichment program to students in grade K-5.
Today at Woodland Heights, our junior scientists set out to explore the wondrous world of matter! First students raced water molecule cars! Here we study the act of cohesion, or “liquid sticky.” We used a paper race track, a piece of wax paper, q-tips and food colored water. This is especially fun when you have access to a whole roll of wax paper and the length of a cafeteria, this way kids can race side by side!
Later we look at mixing a solid (baking soda) a liquid (vinegar) to create a gas (C02) Using a small cup that has a couple of Tbs of vinegar, our scientist used their strongest pinchers to drop our solid into the cups AND BAM!! C02 bubbles arise! Now because we encourage safe cleaning and learning, we mention to students that this is a safe, inexpensive way to clean sinks and drains. Junior scientists get to this on a larger scale and score points with mom for cleaning. 👍🏻👍🏻
Next, we made our famous space mud. We plan to mix three liquids to make a semi-solid. We start with a small cup of glue, followed by a few drops of our favorite food coloring. Then we add a liquid borax solution, and then we stir stir stir! The best part is we get to get our hands dirty! Putting our hands down in the cups we pull out our dripping mud. We roll it all around and squish out all the water forming a ball.
This is always a winning program exploring solids, liquids and gases.
Has your child ever asked you a “Think About It” question before. You know, the ones that maybe you didn’t know the answer to or the one that you could sorta answer, but couldn’t explain right? Then when you get home you have to get online and find the answer, and then try to explain it to them. Well, I am sure that we all have been in that position before.
Well on Think About it Thursday, we are going to answer those questions that you’re not sure about! This weeks question is, “Why do Volcanoes erupt?”
Volcanoes erupt when gas bubbles inside magma, or hot liquid rock, expand and cause pressure to build up. This pressure pushes on weak spots in the earth’s surface, or crust, causing magma to exit the volcano.
Check out our online Volcano recipe that you can do with your child at home. This way your child will be able to see a Volcano erupt right before their eyes!
If you have any “Think About It” questions, you would like to know the answer to, then ask your question in the comments section below and once a month we will answer your question!

Space– Space is the boundless three-dimensional extent in which objects and events have relative position and direction. There are many things we don’t know or understand about space. So, we are going to give you a few fun facts! You can also check out of Fun Fact Friday website for more fun facts! https://sciencemadefun.net/blog/category/fun-fact-friday/
Then, go to our website and check out the great space experiments that you can try! http://sciencemadefunwnc.net/experiments.cfm
