Cornstarch Science - Quicksand Goo - The Lab. How Does It Work The cornstarch and water mixture acts like a solid sometimes and a liquid at other times.
This concoction is an example of a suspension (a mixture of two substances), one of which is finely divided and dispersed in the other. In the case of the cornstarch quicksand, it’s a solid dispersed in a liquid. When you slap the cornstarch quicksand, you force the long starch molecules closer together. The impact of this force traps the water between the starch chains to form a semirigid structure. Take It Further Pour the mixture onto the cookie sheet or cake pan. IMPORTANT - Read This! The cornstarch will not stay mixed with the water indefinitely. Steve on The Ellen Show In an effort to live out our mission (“Make It Big, Do It Right, Give It Class!”) How to Simulate the Rock Cycle with Crayons - Navigating By Joy. We’ve done two hands-on earth science projects this week – on Monday we made model planet Earths out of clay, and on Thursday we simulated the rock cycle using wax crayons.
Both were great fun, and both reminded me that these kind of projects take more time and effort than I anticipate when I read about other people doing them! This post is about our experience doing the rock cycle. I hope my usual “what we might do differently next time” section will benefit you! Before the Activity We’ve been learning about the rock cycle and different types of rock over the last few weeks. By now, all of us have Mr Lee’s Rock Cycle Rap stuck in our heads (highly recommended. Just before we did the activity we watched the Rock Cycle Brainpop video and looked at pictures of the cycle in National Geographic Kids Everything Rocks and Minerals.
I strewed three rock samples on the table and told the kids one was sedimentary, one metamorphic and one igneous. What We Used Simulating the rock cycle – What you do. How to Stack Liquids in a Rainbow of Layers, a Fun Kid Science Project. Do your kids like to stack blocks into tall, gravity-defying towers?
Ever try to stack liquids without letting them mix? It’s easy and oh-so-cool! You just need a little chemistry know-how and a steady hand. In this article I’ll show you how you and your kids can stack seven liquids into a rainbow of layers, one on top of the other, without mixing them. It looks like magic, but it’s not—it’s science! Why Stack Liquids? It’s important to teach kids basic scientific concepts so they’ll understand how the world around them works. When you make it fun or exciting or even jaw-droppingly awesome, you capture kids’ attention, pique their curiosity and make them want to learn more. Stacking liquids achieves all three.

Today, Vicky and I are each sharing a FUN Halloween Activity. Flying Ghost Rockets Halloween Activity Have you ever made Alka seltzer rockets? Flying Ghost Rockets Materials List (affiliate links provided) Film canisters (we ordered the ones made for kids to use in Science activities- 12 for only $6)Corn starchWaterA black marker Alka seltzer ( we used the off brand tablets they sell at Dollar Tree and they worked great!)
Once dry add a bit of corn starch to each film canister and then fill roughly 1/3 of the way with water. Then it is time to PLAY! You will want to set off one ghost rocket at a time. The ghost rocket will go flying high into the air These ghosts really fly high, too! Just look at the force of Science that propels them. Pepper Dish Soap Experiment.
