Earth Day Oobleck Science Activity for Kids
Science and sensory play together! Our quick and easy oobleck is perfect for Earth Day science and sensory play. This Earth Day oobleck is fun science! Here’s how to make Earth Day oobleck and open up some dialogue about the importance of Earth Day. Make sure to check out our colorful oobleck sensory science play too for a different take on the classic science experiment.
Earth Day Oobleck Science and Sensory Activity
Oobleck is a mixture of cornstarch and water. Roughly a 2:1 ratio but you can tinker with the ratio to find a desired consistency that still maintains the properties of oobleck. What’s the science of oobleck? Well, it’s a solid. No wait it’s a liquid! It can be picked up in a chunk like a solid, but then it takes the shape of the container it’s put in like a liquid. This is called a non-newtonian liquid, a substance that acts like both a liquid and a solid.
Cornstarch, Water, Food Coloring, Bowl and spoon, tray or pie dish, skewers or toothpicks or even little trucks!
Mixing Earth Day Oobleck
To start our Earth Day oobleck activity, I mixed up two batches of plain white oobleck. I used about a coup of cornstarch and 1/2 a cup of water. Mix the food coloring into the water before pouring it into the cornstarch. You can see the right consistency. It will be tough to mix like a solid but then starts to flow into a liquid.
I emptied the two colors of oobleck into a pie plate to represent the Earth. He chose his construction vehicle utensils to play in the Earth Day oobleck. I thought some shells and rocks would be fun to add to the Earth Day and construction theme!
Our Earth Day Oobleck science became a construction sensory play activity as well as a science activity!
He asked if the oobleck was both a solid and a liquid. I demonstrated how you could pick it up like a solid, but it also takes the shape of the plate when you put it back down. I love how much he remembers from our science experiments!
Sensory play can also open great conversation opportunities!
Earth Day Oobleck science activity is perfect for talking about the Planet.
Make sure to ask plenty of questions to spark curiosity!
Ask questions while you sit with your child or play with your child. We talked all about Earth Day. I asked him questions to see what he thought the meaning of Earth Day is, what things can be recycled, what can we do to help the Earth, and so much more. Oceans cover more of the Earth than land. I already know that mom, was the answer I got! We really did have a great time sitting together and talking about Earth Day while engaging in our Earth Day Oobleack sensory play!
