Plasticity Lab Conclusion

Currently in science class, we are learning about the Earth’s interior. Recently, my class performed a lab on the mantle. We mixed cornstarch and water together, which resulted in a substance that is gooey and very fun to play with. This mixture is both a solid and liquid. When heat and pressure are applied, you can roll it into a ball, like a solid. However, if you let it sit in your hand it will slip and slide, like a liquid. When handled, the mixture turns into a solid. When not handled, it’s a liquid. This is an accurate example of the Earth’s mantle because like the mixture, the mantle is solid when heat and pressure are omnipresent. However, the mantle turns to liquid form when heat and pressure are not omnipresent. This was a very interactive and fun lab, and I had a great time completing this hands-on experiment. Omega science is exciting and interesting, and I really enjoy participating in my science class.
