A big part of second grade is exploring the world around us. We do that in Science by studying what makes up the Earth, and figuring out how things move or are created. We also learn about the actual make up of the Earth, particularly its crust and how it is made up of tectonic plates.
In Social Studies, we learn all about the different countries that make up the world we live in. We pay close attention to the countries of the people we spend time with — our classmates. Thankfully, the parents of our classmates and friends are very generous with their time and come in to tell us all about their homelands. We learn so much from them, it really is quite exciting!
To learn about tectonic plates and how these piece of the Earth’s crust move along, we got creative and used food! This was particularly appealing to the children, as they were allowed to have some of the crackers and condensed milk to eat after conducting the experiment :p
The pieces of graham crackers served as the tectonic plates of the Earth’s crust. The condensed milk served as the molten lava that holds up the crust. What happens when the pieces slip and slide against each other? The children tried to mimic the movements of the plates using the crackers, and learned about how the different plates could possibly move. It was a fun, albeit sticky, afternoon!
There’s More to Belgium than Belgian Chocolate!
Our friend’s parents came in to talk to us about their home country of Belgium. They taught us about their flag, the different things you can do there, and even told us about a famous cartoon that originated from their country (The Adventures of Tintin)! We also learned that they speak a bunch of different languages in their country, depending on what part you live in.
The best part of their visit though is that they brought us a bunch of Belgian chocolate to have! It was so good
Erosion and Weathering
Science is definitely a hands-on, experimenting type of subject. We learn best by observing the things around us, and getting our hands dirty. When we learned about weathering and erosion, we literally got our hands dirty as we explored what would happen with soil if we continuously blew against it with straws, simulating the way the wind moves past rock and dirt structures. Boy did we learn just how strong the wind is!
