Grade 3 is finishing up our unit on How the World Works, where students learned about various natural disasters during the unit. This week, we experimented with different ways to make a volcano explode. The students experimented using two different methods. The first one was with Coke and Mentos. They only saw a small reaction, which was due to the soda being in a cup and not in a bottle. The second way was using baking soda and vinegar in a cup. This time the students saw how lava would come out of a volcano. It was also a great way for them to see that not all Science experiments work on the first try or how they see them on the Internet. The students also made a Tornado in a bottle using 2-liter bottles, water and blue food coloring. They were really surprised to see how a tornado can be made using these supplies. It was a fun day for them!
We also finished up our Geometry unit in Math this week. We took all of our knowledge to solve riddles, draw shapes, play a matching game and draw a city made only from geometric shapes learned. This was a great way for the students to finish the unit and work together to problem solve!
