When the students worked on building structures with straws last week, they learned that the best shape to support a structure is the triangle. This week, they learned about other factors that can influence the strength of a structures, such as the loads upon them, the forces acting on them, and the materials out of which they are made.
They used the Building Big site on the laptops to learn more about how each of these can have an impact. Then they identified vocabulary words to add to Haiku Deck presentations about Forces and Loads. After presenting what they learned, the class participated in a “Space Race” quiz using the iPads. In partners, they answered questions. As they answered correctly, they could watch their spaceships cross the screen in the front of the room. They did very well!
2nd grade also learned that they will be going on a field trip on February 24th to the Insect Expo downtown. They will get an interactive tour of the Expo, and will be able to taste bee honey and participate in the live insect petting zoo. Parents, please be sure to sign the permission slip, which I sent home today!
