Today in science we learned about gravity, tension, and compression. We found out that even though these forces are invisible, they are the ABC’s of structural engineering.
Today’s Challenge: Design and build a structure that demonstrates tension in some parts and compression in others.
Materials: 2 cardboard squares, 12 straws, 12 straight pins, 1/2m of masking tape, and 1/2m of string
The students did a fantastic job of working together. They are learning so much!
Joint construction and strengthening materials are next.
Dear Mrs. Watson’s 2/3 Class,
Wow – another great video of your engineering in action! I really enjoy watching these because I get to see how you work together and how your ideas develop. One great thing about science is that even if your ideas “don’t work” you still learn a lot. Sometimes I learn more from my ideas that don’t work, than from the ones that do. Either way, it is obvious that you are all learning a lot!
Did you find that any material was better than the others, or that one material wasn’t very useful?
From,
Mr. Salsich
