SCIENCE QUIZ POSTPONED - New Date Wednesday, February 1, 2017
The Grade 3’s will be having a science quiz on Tuesday, January 31, 2017. For the quiz, students need to know the following:
· Understand the importance of a structure’s form, strength, and stability
· Understand how a structure is affected by form, strength, and stability
Success Criteria
I can…
✔ understand the science vocabulary words used in this unit and use them appropriately
✔ tell the difference between structures that are made by humans and structures that are made by nature
✔ list examples of structures made by humans and structures made by nature
✔ describe ways a material can be made stronger (folding, adding layers, twisting/braiding, changing the shape (triangles))
✔ describe ways a structure can be made stronger (triangles, cross beams, trusses, struts to avoid compression, ties to avoid tension)
✔ describe ways a structure can be made more stable (lower the centre of gravity, make it shorter, balance material)
