Grade 2 Science · World 4: Matter Market · Level 24
Bendy or Stiff, Strong or Weak
Test flexibility and strength.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 24
- Flexible things bend easily without breaking, like a rubber band or a garden hose.
- Stiff things don't bend. Try to bend a brick, and nothing happens!
- Strength tells how much something can hold without breaking. A thick rope is strong. A thin thread is weak.
- To test strength fairly, hang the same weights on each string, one at a time, until it breaks. The one that holds the most is strongest.
- Your turn! Sort these: flexible, or stiff?
Georgia Standards of Excellence in Science:
- S2P1.a — Ask questions to describe and classify different objects according to their physical properties. (Examples of physical properties could include color, mass, length, texture, hardness, strength, absorbency, and flexibility.)
