Kindergarten Science · World 5: Sink or Float Bay · Level 30
Big Isn't Always Sink
A big log floats and a tiny pebble sinks.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 30
- Do big things always sink? Let's test! A big log floats.
- A tiny pebble sinks!
- So size alone doesn't tell us. A big watermelon floats, and a small coin sinks.
- We have to test to find out!
- Try it with a grown-up! Find a big thing that floats and a small thing that sinks.
Georgia Standards of Excellence in Science:
- SKP1.c — Plan and carry out an investigation to predict and observe whether objects, based on their physical attributes, will sink or float.
