Objective
By the end of this lesson, you will be able to understand the concept of sink and float and identify objects that sink or float based on their characteristics.
Materials and Prep
Materials needed: a tub of water, various objects to test (e.g., coins, paper clips, plastic toys, rocks), a pencil, and a notebook to record observations.
Prep: Fill the tub with water before starting the lesson.
Activities
1. Predict and Test: Predict whether each object will sink or float, then test it by placing the object in the water.
2. Record Observations: Use the pencil and notebook to write down whether each object sinks or floats.
3. Experiment with Buoyancy: Try to make some objects that initially sink float by changing their shape or size.
