Simple investigation. Simple materials. I've adapted one of my favorite investigations so that families and students can be successful completing investigations OUT of school.
Topic: Relative density to water, buoyancy
Activity: Determine whether natural objects sink or float then build a raft to help a sad stone escape the deserted island.
Day 1: Conduct an investigation to determine whether objects sink or float.
Day 2: Build a raft from natural materials to help a stone escape from a deserted island.
Day 3: Choice Activity
• Materials from outside
• Small tub of water
• A small stone (sad face optional)
• Timing device
