Kavi's Mystery Materials Bag
Kavi opens a mystery bag and pulls out a wood block 🪵, a sponge 🧽 and a plastic cup 🥤. "What can each one do?" A scientist makes a plan — press it, pour water on it, bend it — then predicts, observes and concludes!

What your child will learn
1Press it, pour it, bend itOur plan: test each material three ways — press it (hard or soft?), pour water on it (waterproof?) and bend it (bendy?). Predict first, then check!
2Sort by property: hard or soft?We pressed each material. Which ones kept their shape, and which ones squashed?
3Sort by property: waterproof or not?We poured water on each one. Did the water stay out, or soak in?
4Choose the right materialA scientist's conclusion: choose the material whose property fits the job! Tap each card.
🔍
A peek inside
We pour water on a paper towel 🧻. Is it waterproof?
Plan: pour the water. Observe: it soaks in. Conclude: it is not waterproof.
Try this at home: Press a sponge. Is it hard or soft?
