Try it with your learner
1. Gather a slice of white bread, a plastic bag, and a damp cloth. 2. Wipe the damp cloth on different surfaces around your home (like the table, door handle, and remote). 3. Place the bread slice in the plastic bag and label each side with the surface name. 4. Seal the bag and leave it for 3 days at room temperature. 5. Observe the bread — which side grew more mold? Discuss why! 6. Share your findings with family and talk about how to keep surfaces clean.
