Talk together

Which pair is the same material?
What did the sun change?
How do these results compare with water?

Get ready

Six shallow matching trays, clean play sand, clean potting soil and large smooth rocks; Week 19 water results.

Safety

A grown-up stays close. Never look at the Sun; use hats, sunscreen and shade breaks. The adult checks surfaces first; do not touch anything hot.
Do not eat test seeds, plants or materials. No tasting is needed; check allergies and wash hands.

How to help

Let your child listen, look and try before you explain. Point to the next picture if needed. Accept drawing, pointing or a voice response; writing is optional. Save the child’s own work with a date.
