Today we will learn about Sink and Float
Toddler:
Give them a group of bath toys and drop (plop) them in the water one by one. Be very animated as you announce wither each items "sinks" or "floats".
Preschooler:
Ask your preschooler to help you fill a small basket with household objects that you don't mind getting wet. Ask them to guess if they will sink or float in water. Explain that floating means they stay at the top of the water and sinking means they will stay at the bottom of the tub (bucket, pool, container etc) After you have gathered objects bring them into the tub.
Experiment by dropping them one by one in the water. Ask them if it sinks or floats. Do they notice anything? Do you??
Advanced: After their bath, have your child draw a line down the middle of the paper and make a list or pictures under the headings :SINK FLOAT
