Youngest daughter keeps asking to do "experiments". Recently, we investigated ice and melting using an idea from a DK science book, "In the Garden".
I've been really impressed by some of the ideas in the book but this idea around freezing and melting was particularly good-home ingredients, little mess and results that were fun to observe.
We half filled a muffin tray with water. We used tap water although the book suggests rain water. I didn't know how long I would have to wait for rain. We then put in pieces of flower and leaves in the water and a loop of string in each hole.
The flowers have strange tints as they were previously used to look at transport in plants, using coloured water.
The muffin container went in the freezer for half a day, we took out the finished product and hung it outside and talked about how long it would take to melt.
This current interest, probably stemmed from our cell model using jelly for cytoplasm, a truffle for the nucleus and various other sweets for other organelles. Thank you to Apologia for this idea.
