I will take
the children in groups of 6 to the staffroom. On each saucer I will
put a small amount of cheese, chocolate, butter and ice-pop. Into
each glass I will put some salt, coffee, sugar and sand. Through
What are these? Can I pick them Up? Can I pick up the water? What
will happen?) words such as "spill", "pour",
"flow" and "melt" are introduced. Pictures of
these solids are taken at this stage before heat is applied.
Development - Changing
Solids to Liquids
I change these solids? (by heating). We will use the microwave to
illustrate this with some of the solids. We will add
hot water to the other solids in the glasses.
How have solids changed? Why? What has happened to the sugar? Has
it changed - disappeared? It has dissolved. What has happened to
the cheese, butter etc? Have they changed? They have melted - become
a liquid. What has happened to the sand? Has it changed?
We will use
the digital camera to take photos of the food items after they have
changed. We will discuss the change from solids to liquids (before
and after) using the pictures to revisit the concepts learned.
