Holding the hand-boiler...

| The children were amazed. |
Metal, wood and plastic spoons in hot water.
Chocolate chips holding on...
Why did the chocolate chip slide off of the metal spoon?
We had another fun science class with Dr. Rosler,
a.k.a. Science Mom.
She did an awesome experiment on equilibrium (great words for "E" week). She explained how molecules "huddle together like penguins" when they are cold and how they "separate or stretch apart when they are hot like an erupting volcano".
We observed a demonstration on how heat rises by using different colored solutions.
The children got to hold a hand-boiler and watch how the heat from their hands made the water bubble up through the tubes.
Using 3 spoons (metal, wood and plastic), butter and chocolate chips, we observed that heat can move through things. Only the chocolate chip on the metal spoon slid off because we learned that metal conducts heat.
How lucky are we to have such great learning adventures in science? Thank you Dr. Rosler!
