Today we discovered that vibrations can be seen as well as heard(as sounds) or felt.
In this example, we hit a tuning fork on a table leg then quickly put it in a bowl of water. The vibrations made ripples in the water and sprayed it across the table.
Over the last couple of weeks we have considered heating and cooling in a variety of ways.
We enjoyed heating chocolate (solid) and melting it until it had the pouring properties of a liquid. We then witnessed that if you cool it down again it will become solid again.
In addition to this, we tested the melting rates of three solids wax, butter and chocolate button. We found we didn't have water hot enough to melt the wax.
