When something feels hot to you, the molecules in that something are moving very fast. When something feels cool to you, the molecules in that object aren’t moving quite so fast. Believe it or not, your body perceives how fast molecules are moving by how hot or cold something feels. Your body has a variety of antennae to detect energy. Your eyes perceive certain frequencies of electromagnetic waves as light. Your ears perceive certain frequencies of longitudinal waves as sound.

    Do you know where the worksheets for this experiment is?

    This particular experiment doesn’t have a worksheet, however you can create one of your own using the guidelines under the Science Journal. You could try different kinds of dye, different temperatures, etc. Have fun!
