  1. How are liquids that you drink alike?
    • They can all be poured
    • They take up space
    • They take the shape of the containers they are in.

 

  1. How are liquids that you drink different?
    • They are different colors and tastes.

  1. Some toys are filled with air. Make a list of toys that need air.
    • Balls, blow-up toys, kites, pinwheels

 

  1. What does it mean to melt?
    • Melting means to change from a solid to a liquid.

 

  1. What makes ice melt?
    • Heat of the Sun

 

  1. What can heat do?
    • Heat can make things get warmer.
    • Heat can make things change.
    • Heat can change a solid into a liquid.

 

  1. How can you make a liquid turn into a solid?
    • Put the liquid in the freezer.

 

  1. Where does the water from puddles go?
    • Water from puddles spreads out into the air and becomes a gas.

 

  1. How does a liquid change into a gas?
    • Heat makes it change from liquid to gas.

 

  1. What would happen if liquids couldn’t change into gases?
    • Nothing would dry.

 

  1. What is the water cycle?
    • Starts off as a puddle of water.
    • Heat from the Sun warms the puddle of water and changes into a gas.
    • The gas spreads out into the air and turns into clouds.
    • Then it may fall down as rain.
