How would you find a volume of an irregularly shaped object, for example, a golf ball?
Fill a cup with water and mark the line. Then put the golf ball in the cup and mark where the water moved up to. Finally, pour the displaced water into a graduated cylinder and measure the amount of water to find the volume of the golf ball.

Draw a model of what happens when ice cream melts. Label the model
Check drawing and labels. Show heat source
200
Draw and label a model to demonstrate how particles are too small to be seen. ex. peppermint filling the room
Draw a source of odor, particles of a gas moving to fill the room, and labels and arrows to show how the odor spreads

Does sugar disappear or dissolve when mixed with water? HOw can you prove it without tasting it?
It dissolves. Weight the cup of water, add the sugar, weigh the cup of water and sugar. It should be more weight, proving the sugar is still there.
300
A material that easily shares or absorbs heat or electricity.
Conductor

liquid to solid
Freezing

What happens when a solid turns into a liquid?
increase in heat causes particles to heat up and move quicker and turns into a liquid. (melting)

How would adding air to a ball help when playing basketball?
When adding air to the ball it increases the volume and will inflate the basketball making it bounce better.

Listen to Mr. Edwards and Mrs. Edwards opinions. Who do you agree with and why?
Mrs. Edwards: warming of the sun causes a phase change form a liquid to a gas and how the water level will decrease due to evaporation.
