Read all the directions and answer questions as you go along the steps.
1. Sort all the cubes by color. These cubes now represent ELEMENTS.
2. What do the individual cubes in each color represent? ___________________________________
Info:
When we stick the cubes together we are representing BONDS between the atoms of different elements.
When 2 or more elements are chemically bonded together the matter is called ________________________
These atoms bond together by electrical forces between their ELECTRONS.
Try This Example:
Stick a green cube on a white cube. You have now made “Green-White” and you can call it GW.
Now try sticking TWO green cubes on one white cube, you have made Green-Green-White. You can name it G2W.
3. Using the cubes, make THREE different compounds, and write their names.

Take the THREE compounds you just made and place them in a baggie.
5. What type of matter (element, compound, mixture) is in the baggie? Explain your answer.
