Here's what I did for this fun game that really kept my Spanish immersion students engaged in practicing some tough science vocabulary on light.
1) A student brought in two plastic strawberry baskets. I cut one side off of each, so they could be positioned like soccer goals.
2) Then I made some Avery #5410 labels with our light unit vocabulary. I put the definitions on tops of bottle caps and the terms on the inside of the caps.
Rules of the Game:
1) To play, students place the "goals" on opposite ends of the table.
2) Taking turns, they choose a bottle cap, read the definition, and name the corresponding term.
3) They check their answer on the inside of the cap, and if correct, they can take a shot at their opponent's goal by flicking the cap with their finger. If it goes in, they win the cap. If it doesn't, they return it to the pile. If they don't know the definition, they return the cap, and it's the next person's turn.
(Casi! The heart box in the background serves as the storage container for the caps.)
4) Continue playing until all caps have been won. The winner with the most caps wins.
This game is fun, free (except for the Avery labels), and good for the environment. Give it a try!
