How to play Earth Science Battleship
Divide the class into two teams, Red and Purple.
Choose which team goes first.
The main screen is divided into 49 boxes. The
first team chooses a box by letter and number, E4
for instance.
Each team or the team captain must be told which
squares hide their ships. (see notes below this
slide)
Click on the Q at the center of the square.
Be careful to click only on the Q. A question
will appear.
IF the team answers the question correctly, click
on return to board. This will take you back to
the main game board.
Now click anywhere else in the box (except the
Q). The box will disappear and you find out if
you hit and destroyed one of the enemy ships.
If the team did not answer the question correctly
simply return to the main board and allow the
other team to choose a box and answer a question.
The first team to successfully sink all four of
the other teams ships wins.
The RED team must sink purple ships and the
PURPLE team must sink red ships.
