3. 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. 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 team’s ships wins. The RED team must sink purple ships and the PURPLE team must sink red ships. (if you’re playing at home to review, click on ‘answer’ for the correct response) Each team or the team captain must be told which squares hide their ships. (see notes below this slide) Get out your reference tables. Let’s play!
