## Rotate or Revolve

#### Rotate or Revolve

###### Media: A Closer Look at the Moon

Visual learners will 'get' the abstract concepts of difficult vocabulary terms (rotate or revolve) as they practice and apply what they saw and heard in the video during this engaging classification exercise.

This activity is designed to help reinforce the difference between the concepts of rotate and revolve. Students will see different examples of objects rotating, revolving, or both. Students will choose which word describes the motion of the object. When you click on the "Start" button to begin playing, a picture of an object or objects will appear onscreen. The objects will be rotating, revolving around another object, or both. Click on the appropriate answer button. If you answer correctly, you will hear a positive audio cheering response. If you answer incorrectly, you will hear a buzzer. You may try again until you get to the correct answer. When you have correctly identified the motion of all the objects, the game ends.

Before playing the game, have students watch the video "A Closer Look at The Moon." This game can be played as a class, in pairs/small groups or individually.

• Whole Class: Divide the class into two teams. Assign one student to be the "game show host" who will decide which team will answer and will click on the answer provided. Assign one student to be "scorekeeper" to keep track of the points scored by each team. When the game show host clicks to start the game, the first person to raise his/her hand gets to answer first. If that person gets the answer correct, his/her team will earn a point. If he/she gets it wrong, the other team gets a chance to answer. All: Another way to play the game, without teams, is to have the "game show host" click to start. Allow students to vote on the correct answer with either a show of hands, yelling out their answer, or applause for the answer they believe is correct.
• Have groups of students move into a configuration of the Sun, Earth and Moon (inside or outside). Have students spin (very slowly!) and have other students revolve. (Kinetic modality) Have objects that spin and objects students can revolve around other objects. Have students research how other planets and moons in our solar system revolve and rotate and compare them to the relationship that the moon has with the Earth and the Earth has with the sun.

History: Students can research why it was believed in the past that the Sun moved around the Earth. What changed the belief? Who was and what happened to Gallileo?
