  • Finding the Center of Gravity Activity
    without touching other objects Discuss the ways that they balance themselves and have seen other people shift their center of gravity in order to achieve balance Procedure Part 1 Student Groups Predict and record where the meterstick will balance on a hand Balance the meterstick on a hand Record the results discuss and record your conclusions Put a ball of clay on the meterstick 15 cm from the end Predict and record where the meterstick will balance on a hand Balance the meterstick on a hand Record the results discuss and record your conclusions Repeat Steps 4 7 two more times placing the clay ball at a different location on the meterstick each time Record the results discuss and record your conclusions Part 2 Student Pairs Design and cut an unusual shape from the posterboard square Use as much of the posterboard as possible for the shape Mark an X on the shape where you think the center of gravity is located Tie one end of the string to the washer and make a loop with the other end Loosely attach the shape to a bulletin board with the push pin Place the loop of the string over the push pin with the washer hanging straight down Draw a straight line on the posterboard along the string Repeat Steps 4 6 for each side of the shape Make a dot at the point where all the lines cross Place the shape on the top of the pencil eraser at the dot and try to balance it Draw a picture of your unusual shape on the back of the activity sheet and label the center of gravity Record your observations and conclusions under the drawing Range of Results Students may initially find it challenging to balance the pencil on their index

  • Judi's Activity Page
    Involve students in a discussion about mobiles If possible have examples or pictures of mobiles available for them to observe Invite students to share their observations Encourage them to apply what they know about the center of gravity as they explain their ideas about how a mobile is constructed Challenge student groups to use what they know about the center of gravity to construct a mobile with six unusual shapes three straws and thread Procedure Each group member cuts out at least one unusual shape from the construction paper If there are less than six students in the group decide which shapes should be duplicated to give a total of six shapes Discuss and decide how the shapes and straws are to be arranged on the mobile Draw a picture of the arrangement Construct the mobile using the materials provided Make any necessary modifications to balance your mobile Write a description of and explain any changes made to your mobile design Range of Results Student groups may select to attach the unusual shapes to the mobile vertically or horizontally Students may also choose to tape the thread to the straws or pull it through the straws Modifications to the mobiles
