  1. How High Can You Jump?

  2. Gravity • The force of attraction between two objects that have mass.

  3. Mass • The amount of matter in an object.

  4. Weight • The gravitational force exerted on an object.

  5. Purpose • To discover how high you would be able to jump on other planets.

  6. Hypothesis Questions to answer: • On what location listed do you think you would be able to jump the highest? • On what location listed do you think you would be able to jump the lowest? Your response • I think I will jump the highest on …. • I think I will jump the lowest on…

  7. Materials • Meter Stick • Calculator

  8. Procedure • Ask a student to jump as high as he/she can. This is an example of how high one person can jump on one planet (the Earth). • Give one student a meter stick to hold vertically, touching the floor. Have another student kneel so that he/she can see the meter stick in order to measure the height of the student’s jump.

  9. Data

  10. Lets Analyze Your Data • The largest number indicates the highest jump meaning there was LESS gravity. • Identify the location in which you jumped the highest. Put a star next to it and write “least amount of gravity” • The smallest number indicates the lowest jump meaning there was MORE gravity. • Identify the location in which you jumped the lowest. Put a star next to it and write “most amount of gravity”

  11. Conclusion • Restate purpose. • “The purpose of this lab was to….” • Was your hypothesis correct or not? Explain using evidence from data. • “My hypothesis was …..” “I was correct/incorrect because….” • What were the errors that could have occurred? • “My calculations could have been off due to…” • What two factors affect your gravitational force? Explain. • “The two factors that affect gravitational force are … because …” • Looking at your data, what locations have the greatest gravitational force? Least gravitational force? Explain. • “The greatest gravitational force was located at … because …” “The least gravitational force was located at … because … “ • After completing this activity and seeing that your height of your jump would change dependent on your location, would your weight change? Explain. • “My weight would/would not change because...” • Would your mass change depending on your location? Explain. • “My mass would/would not change because…”
