1 WARM UP 3-4 mins: exploring energy with Phet Skate Park. Directions: 1) QUIETLY get a computer, and, with your partner,-search (Google) for: Phet Skate Park: Phet Skate Park 2) Click on the first link and when you get a pop-up, Click on the button to get started. Ignore any error messages. 3) For 3-4 minutes--explore the simulation with your partner and complete the following checklist: Move the blue dots on the track and run the skater. Try out different locations. Try different skaters. Try the different energy graphs. Add/take away friction on the track. Exploring Potential, Kinetic energy and Conservation of : Part 1: 1) Reset the simulation. Then make your screen look like the picture by: Choosing one of the skaters. Click to open the bar graph Dragging the graph closer to the track. 2) As you watch the simulation, fill in the data table below: ( for increases, for decreases, SAME for stays the same) Skater s Movement Traveling down the hill Traveling up the hill Potential Kinetic Total (Mechanical ) 3) Discuss the patterns you see in the data table above. Then, add the words increases, decreases or stays the same to complete the observation statements: As an object moves down the track, the kinetic energy and the potential energy. When the object moves up the track the kinetic energy and the potential energy. 4) Look at your data table and focus on the Total energy column. Write a statement or two about the total energy (mechanical energy) of the object moving up and down the track and how it relates to KE and PE:
2 PART 2: exploring FRICTION with Phet Skate Park. 1. Reset the simulation. a) Open the bar graph again b) Click. c) Move the slider to change the friction Discuss the changes in the bar graph as the skater moves up and down on the track. 2. 2) As you watch the simulation, fill in the data table below: ( for increases, for decreases, SAME for stays the same) Skater s Movement Traveling down the hill Traveling up the hill Potential Kinetic Total (Mechanical ) THERMAL energy Discuss any patterns you see in the data table. 3. Change the skater and repeat this part of the activity. complete the following statements: (increases, decreases, stays the same) - As an object moves down the track, the kinetic energy and the potential energy. The total energy. - As the skater moves with increased FRICTION, the kinetic energy and potential energy of the skater both, the thermal energy and the total energy.. 4. Write a general trend statement to summarize what changed and what stayed the same when FRICTION was added to the skate park. 5. Which situation, with friction or without friction, is more similar to your everyday experience on a skateboard or bicycle? Why?
