In Part Two, you will apply the engineering design process to design your own skate park ramp.
Instructions:
1. Select the Playground Simulation at the bottom of the simulation window.
2. Once the Playground Simulation loads, select all of the following options located on the right-hand side of your screen:
• Pie Chart
• Bar Graph
• Grid
• Speed
• Leave mass on the center setting
• Set friction to none
3. Complete the Hypothesis, Design, Testing, and Conclusion sections below.
Hypothesis:
In this section, include the if/then statement for your lab. This statement reflects your predicted outcome for the investigation. With the grid selection on, make a hypothesis about how the starting height of the skater will affect the energy needed to successfully complete your skate park playground ramp design.
If my skater begins at a height of 4.8 meters, then the skater will have enough total energy to successfully complete the skate park ramp from start to finish. (Fill in the blank with a height between 0 and 10 meters.)
Design:
You will test three different skate park ramp designs that meet the following criteria:
● The skate park playground ramp must include at least one loop.
● The skate park playground ramp must rest on the ground.
● The skater must complete a successful run from one side of the ramp to the other without falling off the ramp.
To begin designing your skate park ramp, use the ramp pieces located on the bottom left of the Playground Simulation. Drag and drop sections of ramp onto the screen. You may also select and drag the red dots to extend, move, and/or connect each individual section.
Get your ramp design working well with no friction. Then, increase the friction and explore what happens. Observe how increasing friction changes the height the skater can achieve.
How did the ramp perform? Was the skater able to complete the ramp successfully? You may open a new tab for each ramp design. You will choose one ramp design for further testing.
Record your observations in the data chart below for all three ramps. To insert an image into the chart, go to the bottom right corner of the simulation screen. You will find the screenshot option in the 3-line main menu icon. Insert the image into the chart and resize. Or, you can describe your ramp in words. Be sure to include the height from which the skater begins in your description.
