4. a. If you went on the field trip with Mr. Billingsley:
You need to collect some data in the hallway. Go with a partner to collect two times for walking up the stairs and two times for "walking fast" up the stairs. When you come back with data you may finish your calculations.

4. b. If you DID NOT go on the field trip with Mr. Billingsley:
You must answer the Check for Understanding questions on the worksheet.

5. EVERYONE: for homework tonight you have to read pages 89 & 90 in your blue Physics text and respond to the following prompt. Complete this on the back of your worksheet from today:

You are a fitness trainer and one of you clients wonders why it matters how fast he lifts weights. He says, "you want me to start by lifting a barbell in 10 seconds, and then 9 seconds, then 8 seconds, etc. until I do it in 1 second. Why can't I just lift it at my own pace?" Explain to him why it matters how fast he lifts the weights? Use the words work, joules, seconds, power, watts, and horsepower. Write at least four sentences.

6. If you have time, try this lab. You will need someone to measure how far you move when you do a push-up, but you can easily compare to see who is more powerful.
