1. Engage
2. Explore
3. Explain
4. Extend
5. Evaluate

(1^st E) What do you think?

Rank ramps by a marble’s speed at the bottom. Submit prediction on energizingphysics.com.

Let’s see what we think.

v=0 m/s

A

C

B

Speed Here

(2^nd E) Let’s Investigate

1. Collect 4 times for each ramp.
2. Measure at least 5 ramps.
3. Submit each data point on energizingphysics.com

100 cm

(3^rd E) Analyze Data

What does the data show?

​

Which ramp variables affect the speed of the marble?

​

Was your prediction rationale correct?

Looking at your data:

(2nd E #2) What if height is the same?

• Buddy up with one other person.
• Person 1: Timer
• Person 2: Online Data Entry
• All groups measure the same marble roll (for 10 trials)
• Submit each time on energizingphysics.com [DATA FORM 2]
• Let’s Look at the Data.

The Data from the fastest ramps.

(4^th E) Try This #1

Which choice correctly ranks the ramps by marble speed at the bottom?

1. C>D>A>B
2. C=D>A=B
3. A=B=C=D
4. B>A>D>C
