Today in **science**, the students had time to work on their Calculating Speed lab sheet from yesterday. They were given the following post-lab questions to answer on the back of their lab sheet:

1.Which runner in your group was the fastest? What was his/her **average** speed?

2.Did the runners maintain consistent speeds, or were their speeds different at the various distances? Explain.

3.What is the relationship between speed, distance, and time? Use **C-E-R** and evidence from the lab in your response.

**Warm-up:** Use the graph to answer the following questions:

1.Why would Charlie’s average speed for the entire race be slower than his typical average speed?

2.What do you think might have happened?

**Homework:** The Calculating Speed lab (including the post-lab questions) is due tomorrow; complete the Unit 5, Lesson 2 reading and Cornell notes, due next Tuesday, 3/3.

In **STEM**, the students had time to finish the roller coaster interactive they started working on yesterday. **Warm-up:** From yesterday’s roller coaster project intro.:

1.What’s the maximum height?

2.What are the maximum length and width?

3.What will you use as the “car”?
