If you finish your test corrections early:

• Work on your science fair project (p. 2-3 due tomorrow)

• Work more on your research plan for the science fair, or start brainstorming questions

• You can skip the project journal for now—raise your hand to get your testable question checked off by Mr. S.

Entering the Classroom

• Pick up a Measurement packet at the door.

• Get out your binder and a sharp pencil.• Write your name at the top of p. 1 of your

packet• Look over the cheat sheet on p. 2• Open your packet to p. 3.

Measurement Key Question:• Why should the U.S. change to the metric

system? Or not?

Objectives• C: Define: Mass, weight, perimeter, volume,

temperature, length• L: Write sentences and definitions for each

word

Standards:I.I.I.2. Use models to explain the relationships between variables being investigated.I.I.III.2. Use mathematical expressions to represent data and observations collected in scientific investigations.

Mass

• Mass is how much material something is made of

373.35 g

Weight

• Weight is the force that gravity pulls on the mass. Weight is related to mass.

1 N = 0.2 pounds

Length

• Length is a distance.

Perimeter

• Perimeter is the distance around something.

Volume

• Volume is the amount of space something takes up.

Temperature

• Temperature is the hotness or coldness of something.

1. Finish writing sentences and drawing pictures for each word.2. Raise you hand to get your vocab journal graded

1. Take out your Science Fair Packet and get a grade for having p 2-3 complete (set the packet on your desk, open to p. 3)

2. If you’re finished with p. 2-3, brainstorm a question that can be tested.3. Raise your hand to get your question approved by Mr. Switzer.

(Note: If you choose not to complete your science fair work, you can make up some of the points by writing a research paper).

Entering the Classroom

• Pick up an Exit Ticket paper at the door

• Get out your binder and a sharp pencil• Get out the Measurement packet• Open to p. 3

*(If you were absent when we picked up the measurement packet, please raise your hand immediately, and ask Mr. Switzer for one.)

**(If you lost your packet, take out a blank sheet of paper to copy the notes).

Flashback!

1. What is the definition for “volume”?

2. What is the definition for “perimeter”?

When you’re finished, turn to p. 4 in your packet and read about the Metric System.

Measurement Key Question:• Why should the U.S. change to the metric

system? Or not?

The Mars Climate Orbiter (MCO)

The Problem: In one of the all time great engineering gaffs, NASA’s partner, Lockheed Martin, used Imperial units, not the metric units used by NASA. The probe eventually hit the Martian atmosphere at the wrong angle and burned up.

Objectives• C: Explain and estimate metric units for

length, mass, volume, temperature, and time• L: Write complete sentences to answer

questions on the exit ticket.

Standards:I.I.I.2. Use models to explain the relationships between variables being investigated.I.I.III.2. Use mathematical expressions to represent data and observations collected in scientific investigations.
