https://www.youtube.com/watch?v=WuaxXcgX6Rc

Sections 3: Complete your Mythbusters worksheet.

Also, create a measurement system to re-"measure" the item you measured last night but it cannot be based on ANY formal measurement system. Bring your measurement tool and item into class tomorrow.

Section 6: Your first assignment is to find an object in your house that you can measure in three different ways. What the heck does that mean??? Well, think of yourself, for example. You can tell someone how tall you are, how heavy you are, how much space you take up. Even though all of these things are descriptive of you, they would all be measured in very different ways.

Once you've chosen your object, write in your binder the following information:

What is it?
Why did you choose it?
1st measurement and what instrument/method you used to obtain it.
2nd measurement and what instrument/method you used to obtain it.
3rd measurement and what instrument/method you used to obtain it.

**Make sure to include units and be as accurate as possible!

Monday, September 9

Sections 1&2: Take two of the items you measured last night and "measure" them again, but this time you are not allowed to use any formal measurement system - you must create your own!! If you cannot bring in your created measurement tool, make sure to take a picture on your phone while you're measuring! Think outside the box!!

Section 3 & 7: Please bring in the item you measured last night, or another item that can be easily measured. Bringing in your measured item from last night's homework is ideal!
Also, watch this video:
