Estimating Measurements

Estimating Measurements (liters)

​

Would you pour this over your head?!

Hopefully not, but if you did...about how much ice cold water would you have poured?

Kind of hard to tell for sure...

This bucket is not used to measure volume, but we can still estimate how much water is in there. How you ask?

We use liters to measure volume

• Liters is the 'base unit'

• When you have 10 liters, you can instead say you have a dekaliter

• If you have 1000 liters then you have a kiloliter

• If you only have a small amount, 1/1000 of a liter - then you have a milileter

Multiple Choice

Check you understanding: Which has more volume? A cup with a kiloliter of water or a cup with a milliliter of water?

• kiloliter

• milliliter

• whataliter?

Multiple Choice

Would you rather have a hectoliter of frosting or a centiliter of frosting? (assuming you can't get enough of frosting?)

• hectoliter

• centiliter

But, how much is a liter?

Let's look at some examples

Multiple Choice

Let's get back to the bucket...how many liters do you think are in this bucket?

• 10 L

• 25 L

• 55 L

Multiple Choice

• 100 mL

• 1 L

• 5 L

• 100 L

Multiple Choice

• 50 mL

• 50 L

• 1,500 L

• 200 mL

Multiple Choice

Open Ended

What drink do you hope this is filled with?

Multiple Choice

Estimate how much of your favorite drink is in this cooler.

• 1 L

• 5 L

• 20 L

• 200 L

Open Ended

Why would 1 L be a ridiculous answer for estimating the volume of this cooler? What would be another ridiculous answer?
