Miley went on 15 kilometer bike ride. How many meters did she

ride?

Miley went on 15 kilometer bike ride. How many meters did she ride? Not enough to find her

dignity!

KILO= 1,000

So she went on a 15 thousand meter ride

15km=15,000m

When observations deal with amounts or numbers they are

called QUANTITATIVE OBSERVATIONS

QUANTITY=NUMBER

What is an INDEPENDENT VARIABLE?

When multiplying or dividing measurements, the answer has the

same number of significant figures as the measurement with the

______________ significant figures.

When multiplying or dividing measurements, the answer has the

Will an object with a volume of 100 cubic centimeters and a mass of 50 grams float or sink in pure

water? What is its density? SHOW YOUR WORK

Will an object with a volume of 100 cubic centimeters and a mass of 50 grams float or sink in pure water? What is its

density? SHOW YOUR WORKOk, there are a couple of things that you need to know here…

1)The density of pure water is 1g/ml

2)If the density of the item is GREATER than the other stuff, it is a SINKER! If the density of the item is less than the density of the other

stuff… we have a FLOATER!

Back to our problem! D= M/V=50g/100cc= .5g/ml

We have……. A FLOATER!

people allergic to grass. What is the dependent variable?

What is the independent variable?

What are you testing? = independent variable =A new drug

• How will you test it? What d d d data will you collect/count?= dependent variable= count the sneezes (how well it works)

Cool links to find out more are below… click em’ I double dog dare you!

Use you paper study guides! They are a LOT more complete than this power point! If you can answer ALL the

questions on your study guide then you should be ready for the test. If you

can’t….. You should expect to do not so well on your test. Study session on the morning of the test. Hope to see you

there!
