I apologize for not having this posted sooner. I will normally have homework posted by Tuesday afternoon.

Thank you for your patience.

Homework Week 2, Due Sept 1

>Read module 1 if you haven't already read it.

>Do Study Guide on p. 24

>Read over the experiments in module 1 if you haven't read them.

>Copy the following chart into the front of your notebook or tape it into your notebook:

__Conversion Factors for Physical Science __

1 inch = 2.54 cm

1 mile = 1.609 km

1 cup = 236.588 mL

1 quart = .946 L

1 pound = 453.592 g

2.2046 pounds = 1 kg

If you are having difficulty understanding conversion using the factor-label method, there is a step by step explanation below as well as a couple of practice problems. Let me know if this doesn't help you understand.

Factor-Label Method Step-by- Step

Convert 14 pounds into grams.

1. What do you know? Put that over 1.

__14 lbs.__

1

2. What do you need to know? Multipy that by its conversion factor. (See chart above.)

__14 lbs. __ x __453.592__g =

1 1 lb.

3. Now, do the math...

__14 lbs. __ x __453.592 grams__ = 6350.288 grams

1 1 lb.

Let's Try another one...

I need 235 mL of water for a recipe. What is that in cups?

1. What do I know? Put it over 1.

__235 ml __

1

2. What do you need to know? Multiply what you know by that.

__235 ml __ x ____cups =

1

3. Now, put in the conversion factor from the chart above.

__235 mL __ x ____1______cups__ = (make sure you divide this time)

1 236.6 mL

4. Do the math...

__235 mL __ x ____1______cup__ = .993 cups or about 1 cup

1 236.588 mL
