Welcome
Congratulations and welcome to the Integrated I Science Class! We will be learning Chemistry, Physics, Astronomy and Earth Science. So, we have a lot to do and class time is precious. To prepare for class, please review the following lessons and print out the pages where it directs you to do so. Don’t forget to check out Mr.Heinze’s staff eboard. Please read the note labeled requirements for Integrated I science.Have a safe and happy summer. Good luck and see you soon.
Metric Review
The metric system or SI system is based on the number 10. The one’s or base unit, is designated as “O “ It contains the base unit for each of the metric units. The three base units are meter (m) for length, grams (g) for mass, and liter (L) for volume. These can also be called the ones, since they are represented by one single letter. Please review your definitions of volume, mass and length. To represent larger numbers or smaller numbers, we add prefixes to the base (ones) units. The following is a list of the main prefixes and the ones units in order.
Prefix Value Example
- kilo (k) - 1000 75km 75 kilometers
- hecto (h ) - 100 20hg 20 hectograms
- Deka (D) - 10 67DL 67 dekaLiters
- Ones 1 - Base unit (meter, liter, gram) 180g 180 grams
- deci (d) - .1 5dL 4 deciLiters
- centi (c) - .01 100cm 100 centimeters
- milli (m) - .001 53mm 53 millimeters
There are many other prefixes. Larger prefixes include mega (millions) and giga (trillions) and some smaller prefixes are nano and pica. The prefixes that you will be responsible for, are the prefixes found above in the list. This list is easily remembered by the phrase "KidsHave Dropped Over Dead Converting Metrics” or “King Henry Drinks Only Delicious Chocolate Milk". The great thing about the metric system is that it makes converting easy - all you have to do is move the decimal point.To make a conversion, simply recall the saying and write down the first letter of each prefix. See the list below:
k
h
D
O
d
c
m
Now simply count with the unit your starting at,to the unit you want to convert to. You will move the decimal point at your starting value, the number of moves you just counted. If you moved up the list then move the decimal point to the left. If you moved down the list then move the decimal point to the right.
Example. Convert 173 cm to ______m. Start counting at the c on the list moving up the list to the One’s place. This is where the meter, liter and gram are. You should have counted 2 places. Since we moved up the list we will move the decimal to the left 2 places. From 173.cm to 1.73m.Please print out this page in black and white and make the conversions.

How do I read a ruler?
Did you know?
A ruler used to be called a rule, and rulers would be rules. Today, the more commonly found term is ruler.
Metric Rulers
Metric rulers are easy to read. They deal with centimeters and millimeters only. You won’t have to worry about fractions.Take a look at the following Metric Ruler.
The larger lines with numbers are centimeters, and the smallest lines are millimeters. Since millimeters are 1/10th of a centimeter, if you measure 7 marks after a centimeter, it is 1.7 centimeters long. There are 100 centimeters to one meter. Just like 1 cent makes 1/100 of a dollar. It takes 100 cents to make 1 dollar.
English Rulers
English rulers, are more difficult to read. Mostly because they deal with fractions, which are a bit more difficult to learn.Take a look at the following English Rulers.
A ruler marked in 8ths. Every mark is 1/8th of an inch.
A ruler marked in 16ths. Every mark is 1/16th of an inch.
The red lines on these rulers are marked at 1/2, and 1. /
The next smallest marks on a ruler are 1/4ths.
The red marks on these rulers are at 1/4, 1/2, 3/4, and 1. (1/2 is the same as 2/4) /
The next smallest marks on a ruler are 1/8ths.
The red marks on these rulers are at 1/8, 1/4, 3/8, 1/2, 5/8, 3/4, 7/8, and 1. /
The next smallest mark, if there are any, are 1/16ths.
The red marks on this ruler are at 1/16, 1/8, 3/16, 1/4, 5/16, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, 3/4, 13/16, 7/8, 15/16, and 1. /
When writing down a distance on a ruler, write the whole inch, followed by a space, then the fraction of an inch. This may take some practice. Please Print out the next page and write the answers to the measurements.

Finally go to the following URL and Play the Ruler game.
Read the instructions. Please click set the game for “timer on” and “intervals Quarters”. Play until you reach 300 points. Then print the page for proof that you reached the goal.
Remember
Please bring the 3 printed pages with you to school on the first school day. See you soon.
