In the following web page you will find one lesson I use to start the school year. Also included are links to other lesson plans you may find useful.


Materials: Meter stick, scale, graduated cylinders, pennies, fishing weights, paper clips, paper cup, paper, wrist watch, washers, gram weights, water, pencil, worksheet.
Lesson: If these are the 7th graders that were 6th graders last year you can review the prefixes to the metric system and have them begin the measurement with the meter stick. If they are the 6th grade you will need to explain the metric system, and the meaning of the prefixes.
Worksheet: This worksheet was designed by the previous science teacher Joan C.
Mass
Weight in the metric
system is measure by grams or kilograms. One - thousand grams are
equal to one kilogram. Twenty eight grams is equal to one ounce and
2.2 pounds are equal to one kilogram.
You are to estimate how
much the following things weigh. After you make your estimation
then weigh the item on your balance and check your estimation. For
each item I want you to estimate first and then weigh the item. By
the end of this exercise, you should be getting better at making estimations
using the metric system.
| Item | Estimation (g) | Actual Weight (g) |
| pencil | g | g |
| paper clip | g | g |
| paper cup | g | g |
| folded piece of paper | g | g |
| wrist watch | g | g |
| metric ruler | g | g |
| fishing weight | g | g |
| washer | g | g |
Length
In the metric system, length is measured by meters.
A millimeter is 1/1000 of a meter. In other words 1000 millimeters
equal 1 meter. A centimeter is 1/100 meters or 100 centimeters is
equal to 1 meter. A kilometer is 1000 meters.
As you did for weights, first make an estimate
then measure.
Using centimeters:
| Item | Estimation ( cm) | Actual Length (cm) |
| The height of a desk | cm | cm |
| The width of a desk | cm | cm |
| The length of your left leg | cm | cm |
| The length of you right arm | cm | cm |
| The distance between you tip of your nose and your chin | cm | cm |
| Item | Estimation (M) | Actual Length (M) |
| The distance along the floor form the door to the windows. | m | m |
| The distance along the floor from one chalkboard to the other. | m | m |
| The length of one chalkboard. | m | m |
| The height of a chalk board. | m | m |
| Trials | Estimated Amount (ml) | Actual Amount (ml) |
| Trial #1 | ml | ml |
| Trial #2 | ml | ml |
| Trial#3 | ml | ml |
| Trial#4 | ml | ml |
| Trial#5 | ml | ml |
| Trial#6 | ml | ml |
