1. Question of the Day What units do you use to measure height? What units do you use to measure weight?

2. Basic Measuring

3. Making Measurements When making measurements, it is necessary to include both a NUMBER and a UNIT For example, when measuring a piece of wood, you would say “the piece of wood is 5 feet” 5 is the number, feet is the unit

4. Measuring in Science Science uses the metric system of measurement. This is used all across the world. This is different from the system we generally use in America.

5. Why is it different in science? Science uses the metric system for multiple reasons: 1.So scientists from all around the world can work together 2.So scientists can repeat their experiments 3.So everyone speaks the same language

6. How do we measure length? In science, length is measured by meters – ex. millimeters, centimeters, meters Length is measured using a metric ruler

7. How do we measure mass? Mass is a measure of how much resistance something has Mass is measured using grams We will measure mass using a triple-beam balance

8. How to record data We will record data using tables and line graphs With all tables, make sure to include both a NUMBER and UNITS (ex. 0.4g or 0.4 grams)

9. Making a line graph Line graphs contain two variables: an INDEPENDENT variable and a DEPENDENT variable The DEPENDENT changes because of the INDEPENDENT For example, Weight changes because of age, not the other way around -So INDEPENDENT = age DEPENDENT = weight

10. TITLE DEPENDENT VARIABLE INDEPENDENT VARIABLE
