Task 2 Units of Measurement
During your study of Chemistry you learned to make good OBSERVATIONS based on physical properties of substances. During your study of Physics you will need to take accurate measurements and manipulate them. This is about relationships between variables. All scientists learn to manipulate data so as to better understand the relationships between variables.
Heading: Units of Measurement
1. SI Base Units.
Use Science and Inquiry 1 as a reference. Set up a table to learn the SI Base Units of measurement, page 32 Understanding measurement basics 2.1
These are units that may be measured directly.
2. Common SI Derived Units
These are units that are the result of measuring and manipulating more than one variable.
Use the back of your white Science Practical Book to set up a table of derived units to learn. You will only learn those units used in your Energy and Forces course.
3. Metric prefixes
Science and Inquiry 1 Do Checkpoint 4 page 34
4. Understanding measurement basics 2.1

Discussion Questions
Discussion Questions
- Where does the potential energy in the lever arm come from?
- Where is there potential energy throughout the loading, cocking, and releasing of the trebuchet? Where is there kinetic energy?
- What evidence is there that energy is conserved?
