Science Processes 1 / Science Processes 2

## Pre-requisite

Science Processes 1 (Science Processes 2)

## Course description

Science Processes 1 is the first science course offered to students at SRHS. Students begin the course with lab experiments; group activities and lectures illustrating the importance of the scientific method for all scientific inquiry and human progress. It is a hybrid section that blends the traditional freshmen science curricula of Earth and Physical Science into an integrated course that prepares students for laboratory science at the secondary and post-secondary levels. From there the course that blends lecture; hands-on lab experiments and the process approach to develop skills in observation and analysis; and to discover; demonstrate; illustrate; or test scientific principles or concepts. It is organized around the themes; processes and importance of the scientific method and process. Course topics include:

? Scientific method
? Lab skills and safety
? Properties and states of matter
? Earth?s interior and surface
? Weather and climate
? The solar system and universe
? Forces and motion
? Fluids; kinematics; power; and energy.

Science Processes 2
Prerequisites: Science processes 1

Science Processes 2 is a continuation of Science Processes 1. It is also an integrated science course that blends lecture; hands-on lab experiments and process approach to science. It is organized around the themes; processes and importance of the scientific method. Course topics include:

? Scientific method
? Lab skills and safety
? Properties and states of matter
? Earth?s interior and surface
? Weather and climate
? The solar system and universe
? Forces and motion
? Fluids; kinematics; power; and energy.

Chapter 12 - Forces and Motion
Investigating a Balloon Jet
Problem: How does a jet-powered device move?
Materials:
? 3 meter long string
? Drinking straw
? 4 long ballons
? Stopwatch
? Meter stick
? 2 chairs
Procedure:
1. Insert the string through the straw and tie each end of the string to the back of a separate chair. Pull the chairs apart until the string is tight and horizontal.
2. Blow up the balloon and then hold the balloon?s opening closed. In the data table; record the length of the balloon. Have a classmate attach the balloon lengthwise to the straw; using tape.
3. While continuing to hold the balloon?s opening closed; slide the balloon jet to the end of the string.
4. Release the balloon. Measure the time during which the balloon jet moves. Measure the distance that the balloon jet travels along the string. Record the distance and time values in the data table for 0 Nuts Used; Trial 1.
5. Repeat Steps 2 through 4 with a new balloon. Make sure to inflate the balloon to the same size as in Step 2. Record your results in the data table for 0 Nuts Used; Trial 2.
6. Repeat Steps 2 through 5 twice more with a new balloon. This time; tape two nuts to the balloon before releasing it. Record your results in the data table for 2 Nuts Used; Trials 1 and 2.
7. Calculate and record the average velocity for each trial. The average velocity is equal to the distance divided by the time.
Analyze and Conclude:
1. Use Newton?s 2nd and 3rd laws to explain the motion of the balloon jet.
2. How did adding mass (nuts) to the balloon jet affect its motion?
