Document: Friction Abstract: Friction is a Force that always pushes against an object when it touches another object” “When 2 things are in contact with each other, there will be friction acting between them”

Document: Speed Investigation Activity Abstract: Student investigates speed as an important variable regarding force of an impact. Students roll a car down a ramp and into a block of wood. The distance the car travels, the time until impact and the distance the block moves are recorded. The speed of the car is calculated. Students are asked to design and perform...

Document: Balloon Vehicle Hands-on Activity1 (1) Abstract: Make a vehicle using the materials provided. This vehicle should do the following: Use wind power from the balloon to supply a force to move the vehicle travel in a straight line.

Document: Energy and Electric Field Activity-1 Abstract: Use this applet for a couple of minutes. Add multiple charges using the “add” button. To adjust the sign or mass of a charge to be added, you must first click on the “Properties” button, make your change and click “done”. The next charge you add will reflect your change. For some reason...

Document: Teacher Materials – Unit 7 Abstract: Use this applet for a couple of minutes. Add multiple charges using the “add” button. To adjust the sign or mass of a charge to be added, you must first click on the “Properties” button, make your change and click “done”. The next charge you add will reflect your change. For some reason the...

Document: Roller Coaster Physics Investigation Performance Task Abstract: The purpose of this simulation lab is to strengthen your understanding of energy conservation in real-world applications.  You will use a skateboarder and his park to represent the roller coaster and its track.  You will observe many other physics concepts at work as well.

Document: Newtonian Vehicle Abstract: You will design, build, and test a self-propelling vehicle that can travel a minimum distance of one meter. When designing the vehicle, sketch a diagram showing how it will be propelled (balloon, rubber band, mousetrap, etc.) and the forces that act on the vehicle when it is stationary and moving. After building and testing the vehicle, write...

Document: Collisions Abstract: Welcome to this science exercise. We hope that you will find it interesting and worthwhile. Carefully read through these directions and the directions on the next page before you begin to work.

Document: Sound Wave Lab Abstract: Cut a piece of string about half a meter long and tie it to the neck of a metal hanger. Wrap each end of the string around a finger on each hand about the same amount. Swing the hanger so that it strikes a desk or table. Observe and describe the sound as you hear it through the...

Documents: Science Unit 3 (Revised)-5 Abstract: Unit three is Exploring Change, specifically bonds, energy, and reactions.  The change to be investigated will include indicators of chemical reactions as they relate to chemical bonding and energy changes. Chapters 7 and 8 cover ionic and covalent bonding respectively, while chapters 9 and 19 are the introduction to stoichiometry, chemical reactions. Again, a review...
