Why do you run experiments three times?
Select one challenge that you and your group completed in this unit. What steps did you take to build your vehicle?
Answers will vary
What is the job of the tires on your vehicle?
To grip the surface and move the vehicle
A measure of how fast something is moving
Speed
A measurement of how heavy something is
Weight
What provides the force in the falling weight system?
Gravity (the washers being pulled down)
What best describes the one thing that changes in an experiment?
A variable
Explain why most technical drawings show more than one view
It is easier to build when you can see more than one view
Information gathered during an experiment
Data
The ability to do work or make something happen
Energy
Name a variable we changed in an experiment
Number of washers, number of rubberband winds, number of blocks
If I wanted to create the greatest air resistance, would I have my sail flat or curved?
Flat
Describe the difference between potential energy and kinectic energy
Potential energy is stored energy or energy that is ready to be released. Kinectic energy is energy in motion
A detailed plan or drawing that shows how something is designed
Blueprint or Technical Drawing
Three laws that describehow objects move in relation to the forces acting on them
Newtons 3 Laws of Motion
To make my vehicle move faster I need to make these three changes
Decrease load, increase force, wind the rubber band more times
To make my vehicle move slower, I need to make these three changes
Increase load, decrease force, and wind the rubber band fewer times
Explain the difference between a sketch and a technical drawing
A sketch is a quick, non- detailed drawing. A technical drawing has details, labels, and has more than one view
An element in an experiment that can be changed
Variable
Force that resists movement between two objects that are touching
Friction
Where was the energy stored in both the axle- driven and propeller driven vehicles?
The Rubberband
Explain how a propeller moves a vehicle
The blades of the propeller push the air backwards like a fan; the force of the air pushes the vehicle forward
What does it mean to find the median of your data?
