Simple Machines
This simple machine uses a rope and wheel to raise an object. When you pull down on the rope, the object is lifted.
What is a pulley?
The scientific term for stored energy (like the payload of a catapult being pulled back before launch)
What is potential energy?
This tool works best when angled in order to clear a path instead of being attached straight ahead
What is a snow plow?
At Halloween, we constructed these from Legos to hold a set of toothy jaws in place
What are monsters?
This is the first step in the engineering design process
What is: Define the problem
(Ask "What is the problem that needs to be solved?")
This simple machine is composed of a lever with an inclined plane wrapped around it to form a spiral.
What is a screw?
An object at rest remains at rest until this is applied to it
What is a force?
When you draw an imaginary line down the center of a snowflake and both sides match exactly
What is symmetry?
We made wrecking balls out of this vegetable
What is a pumpkin?
In the "Taco Party" video, this was the first prototype to solve the problem of feeding a group of friends coming over for dinner that, when tested, everyone decided was gross
What is peanut butter and jelly on corn tortillas?
With a minimal amount of force, simple machines make this easier
What is work?
An object in motion has this type of energy
What is kinetic energy?
This ingredient, when added to a bag containing a cut apple, kept it from growing mold
*Bonus: This ingredient was also added*
Salt
*Bonus: Baking soda (which is also a type of salt)*
If you ever drop something valuable down this opening, you should be able to build a tool to retrieve it
True or False? The Engineering Design Process ends once you make a working model
False
A knife, doorstop, or axe blade is an example of this simple machine
What is a wedge?
True or false: Pushing, pulling and wind blowing are examples of forces
True
This solvent (testing liquid) was used to draw hidden color pigments out of fall leaves
What is rubbing alcohol?
After a chromatography test, it was discovered these colors make up black ink
What are blue, green, and red?
You should do this after brainstorming solutions but before building a prototype
This simple machine is also known as a ramp
What is an inclined plane?
The potential energy of a bow and arrow when the arrow is pulled back is stored in this part of the bow
What is the string?
These are remnants of life that existed hundreds, thousands, or millions of years ago preserved deep in the earth
What are fossils?
Our Frankenstein visitor's name
Who is Steve?
The step in the EDP where you come up with as many ideas as possible to solve the problem before building a prototype
What is Think or Brainstorm?
