Opposites Attract
When in Rome
100
What are the two systems in a plant?
The Shoot and Root System
100
What is mechanical energy?
Energy due to motion or position
100
What is an ecosystem?
Community of organisms interacting with each other and their environment
100
Do opposite ends of a magnet attract or repel each other?
Attract, since a magnet has a north and south pole and opposites attract!
100
What is energy?
Ability to do work
200
What are three different things that could affect plant growth?
Anything! (salt, soil, water, light, etc.)
200
What do the symbols V, I, R represent in a circuit?
Voltage, Current, Resistance
200
Why are oil spills bad for the environment?
affects birds and mammals, sits on the surface of oceans, animals get weighed down due to oil
200
What is magnetism?
Motion of electric charge resulting in attractive and repulsive forces
200
Work = ?
Force * Distance
300
How can we measure plant growth?
Height, Width, Number of Leaves, etc.
300
What is a circuit?
A closed path that allows electricity to flow from one point to another
300
What is climate change?
Change in average conditions in a region over a long period of time
300
How is the Earth similar to a magnet?
Earth has a north and south pole that acts similarly to a bar magnet since Earth has a magnetic field!
300
Name all 6 of the simple machines.
Wheel & Axle, Pulley, Screw, Lever, Inclined Plane, Wedge
400
What are three different things that we include in an Experimental Design Diagram?
Title, Hypothesis, IV, Levels of IV, DV, Control, Number of Trials, Constants
400
What type of energy conversion did we do when building our rollerbot? (which type of energy to which)
Conversion of electrical to mechanical energy
400
What is the greenhouse effect and how do humans affect it?
Trapping heat from sun to warm planet’s lower atmosphere. Human activities increase certain types of gases that trap the sunlight more effectively, contributing to the greenhouse effect
400
Name an application of electromagnetism.
Electric motors and generators, Headphones, MRI machines, magnetic locks, relays, communication systems
400
How can a pulley be used to lift heavy objects?
Pulleys change the direction or amount of force to help lift heavy objects
500
What is the main conversion in photosynthesis? (hint: it involves sugar!)
Carbon Dioxide + Water -> Oxygen + Glucose
500
How did we use a photodiode in our circuit?
We used a photodiode as a switch (turning the motor on when the light was on)
500
Name 3 effects of climate change.
500
What is the Lorentz force? (hint: this is what made your magnets spin last week!)
When electrons move in a magnetic field, they create a force known as the Lorentz force
500
If it takes 15 N of force to move a box 4 meters, how much work is done total?
15 N * 4 m = 60 N*m!
