When you move the switch of a flashlight to "on," the light goes on. When you move the switch of a flashlight to "off," the light goes off. How does this happen?
A. When the switch is moved to the "on" position, it opens the circuit, and electricity flows through the flashlight bulb.
B. The wire in the flashlight is considered an insulator, and when the insulator is "on", you will have a closed circuit, lighting the bulb.
C. The terminals of the flashlight are the battery and the bulb. When these are connected, the bulb will light.
D. The switch in the "on" position closes the circuit, and the electricity flows through the flashlight bulb.

Create a double bubble map (or venn diagram) to explain how magnets and electromagnets are similar and different. Give two differences (on each side) as well as two similarities.
Differences:
Electromagnet- temporary; strength can be adjusted; can be switched on and off; uses electricity; poles can be switched; they are man-made
Magnet- permanent; naturally on Earth; can't be turned off; can't adjust the strength
Similarities: create a magnetic field; north and south pole; can be man-made; both attract magnetic materials

Bonsai trees are tiny trees that are carefully shaped to look like full-grown trees. They are usually started by taking a living piece of a normal tree. The piece grows roots and is planted in a very small pot. The grower trims the roots to keep the plant from growing very quickly. The branches are cut into nice shapes. The leaves may be kept small by removing leaves that grow too large. The tree stays small because it does not have enough space, water, or nutrients to grow to a normal size.
Which statement is evidence that bonsai trees are small because of their environment, not because of the size of their parents?
A) Bonsai trees are grown from pieces of normal-sized trees.
B) Bonsai trees look like full-grown trees.
C) Bonsai tree leaves may be removed if they grow too large.
D) Bonsai tree branches are cut into nice shapes.
A) Bonsai trees are grown from pieces of normal-sized trees.
