Kala wants to make a simple circuit with a battery, a lightbulb, and a switch. She connects the lightbulb to the switch with one wire, and to the battery with another wire, as shown below. To have the lightbulb turn on, Kala must do one last step before closing the switch. Which step below must she do?
Ⓐ Add a wire from the switch's unused electrical contact to the negative terminal of the battery.
Ⓑ Add a wire from the switch's unused electrical contact to its second electrical contact.
Ⓒ Add a wire from the switch's unused electrical contact to the positive terminal of the battery.
Ⓓ Add a wire from the switch's unused electrical contact to the electrical contact of the light bulb it does not yet touch.
A. Add a wire from the switch's unused electrical contact to the negative terminal of the battery.

Mass and weight are both physical properties of matter. Why can weight change depending on where an object is but mass will stay the same?
Weight is a result of gravity.
Mass is how much matter an object is made up of.

Jason is at the edge of the dock looking in the water. He sees a fish, but he knows that because of the way in which light travels, the fish appears to be closer than it actually is. What caused the change in the way the light was traveling?
Ⓐ Light frequently curves and bends as it travels.
Ⓑ When light strikes an object, it may be absorbed.
Ⓒ Light travels in a straight line, but it bends when moving from water to air.
Ⓓ Light travels in a straight line, but it reflects when moving from water to air.

Compare and contrast and experiment and investigation. 200 points for differences 200 points for similarities
Differences- Experiments must have control, variable, 3 trials
Similarities- both try to answer a question, gather information/data, can have constants, can be a test.

Lincoln is working with Mrs. Frizzle at Activity 2. He created a fourth bottle with 25 mL of water. He noticed that this bottle produces a pitch that is lower than the other bottle with 50 mL of water. Which of the statements BEST explains why the lower the amount of water in the bottle, the lower the pitch is?
Ⓐ. When there is less water, the air vibrates faster, producing a low pitch.
Ⓑ. When there is less water, the air vibrates more slowly, producing a low pitch.
Ⓒ. When there is less water, the water vibrates faster, producing a low pitch.
Ⓓ. When there is less water, the water vibrates more slowly, producing a low pitch.
A. When there is less water, the air vibrates faster, producing a low pitch.

Nancy observes how a paintbrush appears in a glass of water. Despite the paintbrush’s appearance, it is neither bent nor broken. Why does this happen?
Ⓐ Light bends when it passes between different materials, such as air and water.
Ⓑ Light may reflect off of smooth surfaces, such as glass or water.
Ⓒ More light is absorbed by a pencil than by air or water.
Ⓓ Light travels through glass or water in a zigzag path.
Ⓐ Light bends when it passes between different materials, such as air and water.
