What is the volume of the ring on page 2?

4mL

100
Using the periodic table on page 1, how many neutrons are in the most abundant aluminum (Al) atom?

14 neutrons

100

Is there only one correct frame of refrence?

No! Frame of reference is a relative term! An object's motion looks different depending on how you look at it.

100

Name the moon phase on page 9.

3rd quarter moon

100

Identify the independent variable in the experimental question: 

What is the effect of the amount of force applied on the displacement of a spring?

Amount of force

200
Using the chart on page 3, at what temperature is the solubility of CaCl2 the same as NaNO3?  (reasonably estimate)

about 25 degrees

200

How many protons, neutrons, and electrons does calcium have?

Protons = 20

Neutrons = 20

Electrons = 20

200

Calculate the net force of the object on page 8.

700N to the right/east

200

What tide occurs during the moon phase on page 11?

Neap tide!
200

What is the Octet Rule?

An atom is stable if it has 8 valence electrons on the outermost shell!

300

What is the volume of the swimmer on page 4?

8mL

300

How many valence electrons does chlorine have?

7 valence electrons

300

Calculate the net force of the object on page 7.

15N to the right

300

What is responsible for the change in tides each day?

The moon!

300

Why does the moon orbit the Earth? (HINT: Same reason why planets orbit the sun!)

The Earth's gravitational pull on the moon

400

All three boxes on page 5 have the same mass. What is different about them?

Their volumes and their densities

400

Why would potassium (K) easily lose one electron but not two?

If potassium loses 1 electron, then it will become stable since the next shell has 8 valence electrons. It would not lose two because then it would be unstable with 7 valence electrons. 

400

What direction will the marble go in if a rightward force is applied to the cart? You must be able to explain!

Possible answer: The marble will go to the left because inertia resists a change in motion!

400

Looking at the Sun-Earth-Moon diagrams on page 12, which one (A, B, C, or D) represents a solar eclipse?

A

400

Identify the dependent variable in the experimental question: 

What is the effect of the amount of force applied on the displacement of a spring?

Displacement

500

Using the solubility chart on page 3, at what temperature is the solubility of KCL the same as KNO3?

About 22-23 degrees.

500

Identify the element on page 6.

The element is copper (Cu)!
500
Name the two forces that act on a gymnast who has fully descended on a trampoline, about to bounce up?

Spring force and gravitational force!

500

Looking at the Sun-Earth-Moon diagrams on page 12, which one (A, B, C, or D) represents a lunar eclipse?

C

500

Looking at the chart on page 13, when could we expect the next high tide? Explain how you know this!

12:00am because the tides follow a cyclical pattern
