What is the volume of the ring on page 2?
4mL
14 neutrons
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.
Name the moon phase on page 9.
3rd quarter moon
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
about 25 degrees
How many protons, neutrons, and electrons does calcium have?
Protons = 20
Neutrons = 20
Electrons = 20
Calculate the net force of the object on page 8.
700N to the right/east
What tide occurs during the moon phase on page 11?
What is the Octet Rule?
An atom is stable if it has 8 valence electrons on the outermost shell!
What is the volume of the swimmer on page 4?
8mL
How many valence electrons does chlorine have?
7 valence electrons
Calculate the net force of the object on page 7.
15N to the right
What is responsible for the change in tides each day?
The moon!
Why does the moon orbit the Earth? (HINT: Same reason why planets orbit the sun!)
The Earth's gravitational pull on the moon
All three boxes on page 5 have the same mass. What is different about them?
Their volumes and their densities
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.
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!
Looking at the Sun-Earth-Moon diagrams on page 12, which one (A, B, C, or D) represents a solar eclipse?
A
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
Using the solubility chart on page 3, at what temperature is the solubility of KCL the same as KNO3?
About 22-23 degrees.
Identify the element on page 6.
Spring force and gravitational force!
Looking at the Sun-Earth-Moon diagrams on page 12, which one (A, B, C, or D) represents a lunar eclipse?
C
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
