The model below shows the solar system. Which statement about the model is true?
The sun is bigger than any of the The model below shows the solar system.
A scientist puts together a table that compares the terrestrial planets in the solar system and their atmospheric compositions.
seasons on planets other than Earth
The diagram models the position of Earth as it orbits the sun. How does this model help to explain seasons on Earth?
It shows how Earth’s tilt and orbit around the sun affect the amount of direct sunlight an area.
Several students in a science class are trying to explain what the arrow in the image representsand how it affects the orbit of the planet
Jayden - The force of gravity from the sun pulls on Earth and causes Earth to move
Below is a diagram that shows an asteroid in Earth’s orbit. Which of the following best describes the phenomenon seen in this diagram?
Gravity is holding the asteroid in orbit of the sun.
The following is a model that represents systems in space.Which of the following describes Earth’s position?
Earth is part of the Milky Way universe, which is part of the solar system.
A science student wants to develop a model that represents gravity’s role in the universe. The student draws the current solar system as student draws the current solar system as shown below.
The student would add more stars and moons to the solar system next to the planets.
Assume that the diagram depicts Earth moving counterclockwise around the sun.
The side of Earth that is facing the sun is experiencing day.
Some friends are playing a game called croquet. One player uses their mallet to hit their ball into
another ball. The first ball slows to a stop, and the second ball starts rolling.
Jen says that energy from the the mallet was transferred to the first ball and then to the sec
A student makes a balloon cart to investigate how combined forces create motion. The student
creates a simple cart by attaching wheels to a small piece of cardboard. The student attaches a
straw with a balloon on one end so that any air coming out of the balloon flows in one direction.
The forces pushing the cart forward were greater than the force of mass and gravity.
On March 24, Leonore notices a beautiful waxing crescent moon right after sunset. From her
point of view, the moon appears in the night sky as shown here. She wonders what the moon will
look like that same night to her friend Reo in Japan.
Leonore considers her class notes and produces a diagram. She knows that the moon takes
almost a month to orbit Earth, but Earth rotates once every day.
He will see a waning crescent moon
The moon’s appearance from Earth differs through its various phases. Draw a line to match
the images of the moon (viewed from Earth) to the correct term describing its phase in the
lunar cycle. Then write numbers 2–4 on the lines to complete the sequence in which the moon
appears as shown.

During a solar eclipse, the moon blocks most of the sunlight shining on some parts of Earth. The
sun’s diameter is almost 400 times bigger than the moon’s. However, the sun is also almost 400
times farther from the Earth than the moon. This is why the moon and sun appear to be about
the same size as viewed from the surface of Earth.
Venus is close to the same size as Earth. Its diameter is more than three times as big as the
diameter of the moon. Venus is many times farther from Earth than the moon.
Venus blocks most of the sunlight.
What is the scientific reasoning that explains the observations of Venus’s orbit?
Because Venus is about the same size as Earth, it blocks a lot of sunlight.
Using a remote telescope, your class was able to take photos of Jupiter over the course of 10 hours
one winter night. You sketched the location of Jupiter’s moon Io, as shown below.
It takes Io about 40 hours to orbit Jupiter
You use objects of different mass, as shown in the table, in a collision of Object A with Object B. Part A – In which trial will Object B
Trial 3
Part B – Why did you choose this answer?
The acceleration of Object B = AA × mB, where AA = the acceleration of Object A and mB = the
mass of Object B.
Two objects on the air hockey table are pushed toward each other. The objects are of equal mass.
The sizes of the arrows are proportional to the acceleration. What is the most likely outcome of
the collision?
Both objects will move in opposite directions to the ones shown by the arrows.
Your team is provided with two test materials, C and D. You test the two materials using the air
hockey table to collide Object A with Objects C and D. The test material objects are the same size
and shape and are very similar in mass. The results are shown in the diagram. The sizes of the
arrows are proportional to the acceleration.
the correct answer is D. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. In the context of a helmet, this means that during an impact, the head will continue to move until a force stops it.
You review a report the team has prepared about their investigation. Circle the correct words or
phrases in each set of brackets to complete the sentences.
For any given object, a larger force causes a larger change in motion.
