The Great Beyond
If the Earth did not tilt on its axis as is revolved around the Sun, what would happen to our seasons?
What is we would not have seasons?
The weather would stay the same all year round.
This type of heat transfer happens through direct contact, like a spoon getting hot in a tea cup.
What is Conduction?
True or False: In space, there is no atmosphere to breathe, so humans must carry their own oxygen.
True
According to the Particle Theory, are particles in a solid completely still?
No, they are constantly vibrating.
What is the primary source of almost all heat and light energy for our planet?
What is The Sun?
This is the name of the Canadian astronaut who currently returned from a trip on the Artemis II.
Who is Jeremy Hansen?
This type of heat transfer travels in waves and is how the Sun warms the Earth.
What is Radiation?
Why does the Moon appear to "glow" at night even though it doesn't produce its own light?
What is it reflects light from the Sun?
What happens to the speed of particles when you add heat energy to them?
Which state of matter has the most kinetic energy?
What is Gas?
This is the name for the path an object takes as it revolves around another object in space.
What is Orbit?
Why does hot air rise and cold air sink?
Hot air is less dense; Cold air is more dense
Name one challenge a human body faces when staying in microgravity for a long time.
Muscle loss, bone density loss, fluid shift
This is the term for when a solid turns directly into a gas, skipping the liquid phase.
What is Sublimation?
Ms. Muzzo put a shoe in the freezer with a ZipLock bag of water. What was the purpose of that?
To freeze the water and expand the shoe and make it more comfortable to wear.
Explain the difference between a rotation and a revolution and how it relates to time.
Rotation: spinning on an axis/causes day and night; Revolution: traveling around the sun/causes years
In a house, why are heating vents often placed on the floor while cooling vents are often near the ceiling?
What is - Because of Convection - hot air is less dense and rises from the floor up while cold air is more dense and sinks from the ceiling down
What is the difference between a Waxing moon and a Waning moon?
What is - waxing means the visible part is getting larger and waning means it is getting smaller?
When a substance is heated, the particles move further apart, causing the object to get slightly larger. What is this called?
What is Thermal Expansion?
Give an example of a "Sustainable Practice" that helps reduce the amount of greenhouse gases (heat-trapping gases) in our atmosphere.
Solar power, biking instead of driving, walking, etc.
Name the 8 planets in order from the Sun.
What is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
Explain how a "Convection Current" works using a pot of boiling water as an example.
(Water at bottom heats up, becomes less dense and rises; cooler water sinks to take its place)
This is approximately how many days it takes for the Moon to complete a full cycle of its phases.
What is 29.5 days? (or 28-30 days)
Describe the particle arrangement in a gas compared to a liquid
(Gas: far apart, moving fast, no fixed shape; Liquid: close together but sliding past each other)
If you were standing on the Moon and dropped a hammer and a feather at the same time, which would hit the ground first?
