This specialized tool is required to see the tiny bacteria that make up your microbiome.

What is a microscope?
100

These two things are the "inputs" (reactants) that cells need to perform cellular respiration and create energy.

What is glucose and oxygen?

100

This is the invisible force that keeps the Moon in orbit around the Earth and the Earth in orbit around the Sun.

What is Gravity?

100

This is the direction that thermal energy always moves between a hot object and a cold object.

What is from the hotter object to the colder object?

100

When a substance changes from a liquid to a gas, the energy of its molecules does this.

What is increase (or move faster/further apart)?

200

This cell part acts like a "security guard," controlling what enters and exits.

What is a cell membrane?

200

This body system is responsible for transporting glucose and oxygen to your cells.

What is the circulatory system?

200

This moon phase occurs when the Moon is positioned directly between the Earth and the Sun.

What is a New Moon?

200

This term describes the state when two objects in contact reach the same temperature and heat transfer stops.

What is Thermal Equilibrium?

200

This is the name for the phase change where a gas loses thermal energy and turns back into a liquid.

What is Condensation?

300

These two structures are found in plant cells, but not in animal cells.

What are chloroplasts and cell walls?

300

This is the "output" gas we exhale as a byproduct of the chemical reaction in our cells.

What is Carbon Dioxide (CO2)?

300

During this specific event, the Earth’s shadow blocks the Sun's light from hitting the Moon.

What is a Lunar Eclipse?

300

Of the three types of heat transfer, this one occurs specifically through direct contact between particles (aka solids and similar states of matter).

What is Conduction?

300

On a heating curve graph, these specific sections represent a phase change occurring.

What are the flat (horizontal) lines?

400

Explain why a cell membrane must be semi-permeable rather than a solid, closed wall.

What is "To allow nutrients/oxygen in and waste out while keeping harmful things out"?

400

If a person’s respiratory system is damaged, explain why their metabolism (energy production) slows down.

What is "Because the body cannot get enough oxygen to break down glucose into usable energy"?

400

Identify the two main factors that determine the strength of the gravitational pull between two objects in space.

What are Mass and Distance?

400

This is the reason why a metal spoon feels hotter in a cup of cocoa than a plastic spoon does.

What is "Metal is a better conductor (or has higher thermal conductivity) than plastic"?

400

Even though you are adding heat to a pot of boiling water, the temperature stays at 160 degrees Fahrenheit. Explain where that extra energy is going.

What is "The energy is being used to break the bonds/attractions between the molecules to turn them into gas"?

500

Provide one piece of evidence to support the claim that the human microbiome functions as a system.

What is "The bacteria interact with our body to help digest food or fight infection?

500

Describe how the Digestive and Circulatory systems work together to provide energy to a leg muscle.

What is "The digestive system breaks down food into glucose, and the circulatory system delivers it to the cells for respiration"?

500

Explain why the Moon has a much greater effect on Earth's tides than the massive Sun does.

What is "Distance. Even though the Sun is massive, the Moon is much closer to the Earth, making its pull on the water stronger"?

500

Explain why a "vacuum" (empty space) between two layers of a thermos is the best way to prevent heat loss by conduction.

What is "Conduction requires particles to touch to transfer energy; since a vacuum has no particles, the energy cannot be transferred"?

500

Describe the difference in molecular arrangement and motion between a solid block of ice and liquid water.

What is "In a solid, molecules are locked in a fixed pattern and vibrate; in a liquid, they are close together but can slide past one another"?
