True or false: all matter is made of tiny particles that are always moving

TRUE

100

Explain internal versus external forces

Forces that act WITHIN an object (e.g., a beam being twisted or squeezed)

Forces acting ON an object from the outside

100

Explain biotic and abiotic factors, and give examples

Living and Nonliving

What objects emit light? what does this mean?

Lightbulb, computer screen, sun, stars

What is abstraction in coding and/or other contexts?

  • Abstraction means simplifying a complex system by focusing only on the important details and ignoring everything else.
  • Example: When you drive a car, you use the steering wheel and pedals without needing to understand the engine mechanics. The complexity is "abstracted away."

Explain how expansion and contraction relate to temperature

  • Heating: Particles move faster, attractive forces weaken, particles spread farther apart. Result: Expansion.
  • Cooling: Particles move slower, attractive forces strengthen, particles move closer together. Result: Contraction.

What is Newton's Third Law?

For every action force, there is an equal and opposite reaction force.

200

What is photosynthesis? 

Sunlight + Water + Carbon Dioxide (CO2) → Glucose (Sugar) + Oxygen (O2)

Bonus: Chlorophyll is the green pigment in plant leaves that captures sunlight energy to power this process.

200

What objects in space reflect light?

comets, moon, spacecraft, asteroids

200

Explain a loop, a sequence, and a conditional in coding

Repeats a set of instructions

Steps carried out in order, one after another
Makes a decision based on a condition

300

What is the main benefit of the Celsius scale for temperature?

Melting/freezing + boiling point of water

300

Explain elasticity versus plasticity

  • Elastic: The material returns to its original shape after the force is removed.
  • Plastic: The material is permanently deformed -- it does not return to its original shape.

In many Indigenous cultures, there are four sacred plants -- Sage, Sweetgrass, Cedar, and Tobacco -- represent balance and a sustainable relationship with the land. How does this demonstrate stewardship and interdependence with living systems?

Give examples of space technology 

  • Telescopes: Observe distant objects without travelling to them.
  • Rovers: Explore the surface of planets and moons.
  • Satellites: Orbit Earth and other bodies; used for data collection, communication, and environmental monitoring.

A student uses a TV remote without knowing how the remote sends signals to the TV. Which coding concept does this best illustrate?

abstraction

400
Give an example of an engineer considering temperature when they build something
  • Engineers build expansion joints (gaps) into bridges, sidewalks, and train tracks so the materials can expand in heat and contract in cold without cracking.
400

Give an example of a force and explain it 

Tension, compression, shear, friction, gravity, spring/elastic, torsion

A student covers all the leaves of a houseplant with black bags for two weeks. What is the most likely result?

The plant starts to struggle/die because it cannot perform photosynthesis without light

400

Give one characteristic to describe every single planet in our solar system

Explain independent, dependent, and controlled variables in the context of the Scientific Method.

  • Independent Variable: The one thing you CHANGE in an experiment (the cause).
  • Dependent Variable: The thing you MEASURE (the result -- it depends on the independent variable).
  • Controlled Variables: Everything else you keep the SAME to make the test fair.

A student places an ice cube in a sealed container and weighs it. She then lets the ice melt completely and weighs it again. What will she notice about the mass of the ice versus the water?

Mass stays the same during phase changes

Explain renewable versus non-renewable energy resources, and explain direct versus processed energy

Answers will vary

Give an example of a food chain that contains consumers, producers, and decomposers.

Answers vary

We can see the Moon at night because:

Even at night, the moon is reflecting sunlight toward Earth. It does this during the day as well, but we can't always see it in the day because the actual sunlight overpowers the reflection.

3 Write a hypothesis for the following experiment: A student wants to know if the amount of water given to a plant affects how tall it grows over 4 weeks. Use the "If... then... because..." format.

"If plants receive more water each week, then they will grow taller over 4 weeks, because water is a necessary ingredient for photosynthesis and cell growth." (Independent variable: amount of water. Dependent variable: plant height.)
