Living Systems
The organism that makes it own food using sunlight.
What is Producer?
This describes day-to-day atmospheric conditions.
What is Weather?
Matter is made up of tiny units called this.
What is Particles?
This variable is changed by the scientist.
What is Independent Variable?
A student in Calgary sees the Sun rise in the morning and set in the evening.
What movement of Earth causes this pattern?
What is Rotation?
This process allows plants to make food using sunlight, water, and carbon dioxide.
What is Photosynthesis?
This greenhouse gas is released when fossil fuels are burned.
What is Carbon Dioxide?
The change from liquid to gas.
What is Evaporation?
This variable is measured during an experiment.
What is Dependent Variable?
A student notices that summer and winter happen every year.
What movement of Earth is responsible for this yearly cycle?
What is Revolution around the Sun?
This organism breaks down dead plants and animals.
What is Decomposers?
This type of energy source includes wind and solar power.
What is Renewable Energy?
The change from gas to liquid.
What is Condensation?
Variables that stay the same are called this.
What is Controlled Variables?
This planet is often called the Red Planet because of the iron-rich dust covering its surface.
What is Mars?
In the food chain Grass → Rabbit → Fox, this organism is the primary consumer.
What is Rabbit?
This term describes long-term weather patterns in a region.
What is Climate?
When matter is heated, particles do this.
What is Move Faster?
A student wants to find out whether the amount of water affects plant growth. She gives one plant 50 mL of water each day and another plant 100 mL each day.
What tool would be MOST appropriate to collect data about the plant growth, and what should she measure?
A ruler or measuring tape. They should measure the height of the plants.
If Earth stopped revolving around the Sun but continued rotating, which phenomenon would continue to occur?
A. Seasons
B. Day and night
C. Moon phases
D. Years
What is Day and Night (B)?
A disease causes the grass population in an ecosystem to decrease significantly.
Explain two ways this could affect other organisms in the food web.
Name one effect of climate change.
What is...Rising temperatures, melting glaciers, rising sea levels, extreme weather, etc.?
A community wants to reduce its carbon footprint.
Name TWO actions they could take and explain how each helps reduce greenhouse gas emissions
Examples:
A student wants to determine whether music affects how quickly bean plants grow.
She places one plant in a room with music and one plant in a quiet room. Both plants receive the same amount of sunlight, water, and soil.
Identify:
A student claims:
"The side of the Moon facing Earth changes as the Moon moves through its phases."
Is the student correct?
No. The same side of the Moon always faces Earth. Moon phases occur because we see different amounts of the Sun-lit portion of the Moon.
