This is the first step in the scientific method where you identify what you want to investigate.

What is the problem or the question?

200

This biome experiences moderate rainfall, has distinct seasons, and contains trees that lose their leaves in the fall.

What is deciduous forest?

200

This process in the nitrogen cycle involves bacteria converting or fixing nitrogen gas from the air into a form plants can use.

What is Nitrogen Fixation?

200

This process happens when animals breathe, releasing carbon dioxide back into the atmosphere.

What is respiration?

Three doctors said that Bill was their brother. Bill says he has no brothers. How many brothers does Bill actually have?

None - Bill has 3 sisters

400

In this step of the scientific method, scientists make educated guesses based on their knowledge.

What is the hypothesis?

400

This biome is characterized by extremely cold temperatures, low precipitation, and frozen soil known as permafrost.

What is Tundra?

400

This process occurs when bacteria break down dead plants and animals, returning nitrogen to the soil as ammonia

What is decomposition?

400

This process occurs when decomposers break down dead plants and animals, releasing carbon into the soil and atmosphere.

What is decompisition?

400

It’s midnight now, and it’s raining. The weather forecast says it will be warm and sunny for the next two days. Will it be sunny in 48 hours?

No! Because in 48 hours it will be midnight again.

600

After testing your hypothesis, this step involves looking at the results to see if they support or contradict your hypothesis.

What is analysis?

600

This biome is known for hot summers, cold winters, and is home to animals such as bison and prairie dogs.

What is grasslands?

600

This process in the nitrogen cycle involves bacteria turning nitrates back into nitrogen gas, releasing it into the atmosphere.

What is denitrification?

600

This process involves plants using sunlight to turn carbon dioxide from the air into glucose.

What is photosynthesis?

600

I can be cracked, I can be made,
I can be told, I can be played.
What am I?

What is a joke?

800

This is the variable that is changed or manipulated in an experiment.

What is the independent variable?

800

This biome is found around the equator.

What is Tropical Rainforest?

800

This is the process through which humans and animals absorb nitrogen.

What is consumption?

800

When fossil fuels are burned for energy, this releases large amounts of carbon dioxide into the atmosphere, a process called.

What is combustion?

800

There’s a one-story house where everything is yellow. The walls are yellow. The doors are yellow. Even all the furniture is yellow. The house has yellow beds and yellow couches. What colour are the stairs?

There are no stairs - it's a one story house

1000

The results from this part of an experiment are measured and recorded to see the effect of the independent variable.

What is the control group?

1000

This biome is found in regions with long winters and short summers, with coniferous trees such as pines and spruces dominating the landscape.

What is Taiga?

1000

These organisms, found in the roots of leguminous plants like beans and peas, help fix nitrogen from the air into a form plants can use

What is (nitrogen-fixing) bacteria?

1000

This is the process by which carbon dioxide is absorbed by the ocean, helping regulate the Earth's carbon levels.

What is Ocean Absorption?

1000

The more of this there is, the less you see.
What is it?

What is darkness?
