This variable is the ONLY variable to change in a scientific experiment.
The color of a shirt affects the amount of heat it absorbs.
What is the independent/test variable?

These two spheres of the earth are interacting in this scenario ~
A plant roots down into the soil in order to grow.
What is biosphere & geosphere?

This kind of symbiosis occurs when one organism benefits from the relationship and the other is unbothered. For example, when remora fish follow Sharks. They get leftover food from the Shark, and the shark is not harmed or helped by the Remora.

Repeating the experiment over and over ~ completing more trials
What is repetition?
200
The tectonic plates of the earth move due to what kind of heat transfer happening in the Earth's mantle?
What is convection currents?
200
This is the process of converting water and carbon dioxide into oxygen and glucose, using the sun.
What is photosynthesis?
200
This state of matter has a set volume and can change its shape. It has a definite volume but no definite shape.
What is a liquid?

When we look at a sample of rock strata and their layers, where can we expect to find the oldest fossils and rock layers?
What is the bottom?
older = deeper undrground

In science this is the process of repeating a study or experiment to verify its findings, ensuring reliability and accuracy
(repeating someone's experiment)
What is replication?
400
This plate boundary occurs when two tectonic plates move away from each other to form new crust, mid ocean ridges, and rift valleys.
What is divergent boundaries?

This organelle in the cell is the "brain" ~ controls everything.
What is the nucleus?
400
Type of heat transfer that travels by waves, can travel through space, and travels out in all directions (not touching)
What is radiation?

What is
All living things are made of one or more cells
Cells are the basic units of structure and function in living things
All cells come from other cells
