Density helps someone identify unknown substances. What is the density (g/mL)of this unknown object:
Mass: 25 g
Volume: 100 mL
What is 0.25 g/mL?
D = M/V
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.
- Mutualism
- Commensalism
- Parasitism
What is commensalism?
This is the smallest unit of matter that still has all the properties ~ made of electrons, protons, neutrons.
What is an atom?
This variable is the one that is measured in a scientific experiment.
The color of a shirt affects the amount of heat it absorbs.
What is dependent/outcome variable?
Repeating the experiment over and over ~ completing more trials
What is repetition?
The tectonic plates of the earth move due to what kind of heat transfer happening in the Earth's mantle?
What is convection currents?
This is the process of converting water and carbon dioxide into oxygen and glucose, using the sun.

What is photosynthesis?
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
Identify the variables ~

What is increase temp?
Which eclipse can occur during a New Moon?

What is solar?
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?
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?
Type of heat transfer that travels by waves, can travel through space, and travels out in all directions (not touching)
What is radiation?
These are the three pieces of evidence that supports cell theory (need 2 of the 3)

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
Data that involves descriptive observations, such as the plants leaves being green and smooth, is called _____________.
Data that involves numbers and measurements, such as the length of a plant growing 15cm, is called _______________.
What is QUALitative & QUANTitative?
This kind of tide occurs during Full and New Moons (larger tides occur)

What is spring tides?
STRONGER + SPRING
(all in one line = stronger gravity = bigger tides)
