Front

What is a 2D object that can be rotated to form a 3D object?

Back

A 2D object, such as a circle, can be rotated around an axis to form a 3D object, like a cylinder.

Front

What is the result of slicing a cylinder horizontally?

Back

The result is a circle.

Front

What is density?

Back

Density is the mass of an object divided by its volume, typically expressed in g/cm³.

Front

How do you calculate the side length of a cube given its mass and density?

Back

Use the formula: Side length = (mass/density)^(1/3).

Front

What is an observational study?

Back

An observational study is a research method where the researcher observes subjects without manipulating any variables.

Front

What is the formula for the volume of a cube?

Back

Volume = side length³.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, while mass is the amount of matter in the object.

Front

What is the significance of Jane Goodall's research method?

Back

Her observational study allowed her to gather data on chimpanzee behavior without influencing it.

Front

What is the formula for the volume of a cylinder?

Back

Volume = π × radius² × height.

Front

What happens when you rotate a rectangle around its longer side?

Back

It forms a cylinder.
