G7 Q2 Science Practice Assessment

Front

What is ultraviolet light?

Back

Ultraviolet light is a type of electromagnetic radiation that is invisible to the human eye and has a shorter wavelength than visible light.

Front

How does the speed of particles relate to heat in different states of matter?

Back

In gases, particles have the most heat and move the fastest, while in solids, particles are closely packed and move the slowest.

Front

What happens to the potential energy in a stretched rubber band when it is released?

Back

The potential energy stored in the stretched rubber band changes to kinetic energy when it is released.

Front

What is the best way to investigate if soil type affects plant growth?

Back

Design an experiment where you plant seeds in different soil types and measure their growth over time.

Front

In which medium does light travel fastest?

Back

Light travels fastest through air compared to other materials like plastic and water.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.

Front

What is the scientific method?

Back

The scientific method is a systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.

Front

What is the difference between a hypothesis and a theory?

Back

A hypothesis is a testable prediction, while a theory is a well-substantiated explanation of an aspect of the natural world.

Front

What is the role of control in an experiment?

Back

A control is a standard for comparison in an experiment, helping to isolate the effects of the variable being tested.
