This part of the electromagnetic spectrum is what we can see.
What is the visible spectrum
100

What do all living things do?

Grow, move, respond to stimuli, reproduce

100

Name an organ in the nervous system.

Brain, spinal cord etc.

200
This is the light ray that first hits the mirror
What is the incidence ray
200

A light ray travels from a less dense medium into a more dense medium, which way does the light ray bend? (towards or away from normal)

What is towards the normal

200
Name all the colours of the visible spectrum
What is ROYGBIV
200

What is the role of cytoplasm?

Jelly-like fluid that the organelles float around in, it helps move materials around the cell.

200

What is the role of the excretory system?

To remove waste, extra water and salt from the body.

300
If the angle of incidence is 54 degrees, the angle of reflection will be?
What is 54 degrees
300
True or False: A convex lens causes light to converge.

True

300
This type of electromagnetic radiation is responsible for the sunburns we experience when we're in the sun too long.
What is UV radiation
300

What is the role of the nucleus?

Contains DNA and is the control centre of the cell.

300

How does the muscular and nervous system help us read a book?

The muscular system holds our bones in place to hold the book and turn the pages, our nervous system includes our eyes and brain, which is reading the words on the page.

400
This is the type of reflection that happens when a light ray hits a smooth surface
What is specular reflection
400
In which medium would light travel the slowest: space, air or water?
What is water
400
This type of electromagnetic radiation creates images of our bones on films
What is X-rays
400

What organelle is found in plant cells that isn't found in animal cells? (2)

Cell wall and chloroplasts

400

How does the digestive system work with the nervous system?

The nervous system sends and receives signals that tell us if we're full or hungry, and it also receives taste signals. The digestive system relies on these signals to activate certain chemicals.

500
This is the type of reflection that occurs when light rays hit an uneven surface (i.e. side of a mountain)
What is diffuse reflection
500

Name a real world application for refraction. (What do we use it for?)

Glasses, Microscopes, VR headsets etc.

500
This type of radiation is also a common way that we heat our food
What is microwaves
500

What is the process called when cells divide?

Mitosis

500
