How are we able to see non-luminous objects? 

They reflect light received from luminous sources.

DAILY DOUBLE: We have seasons due to this. 

What is 'the tilt of the Earth's axis as it orbits the Sun'?

150

This muscle helps to change the shape of the lens in your eye, so that you can either focus on something near you, or look at something far away. 

What is the ciliary muscle?

150

This is the function of earwax.

150

This animal is capable of sensing sound frequencies of up to 300kHz – the highest recorded frequency sensitivity of any animal. 

What is a wax moth?

The law of reflection states that this angle must be equal to the angle of reflection.

What is the angle of incidence?

When does a solar eclipse happen?

What is 'When the moon gets between Earth and the sun' (fully or partially blocking the sun)?

200

The retina uses special cells to process light. One of these types of cells helps us to see black, white and grey, as well as the shape of an object, while the other type allows us to see colour. You have millions of them in each eye. These are called the.... 

What are the rods and cones?

200

The Eustachian tube runs down your middle ear. Its job is to equalize air pressure in your ear. It is connected to this other body part. 

What is 'the throat'?

200

This is why children have higher voices than adults. 

What is 'They have thinner and shorter vocal cords'?

When a straw is placed in a cup of water, it appears bent, due to refraction. Why does this happen?

When light waves enter the water, they slow down, causing them to change direction.
