Summer term

Summer 1


This half term, we will be learning about electricity. We will be creating circuits as well as predicting whether a circuit will work or not. It is important to stay safe around electricity as it can be dangerous. We will investigate which materials make good electrical conductors and insulators.


All of our work in science will help us when we make our own torches in DT.


How is electricity created?

How does it get to our homes?

Summer 2


Our final science topic is all about sound.


How are sounds created?

How does a sound travel?

Why are some sounds louder or quieter?

How does the pitch change?

How do we hear sounds?


We will investigate how to make a sound quieter by testing different soundproofing materials.


Facts about sound


  1. Sound travels much slower than light, whether in air or in water. Light travels at 186,000 miles per second, whilst sound travels at 770 miles per hour. You often hear things after you see them; for example, you see the lightning before you hear the thunder.
  2. The sound of a baby's cry is very hard to ignore. This is because it alerts a special part of the brain. 
  3. We measure sounds that humans can hear in 'decibels'.
  4. Human ears can be damaged by loud sounds.
  5.  Sound volume (how loud a sound is) is measured in bels. Bels are named in honour of Alexander Graham Bell, who is credited with the invention of the telephone.
  6.  Dogs can hear much higher sounds than humans.
  7. The eruption of Krakatoa in 1883 is believed to be the loudest sound in human history. It was heard in an area spanning a thirteenth of the globe.
  8. Dolphins can hear sounds underwater from up 15 miles away.
  9. Most cows produce more milk if they are given music to listen to.
  10. Sound can travel around 4 times faster in water than in air.
