Science Week

8th - 12th March

Innovating for the Future

 

During Science week this year, we created fact files on Elijah McCoy, who was an inventor and created oil to make trains run quicker. His invention meant there was a reduction in pollution and the quantity of oil needed for travel. During the week we also planned and created our own Rube Goldberg devices! We worked in groups and found the most inefficient way to create a chain reaction, it was a lot of fun! 

Sound

 

In our sound topic, we have looked at how sounds travel, how we hear, what is in our ear and the dangers of loud noises. With our bodies, we recreated the form of solids, liquids and gases and identified that sounds travel best through solids as the molecules are close together. We also researched how dolphins can hear different noises than humans! This is because they have ultrasound and can hear very high pitched noises. We now know what decibels are. Did you know a whisper is about 30 dB, a normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. If we listen to noises over 70 dB for a long time, we can cause damage to our ears.
