What have we been learning?
Our first topic was about evolution and how animals have adapted to survive in their habitats.
We researched an animal (e.g polar bear) to find out how it has adapted to its environment. We found out that the polar bear has thick layers of fat and fur to keep it well insulated against the freezing cold tempratures. This wonderful animal also has a greasy coat that sheds water after swimming to help reduce heat loss.
Why do you think the polar bear has a white coat?
Their white coat acts as a camouflage for when they are out hunting for prey to eat. Because they live where there is lots of snow and ice, their white coat helps them to blend in with their surroundings.
How Does Light Travel?
We have learnt that light can only travel in straight lines. We investigated this by getting into groups of three. One person had to hold a mirror, one had to have a word wrote on their back and the third person had to try and read what the word said using the mirror (shown above). The light bounces off the mirror to our eyes, but can only happen in a straight line.
