We know that engineers think about ways in which to make life easier.
We know that engineers design and make things.
Today we were talking about global warming, the melting of the polar ice and flooding.
Along the way we tried a few other investigations:
We were really interested to hear that when polar ice melts, the colour of the area affected changes from white (ice and snow) to greeen, brown or blue (the colour of land or sea). Areas that are dark in colour absorb more heat and thus heat up more quickly than white areas. This causes the remaining ice in this area to melt even more quickly, making the area darker and so heating up more quickly. Of course, as we saw earlier land ice from the polar caps that melts causes the sea level to rise and causes flooding.
We can really see the connection now between global warming, melting polar caps and flooding. We are especially sorry for polar bears and penguins who make this ice their home.
