Another fantastic House Of Science kit.
We learnt about filter feeders. We had some ordinary sea water which we poured into a funnel through some filter paper. The green glitter represents all the goodness that the filter feeder takes out of the water.
We then used contaminated water which left green and gold glitter on the filter paper.
This demonstrated that if there are pollutants in the water they are still being absorbed by the filter feeder animals. This can mean they are poisonous to humans who then eat them.
We also looked at videos of the Rena disaster.
