Collecting
water samples
You will need about 5 samples of water to test. The class should
all bring in a sample of tap water from home. If you have a water
softener, then bring a sample from this tap as well. If you have
a pond in your garden, ask permission from your parents to collect
water from this. Your teacher will also bring in some samples of
river water.
Take
Care!!!
To carry out each test you will need some water samples. You need
to be really careful around water. Sometimes water that looks shallow
can be very deep. There are often water plants below the surface
which could wind around your legs and trap you under the surface.
Never collect samples of water from a river, pond or lake on your
own. You should always have an adult with you.
Collect your water samples from the edge of the water. You don't
need to go in!!
Some water samples could be dirty, so make sure all cuts and grazes
are covered with waterproof plasters. Wash your hands in clean water
after collecting your samples.
