Water in the Environment
The
Water in the Environment module is designed to introduce students to the
importance of maintaining the availability of fresh water here on Earth. The
module also introduces students to the basic properties of water that allow
life on Earth to exist. Emphasis is placed on understanding the harmful
effects of pollutants in our lakes, rivers, streams, and groundwater. The
water module provides several visual and hands-on activities that teach
students about the importance of water. Firstly, students are taught about
the properties of water and the water cycle. Demonstrations illustrate the
properties of water such as specific heat and cohesion. The Earth is
presented as a closed system in which water is continually recycled.
Secondly, students are educated about where fresh water comes from. An
experiment with an aquifer illustrates how lakes and rivers are continually
refilled, and also shows how pollution from underground storage tanks and
leakage from landfills contaminates the water. A demonstration with a filter
column shows how layers in an aquifer filter wastes from water, and shows the
properties of water in action... Thirdly, students are taught about how
run-off can contaminate our freshwater and affect the food web. This
phenomenon is illustrated with a demonstration of how phosphates can cause
algal blooms which prevent light transmission into rivers, lakes, streams,
and even sections of ocean. |

Models
like the magnetic one in the Bio-Bus Fellow’s hand are used to talk
about the properties of water. |
We need 15
or fewer guests on the Bio-Bus in order for everyone to be able to see the
demonstrations. |
