“Protecting our Water”



Activity 3: Who Lives Here? – Aquatic Habitat (Quest)

The focus of this activity is to understand how plants and animals rely on other plants and animals to exist. Specifically, they will look at ponds, which contain lots of different types of life. They can begin the activity brainstorming with a group what they would expect to find in a pond. From here, they should write down at least 10 plants or animals that they would expect to find in a pond. They should also write about how these plants and animals rely on one another. Specific goals are listed below:




  • Brainstorm with fellow Questers about the life forms that might be found in a pond.

  • Write down all the responses from your group.

  • Narrow your discussion, based on the written responses, to ten plants and animals that you would expect to find in a pond.

  • Create a chart showing your list of plants and animals.

  • Brainstorm with a group of Questers how these plants and animals might rely on one another and what their relationships might be.

  • Write down all of your group's responses and add this information to your chart.

  • Use the Internet, books, field guides or interviews with a scientist, environmentalist, or biologist to find the answers to your questions.

  • Add a final column to your original chart that shows the answers you and the other Questers discovered through their research.

  • Submit your chart to the Council through the OTAK.

Note: your students can also do this as a Quest by having them (as individuals or through groups) enter the Quest Atlantis environment and complete the “Who Lives Here? – Aquatic Habitat” Quest in which each student (or group if Group Questing) provides her own solution to the Quest. As a Quest, you can then respond to children’s work individually or as a group if they decided to Quest as a group.

“Protecting our Water”



Activity 4: Runoff Experiment

In this activity your students can do a runoff experiment to better understand how water becomes polluted.



Procedure:

  1. Put a piece of fine screen, nylon mesh or stocking in the bottom of the funnel.

  2. Fill the funnel with sand.

  3. Place the funnel in the mouth of the gallon jar.

  4. Pour one cup of water over the sand. Wait until no more water flows out of the funnel.

  5. Remove the funnel and pour the water in the jar into the one-cup measure. How much water was in the jar? Where is the rest of the water?

  6. Put the funnel back in the jar. Drop 2 or 3 drops of red food dye onto the wet sand in the funnel. Slowly pour one cup of water over it.

  7. Observe how much of the food dye washes through the sand into the jar and how much remains trapped in the sand. Dump the water out of the jar into a bucket or sink.

  8. Continue pouring one cup of water at a time over the sand. Discard it if the water that flows out of the funnel is colored red or pink.

  9. Repeat the process until the sand is rinsed clean. How many cups of water did it take?

Reflections:

  1. Would you want to drink the water that filtered through the funnel? Why or why not?

  2. Predict how many cups of water it would take to flush the sand clean if you used blue or green food dye. Test your predictions.

  3. Find out if any pesticides and/or herbicides are sprayed in your community. Have any been found in local bodies of water? In what concentrations have they been found?

  4. Investigate the source of your local drinking water supply. How is it filtered and purified? What concentrations of various substances are allowed?

  5. Research one common water pollutant from the list below and prepare an oral or written report on the effects of that substance on human health:

Lead , Mercury, Nitrates, Arsenic, Cadmium, Selenium, DDT, Chromium.

You might want to have students write a reflection essay on how water gets polluted, or simply have a class discussion.
