Contaminated Water Experiments - Day 3

As you can see in the photos, the plants watered with salt water and acidic water are wilted and on their last legs. To our great surprise, the plants watered with the water contaminated with cigarette butts do not seem to have suffered the same damage. We will continue to make observations through next week.

Contaminated Water Experiments - Day 1

We set up our plant experiment today and watered each plant with contaminated water at 11 am. By 12 noon, you can see the effect on two of the plants.

The first 2 photos are of plants before watering. The third photo was taken at 12 noon. We have questions! Why was only one of the salt water and acidic water plants affected?

Contaminated Water Experiments

Students are completing their experiments designed to test the effect(s) of contaminated water on marigold plants. Students had class time to work on this and those who haven't finished need to complete their experiment write-up at home tonight.

Here you see experiments written by Colin, Jersey and Macy testing the effects of acidic water, salt water and water contaminated with cigarette butts. You will notice that they have identified the independent, dependent and controlled variables and written specific and detailed procedures so their experiments can be reproduced by grade 3 students.

We will be taking photographs of the experiments as they progress and posting pics in our blog along with observations.
