Students in Room 112 participated in a school-wide Eco Project revolving around the effects of salt on the environment. Our class decided to find out how to remove salt from salted water. We created little booklets to describe the steps involved in conducting the experiment.
Materials
- big (salad) bowl
- 2 teaspoons of salt
- 1 liter of distilled water
- plastic wrap
- empty cup
- sunlight
Step 1:
Place an empty cup in the middle of an empty salad bowl. Pour 1 liter of distilled water into the salad bowl and add two teaspoons of salt. Mix well.
* Be careful not to pour water or salt into the empty cup.
Step 2:
Seal the bowl with plastic wrap and place it near a window to allow for sunlight to penetrate.
Step 3:
Examine whether the level of water is beginning to decrease and whether water appears in the empty cup.
Big Idea
Students examine the different stages of the water cycle (i.e. evaporation, condensation, precipitation) and understand how salt is formed in the environment. Through the experiment, students examine how salted water begins to evaporate and form droplets on the plastic wrap which fill the empty cup. As the cup fills with drinkable water, the outside remains with salt.
Et voila!
After 3 days:
After 1 week:
Mini booklets written and published by students in Room 112 to be showcased at Eglinton Square Mall.
Bravo les amis!
