Water Exploration

The last few days, we have had many discussions about waterways, lakes, oceans and ponds.  We used a map to identify countries and oceans the Wild Kratts have explored and countries that some of our friends have visited.  In our study of the natural world, we compared a pond and a lake. During our discussions, we talked about animals that live in salted and fresh water and others that live in cold and warm water.  The children also had the opportunity to explore the buoyancy of a bar of of soap in fresh and salted water.

Est-ce que le savon flotte?

The children were encouraged to use tally marks to record their answers.

The children observed some table salt using a magnifying glass and made the following observations after being asked what it looks like or  what does it make you think when you look at the salt:

Kaitlyn: Snow

Giuliana G.: Grass

Joanna-Lee: Circles

Folu: A circle.

Christina: I can see a triangle.

Ben: I can see circles.

Alessa: A big circle.

Fouad: circle

Ella: Sugar (Why?) because it is white like sugar.

Hannah: It makes me think of sugar.

Nahisha: Shape like circles.

Colin: Sugar because it is white.

Sean: It looks like yellow crumbs.

Devin: Looks the same. Salt does not make you slip.

Alessio: A diamond.

Mahmoud: A circle.

Giuliana M.: Looks a little bit powder.

Tianna: Looks like a big circle.

Brandon: It has circles.

Jackson: circles

Preston: A circl.e

James: Looks like circle.

Here is the salt after the water evaporated.

 Then we added some hot water. The children observed that the salt "melted," that "it looks like water" and "it looks like a cloud". We told the children that we would let the water evaporate and that we would continue to observe. After all the evaporation of water, some children made the following observations:

Alessa: The water is all dried up. It's dried up because it's salty.

Arman: So salty and dried up.

Christina: It looks like all the way down to the bottom. It's dry. I think you have to put more water. Is it going to stick a lot of times?

Ella: It looks like frozen salt.

Devin: It looks really dry, no water, just salt on the sides. Something looks weird. It looks like dry water, dry salt.

Ben: It looks like a cricle. The water came out except the salt. It looks like a semi-circle.

James: It is really tiny. I think there's no more (water).
