Land and Water Forms- Archipelago and System of Lakes

P1110196

This week the children were introduced to the idea of an archipelago and a system of lakes. They took the land and water forms to a table and were given a lesson on pouring water into the forms. This was very timely as we had students return from Hawaii this week. (Notice the spill of water on the table, this is a great lesson in cleaning up. We have blue cloths that the children use to clean up spills. They can all do this independently now.)

As an extension to this lesson, the children feel the small sandpaper land and water forms and then color a paper to take home.

Cape and Bay

P1110150

This week we studied cape and bay. The children were given lessons on how to pour water into the different land and water forms.

Some children then went on to use the sandpaper land and water forms to give a tactile impression and then color their own cape and bay.

Geology- The Layers of the Earth

The four layers of the Earth. Although most of our lessons are given individually (such as practical life, math and language) at times the children gather in a small group for a special presentation. We had purchased a model of the Earth that splits in half and also had printed out our nomenclature cards for the children to match showing the different layers of the Earth.

We discussed each layer: the inner core, the outer core, the mantle and the crust.

Cutting a earth model

I then showed them a playdough Earth I had made the night before and proceeded to cut through to see the various layers. (Of course, this gave us a chance to discuss knife safety!)

We passed around the two halves and pointed out the different layers.

After the presentation, many children chose to make their own Layers of the Earth booklet.

One child also pin-punched each layer and glued on to make a little diagram.
