Thermic Bottles

Materials:

2 are filled with water from the hot water tap (should not be uncomfortably hot)
2 are filled with water at body temperature (lukewarm)
2 are filled from the cold-water tap
2 are filled with ice water, or water from a refrigerator

Purposes:

Age: 3 ½ - 4 ½

Preparation: The child is working with other Sensorial pairing exercises

Presentation 1: Pairing

Introduction:

**Before you invite the child you will have previously prepared the bottles or you can have the child help.

Invite the child for a lesson on the Thermic Bottles, show them how to carry the box, return it to the shelf and have them take it to the table.
Always moving them by the handle, remove one set of the bottles by handles and line them up on the right side of the table, top to bottom.
Place one in front of the child.
Rub your palms on your pants to neutralize them.
Grasp the bottle in the left hand and then the right to feel the temperature.
Invite the child to feel the bottle.
Move the bottle to the left top side of the table. Subsequent bottles are lined up one below the next.
Repeat for the rest of the bottles.

Pairing

When all are on the left, line up the other set on the right side of the table. Remove them in the same order as the first set, but line up starting at the bottom of the table.
Select the bottom left bottle and place it in front of the child
Select the bottom right bottle and set it beside the other.
Neutralize hands.
Grasp the left bottle in the left hand and the right bottle in the right hand to feel the temperatures.
If they do not match, place the right bottle on the table next to the box.
If they do match, place them side by side in front of the box.
Move the bottles that did not match back to the right side of the table
Repeat until they are all paired OR if the child really wants to do it-hand it over to them after two pairs.
Separate the pairs to each side of the table and invite the child.
Fade and observe once the child is comfortable with the process.
When the child is done, show the cleanup process by emptying the bottles in the sink and letting them dry in the dish drainer (so they don’t get rusty).

Control of Error:

Presentation 2: Grading

Gradation of one set of the bottles (this is hard to do).
Remove one set of bottles to the right side of the table.
Find the hottest and place it on the left side of the table. Return to base each time to order them in a horizontal line from hottest to coldest.

Language: Hot, cold cool, warm

Memory Games:

It is possible to do a distance game but because the bottles lose temperature so quickly, it is not practical.

Pedagogical Notes:

Preparation of the Bottles:
- Remove bottles by the handle, if they have one.
- Line up the bottles in two rows.
- Use a pitcher to fill a pair at a time.
- Fill to just the bottom of the threads.
Do not put the bottles in the freezer! You will forget about them, and the bottoms will blow out.
Do not leave water in the bottles on the shelf because they will rust.
The three-period lesson works best with two bottles. It lends to easier contrast.
