# Students kit Heat

Thermometers teaching unit.
Children learn how to make a thermometer by themselves, how to use it and how to determine freezing and boiling points of water on
a thermometer without scale.
This way they learn the basic terminology and theories of heat and thermal expansion.

Evaporation and condensation teaching unit.
Children learn to understand the water cycle by finding out what happens when a liquid is converted into a gas and that a gas can be converted back into a liquid.

Age 7-9
Materials for 15 workgroups (for 30 children)

Art. no. 31799

### Technical specifications

Size of kit: 540 x 450 x 150 mm

experiments
• 1 - Heat

### experiment "Heat"

We will shortly provide you with a description of the experiment at this point.

• 2 - We heat water

### experiment "We heat water"

The students should be able to describe the following observations based on their experiments: When the water in the flask was heated, it rose in the glass tube (it expanded); when it was cooled again, it sank (contracted) in the glass tube.

• 3 - What do you need a thermometer for?

### experiment "What do you need a thermometer for?"

The students should get a feeling for different temperatures.

• 4 - My scale

### experiment "My scale"

In the sense of the aforementioned learning objective, the students should be able to make an individual division of the scale and one that corresponds to the consensus of the group and thus be able to measure.

• 5 - Taking temperature measurements and reading exercises

### experiment "Taking temperature measurements and reading exercises"

The students measure different temperatures in their environment.

• 6 - We heat spirit

### experiment "We heat spirit"

The spirit in the beaker is shown and possibly passed around. The students should try to find out for themselves what the subject is.

• 7 - A thermometer

### experiment "A thermometer"

The student groups receive the scaleless thermometers and two beakers with water at different temperatures. They take turns holding the thermometers in the glasses and observing them.

• 8 - The Celsius scale

### experiment "The Celsius scale"

The students should be able to use ice and boiling water to mark the melting and boiling points of water on a thermometer without a scale.

• 9 - The clinical thermometer

### experiment "The clinical thermometer"

We will shortly provide you with a description of the experiment at this point.

• 10 - Experiments with cologne

### experiment "Experiments with cologne"

The students are asked to formulate a hypothesis about the behavior of a drop of cologne exposed to air.

• 11 - We're investigating more liquids

### experiment "We're investigating more liquids"

The students should be able to name different non-potable liquids that are used in their environment.

• 12 - We measure temperatures while a liquid is evaporating

### experiment "We measure temperatures while a liquid is evaporating"

The students should feel and measure the impression of cooling left by an evaporating liquid.
