 What is a thermometer?

A thermometer measures

temperature.

Temperature is measured in

Fahrenheit or Celsius.

A thermometer contains mercury which

is the red liquid in the thermometer.

 When the temperature rises so does the

mercury, when the temperature falls so

does the mercury.

Can you find 100 degrees Fahrenheit on

the thermometer?

Color the thermometer red all the way up

to 100 degrees Fahrenheit.

Practice reading different temperatures

on the thermometer!

Date_______ 

Today’s temperature: 

Yesterday’s temperature: 

Change:

Explain in detail today’s temperature and how the air feels, then compare it from yesterdays

temperature. Describe the change in the two days.

Draw what it looks like outside today.

Materials:

clear, plastic bottle (11oz. water bottle works)

water 

rubbing alcohol

clear plastic drinking straw

modeling clay

food coloring

Procedure:

Fill about 1/4 of the bottle full with equal parts of water and rubbingalcohol.

Add a few drops of food coloring.( I like Red)

Put the straw in the bottle, but don't let it touch the bottom.

Use the modeling clay to seal the neck of the bottle, so the straw

stays in place.

Place your hands on the bottom and record what happens on log

page.

Explanation:

 What happened?

Just like any thermometer, the mixture expands when it is warmedup. The heat made the mixture not fit into the bottle. As the alcohol

expanded the colored mixture moves up through the straw. If the bot-

tle were to get really hot the water would pour out of the straw.

Make Your Own Thermometer!

Experiment: What is hot and What is Cold?

Materials:

Two bowls

One with ice water 

One with hot water Thermometer 

 Worksheet

Timer; stopwatch

Ask students which bowl is hot and which is cold.

Ask students if they think the temperatures of the two bowls will be

the same.

Have students make a hypothesis and write it on the worksheet.

Procedure:

Put the two bowls side by side and have your thermometer ready. Place

thermometer in hot bowl for 1 min. Let the thermometer rest and record

temperature in degrees Fahrenheit. Place in cold bowl for 1 minuet.

Record temperature.

Discuss how the two temperatures are different. Tell them to look at

their recorded temperatures. Notice how the red mercury lines in both

thermometers are at different levels. This means they are at differenttemperatures. Ask the students which temperature is colder? Hotter?

Explain the lower the temperature or mercury level the colder it is, and

the hotter it is the higher the temperature or mercury level will be.

Repeat this in multiple locations (ex outside & inside; in refrigerator &

outside of refrigerator)
