Homemade Thermometer STEM Experiment

Objective:

Learn the basic principle of how a thermometer works by creating your own at home.

Ingredients:

• A clear, plastic, narrow-necked bottle
• Water
• Food coloring (optional)
• Clear straw
• Modeling clay
• Temperature chart (for reference)
• Marker or tape (for marking levels)

Instructions:

1. Prepare the Bottle:

• Fill the bottle about 1/4 full with equal parts of warm and cold tap water.
• Add a few drops of food coloring. This is optional, but it will make the water easier to see.

2. Install the Straw:

• Put the straw in the bottle, but do not let it touch the bottom.
• Wrap the top of the bottle with the modelling clay, securing the straw in place but also ensuring a seal around the bottle's opening, not allowing any air to escape.
• Note: make sure straw is sticking out of the clay seal - the top of the straw should be open to the air.

3. Adjust and Observe:

• Mark the level of the water in the straw and place your homemade thermometer next to the reference thermometer (if available).
• Observe and note down the water level in the straw at different times of the day, marking the straw at each interval. If possible, note down the temperature from the reference thermometer as well.
• Over time, the water level in the straw will rise and fall with temperature changes, you have created a basic thermometer!

4. Conclusion:

• If your child enjoys this experiment, they may also enjoy learning more about how professional thermometers are made and exploring other aspects of meteorology.

Create a Color-Changing Thermometer Experiment

Ingredients:

You will need the following items:

• Clear straw
• Modeling clay (non-hardening)
• Water
• Food coloring (red works best)
• Transparent glass
• Thermometer (for comparison)

Steps:

Follow these steps to create your own color-changing thermometer:

1. Take the straw and form a tight seal at one end using the modeling clay. Ensure no water can leak through.
2. Fill the glass with water.
3. Add a few drops of food coloring to the water and stir until the color is uniform.
4. Immerse the open end of the straw in the colored water, but make sure the clay-sealed end is not submerged.
5. Pinch the top of the straw and pull it out of the water. There should be colored water in the straw.
6. We are now ready to use our homemade thermometer. Place your sealed straw next to a real thermometer.
7. Observe and record the level of water in the straw as temperature changes. As the temperature rises, the water level should go up due to the expansion of the air in the straw.
8. Compare the changes in your homemade thermometer to the readings of the real thermometer for accuracy.

Introduction:

This is a fun and engaging activity to introduce kids to the basic principles of temperature and thermometers. By using household items to create a homemade thermometer, this experiment allows children to work with their hands and observe how different liquids respond to changes in temperature.

Ingredients:

• A transparent glass or plastic container (like a clear vase or water bottle)
• Three different types of liquids (water, rubbing alcohol, vegetable oil are recommended)
• Food coloring (optional but helpful)
• A straw and some clay or Play-Doh
• Tap water and ice cubes
• Thermometer for the comparison

Instructions:

1. Thoroughly clean and dry your container.
2. Now fill the container about 1/3 full with one of your liquids. For example, start with water.
3. Add a few drops of food coloring if you wish. This isn’t necessary, but it will make the liquid easier to see.
4. Insert the straw into the liquid-filled container but don’t let it touch the bottom.
5. Use your clay or Play-Doh to seal the top area of the container around the straw, ensuring it stands upright but can still move freely up and down. Make sure there are no air gaps.
6. Observe and note the level of the liquid in the straw. You have now completed your homemade thermometer.
7. Now take your homemade thermometer and a real thermometer and place them both into a bowl of tap water and note the level of the liquid in the straw and the temperature on the real thermometer. Then transfer both to a bowl of ice water and again note the changes.
8. Drain the container, ensure it’s dry, and repeat the process for the remaining two liquids. Compare the results.

Conclusion:

This experiment is a fun way to understand the basic principles of how a thermometer works by seeing firsthand how different liquids expand and contract with temperature changes.

Homemade Thermometer Experiment

Objective

This experiment is meant to help make a functioning homemade thermometer and test its accuracy using scientific principles.

Ingredients

• A clear plastic or glass container
• Water
• Isopropyl Alcohol (Optional)
• Red or blue food coloring
• Clear plastic straw
• Craft Clay
• Ruler or Thermometer for calibration

Procedure

Creating the Thermometer

1. Fill your clear container about 1/4 of the way full with equal parts tap water and isopropyl alcohol.
2. Add a few drops of food coloring. The coloring simply makes changes in temperature easier to see.
3. Put the straw into the container but make sure it doesn't touch the bottom.
4. Use the clay to seal the container where the straw comes out. It should be sealed around the straw so that it can still move up and down, but air can't get in or out of the container.
5. Now you should notice that when you put your hand around the container, the colored water/alcohol mix in the straw begins to move up through the straw.

Calibrating the Thermometer

1. For the thermometer to be useful, it needs to be calibrated. Use a regular thermometer to measure the temperature of the room and then mark it on the straw with a sharpie (or a piece of tape wrapped around the straw).
2. You can additionally place the homemade thermometer in a bath of known temperature to add additional calibration marks.

Using the Thermometer

1. Once it's been calibrated, leave it somewhere and watch the temperature change! The warm and cold air molecules interact with the molecules in the bottle, making them expand and contract which causes the water in the straw to rise and fall.

Conclusion

This experiment should help demonstrate the principle of thermal expansion and contraction. It also offers a firsthand way of monitoring the temperature changes within your own environment.
