Have you ever wondered how we measure temperature? Whether it’s a chilly winter day or a warm summer afternoon, thermometers are essential tools that tell us about the temperature around us. In this story, we’ll embark on a science adventure to create our own thermometer! Get ready to learn about temperature, liquids, and the science behind how a thermometer works.
Temperature is a measure of how hot or cold something is. We use it in our daily lives to know how to dress, what activities to plan, and even how to cook! The most common units for measuring temperature are degrees Celsius (°C) and degrees Fahrenheit (°F). In Canada, we generally use the Celsius scale. On this scale, water freezes at 0°C and boils at 100°C.
But how does a thermometer actually work? A thermometer measures temperature by using a liquid that expands and contracts with temperature changes.
When a liquid is heated, its molecules move faster and spread further apart. This causes the liquid to expand and rise in the tube of the thermometer. Conversely, when the liquid cools, the molecules slow down and come closer together, causing the liquid to contract and fall. This movement is what we read on the thermometer scale!
Before we create our thermometer, let’s gather the materials we need. Here’s what you’ll require:
Now that we have our materials, let's make our thermometer!
First, take your clear plastic bottle and remove the cap. It’s important that the bottle is clean and dry, so rinse it out if necessary.
Pour water into the bottle until it’s about one-quarter full. If you want to make your thermometer more fun, add a few drops of food coloring to the water. This will help you see the liquid level more easily.
Take the straw and place it upright in the opening of the bottle. Ensure that one end of the straw is submerged in the water, but don’t let it touch the bottom of the bottle. You want the water to rise and fall within the straw.
Use modelling clay or a rubber stopper to seal around the straw and the opening of the bottle. This will make sure that the air inside the bottle is trapped, which is essential for the thermometer to work properly.
Now, let’s calibrate our thermometer! Place the bottle in a bowl of ice water (for 0°C) and mark the water level in the straw using a pen. Next, place the bottle in a bowl of hot water (for 100°C) and mark the water level again. You can even create additional markings for temperatures in between!
Congratulations! You’ve created your very own thermometer! Now it’s time to test it. Try placing your thermometer in different temperatures around your house or outside. Make a chart of the temperatures you measure.
Creating a thermometer is not just a fun and educational project; it’s a great way to understand the science of temperature. By seeing how liquids expand and contract, you can appreciate the wonders of the physical world around you.
Now that you’ve made your own thermometer, you can use it to learn more about weather, science experiments, or even kitchen cooking. Remember, science is all around us, waiting for you to explore! Happy experimenting!
