Investigating Thermometers in Science

Over the past week our class has been investigating the tools scientists use. We have discussed how and why scientists use goggles to protect their eyes, balance scales to compare weight, hand lenses to magnify objects, as well as various other tools.

Yesterday the students were each given a thermometer and were asked to observe it by using their five senses.  We then investigated the effects of hot and cold (using a cup of ice and the sun) on thermometers and how to read the thermometer. Today we had a group discussion on how we can use thermometers. We talked about how our moms and dads place a thermometer in our mouths when we are sick. We talked about how outdoor thermometers can help us figure out how to dress in the morning for school. We also talked about how mom and dad sometimes poke a thermometer in the turkey at Thanksgiving to tell if the meat is fully cooked so we don't get sick. At the end of our discussion the children were tasked with answering the essential question, How can we use a thermometer? in their Science Notebooks. At this early stage of kindergarten the children are writing in pictures but they are starting to show beginning stages of labeling words. The student pictures below show amazing detail and how well they grasped the concept of how thermometers can be used, as well as, the general understanding of how hot and cold refer to temperature.



This student shows Farenhiet and Celcius and includes the numbers associated with thermometer. He decided to show how we use a thermometer when we are sick so the smiley face and sad face represent if you are feeling well or feeling sick. His second page shows that the thermometer gets hot when someone is feeling ill and he shows this in the color red indicating hot. Above he is feeling better and no longer needs a thermometer. An amazing understanding of how thermometers work!


This student chose to represent her understanding of thermometers by drawing a picture of herself sick in bed but she also has begun to label her pictures as well. Here she spells thermometer "simo" and bed "bad". She also choose the color red to represent hot for the rise in temperature when you are not feeling well. If you look closely you can see the thermometer sticking out of her mouth. So cute!




Finally, our last student decided to use the outside weather to show her understanding of how we utilize thermometers. On the left hand side of her drawing she shows that is it night time with stars in the sky and the little girl in the picture in her words "was not dressed appropriately and so she is cold". The thermometer numbers are in blue indicating cold and the little girl has a sad face. She also labels "DOK" for cold.  On the right hand side of the page it is day time with the sun shining with the little girl still wearing her pretty little dress. This time, however, she is much happier as the thermometer shows red around it labeled as "toH" showing hot. The middle of the thermometer shows red more than half way up indicating its hot outside. The little girl is smiling and happy. These students have a clear understanding of how and why we use thermometers. What an amazing job!
