We’ve been collecting data on insulators. We tested air, cotton and steel wool to compare how well each one kept the heat inside the container.
Yesterday we did the plan phase of the scientific method and figured out how to do the lab. Today we’re doing the conduct the lab and collect the data part. Tonight we’ll analyze our data…we have to make a graph showing all three materials and use a key.
Then on Friday, we’ll talk about our results with the whole class and draw a conclusion based on our graphs and the data collection table.
This was a fun lab because we had ice water baths for our cups. We had to keep them under water for 5 minutes and take measurements every 30 seconds using a big stopwatch Mrs. Ratzel had on the SmartBoard. Lots of the desk got wet and lots of people had cold hands.
Dear Leawood Middle School,
We love your class blog! We hope you did not get cold after the experiment! Did it take you a long time to do the experiment? Please tell us the conclusion to the experiment when you respond.
Sincerely,
Melissa and Soledad
Dear Melissa and Soledad,
This is Cassie. Cold Stuff took us a couple of days. We experimented with temperature of differnt itesm like air, steel wool and cotton balls when they are in cold water. Our class thought steel wool was a good insulator because they contained the most amount of heat.
What experiments have you been working on in your class?
Dear Mrs.R’s class,
I love what you did on Cold Stuff Lab. How did you do that and make it so awesome? Where did you get the tools?
Sincerely,
Angelica & Izabell
Dear Lee wood middle school,
It’s fascinating that you looked witch would be a better insulator air,cotton and steel wool.I wonder which one was a better insulter?
Your Friends
nicolas and faith
that was so cool i want to do that one day i am going to do that bye!
i am going to try that one day
