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.
