The document summarizes an experiment to determine the best insulating material. The experiment tested newspapers, plastic bags, woolen socks, and silver foil wrapped around bottles of hot water. Temperatures were recorded over 20 minutes. Woolen socks proved to be the best insulator, with the least temperature drop of 9.8属F. Silver foil had the greatest temperature drop of 13.4属F, making it the worst insulator. The experiment showed that different materials have varying abilities to hold heat.

Purpose This investigation is to find out which material is the best insulator. The material that can hold the heat longest.
Materials Used a thermometer 4 glass bottles hot water a piece of newspapers a piece of silver foil woolen socks a plastic bag
Procedure Step 1 Get ready a thermometer and 4 bottles. Step 2 Testing of water for a right temperature Since I can only get a clinical thermometer with readings ranging from 94属F to 108属F, the temperature of the hot water used must be high, above 104属F. To get readings when the temperature drops.
Step 3 wrap the 4 different materials around each bottle with rubber bands. plastic bag woolen socks newspapers silver foil
Step 4 Pour hot water into all the bottles, and make sure the temperature is above 104属F. Step 5 Put in the thermometer into the bottles and record the reading one by one. Step 6 Record the temperature again 5 minutes later. Step 7 Record the temperature again 10 minutes later. Step 8 Record the temperature again 20 minutes later.
Observations Temp. Temperature 5 minutes 10 minutes 20 minutes (属F) later later later at the start Materials Newspapers 106.8属F 103.6 属F 99.6属F 94.7属F Plastic bag 106.6属F 104属F 100.8属F 95.4属F Woolen socks 104.8属F 102属F 99.5属F 95属F Silver foil 107.4属F 102.4属F 98属F 94属F
Conclusions Temp(属F) Difference between the highest and the lowest Temperature dropped Materials temperature (属F) (属F) Newspapers 106.8 -- 94.7 12.1 Plastic bag 106.6 -- 95.4 11.2 Woolen socks 104.8 -- 95 9.8 Silver foil 107.4 -- 94 13.4
1. Can be seen from the table, the temperature of the water bottle wrap with the woolen socks drops slower than others at each recordings. 2. The temperature of the water bottle wrap with silver foil drops faster than others at each recordings. The total temperature drops for woolen socks is the least, its only 9.8 属F So, woolen socks is able to keep heat longer, and it is the best insulator.
Big Idea 1. I have learnt that different materials has different ability to hold heat. 2. So, we must use the right material for different uses. 3. To keep heat, we use woolen, thicker and darker material. But on the other hand, if heat is to let go faster we can use silver foil, thinner or material with lighter color.
