## Lukes science project Presentation Transcript

• By Luke
• Insulation By Luke
• Question What is the most effective form of house insulation that saves energy?
• Hypothesis I think that the Pink Batts insulation will keep most of the warmth in the container because it is used to insulate houses.
• Variables Independent variable- Type of insulation-Pink Batts-Tin Foil- Sponge. Dependent variable – Temperature Controlled variable-Type of container.-Time taken between temperature measurements.-Same type of thermometer.
• Equipment 4 ice Cream containers. 200ml of boiling water per ice-cream container. 200ml of cold water per ice-cream container. 4 thermometers. 1 stopwatch. Sponge (enough to cover ice-cream container) 2 layers of tin foil (enough to cover ice-cream container) Pink Batts (enough to cover ice-cream container) PVA Glue
• Procedure 1. Drill a thermometer size hole in the top of all the containers. 3. Put the insulation on the top of the lid and around it. 2. Fill all the containers with 200ml of hot water. 5. Put the thermometer in the hole. 6. Record temperature after every minute that passes. 8.Then repeat with cold water.

• Cold Water Graph 9
• Conclusion During my experiment I found out that Pink Batts is the best form of insulation because it kept in the most heat with hot water and kept the cold water the same temperature. It was interesting to ﬁnd that my control experiment with no insulation was the second most effective in keeping the cold water cool.
• Application This experiment helped me understand why we do have insulation in our houses especially during the cold winter in New Zealand.
