Topic- Material – Thermal Conductor and Insulator
This week in science we will be carrying an experiment to compare and group together everyday materials based on their conductivity of heat.
Safety- Only carry out the experiment with an adult.
Watch the video below on heat and insulation.
Research the meaning of these words:
1. Thermal Conductor
2. Thermal Insulator
Experiment- Comparative test – Which cups let through the most heat?
Select a variety of cups made from different materials. For example: plastic, paper, ceramic, enamel and glass. Use what you have at home.
Fill the cups with warm water (no warmer than 60 degrees Celsius). This step is to be done by an adult.
Use a thermometer to measure the temperature of the water in each of the cups over time (10 minutes intervals).
Recording- Draw your own line graph; a line for each of the cups. Your line graph should show temperature and time on the axis.
Answer the questions you started off with - Which cups let through the most heat?
