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.
Task 2
Research the meaning of these words:
1. Thermal Conductor
2. Thermal Insulator
Experiment- Comparative test – Which cups let through the most heat?
Task 3
Step 1
Select a variety of cups made from different materials. For example: plastic, paper, ceramic, enamel and glass. Use what you have at home.
Step 2
Fill the cups with warm water (no warmer than 60 degrees Celsius). This step is to be done by an adult.
Step 3
Use a thermometer to measure the temperature of the water in each of the cups over time (10 minutes intervals).
Step 4
Recording- Draw your own line graph; a line for each of the cups. Your line graph should show temperature and time on the axis.
Step 5
Answer the questions you started off with - Which cups let through the most heat?
