UKS2 – Science – Thermal Conductivity

Following on from our science lesson last week, we used the test results that we collected to make predictions and set up our own investigation. Before our investigation, we used our prior knowledge of thermal conductivity to predict which material would let the heat pass through it the quickest, melting the ice cubes.

We then tested the thermal conductivity of four materials (aluminium, fabric, paper and plastic) by using ice cubes and observing each material after 5 minutes, 10 minutes, 15 minutes and 20 minutes. Whilst the experiment was taking place, we discussed our independent variable (the materials), our dependent variable (the state of the ice cubes), and our controlled variables.
