Optimal Insulators: Testing the Best Thermal Barrier

Explore the efficiency of various insulating materials in containing heat using a simple experiment. Place a small beaker within a larger one, insert insulating materials between them, add hot water and a thermometer, then track temperature changes every 2 minutes over 20 minutes. Repeat with different insulators.

  1. Unit2 11.f.21 Heat energy Lesson 4 What is the best insulator? MPW/EQI

  2. Key Question What is the best insulator? You will answer this question in your experiment. MPW/EQI

  3. Experiment • Cling • film • Small • beaker • Hot • water • Thermometer • Large • beaker • Insulating • material MPW/EQI

  4. Method Fill in the gaps using words from the apparatus list. I will put a small beaker inside a largebeaker. I will put some insulating material into the gap between the beakers. I will fill the small beaker with hot water and put a thermometerinto it. I will cover the top of the beaker with cling film. I will write down the temperature and start thestopclock. I will write down the temperature every 2 minutes for 20 minutes. I will repeat the experiment with different insulating material. MPW/EQI
