Experiment with Liquid Crystals
Liquid crystals are an example of self-assembled molecules that are sensitive to external factors, such as temperature, and that change their assembly as a consequence of variations in these factors. In this experiment you will see how some liquid crystals change colour as their temperature is changed! You will find the information you need to carry out the experiment in the documents below. You can also watch the information video available below.
