Innovating Science® - STEM INVESTIGATIONS: Make Your Own Liquid Crystal Thermometer
Manufacturer ID - IS3454
Students will learn about acids and bases through a class discussion and then test a dilute acid and dilute base with neutral litmus paper to learn how the paper indicates something is acidic or basic. Once that skill is learned they can move on to test some common items that would be found around their house to determine if they are acids or bases. Optional: Extra litmus paper is included to test more items either from home or around the school building for a greater understanding of acids and bases. The activity contains enough materials for 6 groups of students.
Working in groups, students will determine the working temperature range for each of the four liquid crystal mixtures. As an engineering challenge, the students will then use the information they have gathered to design and construct a thermometer using their liquid crystals. Through this kit, students will gain an understanding of liquid crystals and how they can be used in a variety of everyday technologies. Kit contains enough materials for 8 groups. Teacher's Manual and Student Study Guide copy masters are included.
