In this activity, students will set up electrochemical cells, with each group using a different combination of materials for the anode and the cathode of the cell. Students will also compare two different styles of cell, one using a salt bridge and one using a semi-permeable membrane. After determining the voltage output of their cells and comparing their values to the rest of the class, students will be challenged to design an electrochemical cell that can run a small motor.

There are certain characteristics of all living things that the scientific community uses to judge whether something is alive. On first observation, yeast does not look like a typical living thing. In this activity, students will hypothesize about yeast and then test to see if their hypothesis is correct. Using this information, they will be able to come to a conclusion to the question of whether yeast is alive. Kit contains enough materials for 15 groups.

Liquid crystals have an ordered structure like a solid, but are also fluid like a liquid. The molecular-level structure of a liquid crystal can be affected by changes in its environment, such as electric field or temperature, which can lead to changes in its macroscopic properties, such as color. In this experiment, students mix three chemicals in different ratios to form four different liquid crystal mixtures that are sensitive to temperature.\u003c\/p\u003e\n\n\u003cp\u003eWorking 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.

The majority of these products are disposable items, leading to excessive amounts of plastic being discarded into landfills and the oceans. Due to the major threat this poses to the environment, scientists and engineers are developing bioplastics that break down more quickly and produce less harmful byproducts than traditional plastics. In this activity, students will make samples of different bioplastics to study how their composition affects their physical properties. They will then use what they have learned to create a bioplastic that could be used to replace the PET plastic in disposable water bottles. Additionally, students will design an experiment to compare the biodegradability of their bioplastic samples to a traditional plastic. Kit contains enough materials for 15 groups.
