Design a Delayed-Release Tablet
- Identify various physical properties of a polymer
- Collaboratively undertake a design project that meets specific design criteria and constraints
- Optimize a design solution based on iterative testing
In this lesson, students are challenged to design and build a controlled-release tablet, which will be made from different colored bath tablets and a variety of water-soluble plastics. First, they will have to test the properties of each of the different plastic materials. Then their task will be to create a tablet that releases three different colors, each at a pre-determined time after the tablet has been submerged in water. As students design and build their controlled-release tablets, they will realize how the properties of each material affect their results. At the same time, students will get insight and exposure to drug formulation and development procedures.
