Innovating Science™ Biomaterials To Make Your Own Contact Lenses

Description

Engineers play an integral role in finding a ratio of materials to maximize the desired properties and decrease the negative effects of other properties. Students will engineer a lens using 2 different materials

• Determine the correct material and the concentration that has similar properties as a contact lens, while discovering the correct optical properties, tensile strength and hydrophobicity.
• A hydrogel is a polymer like plastic, which has favorable optical properties and favorable flexibility/strength but like paper and glasses/ceramics is hydrophilic, which is necessary for a contact lens to function properly.
• Aligned to the Next Generation Science Standards (NGSS)
• Disciplinary Core Ideas: ETS1.A; ETS1.B; ETS1.C; PS1.A
• Performance Expectations: MS-ETS1-1; MS- ETS1-3; MS- ETS1-4; HS-PS1-3; HS-ETS1-2
