Teacher’s guide This is a step-by-step timetable for the Nobel Prize Lesson about a 2018 Nobel Prize. This lesson package consists of four parts: a slide show with a speaker’s manuscript for the teacher, a student worksheet, two short videos and this teacher’s guide. The lesson is designed to take 45 minutes. Teacher’s_guide (PDF file 63K) […] Continue reading
UV cameras expose a hidden world and reveal the incompleteness of our perception. In summary, ultraviolet light interacts differently with matter for a number of reasons: 1. Some pigments selectively absorb UV so they may appear white in the visible but dark in the UV. Continue reading
MIT Media Lab researchers have created a new imaging system that can acquire visual data at a rate of one trillion frames per second. That’s fast enough to produce a slow-motion video of light traveling through objects. Continue reading
With the help of a specialist doctor and an opera singer, Sophie Scott investigates how the different parts of the voice box come together to create the human voice. Continue reading

I try to build a camera in the most absurd way I could think of: by starting with a penny. Continue reading
Food availability is limited in some regions of the world for many reasons, such as access to natural resources (sunlight, space, water, soil). Due to urbanization, access to fresh fruit and vegetables in urban areas is becoming more limited. How do we feed our communities and ensure food sustainably in an urban landscape?
In this inquiry-based activity, students will design and build a model of a greenhouse using mirrors and/or lenses that can be used to grow food all year. They will use their knowledge of optics to make their greenhouse more efficient (i.e., optimal temperature for plant growth).
*This activity can be used as a Course Culminating Activity as it allows students to demonstrate their proficiency in the following areas:
Cells and Tissues (plants and plant growth)
Chemical Reactions (pH of soil and acid-base reactions)
Light and Optics (reflection and refraction through mirrors and lenses)
Climate Change (influence of CO2 and temperature upon growth of plants)
How can we use optics to maximize food production?
Reflection, refraction, pH, CO2, temperature, mirrors, lenses, plant growth

In this demonstration, students observe what happens to activated glow sticks when they are submerged in water at three different temperatures: cold, room temperature, and hot. Continue reading
I first saw a Schlieren imaging setup around ten years ago in Melbourne. I was immediately fascinated by the way I could see the warm air coming off my hand. I hadn’t expected the currents to be moving that fast or to be so visible. Continue reading
