Explore the Trottier Observatory and get an introduction to general astronomy. Then, dive deeper into the science of stars 鈥� learn how to measure the light of a variable star, take multiple images of the same star to see how how photon counts vary over time and, finally, study how variable stars are used to estimate the distance to the Andromeda Galaxy.

The Nobel Prize-winning polymerase chain reaction (PCR) technique, used widely in genetic engineering and microbiology, requires knowledge of the double stranded antiparallel structure of DNA and emphasizes the importance of understanding its molecular details. Learn how this technique is used to determine the components in DNA samples, such as in testing for COVID-19.

See how physics and biology work together in experiments designed to stretch single collagen proteins and measure how they respond to force. By manipulating collagen and observing changes to its mechanical properties, physics researchers explore how this affects the body's aging process and susceptibility to disease.

Get familiar with ice penetrating radar, a piece of geophysical field equipment that images a glacier's interior ice and measures its thickness. Learn about the measurements that assess the health of these icy reservoirs and provide information for the computer models used to make glacier change predictions.
