During the holidays, we often find ourselves surrounded by a wide variety of taste sensations. Have you ever wondered how well we sense different tastes? People are generally able to discern five basic tastes: sweet, umami (also known as savory), salty, sour and bitter. Is it easier to detect some of these flavors at low concentrations compared to others? In this science activity, you (and possibly your friends and/or family) will find out by exploring your taste thresholds for sweetness,… Read more

Take a deep breath: freshly baked cookies, smoke from a wood fire, or a rose—your nose is an amazing smell detector! Your sense of smell can not only identify a huge variety of odors, but it is also incredibly sensitive. Think about how easily you can detect if someone in your neighborhood has a barbecue just by smelling the hints of smoke from the grill far away. How strong or weak you perceive an odor depends on its concentration. What do you think is the lowest concentration of a… Read more

Maybe you have heard people telling you not to eat potato chips because they are bad for you and contain too much fat. But is this really true? Do this activity and find out by making the fats in potato chips visible. Read more

Ahchoo! Got that stuffy nose and I-can't-breathe kind of cold? Those sniffles and clogged sinuses are bad enough, but why does it also seem everything tastes so bland and flavorless when we are sick? Is there really truth to the idea that smell is a key part of taste? Gather up a few volunteers, hit the kitchen, and try this experiment to find out. Read more

Tilt-A-Whirls, Merry-Go-Rounds, Spinning Tea Cups...does just the thought of them make you dizzy? Why should something so fun make our heads spin so long even after the ride has stopped? Learn about spins, turns, and the mixed signals that fire in our brains when the sensation of dizziness takes over. Weak stomachs, beware. This project has tests that will make your head spin!

Taylor Swift famously got in shape for her three-hour-long Eras Tour concerts by singing all 40+ songs...while running on a treadmill! Have you ever tried running while singing at the top of your lungs? How hard do you think it is? In this science project you will measure the impact talking and singing have on a group of volunteer runners. Is anyone in better shape than Taylor Swift? Read more

Scientific Method
Over time, viruses evolve. Their evolution is influenced by both neutral drift, the natural mutation rate of the virus, and selective pressure from the hosts' immune systems. Scientists study a virus's genomic evolution—the changes at the nucleotide and amino acid level—to better understand how the virus is spreading and the clinical implications. You can use public databases and tools to do the same type of tracking and analysis of COVID-19 that scientists around the world do. … Read more
