Cookie Lab

Put your aprons on and join us for an hour of science in the kitchen! In this class we will learn the similarities between the recipe and the scientific method. Attendees are able to enter the cookie lab to bake, dissect, and taste how one little recipe adjustment can make a big difference to the quality of a cookie. In this lab, participants will form a hypothesis, follow a procedure and then "analyze" the results using some of the best scientific instruments humans have – our taste buds and noses!

Recommended for ages 8 and up. General Admission is not included in the price of the ticket.

Time: 10AM - 12PM

Bug Appetit!

Crickets, mealworms, and beetles, oh MY! Did you know that almost a third of the world’s population eats insects as part of their daily diet.  The World Health Organization recently promoted the eating of insects, also known as entomophagy in the science world, as a more sustainable source of protein. Come learn all about the environmental and nutritional advantages of eating insects. We’ll try a variety of different bugs and even cook with them to create a bug buffet!
