Even if you’ve never heard of chromatography, you have probably seen it in action. Chromatography is a process of separating a mixture of chemicals into various parts. It can be used in forensics and for testing food, beverages, and prescription drugs. In this at-home experiment, we use water, markers, and paper towel strips to better… Continue reading
While we are closed, the plants and animals at the Science Center still need to be cared for. That includes the honey bees in the outdoor GROW area. Follow along as Hannah and Maddie move an entire honey bee colony to their new home. Connect with curiosity!
Have you ever seen Elephant Toothpaste? In this at-home chemistry demonstration, we return to a classic. Watch as Lauren uses household items to create a substance that foams, bubbles, and changes temperature. Connect with curiosity!
Did you know that Axolotls, Western Lesser Sirens, and African Clawed Frogs are all carnivores? Go behind-the-scenes with Charlie in our Life Science Lab to find out how these amphibians hunt for prey while he feeds them their favorite snack. Connect with curiosity!
In this at-home activity, learn to utilize the forces of capillary action to make a planter at home that will water itself. Plants use capillary action to draw water from the ground up into their roots and stems in order to survive. Capillary action is able to work against gravity because the forces that keep… Continue reading
