Do you know how plants get the energy they need to grow and reproduce? They do not eat like humans and animals do; they make their own food with a process called photosynthesis. During photosynthesis, plants convert light, water, and carbon dioxide from the air into oxygen and sugars. In this activity, you will be able to observe the oxygen production in leaves by doing a floating leaf disk experiment. You can also find out how quickly plants produce oxygen, and what variables affect… Read more

Did you know that the seaweed you've seen in the ocean or even eaten as a snack is inspiring innovators to imagine new materials? Large brown algae, like kelp, contains polymers—long chains of molecules—that are more environmentally friendly than the ones in most plastics. These natural polymers (alginates) could eventually be used to create sustainable everyday objects. Try your hand at using a bit of chemistry to turn biodegradable polymers from algae into your own custom… Read more

Ever wondered how DNA, the genetic blueprint of a life-form, can encode and pass on the information on how to grow and maintain that life-form? Just like a cookbook contains a complete recipe for a dish, DNA stores the recipe for the life of an organism. Although each human has a unique DNA sequence, the DNA in all of us is about 99.9% identical! In this activity, you will use pieces of candy to make a model for a short section of DNA—enough to get a sense of what DNA is like and how it… Read more
