The scientific method keeps you from believing only what you want to believe — it expands your mind. The lesson introduces the eight steps in the scientific process and how to design an experiment to biology scholars. Live insects...

Ever wondered what motivates a roundworm? Introduce your biology class to C. elegans, a non-parasitic model organism that can help them understand behavioral stimuli. Paired pupils design an experiment to test the worm's reaction to...

Have you ever wondered what roundworms are like? Or what they don't like? Explore the sensory preferences of C. elegans through this controlled chemotaxis experiment. Biology class members brainstorm what substances might attract—or...

Lead your biology class on a cell-sized adventure! Emerging scientists construct models of prokaryotes, then design an experiment to properly grow a bacterial culture. They conclude the activity by viewing the culture under a microscope....

Young scientists roll up their sleeves and get a little dirty in this three-day earth science investigation. Following the scientific method, children monitor the growth of algae in pond water samples in order to determine...

Can scientists increase the rate of photosynthesis to help clean the air? Scholars complete an experiment determining net photosynthesis. Then, they apply knowledge from the activity to design their own investigations of the factors that...

Demonstrate the ratio of surface area to volume in your high school class by using phenolphthalein, gelatin, and an onion. Intrigue the class by leading a discussion on osmosis and diffusion, then making "scientific jello." Participants...

Who doesn't love gold and silver? Brine shrimp, that's who! Learners conduct an experimental lesson to monitor the toxicity of gold and silver nanoparticles on brine shrimp. They synthesize solutions to expose the brine shrimp to and...

Certain materials do not always maintain the same physical properties when they exist in the nanoscale. Help your classes to explore this idea through an experimental lesson plan. Scholars use spectroscopy with samples of...

Merge chemistry with environmental science to study biodegradable materials. An engaging activity allows learners to experiment with different resin concentrations and composites. Through experimental tests, scholars test their creations...

Join the fight against bacteria. An open investigation shows pupils different aspects of antimicrobial substances, such as disinfectants, deodorants, or plant oils. They design and conduct their own experiments on the effectiveness of...

Scholars harness the power of microbes with an engaging activity that uses yeast to break down sugar in water. Multiple setups of the same experiment lets learners determine which temperature results in the fastest rate of...

Does the early bird really get the worm? If so, which color of worm does it prefer? In an exciting and easy week-long field investigation, young field biologists set up a one square meter feeding area for birds. If you have a webcam,...

How effective are cells at repairing UV damage? An inquiry-based lesson has learners experiment with organism by exposing them to various levels of UV light and then examining their DNA after a period of time. Pupils test different...
