Observing the Development of Drosophila in Apple Juice Agar

Nearly all students have seen pregnant women and may have questions about human development. Intended for secondary students with mild to moderate mental disabilities, this lesson plan defines the process of pregnancy  in a...

In only nine months, a small group of cells grows into a fully developed baby. Pupils learn about the development of an embryo to a fetus to a baby. They identify each step of weekly development. Young scientists look at ultrasounds to...

How do rockets fly? Teams design, build, and launch a rocket made from a two-liter bottle to explore forces on a rocket such as Newton's Laws of Motion.  During the design phase, young engineers draw a diagram of their rocket and...

Can scientists really predict genetic outcomes or are they simply making a lucky guess? Scholars first learn about Gregor Mendel and how to make Punnett squares. Then they extract DNA from a strawberry in a lab with included conclusion...

The development of regulatory genes and the evolution of genes is the focus of a video that shows viewers how closely related we are to not only chimps but to other organisms as well. 

Insects developed wings and the ability to fly earlier than any other animal—when exactly did that happen? Scientists know this fact but struggle to explain when insect wings developed and how this entirely new structure appeared. PBS...

How many hours should be in a day? One species of drosophila naturally prefers a 24.5 hour day, while another strongly prefers a 19-hour day. An animation and graph share data from each of these species when exposed to the typical light...

Students observe obscertainers through indirect observations and make hypotheses about the internal wall structures of the containers. In this indirect observation lesson plan, students make observations of 4 obscertainers with a steel...

When biologists installed cameras in Gorongosa National Park, they ended up viewing a lot more than the lions they were trying to help! Young ecologists observe one of Africa's most beautiful savanna regions with interactive trail camera...

Students examine force and conduct activities that model parachutes and helicopters.  For this airplanes lesson students identify the forces that make airplanes fly higher and land.
