Tick-Tock: Biological Clock

Take your time with this lesson plan. Junior engineers read about different types of clocks and then work together to build a pendulum time-keeper. There are no hints as to how they might go about accomplishing this complex task, so you...

Students complete experiments to learn about their internal body clocks and physiological activities. In this internal body science lesson, students read "Body Clock Investigations" and complete a body temperature investigation.

Offering a comprehensive overview of symbiotic relationships, this presentation would be a great way to introduce or review material covered in a biology class. There are definitions, examples, and a quiz on the meaning of parasitism,...

All types of organisms sync behaviors using biological clocks. But how do those biological clocks work? It turns out the moon is in control! Part of a larger series exploring biology, the video presents an exploration of this phenomenon...

Animals don't read clocks, so how do they know when it is time for eating, sleeping, and other cyclical needs? Viewers watch an animation of the genes and the molecular clocks inside most mammals. They compare the difference in wild...

Learners research water clocks online, investigate how water clocks work, and construct water clock that will keep time accurately for at least two hours without human intervention.

What does the EM stand for in terms of physics? Learners are introduced to the EM, Einstein's relativity, light years, and the speed of light in terms of relativity. Good examples and concrete visuals guide viewers through the complex...

Third graders investigate the events of geological time using a chart called a "Clock of Eras". In this geological events lesson plan, 3rd graders compare a standard clock to a geological clock. In addition, students consider periods...

Students explore, analyze and study various patterns of change in the context of biological/internal clocks. They observe the opening and closing of a Morning Glory flower as they are introduced to the concept of biological clocks in a...
