Effect of Light on Seed Germination

Here's a five-star lesson plan in which inquisitors conduct sophisticated experimentation with cellular respiration in plant seeds. Placing seeds in a closed system they measure the amount carbon dioxide produced and relate it to...

Illuminate your physics class with this examination of a photovoltaic cell. Teach the structure and operation of the device using a diagram. Then make a human-powered, larger-than-life sized model of a PV cell. Learners become electrons...

Many types of cancer treatments now depend on nanotechnology—a big "little" discovery. Scholars begin by removing "malignant" tissue from simulated brains, one using fluorescent markers thanks to nanotechnology and one without. This...

Students investigate the effects of acid rain on seed germination. In this acid rain lesson plan, students design an experiment to study the effects of sulfuric acid on seeds. Students observe their control seeds and acid treated seeds...

As the title implies, here is a collection of typical photoelectric effect problems that physics learners need to be able to solve. They determine the amount of energy of a photon, the photons produced per second, the frequency required...

At minimum, beginning botanists learn the terminology used when discussion seed germination. This set of slides lists basic seed parts, requirements for germination, steps of the process, and then it differentiates between monocot and...

Surely you must appreciate when a PowerPoint comes complete with teachers' notes. This brief, but beautiful presentation provides narration for you to use with each slide. The topic is plant propagation from seed. Photos, diagrams, and...

One of the reasons plants found success on land relates to seed development. Scholars learn about many different forms of seeds and how they changed over time. It describes the structure and function of many different types of seeds in...

Breathe some new life into charcoal. Scholars use biochar to improve soil fertility. They test the effectiveness of this addition by conducting an experiment with soil having 0%, 2%, and 4% biochar.

High schoolers use an on line website to simulate the effects of light intensity and wavelength on photosynthesis. In this photosynthesis lesson plan, students determine how wavelength of light and intensity of light affect the rate at...
