Effect of Light on Seed Germination

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...

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...

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...

When exploring Mars, spacecrafts are exposed to 5-11 times more sunlight than when near Earth. Groups of pupils complete a hands-on activity to explore how distance and angle of the sun affect temperature. Through discussions, they then...

Gummy bears are tasty, but did you know they are also used to determine color and light properties? Use the activity as a way to demonstrate light absorption, light reflection, and refraction with high schooler. Pupils conduct small...

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...

Watch your classes grow during as they experiment with science and mathematics! Learners collect data on percent of seed germination over a two-week period. They graph their results and create a report analyzing their findings.

Learners 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 which...
