Effect of Light on Seed Germination

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...

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...

Enough talk about the Greenhouse Effect—let's actually look at it! Junior climatologists engage in a simple thermodynamics experiment on a cold winter's day to examine global warming. The activity simulates rising carbon dioxide levels...

Optometry jokes just get cornea and cornea. Young scientists use a lens and light to create and measure focal points on both a note card and the wall. They then complete a reading passage and questions as homework. 

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.

The greenhouse effect warms up earth enough so it can support life, but if it heats up too much, life won't be able to survive. An interactive presentation covers the greenhouse effect, the carbon cycle, climate forcing, and climate...

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.

Students develop experiments testing the effects of an acidic solution on seed germination. They place radish seeds in petri dishes and water them with different PH solutions. Through Internet connections, they exchange data with...

Careful, that light bulb is hot! Compare heat and light energy using a simple light bulb. The exercise addresses energy conservation and presents actual calculations to determine the most cost-effective light bulb.

Students explore the components of the seed germination process, set up a variety of seed germinating environments, and monitor the growth patterns of the seedlings. Measurements are recorded and graphed.
