Introduction to Seed Germination
Students explore seed germination. In this life science instructional activity, students start seeds in Petri dishes, then observe which ones germinate and make predictions.

Soil pH Effect on Germination of Specific Weeds
Students collect weed seeds from three varieties of weeds (knapweed, thistle, or toadflax, for example they may choose others in addition to the spotted knapweed.) They sterilize soil for thirty containers, plant seeds in sterile soil,...

From Seed to Plant
Pupils adopt seeds, recording their observations as they draw their seeds, germinate them, and plant their seedlings using the hydroponic method. Students maintain journals recording their germination experiments.

The Effects of Environment on Plant Growth: Selecting Seeds for Survival on a New Planet
Fifth graders conduct experiments to compare seed germination and plant growth rates. They construct a hydroponic plant unit and a lighthouse. They care for the plants for a month and collect data for graphs. They write a report.

Estimation of Population Growth By Counting Offspring: Seed Multiplication
Students calculate the reproductive rate of a plant that creates multi seed fruits. They graph exponential growth and the complete a series of questions that help them infer that natural selection processes are at work in this population.

Growing Plants
Students design and create a suitable vacuum formed shape made from MDF in which they may grow some mustard seeds. They then experiment with different conditions that it takes for seeds to germinate, setting out one set of seeds on dry...
