AbstractGermination is the process by which a seed emerges from the seed coat. Many different variables can effect the process of germination. Try to sprout seeds from different species of plant to see if different species vary in germination time. Are weeds faster germinators than vegetables? Try measuring seeds and then germinating them to see if big seeds sprout at a different rate than small seeds. Try sprouting seeds in different environments to test the effect of different environmental variables on seed germination. Try testing variables like temperature, soil acidity, water content, light or the presence of insects, worms or other plants. You can also cut open seeds to learn about the parts of a seed. By counting the number of cotyledons, you can learn to classify plants as monocots (with one cotyledon) or dicots (with 2 cotyledons).
