What Conditions Are Necessary For the Germination and Growth of Seeds?
Test the conditions for germination of seeds using a control and a single variable or factor to be tested. Have students make predictions before they perform the experiment. Let the students try to design a way to test their hypothesis. Have them make sure, in the design of their experiment, that there is only one variable so if they observe a difference, they know it is because of the tested variable and not because they set up the 2 jars differently. Here are some suggestions. A. Light vs. Dark • Set up 2 jars with 6 seeds each on the gelatin. • Wrap 1 jar in aluminum foil but do not cover the lid with foil so air can be exchanged. • Do not wrap the other jar. • Place them side by side where they will have a warm temperature and indirect sunlight. • Check them each day to compare how and when they germinate. Make a chart to write in the daily observations or draw a picture. Radishes (and most of the other seeds listed) germinatein less than 24 hours so they will get results very quic
