Watch a seed germinate with your own seed viewer! Try this experiment at home or in the classroom. It only needs a few inexpensive materials to put together. Then use the Pocket Seed Data Packet to record your findings and analyze the data.
At the same time - help Dr. Biology with the virtual pocket seed experiment. Look for the differences between different packets and compare the results using the Pocket Seed Data Packet.

Brief Pocket Seed View Instructions:
These instructions can get you started with your own pocket seed viewer. For more detailed instructions, download the Pocket Seed Packet.
Soak seeds in a cup of water overnight.
Sprinkle water on the paper towel or napkin so it's wet but not dripping.
Put the wet paper towel and the seeds in the sandwich bag, make sure you can see the seeds without opening the bag.
Seal the bag. Place the bag in a warm safe place away from direct sunlight (so it doesn't get too hot). Check it several times a day, open it for a few seconds to give the seeds air. Then seal it to keep the moisture in. If the paper looks dry, open the bag and sprinkle more water, then make sure it's sealed. Soon, you'll see the baby plant start growing and developing!!
One way to keep track of what happens to your seed is to draw it once a day. Make your first drawing of the seed before you soak it.
You can also try another experiment. Prepare one pocket seed viewer following the instructions above. Prepare another with seeds that you didn't soak. When you do the experiment, think like a scientist. Scientists ask themselves questions. Here are some questions you could ask yourself when you do one of these experiments:
Do you think the two kinds of seeds will germinate differently? How will they be different?
After you do one experiment, some other questions may come up. They might be answered by another experiment. Some suggested experiments:
Besides these suggested experiments, try your own. Just remember, test one thing at a time and always prepare a control bag (one that you don't change anything). That way you can compare the two bags to see if you made a difference.

Beans are seeds too that can be watered and will germinate.
