How can I reuse seed pods for the AeroGarden?
I have the plastic seed pods and I would like to reuse them, but I don’t know what type of growing medium to use. Any suggestions?
Also, I have a few 3″ high tomato seedlings, is there any way to transplant them to the AeroGarden in the seed pods I currently have?

You can reuse the plastic holder but you would probably need to purchase an Aerogarden kit for that purpose. A couple possibilities: http://www.aerogardenstore.com/promotion/index.php?promoName=catalog&pageName=product&viewProduct=0022-00Z or http://www.aerogardenstore.com/promotion/index.php?promoName=catalog&pageName=product&viewProduct=9149-00Z
You may be able to use a piece of rock wool which you may be able to find at a landscape supply company or a nursery or: http://www.amazon.com/Grodan-Rockwool-1-5in-Individually-wrapped/dp/B0002IU8UW
You probably will need to trim them to fit.
I would not recommend moving your tomato to your Aerogarden. It is best to just start tomatoes in it. Also, an Aerogarden is designed to grow the smaller varieties (as far as the plant – not the fruit) so it would need to be a patio type tomato. Instead it would be better to plant your tomatoes in large pots – at least a 5 gallon bucket to a 14″ diameter pot. If you live in a warm enough climate you could plant them outside.

How do I turn my observation in to a science fair question?
We have a dish of wheat grass sprouting. We noticed that every time we water it, a single drop of water goes to the top of every blade of grass. What does it mean? How long does that process take? Does saturation on the growing medium affect this process? And again, what process is really taking place here? Please help me turn this in to a science fair question…this is for my daughter’s 4th grade project.

This may be an indication that your plant is unable to transpire and draw water through its xylem. . When the air is very saturated the plants have trouble because their stomates are open but no water is evaporating. Water is not drawn up through the xylem without transpiration so the dissolved nutrients are stalled en route. At this point some plants have special cells called hydathodes to secrete some water so there can be a small xylem flow. This is guttation but only happens with very wet soil and high humidity.
To ask if this is a response to humidity create a set of terrariums with different levels of humidity. Do one at room temperature just as you have been doing it to be sure the phenomena continue. You will need a hygrometer to measure the daily humidity in each container. Clear plastic sweater box or similar would work well to establish an environment or an old aquarium. Ideally the containers should be the same size to eliminate that as a variable.
Grow your grass at one or two points above and below your normal house humidity.
If the plant is not experiencing high humidity then it may be dew or condensation. The dewpoint of the air is the temperature at which air is saturated with water.
The lower the dew point (reported as a temperature), the drier the air, and vice versa.
