The Best Seeds for Science Projects

Updated February 21, 2017

The best seeds for science projects are those that germinate quickly and grow well in light or even shade. It really depends on the project. Fast-growing seeds are a good choice because the project won't take very long to complete. These seeds grow well in poorer conditions and are good for placing in varying conditions according to the project's objective.


Radish seeds have the fastest germination period. It takes only two to 10 days for a radish to germinate and only 20 to 30 days to mature. They can tolerate different soil conditions and can handle the cold. Since the radish has shallow roots, they can be grown in small containers, which are perfect for science projects. The radish is a good beginner plant for kids.


Bean seeds are a common science-project choice. Many different varieties can be used, such as the kidney bean, lima bean, mung bean and soybean. All of them germinate in as little as three to seven days. Bean plants love direct light and are a good choice for science experiments about the affect of light on plants. They can handle poor conditions fairly well.


Sunflower seeds can be a good science-project choice for older students, such as those in middle school. These seeds take five to 10 days to germinate and over a month to mature. They can be planted in small pots for the experiment and then planted outdoors once the project is finished. Sunflower seeds always grow so they are facing east where the sun rises.


There are many varieties of squash, including the pumpkin, that can be used for science projects. They generally germinate in five to 15 days. They need full sun to grow well and require rich soil. Squash seeds can be used for experiments about soil conditions. They also need to be watered regularly because irregular watering of squash seeds can lead to early ripening. That could be another science-project idea.


Sweetcorn can take more than a week to germinate, but it still has good uses in science projects. The vegetable can be grown in large pots. Sweetcorn thrives in heat and can survive drought conditions by using the moisture found deep in the ground. It does not like the cold. A science project can be done on how temperature affects the growth of sweetcorn.
