Seed Dispersal in Tropical Forests

For Teachers 9th - 12th Standards
How do seeds get around? It's not like plants can control seed dispersal—or can they? Dig deeper into the amazing mechanisms of seed dispersal observed in tropical plants through interactives, a video, and plenty of hands-on data...

Genetic Engineering Challenge – How Can Scientists Develop a Type of Rice That Could Prevent Vitamin A Deficiency?

For Teachers 9th - 12th Standards
Brown rice contains vitamins B and E, while white rice lasts longer in storage. The availability of rice around the world makes it a great candidate for genetic engineering. Scholars apply their knowledge of genetic engineering to solve...

Science Buddies: Planting Size vs. Depth

For Students 6th - 8th
Plants have evolved many clever mechanisms to ensure that their seeds will wait for appropriate conditions before sprouting. Some may only germinate after a fire, others only after going through a cold spell. This project explores one...

Science Buddies: Gone With the Wind: An Experiment on Seed and Fruit Dispersal

For Students 3rd - 5th
If you have ever made a wish and blown the fluff of a dandelion, you have witnessed how some plants are adapted to spreading their seeds using the wind. The tiny, furry parachute allows the seeds to be picked up by the wind and to be...

Science Buddies: Radiant Radish Seeds

For Students 3rd - 5th
We all know that plants need sunlight and water to grow big and tall. But did you know that inside seeds are baby plants, and that the fragile baby plant inside the seed needs to be protected? If you've ever had a sunburn, you also know...

Science Buddies: How Many Seeds Do Different Types of Fruit Produce?

For Students 3rd - 5th
Do you like your strawberry jelly with or without the seeds? Are you glad to have a seed-free watermelon, or do you enjoy spitting the seeds into the garden? You might not like to find seeds in your fruit, but fruit is nature's way of...

Science Buddies: How Do Roots Grow When the Direction of Gravity Changes?

For Students 3rd - 8th
You might not know it, but plants are able to sense their environment and actually respond appropriately. One of the key parameters that every plant must respond to is the direction of gravity: stems go up (opposite to the pull of...
