Seed Dispersal in Tropical Forests
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...

Photosynthesis and Cellular Respiration
How does energy from the sun make plants grow? Scholars move step by step through the processes that promote plant propagation during a detailed lesson. The resource illustrates ADP production and hydrolysis, then allows learners to...
It's About Time
Photosynthesis, Respiration, and the Carbon Cycle
Provide your class with the opportunity to view our carbon cycle close up. Young scientists research the cycle of oxygen as it completes the tasks of photosynthesis and respiration. They explore the importance of carbon in an ecosystem...

Genetic Engineering Challenge – How Can Scientists Develop a Type of Rice That Could Prevent Vitamin A Deficiency?
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: Project Ides: Propagate Plants Without Using Seeds!
This plant biology science fair project that explores factors involved in successful propagation of plants using plant division instead of seeds. The Science Buddies project ideas are set up consistently beginning with an abstract,...

Science Buddies: Planting Size vs. Depth
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
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: Cryopreservation: Freezing Plant Tissues
Cryopreservation-storing seeds in ultra-cold liquid nitrogen-is one method for maintaining plant genetic stocks in seed banks. The purpose of this project is to observe the characteristics and outcomes of cryogenically frozen seedlings...

Science Buddies: Radiant Radish Seeds
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?
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: Hydrogen Peroxide on Plant Root Cuttings & Seed Germination
Hydrogen peroxide (often used as a disinfectant) has also been approved for use in pesticides. This science fair project investigates whether hydrogen peroxide has any effects on seed germination or on roots of plant cuttings.

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

Gardening & Horticulture in Denver: Gardening With Children
The section on plant projects for kids has lots of hands-on ideas for studying plant biology. Activities are included for stages from seed germination to growth. Geared more to the younger student.
