The claim-testing gang find themselves in a bind and conduct their own experiment to show how agriculture leads to more complex societies.

What does farming have to do with invention and innovation? Patricia Russac explores how farming was a major innovation leading to the civilization we know today. [3:59]

This collection of images shows several types of plant seeds, each with a different mechanism for dispersing from the parent plant.

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...

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...

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...

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...

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,...

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...

In this ZOOMSci experiment, you're invited to walk through a grassy or weedy field in your stocking feet, then plant a sock and see what grows.

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.

What do plants need? Students examine the effects of light and air on green plants, learning the processes of photosynthesis and transpiration. Student teams plant seeds, placing some in sunlight and others in darkness. They make...

Jethro Tull (1674-1741) invented a machine that helped to increase the harvest yield by planting seeds in straight lines, a vast improvement over sowing by hand that led to greater crop yields.

This simple lesson plan is designed to help young young scholars be aware of how seeds sprout, and that seeds grow into plants.

In this lesson, students will plant seeds, record the changes, and connect the relationship of seeds to plants. This lesson should be taught at the beginning of plant unit.This lesson plan was created as a result of the Girls Engaged in...

Nikki is learning about plant seed dispersal methods. Join in and learn how this is important to plant reproduction.

The students will be collecting, germinating and planting seeds to show the process of plant growth. The students will be recording the information in their science journal. In addition, the students will be observing the water cycle as...

Students will communicate in oral, artistic, written and nonverbal form as they study seeds and their growth. Students will plant seeds, make observations about the seeds' growth, and report their observations to peers .

Help Detective Le Plant discover how a seed grows into a plant. Students will learn to describe a seed's structure and what's needed for seed growth.

How are prairie plants able to survive fires? This site will explain how seed germination takes place after a prairie fire.

This site has excellent resources for teaching students about plants. It has a guide to scientific investigation and a glossary of plant terms. There are three lessons that each include a slideshow on the parts of a plant, the needs of...

Students will observe the parts of a seed, and identify how the different parts of the seed help a plant germinate.

A good description of the growth and changes in plants from the seed through the adult plant. College level discussion that includes the chemicals involved in the regulation of plant growth.

A webpage for a course on plant biology for non-science majors. The course covers how plants function, diversity among plants, and the roles of plants in the environment. Site includes lectures, a plant project, and a sample exam.
