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...

Can a coral cure cancer? Take seventh and eighth grade science sleuths to the underwater drugstore for an investigation into emerging pharmaceutical research. The fifth installment in a series of six has classmates research the wealth of...

Students research plant growth. In this plant growth lesson plan, students explore the needs of plants. Students compare and contrast grass and broadleaf plants and grow a miniature lawn in a cup of soil. Resources are provided.

First graders evaluate what it takes for a seed to become a plant. They brainstorm what they know, discuss what they want to know and interact with a Plant WebQuest that indicates what they have learned. They also examine how we get the...

How does nature select some adaptations over others? Scholars experiment picking up seeds with two different types of tools simulating beaks. After practicing, they experience a drought where one type of seed suddenly isn't available....

The density of the huge planet of Saturn is 0.7 g/cm3, which means it could float in water! In the second part of 22, science pupils explore the size and order of the planets. They then calculate weight and/or gravity and density of...

Teens experience natural selection firsthand (or first beak) in an activity that has them act as finches foraging for food. Using different household items  to act as different beak styles, your little finches will collect as much...

Get your class outside to observe their surroundings with a lesson highlighting weather patterns and seasonal changes. First, learners take a weather walk to survey how the weather affects animals, people, plants, and trees during...

Plant growth experiments offer rich, cross-curricular learning opportunities that can really excite and engage young learners. In this series, children work in pairs planting, measuring, and comparing the height of bean plants in order...

Learners determine what part of a plant they are eating when they eat different fruits and vegetables.

Students use a plastic sandwich bag containing a damp paper towel taped to a window as a model system to observe the germination and early growth of radish seeds. They are challenged to pose a question about seed germination and growth...

Students explore fruits and vegetables. In this fruits and vegetables lesson, students study traits of various fruits, vegetables and seeds. Students rename fruits, vegetables and seeds.

Students explore the physical properties of sand, soil, and rocks and sort, classify, compare, and contrast the materials found in the soil. The differences between the living and non-living parts of the soil is discussed.

Students examine the clinical effects of environmental toxicants on living organisms by collecting and analyzing scientific data and identifying ways of detection and diagnosis.
