Animals and plants develop relationships and rely on each other to survive. Pupils learn more about symbiosis through a video, a hands-on matching activity, and a game. They differentiate and describe each type on a written evaluation.

Blow the minds of young scientists with this collection of inquiry-based investigations. Based on a series of eight videos, these "hands-on, minds-on" science lessons engage young learners in exploring a wide range of topics...

It's a classification sensation! Demystify why we classify using an inquiry activity that helps your class sort things out. Groups begin by classifying a variety of shoes before they research organisms and design their own dichotomous...

What does the future of energy look like? Junior engineers collaborate to discover a solution to the global energy crisis during a very hands-on lesson. The unit focuses on learning through collaboration to develop a deep understanding...

Celebrate the arrival of spring with this fun primary grade science unit. Engaging young scientists with a variety of hands-on activities and inquiry-based investigations, these lessons are a great way to teach children about...

First graders get out and explore two different habitats to examine how each one meets the needs of the plants and animals that dwell there. They discuss what they've learned about animal habitats as they explore the outdoor environment....

Here's a five-star lesson plan in which inquisitors conduct sophisticated experimentation with cellular respiration in plant seeds. Placing seeds in a closed system they measure the amount carbon dioxide produced and relate it to...

Two sequential parts to this lesson introduce your class to the electromagnetic spectrum, the ability to absorb radiant energy, and the pigments in leaves that are responsible for collecting sunlight to be used in the photosynthetic...

When life gives you mold, make penicillin. Scholars design an inquiry experiment to determine what causes rotting and mold growth. It also covers decomposers and the important role they play for other living things. 

Eukaryotes include humans, animals, and plants. Scholars learn about the parts of eukaryotic cells. They design models of a store and match the correct function of each part to the function of a part of the cell. They review their...

How do you prevent the spread of water-borne illness in large public swimming areas? Scholars discover the challenges to identifying safe water through an inquiry experiment. They then produce posters sharing their understanding of water...

Looking for a tree-rific addition to your water cycle unit? Teams of young foresters examine the role of transpiration in the water cycle through a week's worth of activities. Pupils analyze how trees take in and transport water during...

Here's a great geology lesson for 3rd graders on weathering and erosion of soil. After a class discussion on how nature can "move a mountain," learners take a look at how a modern phenoma called acid rain can also cause weathering and...

Elementary schoolers take part in a very good lesson which has them watch video, conduct experiments, complete hands-on activities, and work in cooperative groups. The educationally-rich activities are clearly-explained, and the group...

Floating fragments of elodea can grow even without roots. Young scientists use eldoea plants to observe the oxygen production from photosynthesis. They study the difference between having access to high amounts of light and low amounts...

In China, hibiscus is known as the shoe flower because it is used to polish shoes, while in Hawaii, it is honored as the state flower. Young scientists learn about the structure and function of flowers. They dissect hibiscus...

Meteorologists view an animated video by the Environmental Protection Agency to learn how the carbon cycle works, and then move into groups to analyze and graph actual data of the atmospheric carbon dioxide concentration from Hawaii's...
