Curated OER
Ecosystems - Plants and Animals Together
Students study the biotic and abiotic factors of an environment. In this exploratory lesson plan students examine the different trophic levels and how organisms are connected.

Temperate Forest: Comparing Deciduous and Evergreen Trees
Students compare deciduous and evergreen trees. In this tree lesson, students list the differences between these two species of trees.
Curated OER
Plant Transpiration
Students conduct various experiments to investigate plant transpiration. In this biology lesson, students explain how this process helps maintain the hydrologic cycle. They measure the rate of water loss in plants using a potometer.
Curated OER
Color Change in Leaves
High schoolers identify the different leaf pigments and colors. In this biology activity, students perform chromatography to separate them. They explain how light affects green leaf colors and causes falling leaves in autumn.
Curated OER
Where Do Plants Get Their Food?
Students think about the historical development of the scientific method. They design an experiment that replicates van Helmont's, using only specified materials. Pupils then improved upon van Helmont's procedure and also consider the...

Why Plants Are Green
Young scholars discover the properties of chlorophyll in plants. In this plant biology lesson, students conduct an experiment to find where the chlorophyll in the plant is located. Young scholars are split into small groups and study...
Curated OER
Biogeochemical Cycles
Learners demonstrate comprehension of the energy sources of various cycles by completing mini stories. They demonstrate analysis of words by defining individual word parts and combining them to form definitions. Students demonstrate...

I See a Coyote
Students role-play coyotes looking for natural resources. For this natural resources lesson, students examine the relationship between animal life and the environment. Students play a game that demonstrates how natural...
Curated OER
Glucose
High schoolers conduct various experiments on glucose. In this biology lesson, students differentiate the process of diffusion and osmosis. They test different foods for the presence of glucose and starch.
Curated OER
A Piece of Cake: Ocean Communities
Students explain habitats. In this model based lesson students create a model to help describe a habitat that is typical of deep-water. Students will describe how organisms such as coral and sponges add to their habitat.
Curated OER
What's Down There
Students write an essay about the coral reefs. For this oceanography lesson, students investigate the reef of Bonaire and compare it to reefs that are not thriving. Students then explore the differences that contribute to the overall...
Curated OER
Plant Pigments
Students investigate the components of chlorophyll. They use paper chromatography to separate the many pigments of chlorophyll from one another.
Curated OER
Deep Gardens
Learners compare and contrast deep-sea coral reefs with shallow-water coral reefs. In this underwater ecology lesson, students describe three types of coral and explain why scientists are concerned about the future of deep-sea coral.
Curated OER
Trees and Their Parts
Students research trees and their parts. In this forestry lesson, students participate in various learning stations to identify trees by matching the photographs of the tree to the correct name.
Curated OER
All About Plants
Young scholars identify plant needs. In this biology lesson, students watch All About Plants and then write a paragraph describing the various details about plants.
Curated OER
Teaching about the Effect of pH on Aquatic Organisms
Students perform experiments to determine the PH, acidity, and buffering qualities of a lake that make them sensitive to acid deposition.
Curated OER
Algae Part One: An Introduction
Students have the opportunity to view two types of algae under 400x magnification with a compound microscope. They make observations and record their observations through drawings and words. In addition, they identify different qualities...

Phyto- v. Zoo- Plankton
Students identify two broad groups of plankton: phytoplankton and zoo plankton. They describe the general body adaptations which characterize each group. They discuss and write about what it would be like to be carried around by the...
Curated OER
What Influences Reaction Rate?
Learners study reaction rates, what determines how fast a reaction happens and how the chemical changes occur. In this reactions lesson students complete a lab where they use Alka-Seltzer to observe reaction rate and create a graph...
Curated OER
Carbon Adventures Game
Sixth graders examine the processes and transformations that occur in carbon pools. They play a game to identify paths taken by carbon through the environment.
Curated OER
Web of Life - Alaska
Seventh graders research Alaska, then construct their own food web after researching a habitat of their choice.

How Do Green Plants Grow?
Pupils explore how seeds grow. They design an experiment and predict its outcome.
Curated OER
Fall Slumbers
Students observe changes in a selected tree leaf near their homes during the fall. Twice each week students record changes in the leaf using words, pictures, and numbers.
