Desert Dynamics
Students investigate the plants and animals found in Utah deserts and how these organisms have adapted to their environment. They brainstorm ways that desert plants are different from or similar to wetland plants.
Curated OER
Sugar and Light
Students connect starch to sugar as the storage form of energy. They find that no starch is produced in the plant without light. Students perform the old favorite of looking at starch deposition in geranium leaves using Lugol's iodine...
Curated OER
The Web of Life
Students participate in a game in which they discover the balance of life in the ocean. They identify different organisms that rely on different types of food. They answer questions to complete the lesson.
Curated OER
Dissolved Oxygen Lesson
Students investigate what dissolved oxygen is and why it is important to aquatic life and what factors influence levels of dissolved oxygen in a lake. They study how to use MS Excel to make charts to show trends and correlations.
Curated OER
Water Quality and Temperature
Young scholars are led through three activities to explore the effect of temperature fluctuations on the growth and survival of aquatic plants, clams, and shrimp eggs.
Curated OER
Primary Producers
Students examine the role of carbon in the oceans and how phytoplankton determine the levels present. In groups, they practice measuring primary productivity using two methods. They use the internet to research the role of phytoplankton...
Curated OER
The Biological Carbon Cycle
Students learn about the biological carbon cycle. In this carbon cycle lesson, students access the web site and mouse over the diagrams to follow the carbon cycle. They read about what happens to humans and plants during this cycle.
Curated OER
Pollution Solution
Fourth graders examine how trees help to absorb the pollution that is emitted from automobiles. They review the process of photosynthesis and determine how forest management is important on their reservation. They think about the...
Curated OER
Carbon and Oxygen Cycles
Students construct their own diagrams outlining the pathway of carbon and oxygen in the atmosphere. Students explain their diagrams outlining the pathway and teacher checks for accuracy and completion.
Curated OER
Don't Marry the Mole!
Third graders examine the power of solar energy. In groups, they create their own pizza box solar oven to discover the power of the sun and how it is a source for heat and light. To end the lesson, they use the internet to examine...
Curated OER
Observing the Growth Spurt
Pupils notice a growth spurt in their Brassica plants and closely monitor this growth by measuring their plants and predicting the next day's growth based on the pattern of their data. They also read and highlight the objectives in each...
Curated OER
Mini-Ecosystems
Students use plastic bottles to create terrariums and plant Venus Flytraps. They observe the plants and the terrariums for illustrations of the water cycle and species' adaptations to a specific environment.
Curated OER
Food webs and Energy Flows
Students become familiar with food chains. In this food chains lesson, students understand that as consumers eat other consumers energy is passed. Students understand the vocabulary associated with food chains.
Curated OER
Thinning and Transplanting
Students identify and observe one plant per section in their quad and to transplant the surplus seedlings to empty quads and interpret why this is important. They then discuss the purpose of thinning and transplanting. Finally, students...
