The "Bottled Bacteria" activity instructions are a bit unclear, but the remaining activities investigating limiting factors in ecosystems are well-written. Learners model the exosystem of a bear and a herd of deer. They set up a...

How does a population's habitat determine the size of that population? Teach learners about carrying capacity and limiting factors with an engaging roleplay activity. Class members pose as a colony of penguins who must gather food amidst...

Life has its ups and downs ... especially if you're an animal! Biology scholars engage in a population study through an inquiry-based lesson plan. Pupils work together to explore the factors that affect deer populations, then examine the...

Observing plant succession doesn't have to be a decade long process. A hands-on lesson has groups study succession over a designated space. Learners use their observation skills to record differences in plant and soil characteristics in...

Students identify the three realms of the Arctic Ocean, and describe the relationships between these realms. They identify major factors that limit primary productivity in the Arctic Ocean.

Learners demonstrate the scientific method by conducting an ice cube melting experiment. They make predictions and observations, and conclude what factors make ice melt more slowly or quickly than normal.

Students explore the biotic and abiotic factors that affect plant reproduction and the potential consequences of human activities on plant populations. The effects of urbanization are discussed as an influence in the consequences.

Young scholars discuss how soil permeability is affected by permafrost. In this soil lesson plan, students freeze soil over night, and discuss how the environmental conditions of freezing affect soil and further affect vegetation.

Sixth graders create a Bahamian terrarium. In this Bahamian ecosystem lesson, 6th graders watch a PowerPoint to see Bahamian biotic and abiotic factors. They bring in 2-3 items for their terrarium. 

Rational expressions are just fancy fractions! Pupils apply fractions concepts to rational expressions. They find equivalent expressions by simplifying rational expressions using factoring. They include limits to the domain of the...

Young scholars use scientific methods to investigate the effects of overpopulation of seed plants on growth in a limited living space. Students relate seed plant population findings to that of other organisms.

Students watch a video on population dynamics. They conduct an experiment where they fill up a designated space with students. They recreate multiplying rabbits using beans.

Students investigate the effects of soil temperature, water availability, photo period and other variables of the growth of purple loosestrife. They observe the growing conditions of plants and alter them by adding water, isolating the...

High schoolers will identify the factors that contribute to erosion and weathering. They will start by differentiating between chemical and mechanical weathering. They then apply what they learned by playing the online jeopardy game. Key...

Students participate in an adaptation scavenger hunt at. They obtain various plant specimens, and sort the plants based on whether they came from a desert, tropical rainforest, or wetlands.

How many cars would be involved in a traffic jam 12 miles long? A slightly ambiguous writing prompt gives learners the opportunity to practice making reasonable assumptions to tackle a real-life problem. Few details are given, so they...

Young mathematicians explore the maximun area for patio with the added complexity of finding the mimimum cost for construction. First, they maximize the area of a yard given a limited amount of fence and  plot width v. area on a...

Students are taught how to use the climatology section of the Digital Atlas of Idaho. They discuss the major factors influencing climate. Students gather and synthesize new information to enrich their comprehension of climate factors.

Students design and conduct an experiment to determine the effect of salinity and temperature changes in the movement of ocean currents. In this earth science lesson plan, students record observations and collect data. They share their...

The title says it all: Could King Kong exist? Investigate how increasing the dimensions of an object affects its surface area and volume to mathematically conclude whether a creature with the weight and height of King Kong could actually...

How far does the human hand reach?  Five interactive lessons lead classes through a unit exploring the human impact on ocean resources, pollution, and even extinction. Learners discover how their decisions affect the ocean...

Tenth graders are introduced to the process of succession and gain awareness of the changing nature of ecosystems. They demonstrate a comprehension of the dynamic nature of ecosystems, including the relationship between ecological...

Young scholars discuss water rights. In this science lesson, students simulate an exercise whereby they begin to understand the meaning of water allocation and limited water supplies by actually passing out water from a jug.

Students explain how uneven heating of Earth affects wind and water currents. They describe the limits on current technology in predicting weather and how the Water Cycle is related to local weather.
