So many bodily activities depend on homeostasis! Give learners a solid background to understand the basic process of the human body. Scholars first examine negative feedback loops contributing to body temperature regulation and then a...

More asthma attacks happen at higher altitudes, but why? Scholars complete worksheets, learning about homeostasis and feedback related to breathing. Then, they work in small groups to experiment with breathing in limited amounts of...

How much negative feedback does a body get daily? The interactive walks through one negative feedback loop, increasing body temperature. Then it challenges scholars to relate this to mechanical feedback loops and disorders that prevent...

Many glands work together to control hormone levels in the body. The interactive focuses on the thyroid gland, pituitary gland, and the hypothalamus. It demonstrates the interconnections and feedback loops present in the endocrine system.

The greenhouse effect warms up earth enough so it can support life, but if it heats up too much, life won't be able to survive. An interactive presentation covers the greenhouse effect, the carbon cycle, climate forcing, and climate...

For this homeostasis worksheet, students sketch and label graphs showing homeostasis for the following conditions: blood glucose, temperature, systolic blood pressure, and blood pH. Students define and give an example of positive...

In this homeostasis worksheet, students answer twelve questions about positive and negative feedback loops and how they effect homeostasis.

If the Lorax were to write a letter, what would he write? Introduce your class to systems and feedback loops through the whimsical stylings of Dr. Seuss. Learners take on the Lorax's point of view to write a letter, among other activities.

Whether you're battling the flu or trying to warm up on a chilly day, your body's ability to react to temperature change is fascinating! Anatomy scholars discover the fantastic feedback loops that control body temperature in a rigorous...

Examine the structures of the kidney and then define the functions of the specialised structures.  Every will find this powerpoint engaging, many of the images will present facts such as osmolarity of interstitial fluid and the...

The thaw depth of tundra creates a positive feedback loop with both global warming and the carbon cycle. Scholars sort photos and develop a hypothesis for ground cover and permafrost depth. Then they review the data and measurements...

Students explore the history of taxonomy, the work of Carl Linnaeus, and the factors involved in the decline and extinction of a variety of botanical species.

Young scholars plan and construct a "mini-lab" to measure the reflectivity of different earth surfaces. They measure reflectivity of materials, including ice, soil, rocks, etc., and then extrapolate from what they have learned to...

In this photosynthesis, disease and Immune System worksheet, learners fill in the blanks with key terms to complete sentences about the transfer of energy from the sun to plants, enzymes as catalysts in reactions, homeostasis, the immune...

In this circuit worksheet students complete a series of short answer questions using circuit diagrams to show the input and output of different switches. 

Young scholars will work cooperatively. In this environmental lesson plan, students will start by discussing an article and its questions prior to receiving a handout. There are two versions of the handout depending if your young...

Introduce cradle-to-cradle design thinking. Scholars first discuss the importance of natural laws and rights. They then use a variety of online and print resources to research eco-efficiency and cradle-to-cradle design.

Students explore the carbon cycle. In this carbon cycle lesson, students discuss the four main reservoirs where carbon is stored and then discover the process through which each reservoir absorbs and releases CO2. This lesson includes a...

Students explain the process of wave formation and analyze the relationship between the ocean and the atmosphere.  In this oceans lesson students use buoys to cast real time sea state conditions. 

Ninth graders explain how a scanning tunneling microscope works. In this chemistry lesson, 9th graders construct atomic models and simulate how their images appear under the STM. They discuss the limitations of their atomic model.

Students compare a stepper motor from a traditional motor. In this physics lesson, students summarize how it works. They build their own stepper motor and explore its uses.

Students examine carbon dioxide and determine the impact of greenhouse gases on the earths spheres.  In this pollution lesson students complete a lab activity to see the impact of gases on the environment, 

This is the seventh of nine lessons from a student learning module called "Visualizing and Understanding the Science of Climate Change." This lesson addresses climate feedback loops and how these loops help drive and regulate Earth's...

This is the seventh lesson in a series of learning modules on the topic of climate change. In this lesson, you will learn how several important feedback loops help drive and regulate earth's unique climate system and affect climate...
