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...

Much like a distant planet, the underwater world of deep-sea benthos is strange and largely unknown. How do creatures survive and thrive in such extreme pressure and temperature conditions? Young oceanographers join the crew of Operation...

Why is lactase important? Biology scholars explore enzyme function in a structured inquiry lab. The activity tasks lab groups with observing how temperature and pH affect enzyme activity, as well as determining which milk products...

Does molecular mass affect the rate of diffusion? The simulation allows scholars to experiment with diffusion while varying the molecular mass and temperature. The timer automatically stops when a certain point is reached, making it easy...

How does hydrogen bonding explain ice crystals? An engaging interactive answers just that. Scholars explore how polar molecules interact and observe the changes as temperature fluctuates as well as the hydrogen bond attraction.

How does a hot air balloon fly? An experimental lesson has scholars build a balloon from a garbage bag and monitor the movement of air. As the temperature of the air in the balloon increases, gravity moves the denser cool air down,...

What did Earth look like 4.5 billion years ago, and what was the climate like then? Scholars explore a view of Earth throughout history. They observe continents moving, temperatures fluctuating, and huge changes in ecosystems. A...

There is a strong correlation between the carbon dioxide concentration in the air temperature. Scholars offer explanations for the correlation in one of four AP® free-response assessment questions. Their analyses in the other questions...

Who pilfered the pin? Scholars practice measurement skills as they solve the mystery of a stolen pin. They measure length, temperature, and mass and determine which of select suspects committed the crime. During the STEM hands-on...

Learners use the point-slope formula to determine the relationship between the Celsius and Fahrenheit scales of temperature. They use a graphing calculator to determine the slope of the line between two points in each scale.

A graph of Earth's average monthly temperatures from 1990 to 1994 is posted across the top of the page for meteorology masters to analyze. Five multiple choice questions are asked regarding temperature variation. This does not have to be...

In this gas laws learning exercise, students review how the gas laws effect pressure, temperature, and volume of gases. This learning exercise has 9 problems to solve.

In this gas laws worksheet, students calculate the volume, pressure or temperature of gases undergoing certain changes. This worksheet has 6 problems to solve.

Students experiment with sunlight and temperature. They study the definition of albedo, or the percentage of incoming sunlight that is reflected, rather than absorbed.

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...

In this temperature worksheet, learners color the thermometer to show the temperature. Students find the temperature for 7 thermometers.

Students investigate cooling rates of shallow and deep water, analyze Chesapeake Bay temperature information, and interpret effects of temperature variations on living organisms.

In this calculator activity worksheet, students learn to measure and find the temperature using a calculator. Students use the calculator to find the new temperature.

In this temperature worksheet, students read the given degrees and then color the thermometers to show the temperature for the 7 problems.

Young scholars determine the effect of temperature on the motion of particles.

Use an exciting role play activity to teach young chemists about the importance of heat transfer in maintaining homeostasis. They assume the role of a dog sled owner who has been abandoned and must fend for themselves with only a...

In this science experiment activity, students gather materials and perform an investigation using thermometers and prisms. Students are asked if red is hotter than blue. They answer 6 questions.

The presentation covers Fahrenheit, Celsius, and Kelvin scales for temperature as well as conduction, convection, and radiation.

Young mathematicians are shown a ruler, yardstick, tape measure and scale. They practice measuring length, width, height, and weight. They are then shown a thermometer, and discuss what a thermometer is used for. Everyone is shown how to...
