Are dinosaurs more like birds or reptiles? Learners put the question to the test by analyzing body temperature data from a 2014 study. With their analysis, they develop a theory about the body temperature regulation of dinosaurs.

What's the best way to record temperature over a long period of time? Scholars learn about collection of weather and temperature data by building thermistors in the fourth installment of the 10-part Discover Your Changing World series....

Water temperatures connect to the movement of the ocean. Pupils read two articles about the temperature and the motion of the oceans before small groups investigate the interaction of hot and cold water. Team members add cold and hot...

Verify the rule of thumb for finding the time of death. The project-based learning task asks pupils to determine when the rule of thumb process of finding the time of death is appropriate. Learners develop a function for the rule and...

New research proves even rinsing your mouth with carbohydrates without swallowing improves performance of the central nervous system. While some think sports drinks are amazing, others say they are a waste of money. Scholars learn about...

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...

How do temperature changes affect ocean currents? Scholars explore convection currents by demonstrating the flow of water in a baking dish. They use ice, heat, and food coloring to see currents. Then, they draw conclusions about their...

Do all liquids evaporate at the same rate? Young scientists observe the evaporation rate of three different liquids. They measure the time, the temperature, and the change in energy. After comparing the chemical formulas, scholars...

What's the difference between hibernation and a good nap? Find out with an engaging life science activity that compares the hibernation habits of grizzly bears and marmots. After learners read an informational passage about each mammal,...

Emerging biochemists more fully understand the flow of energy in ecosystems as they explore the laws of thermodynamics and relate them to energy transfer in food chains. They also investigate heat loss from the human body and how...

Scientists can't observe bonds breaking or forming, so how do they distinguish between exothermic and endothermic reactions? Young scholars complete two experiments to do just that. They monitor temperature change and calculate the...

Pique interest in water pressure, demonstrate buoyancy, and explore water displacement concepts with a homemade Cartesian diver. You may want to change the name of the toy, however, as is is not documented the Rene Descartes...

What can a Ganesh statue, hand ornament, and print block tell you about India? Introduce your learners to the geography, history, and culture of India by analyzing primary sources and using the well-designed worksheets provided in this...

What makes an effective warm-up and cool-down activity? as well as tips for leading stretches. Find detailed activity plans, as well as tips for leading stretches, for elementary school, tag-based games (including one game called "Toilet...

Learners must investigate the validity of a claim made in a running magazine. They must identify and look up unprovided information, make appropriate estimations, and be able to convert units. Might be best used as a group or whole-class...

A boss who can't do math? Oh, no! Young entrepreneurs use linear and exponential models to determine which discount will yield the most profit on ticket sales.

How long will it take to save up for a car? Classmates use linear and exponential models to see how money received during a Quinceanera will grow over time.

If you have ever had to adjust to a new time zone, you have noticed that it takes a while before you start to feel normal again. By shifting your sleep and activity schedule, you have altered the pattern of your body's circadian rhythms....

Explore the physiological effects of stress, and investigate the techniques of Tibetan monks to regulate their body temperature. Attach a thermistor to your fingertip to see if relaxation techniques can produce changes in body temperature.

Students practice estimating Fahrenheit temperatures using a thermometer in this interactive web lesson. Boiling, freezing, and human body temperatures are used as benchmarks for estimating.

This tutorial by Bill Nye explains why cold-blooded creatures need a warm environment to survive.

In this activity, learners explore the behavior of cold-blooded animals by observing what happens when they change a fly's temperature.

Students practice estimating Celsius temperatures using a thermometer in this interactive web lesson. Boiling, freezing, and human body temperatures are used as benchmarks for estimating.

Students make two models to stimulate the cooling rate of different skin surface areas. They use a Temperature Sensor to measure the cooling rate of the models. The students also compare the cooling rates of the models to determine the...
