Learners apply critical thinking skills as they analyze data about the temperature inside a gymnasium during a school assembly. The focus is on representing temperature as a function of time and interpreting input and output values...

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...

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...

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...

Turn your algebra learners into meteorologists. Students are given three graphs that contain information about the weather in Santa Rosa, California during the month of February, 2012. Graph one shows temperatures, graph two displays the...

Does it feel a little humid in here? Learners assume the role of water vapor in the atmosphere as they explore the differences between warm and cold air. They roll dice to determine their level of energy, which determines if they...

Future weather forecasters collect daily temperatures over a period of time. Afterward, they compare their data with monthly averages, as researched on national weather websites, in order to grasp the difference between weather and...

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...

Are you feeling the pressure? Let loose a little with a kinesthetic activity that models molecular motion in a closed space! The activity varies conditions such as volume and temperature and examines the effects on molecules.

What adaptations exist in order for icefish to survive the subfreezing temperatures of the Antarctic Ocean? Middle and high schoolers can find out through watching a related 13-minute video and performing a simple investigation to...

Shine some light on the topic of seasonal change with this collection of activities. Whether it's by measuring the change in the length of their shadows, or modeling the earth's orbit around the sun using a lamp and a globe, these...

With Earth Day quickly approaching, as well as many science fairs, why not challenge your class to investigate geothermal energy or other renewable energy resources? There are five driving questions explored in depth here, as well as...

There has been a huge solar energy spill! Let's go outside to play in it. This lesson includes multiple experiments showcasing solar and wind energies. Scholars build a solar heater and an anemometer before testing the results. The...

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...

According to the United Nations, climate change affects every country on the planet. This research project encourages scholars to explore the factors that affect climate change from different perspectives: climate scientist, policy...

The United States is the world's largest producer of biofuel. During an in-class investigation, young scientists produce their own biodiesel. They burn a sample of it to determine the heat of combustion. Then they discuss the...

Outer space may be a lot closer than you think! Science scholars model the layers of the atmosphere using transparencies to gain insight into the scale of space. The resource includes ideas to tailor the activity to the skill level of...

Why not review for that chemistry test with a little healthy classroom competition? With a fun and interactive Jeopardy-style game, you can adjust the number of teams, keep track of scores, and even make your own test if the provided...

Learners investigate how solar energy is converted into heat in part two of the 10-part Discover Your Changing World series. They build and test homemade solar cookers to boil water and cook rice. Pupils consider the impact of heat...

There's a little bit about every aspect of weather in this trivia game. The lesson resource provides 36 questions and answers pertaining to four different topics related to weather: effects, science, technology, and statistics. Groups...

Model the earth's core with a neat activity that uses science as an inquiry and step-by-step procedures. The activity acquires a lot of assistance from the teacher or volunteer helpers. 

Not only do future engineers learn the difference between accuracy and precision, they also get some hands-on experience using different measuring tools.
