Teach your class how to use descriptive statistics through a hands-on data collection activity. Pupils collect their own data, calculate test statistics, and interpret the results in context. They compare male and female results, looking...

How does chemistry help deep-sea explorers? Part four of a five-part series of lessons from aboard the Okeanos Explorer introduces middle school scientists to technologies used in ocean exploration. Groups work together to analyze data...

Nanofibers can be made through electrospinning or force spinning in order to reduce the negative impact on the environment. Pupils study the role of fibers and dye on the environment through a series of five hands-on activities. Then,...

Equip your chemistry class with the tools to properly understand endothermic and exothermic reactions. Young chemists collect, analyze, and graph data to determine how the Law of Conservation of Matter is applied to chemical...

Become a bean counter. Pupils use a fun activity to design and execute an experiment to determine whether they can grab more beans with their dominant hand or non-dominant hand. They use the class data to create scatter plots and then...

Take charge of your biology class by using this exciting analogy to relate the ATP process with batteries. Pupils use batteries and rubber bands to simulate the phosphate bonds between molecules in the body. They measure the distance in...

Caffeine affects your heart rate — or does it? Learners study experimental design while conducting their own experiment. They collect heart rate data after drinking a caffeinated beverage, create a box plot, and draw conclusions....

How can you tell the difference between endothermic and exothermic reactions? Chemistry scholars perform and observe two chemical reactions, measure the temperature throughout, then draw conclusions about changes in energy from their...

Dust is everywhere around us; it's unavoidable. But what exactly is dust and are certain locations dustier than others? These are the questions students try to answer in an interesting scientific investigation. Working independently or...

Let's go fly a kite. By flying a kite, class members observe the difference in air flow. The class notices the characteristics of banners tied to the kite string to determine where wind turbulence stops. Adding an anemometer to...

How much does your class know about the relationship between climate change and carbon dioxide? Science scholars explore the nature of greenhouse gases and rising ocean temperature through demonstrations, research, and experiments. The...

Looking for an easy way to give your class experience with acid-base chemistry outside the lab? Try a detailed interactive that puts them in total control! Young chemists determine the dissociation constant and concentration of an...

Turn up the heat! Young mathematicians develop models to represent different climates and collect temperature data. They analyze the data with regression and residual applications. Using that information, they make conclusions about...

It's time to increase the heat! Young chemists demonstrate heat transfer and heat capacity in an activity-packed lab, showing the transitions between solid, liquid, and gaseous phases of materials. Individuals plot data as the...

It's an extravaganza of excrement! Do your pupils understand that waste doesn't really go to waste? Introduce the nitrogen cycle with an interesting instructional activity and lab from the K20 series. The activities include a look at...

Take your class up, up, and away with an engaging weather balloon simulation! Individuals get hands-on experience in creating and launching their own airborne labs to study how temperature and pressure affect substances at 100,000...

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....

Assist your class with correctly calculating the values for force, work, and power as they determine the amount various activities require. They gather data and participate in a group discussion to compare results upon conclusion of the...

Finally, a project pupils will instantly like! Young mathematicians collect data on the number of likes they receive for a social media post over time. During the first part of the project, they determine a curve of best fit and...

Here's the perfect lesson for those who think the world needs faster pumps. Building on the previous activity, scholars work to make the pumps function faster in transferring water between containers. They try adding an additional solar...

Is time on your side? Pupils come up with an experiment to test whether their classmates can guess how long it takes for 30 seconds to elapse. They divide the class data into two groups, create box-and-whisker plots, and analyze the...

Herbivores and carnivores just don't get along. Using a box of animal crackers, classes collect data about the injury status of herbivores and carnivores in the box. They complete the process of chi-square testing on the data from...

Certain things just do not mix, including liquids of varying densities. Learners collect data to determine the densities of several liquids. They then use the density information to predict the type of liquid.

Plant respiration can be a difficult concept for young biologists to grasp; with a hands-on lab, learners can collect and graph data, then calculate the metabolism rate for the plants they studied. If you do not have a respirometer,...
