Extinction events have happen throughout geologic history, but only five mass extinctions occurred over the last 4.5 billion years. Scholars view fossils from a layer of sediment during an extinction event and observe patterns to draw...

Slow the spread of disease by slowing disease carriers in their tracks. Learners explore just how they might accomplish this as they experiment with the life cycle of a mosquito under different conditions. Scholars design and conduct...

Different types of mutations cause unique types and degrees of muscular dystrophy. Scholars learn about the types of mutations and the impact on the body. They compare the location of the mutations and draw conclusions about how it is...

The novels of John Green cover the gamut of teenager emotions. A guide to his works provides classroom lesson plans for the novels Looking for Alaska, An Abundance of Katherines, The Fault in Our Stars, and Paper Towns. Each lesson...

An environmental factor, such as a drought, sometimes speeds up the rate of natural selection. Scholars analyze data on the beaks of birds around the time of the drought. They compare those that survived to those that perished and find...

Have you ever wondered why some people are lactose intolerant? Participants test simulated patients in a hands-on lab activity to find out! They learn about lactose intolerance by performing an experiment, analyzing data, and drawing...

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...

How are chemical reactions affected by gravity? Learners explore the phenomenon of effervescence as part of the Christa's Lost Lessons series. They compare findings in an experiment on effervescence to a video of a similar experiment in...

Do you want to be a detective by analyzing situations? An engaging lesson plan provides young historians with the tools to help them understand the difference between data types and how to analyze them to draw conclusions. Scholars...

Why do rocks break down over time? Learners explore this concept by simulating physical and chemical weathering of different types of rocks. They use an abrasive to demonstrate physical weathering and acid to demonstrate chemical...

What exactly are those glowing eyes in the night? Learners run an experiment to attract local wildlife and then document the number of visitors by identifying their tracks. They then analyze the data to draw conclusions about the types...

Scientists use data to learn about species survival—and your classes can too! A set of four lessons guides learners through a process to draw conclusions about the fluctuations in the population of the Hellbender species. They read...

Data can tell us a lot about celestial objects that are just too far away to study otherwise. Learners examine data on the brightness of an asteroid to predict its rotation rate. Graphing the data reveals a periodic pattern that allows...

Is the sky falling? Learners use a simulator to modify the mass and velocity of asteroids and collect data on how they influence the diameter and depth of the impact crater. They use their results to draw conclusions and make predictions...

Can plants grow on the moon? The second lesson in a five-part series has pupils explore the resources available on the moon to determine if plant life is possible. They use lava rocks as their soil and draw conclusions about the...

Stars may all look the same from down here, but their surfaces tell a different story. Using an animation, learners collect data about the temperature and luminosity of stars and compare them to their mass and radius. They then answer...

It's all about the material. Learners experiment with different substances as they try to keep an ice cube from melting. They draw conclusions by answering a set of questions about the types and amount of material that had the best result.
