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...

How do the laws of motion work in space? Learners explore Newton's laws of motion in different experiments as part of the Christa's Lost Lessons series. They rotate around the room in three stations to experience each law in action using...

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

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...

Catch the fast wave. Using a computer simulation, pupils experiment with amplitude, frequency, damping, and tension of a string to determine which affects the speed of the wave. Learners record the observations to determine their...

Tag, you're eaten! A lesson on predator-prey relationships uses the game freeze tag as a model. Learners become either a predator or prey and play a game of tag as the prey tries to reach areas that house food and shelter. During the...

Given a scenario in which a class member wants to prove his height is not an outlier, pairs devise a plan and gather evidence to help support his claim. The small groups implement their plans and create graphical displays of their data...

Can I afford to go to college? Small groups design a method to research college tuition for several years and make a prediction of costs in 2025. Classmates plot the the data on a scatter plot and graph the line of best fit to make their...

Fine the normality of fall measurements. Pairs collect measurements of fall leaves and one other fall object. Using the measurements, the groups determine the descriptive statistics for the object and using the Empirical Rule, figure out...

Recording scientific evidence allows for important discoveries and conclusions. A remote learning resource outlines how to create a field journal to record scientific observations. The outline resource includes notation about the...

Teachers demonstrate water runoff on a hill and its effect on soil erosion. Pupils observe as the instructor changes the steepness of the hill and see whether vegetation covers the soil. Learners then use their observations to make...

After reviewing notes from the previous lessons, small groups obtain a scenario card that describes a situation in which bullying is happening. Peers discuss the event and brainstorm two solutions using the STAR method then present their...

Are there differences in the brains of liberals and conservatives? That is the question young political scientists are challenged to answer. Class members examine studies, consider how the results are presented, and how the studies were...

In an age of inflamed politics, who votes, who doesn't vote, and why are the questions everyone is trying to answer. Pupils listen to scholars, journalists and data crunchers on voting statistics to make their own conclusions. A chart...

Don't jump to conclusions but to products instead. Pupils participate in an online race as penguins. Users choose the ice sheet with the correct product to the individual's multiplication prompt. The penguins jump from one product to...

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...

Time for a virtual sightseeing trip. Pupils explore the Grand Canyon, Devil's Tower, and Yosemite Valley in an interactive online experience. They answer questions about the organisms in each location and draw conclusions based on their...

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 virus-fighting time! Pupils learn how viruses attack and reproduce and how the immune system works to protect the body. They identify unfamiliar terms and tissues and organs of the immune system. Working in small groups, scholars...

At some point the rate of change must be the average. Pupils first see the definition of the Mean Value Theorem and hear an explanation of it in simple terms. The helpful video then compares the Mean Value Theorem with the Intermediate...
