Learners collect data on the amount of water left in a bottle over time. They graph the data to determine whether the scatter plot shows a curved or straight relationship. Group members then determine an equation for the curve of best...

Play some games, develop a law, and then call it a day. Learners first perform a small number of trials for a probability experiment, then predict the result for a larger number of trials. They then compile data from the entire class to...

Given the price of crude oil, gasoline, and diesel for the past several years, pupils plot the data to determine whether a correlation exists. Learners determine a regression line and predict the price of gasoline and diesel in the...

How fast does it grow? Scholars work on two tasks dealing with exponential growth, one on population growth and the second on investments. Learners research a country's population over the past century and make predictions of the current...

Use graphs to interpret life in 136 counties. Pupils analyze histograms and describe the shapes of the distributions of data collected from several counties on different aspects of life. Scholars make predictions on the difference in...

Will the block float? Pupils take measurements to calculate the volume of various blocks of different materials. Using a scale, they determine the mass of each block and then calculate their densities. Scholars finish by ranking the...

The difference between sinking and floating may be a little salt. Young experimenters analyze the effect of salt and temperature on the density of water. They use their results to predict the effect of climate change on ocean ecosystems.

High schoolers begin a discussion on diversity and determine the percent of the population that speak another language at home in the US. Classmates make a prediction of the percentage of people that speak another language at home in...

Tornado winds can reach more than 200 miles per hour. Learners explore wind speeds and more characteristics of tornadoes with an online lesson. They learn how tornadoes form and how scientists attempt to predict them. Can be used as an...

Obviously, a sturdy bridge is the desired outcome. Pupils select from one of four different types of truss bridges, then construct a model of the bridge from craft sticks and glue, making sure that it satisfies certain constraints. They...

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...

From solid to liquid and then back again. Young scientists  dissolve salt in water and then evaporate the water while observing what happens to the solute. They use their observations to make predictions about other solutions.

Bring the excitement of genetics to scholars with a dynamic hands-on meiosis modeling experience. During the activity, biologists follow step-by-step procedures to build chromosomes, model independent assortment, learn about crossing...

Bring evaporation right into the hands of young scientists with an entertaining, hands-on activity. Investigators view videos and images while participating in class dialogue focused on water evaporating from surfaces. A short experiment...

Changes to habitats mean changes to resources. Groups examine aerial maps to predict areas of low and high plant resources. After formulating a plan, they visit the areas to collect data about the plant resources and then share their...

Scholars predict the sound of a tyrannosaurus rex roar with a mixing board equipped with audio from crocodiles, chickens, loon, macaw, peccary, sea lion, and bison.

Chew on an activity for probability. Given information on the number of gumballs in a gumball machine, scholars consider how likely it is to randomly draw a blue gumball and how many of each color they would draw in 10 trials if the...

Multiply the amount of probability using addition. Pupils use probabilities to make predictions in problems. They find shortcuts to find probabilities instead of listing the entire sample space. The learners then use the multiplication...

Discuss different sources of energy and how much greenhouse gas each might emit. The six sources are then ranked according to emissions from greatest to least. Finally, the true cumulative emissions are revealed to show the class how...

Sometimes, despite the best laid plans, the unexpected will occur. Learners witness this firsthand as they carefully design an experiment to determine the time needed for ice to melt in salt water or pure water. They uncover facts not...

Climate models mathematically represent the interactions of the atmosphere, oceans, land, sun, surface, and ice. Part two in the series of four lessons looks at the role greenhouse gases play in keeping Earth warm and has participants...

While many mutations are neutral, those that appear advantageous increase in frequency in a population. Scholars use illustrations to make predictions about populations of mice. They follow it up with a video to confirm or refute their...

Searching for a detailed lesson to assist in describing rotations while keeping the class attentive? Individuals manipulate rotations in this application-based lesson depending on each parameter. They construct models depending on the...

Programming a robot is a mathematical task! The activity asks learners to examine the process of programming a robot to vacuum a room. They use a coordinate plane to model the room, write equations to represent movement, determine the...
