Don't give your classes the third degree. Use radians instead! While working with degrees, learners find that they are not efficient and explore radians as an alternative. They convert between the two measures and use radians with the...

Being a statistician means never having to say you're certain! Learners develop two-way frequency tables and calculate conditional and independent probabilities. They understand probability as a method of making a prediction. 

Time to experiment with mathematics! Learners study experimental design and how randomization applies. They emphasize the difference between random selection and random assignment and how both are important to the validation of the...

Help your classes find the significance in this lesson! Learners analyze the probability of Diff values. They then determine if the difference is significant based on their probability of occurrence. 

Extra! Extra! Read all about past and present energy use in a classroom-made historical newspaper. Useful as a cross-curricular assignment between science, history, and language arts, the project is sure to get young journalists...

Why do I have to do bean counting if I'm not going to become an accountant? The 24th installment of a 35-part module has the class conducting experiments using beans to collect data. Learners use exponential functions to model this...

Don't stop with two-dimensional learning, go to the next dimension! Learners verify that 3x3 matrices represent linear transformations in the third dimension. Additionally, they verify the algebraic properties that extend to vector...

One of the key questions in statistics is whether the results are good enough. Use an activity to help pupils understand the importance of sample size and the effect it has on variability. Groups collect their own sample data and compare...

Use statistics to decide if NFL quarterbacks earn their salaries! Learners study correlation coefficients after using technology to calculate regression equations. Through the data, they learn the meaning of correlation and correlation...

What did gender have to do with the survival rates of the Donner Party? Using comparative box plots, classes compare the ages of the survivors and nonsurvivors. Using the same method, individuals make conclusions about the...

Looking for a different approach to triangle congruence criteria? Employ transformations to determine congruent triangles. Learners list the transformations required to map one triangle to the next. They learn to identify congruence...

Build confidence by using multiple approaches to problem solving! This resource uses a visual and algebraic approach to solving application problems. A discussion is included about efficient approaches to different problems.

Math is all fun and games! Use a game strategy to introduce the concept of sequences and their recursive formulas. The activity emphasizes notation and vocabulary.

Look at climate change around the world using graphical representations and a hands-on learning simulation specified to particular cities around the world. Using an interactive website, young scientists follow the provided...

As part of a case study of U.S. immigration during the first part of the 20th century, class members examine a variety of primary sources that present multiple perspectives of the responses of those in favor of immigration and those...

Celebrate April's National Poetry Month or enrich a poetry unit with a wealth of language arts material. Class members develop an oral interpretation of a poem and/or develop a podcast interview with a poet. 

Article II, Section 1 of the U.S. Constitution takes center stage in a instructional activity that asks class members to assume the role of state senators, debate a resolution to amend the U. S. Constitution to permit naturalized...

What does slope have to do with lines? Pupils work with lines and determine the slope of the lines informally and with the slope formula. Groups use their knowledge to calculate the slopes of parallel and perpendicular lines. They also...

Use science to solve the mystery of the Poplar murder. Pupils use forensic botany to determine if a suspect could be the killer. By analyzing images from a Transmission Electron Microscope, learners determine if the material found on the...

Are the earth's oceans really just giant batteries, waiting for their energy to be harnessed? Middle school mechanical engineers will be shocked by the amazing amount of energy that forms around them after diving into part four of a...

As part of their study of the restoration projects on Santa Cruz Island, class members demonstrate their understanding of the connections among plant life, animals, and the actions of humans by crafting a model that reveals these...

What's life like aboard an ocean exploration vessel? Junior oceanographers examine the important role of communication in ocean research in lesson two of a five-part series from NOAA. The materials introduce the class to life on...

Sometimes scientists learn more from unexpected findings than from routine analysis! Junior oceanographers dive deep to explore hydrothermal vent communities in the fourth lesson in a series of five. Scholars examine data and look for...

Determine physical properties of potential packaging materials. Continuing from previous lessons in the series, the resource asks groups to identify physical properties of the substances. They test for conductivity, solubility, water...
