Apply scientific principles to designing an experiment to study organisms living on the coral reef in our oceans. Through reading, individuals learn about the coral reef ecosystem and important factors that affect its function....

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...

They say you can interpret statistics to say what you want them to. Teach your classes to recognize valid experimental results! Pupils analyze experiments and identify flaws in design or statistics. 

What are the chances? Teach your classes to answer this question using mathematics. The first part of a three-day lesson on determining significance differences in experimental data prompts learners to analyze the data by...

Learners make predictions and draw conclusions from given information as they learn the meaning of probability in this vocabulary-rich, integrated activity that presents a variety of teaching strategies to motivate and reach...

It takes a lot of planning to achieve a random result! Learners compare results of random assignment, and conclude that random assignment allows results to be attributed to chance. They also realize the set of random means...

How likely is it that the school cafeteria will serve chicken tomorrow? Discover the concept of probability with the roll of the dice. Pupils evaluate the liklihood of several statments about everyday life. Then, a mathematical...

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. 

Pupils analyze group data to identify significant differences. They use simulation to create their own random assignment data for comparison. 

Look around and explore. Little ones use their five senses with some day-to-day activities designed to guide observation and apply STEM strategies. Young scientists learn through comparing/contrasting and...

Create the ultimate miniature golf course. The 93-page model curriculum unit from the Massachusetts Department of Elementary and Secondary Education contains nine lessons on understanding similarity in terms of both Euclidean geometry...

Not all liquids are the same. Investigate the viscosity of different fluids with a series of activities designed for eighth grade science. As learners move through learning centers with different experiment setups, they determine...

You are what you eat, as they say! Are you more starch or more protein? Young scholars use their knowledge of each component to test different foods for their content. Using multiple indicators, individuals describe the protein and...

Create a small but useful little program that allows you move a dot with your mouse and see the coordinates change as the mouse moves.  Starting with a dot that moves with the mouse, add to this program the text of the points...

William Shakespeare penned some of the richest and most fascinating works of literature—or did he? Middle schoolers read three brief informative passages and conduct additional research to evaluate the claim that Shakespeare did not...

The world is a stage, and so is your classroom! Hone the skills of the next generation of Tony® award winners with a set of exercises, reference pages, writing prompts, and excerpts from famous plays.

Very simply, geometers examine a pair of rectangles on graph paper and find a translation and rotation to demonstrate their congruence. A couple of questions follow to stimulate critical thinking about other possibilities.

Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...
