More than half the world's population eats rice as a daily staple ... imagine if that rice could prevent illness. Scientists genetically engineered rice to include vitamin A for just that purpose. However, room for debate still exists....

There is bias in many aspects of our lives, and math is no exception! Learners explore provided data to understand the meaning of biased and random samples. The resource includes various data sets from the same population, and...

On your mark, get set, GO! The class sprints toward the conclusions in a race analysis activity. The staggered start of the 400-m foot race is taken apart in detail, and then learners step back and develop some overall race strategy...

How significant was the Cold War during the 20th century? After reading and analyzing speeches by Ronald Reagan and Mikhail Gorbachev, learners consider the historical context of foreign policy decisions made during the Cold...

Sometimes the indirect path is best. Scholars determine whether the sum of a rational number and an irrational number is irrational. Reading a transcript of a conversation between classmates leads to an indirect proof of this concept.

One of the basic properties of inscribed angles gets a triangle proof treatment in a short but detailed exercise. Leading directions take the learner through identifying characteristics of a circle and how they relate to angles and...

How do astronauts do anything with those gloves on? Learners mimic what astronauts need to overcome as they complete puzzles while wearing multiple gloves. They time themselves and use the information to draw conclusions about the...

Genetics learners read an article and watch a video about personalized medicine and the hope it holds for treating patients more specifically than doctors currently are able to. They research, design, and produce a brochure about the...

Explore the effect of outliers through an analysis of mean, median, and standard deviation. Your classes examine and compare these measures for two groups. They must make sense of a group that has a higher mean but lower median compared...

Collaboration is the key for this equation-solving lesson. Learners solve a multi-step linear equation that requires using the distributive property. Within collaborative groups, scholars discuss multiple methods and troubleshoot mistakes.

Class members are transformed into explorers as they work in groups to locate hidden items and map their journey along the way. They then leave clues for other groups of students to follow, and ultimately discover how past explorations...

Buying a new sofa? Learn how to use the Pythagorean Theorem, as well as algebra and graphing techniques, to determine whether the sofa will fit around a corner (which I'm sure you'll agree is a very important consideration!).

Dr. Martin Luther King, Jr.'s "Letter from Birmingham Jail" serves as an exemplar for a mini-lesson on semicolons. Working alone or in small groups, class members first circle all the semicolons in the letter, and then consider how this...

Introduce your algebra learners to linear and quadratic functions. Learners compare the differences and relate them back to the equations and graphs. Lead your class to discussions on the properties of a function or a constant slope...

Young geometers flex their transformation muscles in this brief but powerful exercise using dilations and translations to develop the similarity of circles. The plan provides guidelines to help learners navigate a pair of...

What's that lurking in the shadows? An activity that demonstrates how eclipses happen. Science scholars investigate how light and distance interact to form shadows. The experiment uses simple materials to generate data and observations...

Trying to get your class to think of decimals as fractions and vice versa can lead to interesting discussions. After all, we can usually understand quickly that 1/4 is .25 but why is 1/7 not so easy to convert? This activity looks...

Although our connections to those who personally witnessed the Holocaust are dwindling, this lesson focuses on conducting an interview and getting some primary source material. There is a list of resources your high schoolers can...

Diversity in a biome leads to some unique characteristics vital to the natural environment. Young scholars use an interactive map to explore the vegetation and climate of the Gorongosa National Park. They collect climate data to compare...

All the Common Core standards are important, but they all build off the ability to cite textual evidence to support analysis. See how to scaffold this standard into three steps of development, along with assessment ideas with the ideas...

Whodunnit? Find out who killed Mr. Brooks through a logical examination of evidence. Class members fill out a couple of data tables to help them pin down the suspect. After they've figured out just who the culprit is, pupils compose...
