A diameter is the longest chord possible, but that's not the only relationship between chords and diameters! Young geometry pupils construct perpendicular bisectors of chords to develop a conjecture about the relationships between chords...

Math modeling is made easy with the first installment of a 16-part module that teaches pupils to model real-world situations as linear relationships. They create graphs, tables of values, and equations given verbal descriptions.

Students research psychology by examining real life situations. In this human relationships instructional activity, students discuss the importance of respect among two people in a romantic relationship. Students examine images of people...

Students investigate mass-mass relationships using potassium carbonate and hydrochloric acid. In this mass-mass relationship lesson plan, students measure a certain amount of potassium carbonate and determine how much hydrochloric acid...

Some say a picture is worth a thousand words—even from a hundred miles away! Learners review satellite data to analyze ocean variables such as temperature, salinity, evaporation, and precipitation. They look for patterns in the data and...

Students investigate geometric relationship using conjecture about linear pairs and vertical angles. In this geometry lesson, students apply their theorems and previous geometry knowledge to solve for and find angles of linear...

Students describe environmental interrelationships using list of criteria. They are able to explain organism interaction, based on definitions provided. Also, students can use references and worksheets, to describe effects of pollution...

Consider the relationship between side length and area as an input-output function. Scholars create input-output tables for the area of squares to determine an equation in the first installment of a three-part unit. Ditto for the area of...

We are very dependent upon other life forms around us to survive. Here, scholars explore relationships in the ecosystem with the help of Auntie Litter and the pollution patrol. They imagine a world without grass, making connections to...

Learners investigate the area of various figures. They construct triangles and quadrilaterals using Cabri Jr. and discuss the relationships between different angles, side lengths, and figures.

Get your frogs hopping by introducing them to the concepts of ratio and proportion. As a class, they perform arithmetic operations using ratios then discover how they represent quantitative relationships. In groups, they write their own...

Oh that Pythagorean Theorem is so useful. Learners engage in a 45 minute learning activity that requires them to solve for missing angles and sides of a right triangle. They'll use the Pythagorean Theorem to find the rations of sides and...

Students watch the series "Unforgiveable Blackness". They analyze Jack Johnson's life to investigate the legal system and interracial relationships. They examine how segregation was threatened by peole allowing to marry ones out of their...

What better way to learn about ecosystems than by getting outside and observing them first hand? Accompanying a field trip to a local park or outdoor space, this series of collaborative activities engages children in...

Learners read the novel "Great Expectations" by Charles Dickens. In groups, they use the text to identify and describe family relationships in the book. Using this information, they compare and contrast how these relationships are...

Tenth graders investigate the relationships of pressure and volume and pressure and temperature of gases. In this gases lesson plan, 10th graders use an inflated balloon to show the relationship between volume and temperature of the air...

Students review key words used in stoichiometry such as mole, molar mass, Avogadro's number, and mass - mole relationships. They participate in a series of small experiments to explore solving stoichiometry problems in the laboratory.

What is family? Challenge your scholars to write an encompassing definition of what this word means to them. After reading "It May Be a Family Matter, But Just Try to Define Family," class members discuss the emotional issues surrounding...

Students examine the various types of family relationships. In groups, they analyze sibling rivalry, birth order, positive and negative aspects of relationships in general. To end the lesson, they complete a short quiz on this...

Class members investigate relationships between two variables in the seventh installment of a 16-part module that teaches scholars how to find and describe patterns in scatter plots. Young mathematicians consider linear/nonlinear...

Focus on inquiry-based learning in your science class with a series of activities designed for middle schoolers. A helpful packet samples four different texts, which include activities about predator-prey relationships, Earth's axis...

Examine predator-prey marine relationships through an interactive lesson design. Learners begin by studying a specific shark species and then analyze real-time shark-tracking data. They also study threats to shark populations and...

Why are right triangles so special? Pupils begin their study of right triangles by examining similar right triangles. Verifying through proofs, scholars recognize the three similar right triangles formed by drawing the altitude. Once...

Learners examine Boyle's Law by analyzing experimental results with a hands-on lesson that provides a set of four experiments that illustrate the relationship between pressure and volume of gases. Groups analyze results using...
