Emerging ecologists need a full understanding of life, from the inner workings of a cell to the complex relationships among organisms. This examination is meant to assess high schoolers after an entire year of courses on the living...

The living environment, from the interior of a cell to the complex relationships among populations, is queried in this final examination. Learners examine air pollution maps, cell diagrams, population graphs, and drawings of cells. They...

Psychologists study human relationships while ecologist study relationships between organisms in the environment. An introduction to ecology and the related vocabulary benefits scholars as they progress through the presentation and...

Elementary or middle schoolers use ratios to discover some nearly constant relationships between measurements of parts of the human body. They find and record pairs of measurements and determine the relationship between the pairs. Pupils...

Learners discover a method for determining the slope of a line by creating and comparing similar triangles. They fold coordinate grids to make three similar triangles then measure the sides to compare the relationships between the...

Streets, bridges, and intersections, oh my! Parallel lines and transversals are a present in the world around us. Learners begin by discovering the relationship of the angles formed by parallel lines and a transversal. They then...

What happens first in Tuck Everlasting? What happens after that? Prompt readers to create a timeline of the events in Natalie Babbitt's novel, detailing both story sequence and character relationships.

How does your garden grow? Use proportions to help Tim answer that question. By using their understanding of proportional relationships, pupils determine the number of seeds that will sprout. They create their own linear...

First angle measures, now segment lengths. High schoolers first measure segments formed by secants that intersect interior to a circle, secants that intersect exterior to a circle, and a secant and a tangent that intersect exterior to a...

Young scientists design a picture of a saguaro cactus that shows the cactus and some of the animals and plants that interact with it. There are many of these special relationships between plants and animals of the Sonoran Desert. Your...

Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...

Students demonstrate understanding of food chain by assuming roles of animals, playing tag, and simulating feeding relationships.

Students receive bloodstain pattern evidence from a crime scene. They answer a series of questions through inquiry, observation, measurement, and analysis. Pupils complete this challenge, by reconstructing the evidence through four...

Geometers identify and determine angle pair relationships when two parallel lines are intersected by a transversal. They review the concepts of angles by watching streaming video clips online, read definitions of lines and angles from...

Upper graders identify the surface area and attributes of figures that are measurable. They estimate, measure, and record perimeter, area, temperature change, and elapsed time, using a variety of strategies. They also determine the...

Being self-aware of personal wants, needs, and values is a big part of growing up. Here, you'll find seven different teaching options and two different introductions to a lesson on getting learners to think about their personal values....

I do, we do, you do is the method and delivery of this instructional activity on cause and effect relationships in text. Second grade readers work with their teacher, then their peers, and finally on their own to read, identify cause and...

Here is a great learning task that focuses on the development of areas in computational fluency including strategies in mental math. Young learners are guided through a list of addition expressions that help them visually understand the...

Entangle your life science class in learning with this collaborative food web activity. Using pictures of the plants and animals native to a particular ecosystem, young biologists work in small groups to construct visual...

Explore angle relationships associated with transversals. Pupils construct parallel lines with a transversal and find the measures of the angles formed. They figure out how the different angles are related before constructing...

Given a value of one trigonometric function, it is easy to determine others. Learners use the periodicity of trigonometric functions to develop properties. After studying the graphs of sine, cosine, and tangent, the lesson connects...

Scholars learn to create scatter plots and investigate any relationships that exists between the variables with a lesson that also show them that statistical relationships do not necessarily indicate a cause-and-effect...

Upcoming marine biologists consider a list of organisms residing near the Lost City hydrothermal vents and construct a food web. They compare the food web to that of a cold seep community, of which they should have previous knowledge....

Upper graders read the book Holes as a class or by themselves. In groups, they identify symbols and discuss how they are connected  among the many plots in the story. They create a timeline in which they sequence the main...
