Ancient people used musical pipes as early as the third millennium BCE. Young scientists explore the workings of musical pipes to better understand the relationship with frequency, length of pipe, and sound waves. They determine the...

Graphing by hand does have its advantages. The 19th installment of a 35-part module prompts pupils to use skills from previous lessons to graph exponential and logarithmic functions. They reflect each function type over a diagonal line...

Introducing inverse functions! The 20th installment of a 35-part lesson encourages scholars to learn the definition of inverse functions and how to find them. The lesson considers all types of functions, not just exponential and...

Scientists need to have mastered algebraic slope-intercept concepts in order for this lesson to be effective. They will measure and graph solar panel output as a function of the amount of radiation striking it, discovering that there is...

Pupils use the Internet to research current and past snowpack levels and river gauging station readings. They determine the relationship between snowpack and river flow. They predict future river flow.

Right angles, acute angles, obtuse angles, central angles, inscribed angles: how many types of angles are there? Learners first investigate definitions of inscribed angles, central angles, and intercepted arcs. The majority of the...

Is there a relationship between powers and roots? Here is a lesson that asks individuals to examine the graphical relationship. Pupils create a table of values and then graph a square root and quadratic equation. They repeat the process...

Augment a unit on parabolas with an instructive math activity. Pupils graph parabolas by examining the relationship between the focus and directrix. 

Float like a butterfly, sting like a bee, check out wing shapes for common ancestry! Beginning biologists compare wings as analogous structures and discover that environment influences evolution of adaptations. A third activity relies on...

Can an equation have an infinite number of solutions? Allow your class to discover the relationship between the input and output variables in a two-variable equation. Class members explore the concept through tables and graphs and...

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...

Classmates apply midpoint concepts by leapfrogging around the complex plane. The 12th lesson in a 32 segment unit, asks pupils to apply distances and midpoints in relationship to two complex numbers. The class develops a formula to find...

Discover the connection between vectors and translations. Through the lesson plan, learners see the strong relationship between vectors, matrices, and translations. Their inquiries begin in the two-dimensional plane and then progress to...

Discover how trend lines can be useful in understanding relationships between variables with a lesson that covers how to informally fit a trend line to model a relationship given in a scatter plot. Scholars use the trend line to make...

Give your pupils a front row seat at the biggest light show in the sky this year! In addition to admiring the total solar eclipse, young astronomers can explain the phenomenon with a little help from an inquiry-based lesson. The focus of...

Think outside the box - and think about education beyond the classroom walls - with a resource that has your critical thinkers watching a video about a nursery in Scotland that lets youngsters roam wild in a forest....

This is one in several lessons that explore the relationship between temperature and phase changes of water. After some discussion, elementary physical scientists place wet paper toweling on a hot and a room-temperature water bag...

Learners examine folk’s tales for Cause and Effect. In this literature lesson, students read "The Origin of Fire" and "The Origin of Medicine” and look for cause and effect. They use a TI Navigator to write down their findings.

Discover an inverse variation pattern. A simple lesson plan design allows learners to explore a nonlinear pattern. Scholars analyze a distance, speed, and time relationship through tables and graphs. Eventually, they write an equation to...

Demonstrate linear and quadratic functions through contextual modeling. Young mathematicians explore both types of functions by analyzing their key features. They then relate these key features to the contextual relationship the function...

Fifth graders explore the relationship between potential energy and kinetic energy.  In this energy lesson, 5th graders examine objects and describe  potential and kinetic energy of the objects. Students complete two worksheets.

Students discover that olfaction elicits memory associations. They investigate how olfaction compares to other sensory modalities in the formation of memories. This is a hands-on lab activity guaranteed to build memories in your students!

Students identify variables that affect the system, and specify which variables are independent and which are dependent.

Students begin the lesson by developing a map of Kelsey Island by following specific instructions. In groups, they are given a block of ice in which they tie a rope around and drag over various rocks for different distances. They...
