Elementary-aged scientists discover that all matter has mass. They are shown the difference between mass and weight, and learn how to calculate mass using the appropriate tools and methods. The scientific method is used while estimating...

Students use a hypothetical scenario to investigate inhalation of an airborne pollutant and ingestion of a waterborne pollutant. They work in pairs, investigating differences in overall exposure to contaminants by calculating inhalation...

Designed by School Power...NaturallySM, this lesson familiarizes advanced earth science and physics learners about the variables that affect our supply of solar energy. They examine gas spectra and perform calculations. There is an...

Middle schoolers, working with their parents, calculate and complete five word problems associated with multiplying and dividing decimals. Students research the current Federal minimum wage at the library or on the Internet.

A bouncing ball serves as more than entertainment when learning to apply quadratic functions to real-world events. This is the second of a two-part lesson, which can also be accessed from the website. The instructions say to measure the...

Pupils take photos from a given distance and determine the height of the person using a scale factor. Pupils calculate the ratio of student actual height to student photo height. They take pictures from 3 different distances to see if...

Students use optimization concepts to design their own container. In this optimization lesson plan, students understand how the optimization concept is critical in calculus and why products are packaged the way they are.

Algebra learners look at equivalent expressions in the context of three different operations: division, squaring, and absolute value.  In comparing these values, they will identity when expressions are equivalent. 

Here is a set of lessons that explore conics in a number of different ways. Starting with modeling how a conic is produced by the way a plane cuts the cone, to solving complex word problems, algebra learners progress through a series of...

Everyone loves a sale, and this worksheet allows learners to calculate which sale is more rewarding. The activity can be adapted for different thinking contexts. The answer key describes different answer choices, some being higher...

We are used to finding the area of a circle by plugging the radius into an equation. Here, learners are required to go further to find multiple areas and calculate the difference. They must detect a pattern in order to figure out the...

Who's ready for the dance? When two middle schools combine for a dance, your learners' job is to calculate the ratio of girls attending. Provided with three different solutions, you can choose from setting up a ratio, linear equation, or...

Taxi! Have your travelers figure out how far they can go in a taxi for $10.00. They must account for the mileage rate and tip in their calculation. They can set up a table or make an equation to solve for the exact mileage they can...

The problem seems simple: find the area of the equilateral triangle whose sides are each length 1. In fact, this same problem is solved in 8th grade, addressing a different Common Core standard, using the formula for area of a triangle...

What happens when you combine 6.022 times 10 to the 23 piles of dirt into one? You make a mountain out of a mole hill. Scholars use dehydration to obtain percent composition and then calculate the molarity of the original...

At some point, everyone has been under pressure—even Dalton! Explore Dalton's law of partial pressures with young chemists as they measure the volume of air extracted from a sample compared to its original volume. Class...

Don't use an average resource ... use this one. As a middle school assessment task, learners first determine mean, median, and mode of salaries given in a frequency table. They then investigate how a change in one value changes the...

What figure is formed by connecting the midpoints of the sides of a quadrilateral? The geometry assessment task has class members work through the process of determining the figure inscribed in a quadrilateral. Pupils use geometric...

Is there a better way to display data to analyze it? Pupils represent data in a variety of ways using number lines, coordinate graphs, and tables. They determine that certain displays work with different types of data and use...

Squares can be magic. Pupils use their knowledge of addition of positive and negative rational numbers to create a 3 X 3 magic square where the sums are 1. Scholars create addition and multiplication expressions with a set of rational...

Circles, circles, everywhere! Pupils learn all about circles, central angles, inscribed angles, circle theorems, arc length, area of sectors, and radian measure using a set of 12 lessons. They then discover volume formulas through...

Ninth graders produce a projected, pinhole image of the sun and from measurement of the image and projection distance, calculate the actual size of the sun. They estimate the sun's apparent brightness from different planet.

Students examine the process of drawing a picture to scale. They analyze and discuss real-life blueprints for a house, and create a scale drawing of an original invention using calculators and rulers.

Learners calculate the speed of an object, by measuring the amount of time it takes to cover a given distance, and then divide: speed=distance/time. However, the object may not have been moving at a constant rate over the given distance....
