I get a charge out of this. In order to learn how a generator works, groups build and test one in this ninth lesson of the series. The generators are tested at low speed and high speed to determine the watt output and whether they have...

What are some simple uses for an electromagnet? Scholars explore the electromagnetic circuitry in a doorbell through an interesting simulation. They control the core material, number of loops, amount of current, and strength in a spring....

Is this resource a great way for your class to observe bonding between oxygen and hydrogen? OH yeah! Scholars learn about the changes in kinetic and potential energy as molecules of oxygen and hydrogen interact. Kinetic, potential, and...

Does the accuracy of the first guess make a difference down the line? Learners investigate the effects of the iterative process of finding roots, using Newton's Method. By moving the initial guess of a root on a graph, pupils observe the...

Control the spread of a contagious disease. An applet allows pupils to run a simulation on the spread of a disease. Rules govern how the disease is spread and the length of time it takes to recover. Learners view the spread visually and...

In the age of the Internet, are libraries still important? A collection of sources, part of a set of sample free-response questions from the AP® English Language and Composition exam, discuss that question. A variety of sources,...

Keep moving along a curve. Two items in the set of released free-response questions from the 2010 AP® Calculus BC exam involve movement along a graph. One involves particle motion along a polar curve while the other uses a squirrel...

How do humans affect ecosystems? Learners read two articles and interpret a graph to develop essays on the human impact on ecosystems. They read about human impact on tigers and manatees as a basis for their overarching papers.

Falling off a bridge might not sound like your idea of a good math problem, but incorporating the final scene of Les Misérables is sure to spark interest. The goal is to use the time Javert fell off the bridge to determine how...

Carryout the lesson to determine the cost of pizza toppings from a Domino's Pizza® website while creating a linear model. Learners look through real data—and even create their own pizza—to determine the cost of each topping. They...

A baseball trajectory and a parabola seem to make the best pair in real-world quadratic applications. Here is a current baseball resource with questions, discussions, and explorations regarding a quadratic function and home run...

An activity around linear equations, slope, and intercept is here for you. In it, young mathematicians engage in a whole-class activity while the teacher uses the overhead projector graphing calculator. This activity also focuses on...

Fourth graders graph cars according to their colors. They complete the graph including a title, scale, x-axis, and y-axis. Students collect the data and choose the type of graph to be made.

Students make equations from everyday data. They create a graph from the equations. Students predict and analyze the results. Students complete the second scenario on their own and turn in their handout.

Using a graphing calculator, construct a graph and find solutions to quadratic equations. Observe additional methods of solving quadratic equations. Independently, solve solutions by using the discriminant.

Get ready for Calculus! The class solves equations, graphs a relation defined parametrically, and gives the parametric equation for the inverse relation. They then identify the geometric relationship between two graphs.

Here is a resource that helps your algebra learners understand the connection between the graph of two lines, the equations of lines, and the solutions and intersecting points of lines. It would make a great assessment question, but can...

Fourth graders sort seeds and predict what conditions are needed for them to germinate. They keep the seeds moist, observe and measure their growth and graph the results. As the seeds start to grow students compare and contrast the each...

Eighth graders do a research project on a particular species of Atlantic seafood and record and graph information pertaining to commercial landings of that species of seafood. They use a website and an Appleworks spreadsheet.

High schoolers factor polynomials and linear functions and apply concepts of the fundamental theorem of algebra to solve problems. They graph their solutions and analyze the graph.

Students make a box and whiskers plot using the TI-73 graphing calculator. Each student would have their own calculator but they would work in small groups of two or three to help each other enter the data and make the plots.

Students design a rectangular box without a lid that has the largest possible volume using the supplied sheet of centimeter graph paper. They work in groups to construct different size boxes to determine the largest possible volume and...

Most of this lesson is spent working on the "Bathymetry Worksheet." It includes a graph of the changes in sea level over the past 150,000 years and a bathymetric map of changes in an imaginary coastline over time. Participants answer...

Fourth graders examine the types of garbage that they collect on the playground. They collect the information in a spreadsheet and create a graph that displays the number of types of trash found. They design and monitor a playground...
