In this activity, students' will use a motion detector to observe the effect of speeding up, slowing down, and moving at a constant rate on a Distance versus Time plot.

Based off of the hit television show NUMB3RS, this simulation has students model the Four-Bug Problem in order to see the general concept of pursuit curves. Each student takes on the role of a bug, and are placed at each corner of a...

Different types of hot dogs will cool at different rates after they have been cooked. This activity takes the first steps in investigating this phenomenon by measuring the rate that a warmed hot dog cools. Students can compare the...

In this activity, students begin to investigate linear regression by looking at the effect of outliers on the regression line. The worksheet is interactive.

This probeware version of the Skills Practice Lab Brightness of Light from the chapter Light and Reflection uses a light probe to measure the intensity of light at different distances from a light source.

From Shore to Sea: Examine the relationship between kelp plants and sea urchins, and the effects of severe El Nino events on their populations by using data collected by researchers at Johnson's Lee South on the island of Santa Rosa.

Based off of the hit television show NUMB3RS, this lesson introduces students to elementary game theory. The lesson is framed in the context of criminal who must get off at one of two subway stops -- will the officer choose the same stop...

Based off of the hit television show NUMB3RS, this lesson extends upon the classic Handshake Problem (in which everyone at a party shakes hands with everyone else -- how many handshakes were there?) by not allowing guests to shakes hands...

Different surfaces absorb and radiate radiation at different rates. In this activity you will analyze the absorption and radiation rates of two surfaces by monitoring the temperature changes of each of them.

When you start this activity, students receive a Venn diagram of real number sets (natural, whole, integer, rational, irrational)on their calculator. This same diagram is projected on the Activity Center screen at the front of the room....

Students take measurements of individual's wing span and height and create a coordinate graph. The activity should include at least three different grade levels. Students submit an equation through "Activity Center" and the class...

This activity takes a discontinuous, piecewise defined function and redefines it to make it continuous and differentiable at the point of discontinuity.

In this activity, students will find both the kinetic and potential energies as the cart rolls down the ramp. They will find the sum of the two energies, and show that this value is constant at all times.

This activity will allow young children to explore number patterns and relationships while introducing the calculator at the same time.

This activity shows students the power of finite and infinite series. It can be used as an introduction to infinite series provided that the student is adept at using the sigma notation to denote such series. (Continued: See before the...

Groups of 4 to 5 students follow teacher prompts to enter one part of a number (ex: 6 thousands), and then the next student adds the next part until the entire number is built, one digit at a time. Self-checking!

In this activity, students will collect temperature and light readings over a 25 hour time period and explore relationships between and within the data. They will discover the relationships of temperature with sunrise and sunset and look...

Based off of the hit television show NUMB3RS, this lesson gives students further insight into the various spirals that can be graphed using polar equations. While the lesson assumes that students already have some background with polar...

Based off of the hit television show NUMB3RS, this activity shows students how money invested at different interest rates grow differently. The lesson focuses on aspects of interest such as compounding, length of time between...

Students take a numerical and tabular look at finding the maximum value of an open box constructed by folding a rectangular sheet of material with cutout square corners. They also understand the concepts of independent and dependent...

Rainforests at the Crossroads: Measure the CO2 level in a bottle that contains spinach leaves when it is exposed to light. Then collect CO2 data and observe the effects of photosynthesis as you add leaves in the bottle.

Based off of the hit television show NUMB3RS, this lesson, designed for upper-level high school students, has students linearize the data describing the force of a magnet at various distances. While it is assumed students already know...

Students learn to use manipulatives and calculators to explore what happens when they change one number at a time in a subtraction number sentence. They record and develop the pattern that develops.

In this activity, Students can use a Magnetic Field Sensor to measure the magnetic field of the Earth and to determine magnetic north. They will also calculate the magnetic inclination and declination at their location.
