In this activity, students can use a light sensor to record the light intensity at various distances from a bulb. They will compare the data to an inverse square and a power law model.

This tutorial looks at the anatomy of the eye and how the sense of sight works. This is the first part of a learning module. Subsequent sections cover how images are formed and detected, the concept of accommodation where the eye adjusts...

This lesson is intended to introduce students' to Activity Center and is intended to help students develop an understanding of the formulas for braking distance and stopping distance for a variety of vehicles. Students will apply these...

Students can use a CBR 2 motion detector to measure distance and velocity. Students prepare graphs of motion and analyze them. They compare and match graphs of distance versus time and velocity versus time.

This site has explanations of the Exponential and Logarithmic Functions. The site has several examples

Eighth graders are presented with the graphs of two cars traveling. One shows distance from home versus time and the other shows speed versus time. Students are to write a description of what might be happening during each car's...

Students use the CBR 2 to gather distance and time data for various walking speeds. They observe the effect of change in direction and speed of motion on distance versus time graphs. Students interpret and analyze graphs, calculate slope...

[Free Registration/Login may be required to access all resource tools.] This lesson covers finding the domain and range of functions and sets of points. Students examine guided notes, review guided practice, watch instructional videos,...

[Free Registration/Login may be required to access all resource tools.] A review of the three major methods of solving quadratic functions for ''X'' intercepts. Students examine guided notes, review guided practice, watch instructional...

This task asks students to find a linear function that models the relationship between water depth and distance across a channel at water level. After finding the equation, they have to verbalize the meaning of the slope and intercept of...

Site provides exercises for graphing on the coordinate plane including distance formula, midpoint formula, graphs of equations, and graphing using a calculator.

This site is a lesson plan on construction of a parabola using the definition. Geometer's Sketch Pad software is beneficial for the lesson. Through the lesson students develop gemetric constructions of parabolas, use the distance formula...

In this lesson, students can use the CBR ranger to model walking distance over time. They will walk away from the sensor, back towards the sensor and finally away from the sensor over an interval of 10 seconds. The result should be 3...

For this task, students write expressions that describe the relationship between quantities. The task looks at the amount of gas produced by a given number of barrels of crude oil, the number of miles a vehicle can drive on a quantity of...

This site is a comprehensive review of algebraic basics including equations, the distributive law, the equation of a straight line, quadratic equations, polynomials, the difference of squares, the Pythagorean distance formula, and...

An algebra "cheat sheet" to use as a reference when completing algebra homework. Lists basic facts, properties, operations, formulas, and functions, as well as common errors.

In this activity, students walk in front of a calculator-based ranger CBR and try to match a distance-time graph. They examine the rate of change, and analyze and interpret the graph of a function.

Students model the data from the motion of a pendulum by a periodic function. They relate its parameters to the time for one period, the distance it is pulled back, and its distance from the motion detector.

In this activity, students take distance readings as they walk in front of a CBR. They apply the properties of a linear function to develop a model for the motion and interpret the values used in the model. Students learn to graph...

Here's a group activity your students can do to learn about rational functions. Students will use properties of reflections together with measuring tapes, mirrors, and masking tape to find a function that relates height of a reflection...

In this activity, students create a situation that produces linear behavior by stepping heel to toe and taking distance readings as each step is taken. Students then apply the properties of a linear function to develop a model for motion.

In this activity, students collect information about the stops made, time taken, and distance covered by a train on one of Amtrak's routes. They find a mathematical model that can best track the train. Students understand concepts...

For this task, students are asked to calculate the height above sea level of a lamp on top of a lighthouse that is visible to a boat, and to examine two other interpretations of the distance from the lighthouse to the boat. Aligns with...

In this activity, students' will use a force sensor and a motion detector to study the relationship between the force applied to a rubber band and the distance to which it stretches. They will then model force versus strech data with a...
