Students study the variables that affect the Earth's albedo.  In this environmental data analysis lesson students interpret and graph information and calculate changes. 

Discuss an article about families affected by genetic disorders and their decisions about whether or not to evaluate their own genetic information. Investigate four different inherited disorders. Participate in a probability exercise....

Become familiar with the basic concepts of inheritance. Your junior high learners work through mulitple examples of crosses and calculate probabilities of trait occurance. The explain the concept that each parent contributes one half of...

Wow! What a lesson plan! Six terrific activities are described in great detail, in this 31-page document! Learners will model and explain cloud formation, sketch and identify certain cloud types, calculate and compare incoming and...

Two laboratory problems are put forth for chemistry students. They are to plan and carry out an experiment that will answer each of the questions. The first asks them to investigate a relationship between the surface area of a potato and...

With Earth Day quickly approaching, as well as many science fairs, why not challenge your class to investigate geothermal energy or other renewable energy resources? There are five driving questions explored in depth here, as well as...

Take young mathematicians on an exploration of the world of 3-D geometry with this seven-lesson unit. After first defining the terms perimeter, area, and volume and how they apply to the real world, students continue on...

The United States is the world's largest producer of biofuel. During an in-class investigation, young scientists produce their own biodiesel. They burn a sample of it to determine the heat of combustion. Then they discuss the...

Pupils explore the midsegment of a triangle in the geometry instructional activity. They draw and measure the segment joining the midpoints of the two sides of a triangle and compare its length to the length of the third side of the...

High schoolers explore the concept of right triangles as they construct a right triangle using Cabri Jr. Learners find the midpoint of the hypotenuse and construct a line from the midpoint to the vertex of the right angle. They then...

Learners investigate concept of matrices through iteration in this probability lesson. They investigate probability by creating a lesson based on a famous painting. This assignment contains extensions to the...

Young learners apply divisibility rules to determine if a number is a factor of another number. They discuss what numbers are factors of another number and identify patterns using divisibility rules.

Pupils explore quadratic functions in this algebra lesson. They investigate transformation of quadratic functions using the TI calculator. They use the vertex form for this lesson.

Your class can investigate the weather through an experiment. In this chemistry lesson, learners collect data on air pressure and relate it to the weather. They collect data with the TI containing a barometer probe.

Learners collect and analyze voltage data. Then, they investigate exponential functions using the TI and a Voltage Probe and graph their data and analyze it using a table.

Teaching elastic forces in your physics class is a snap with this resource! Scholars compare the stretch of rubber bands with differing width, then measure the stretch of a spring and calculate force. In a whole-class experiment, wire is...

Given a variety of rocks, junior geologists calculate densities and correlate them to Earth's layers. As a simulation of continental crust, they experiment with how materials of differing density float in water. Finally, they...

Students examine data to investigate the impact of lead shot pellets on waterfowl populations. They graph their findings and discover how lead in ingested by birds and poisons them. As an extension, students research legislation and...

Of particular interest to a group of business and finance pupils, this instructional activity explores depreciation of automobile values by comparing the double declining balance to the straight line method. Mostly this is done through a...

Who knew quilting would be so mathematical? Introduce linear equations and graphing while working with the lines of pre-designed quilts. Use the parts of the design to calculate the slope of the linear segments. The project...

Through the analysis of paper chromatography to separate ink from the pen found at the crime scene, learners analyze the different stains and through calculations determine the thief. 

For this math worksheet, students learn the concept of factorials and how to calculate them. Students first do a factorial investigation with crayons. Then students learn to compute larger factorials in more difficult problems.

Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions...

Mathematicians use a symmetric secant line to prove the derivative at a point. In this trigonometry lesson, students create secant lines on the navigator to analyze the derivative. They move the lines around and make observations.
