Students develop the concept of supply and demand. In this economics lesson, students listen to a lecture and take notes on supply and demand. Students create a coherent set of notes about supply and demand.

Students systemically determine the concept that the waste items placed in a "yes" category are biodegradable and those in the "no" category are not. This activity is a motivating way to introduce a unit on wastes by having students use...

Students complete a word problem to determine the cost of gasoline per mile of their virtual field trip. They determine the travel time and gasoline costs for two routes and record the information on a data sheet. They check their work...

Students distinguish between possible and impossible graphs of functions, and to learn why some graphs are impossible. They have practiced plotting functions on the Cartesian coordinate plane

Students use the lesson, "Squirt", to support students' development of multiplicative thinking. Squirt encourages students to anticipate multiplicative measurement relationships, e.g. three measures of A fit in B, by partially filling a...

Ninth graders investigate relationship between the temperature and concentration of dissolved oxygen in water. They examine how pollution and other natural influences can cause the parameters to change. In groups, 9th graders collect...

Young scholars calculate angular displacement, velocity and acceleration of gyrocopters. For this physics lesson, students compare data taken from 3 different gyrocopters. They explain how differences in construction material affect...

Eleventh graders compare the amount of sugar sand present in tree sap. In this environmental science instructional activity, 11th graders measure different tree circumference. They prepare a report and share findings in class.

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

In this chemical equilibrium worksheet, students review hydration, dissociation, and colligative properties. Students also review Le Chatelier's principle. This worksheet has 15 short answer questions and 12 problems to solve.

Students explore how to use graphing calculators.

Imaginary numbers are a real thing. Scholars learn about complex numbers, real numbers, and imaginary numbers. They classify given numbers as strictly complex, strictly real, or strictly imaginary in an individual or group activity.

Legos in science class? Watch your pupils fall in love with this activity. After learning to measure potential and kinetic energy, young scientists create their own ramps using Lego Mindstorm sensors and software.

Addition and subtraction are studied in this math instructional activity. Upper graders add and subtract whole numbers up to 1,000 with and without regrouping.

Students explore inequalities. For this Algebra I lesson, students solve and graph linear inequalities involving addition, subtraction, multiplication, or division.  Students use inequalities to solve and graph real-world problems.

Sixth graders convert customary linear measurements. They explore using ratios to convert from inches to feet, ounces to pounds, etc. In groups, 6th graders complete conversions. They explain to the class how to solve their problems.

Middle schoolers practice plotting functions on the Cartesian coordinate plane while participating in a discussion about the Possible Or Not worksheet/activity. Students also use the Impossible Graphs worksheet to practice reading a...

In this equilibrium and water chemistry worksheet, students solve twenty problems related to acids and bases, equilibrium and water.

Students examine stoichiometry. In this chemical reaction and mole activity, students complete an experiment based on readiness levels to explore that changes are quantified in chemical reactions.

Students analyze data from a virtual field trip to Michigan. They conduct Internet research on mileage and travel time between cities, calculate and compare fuel costs, and research and calculate lodging, activities, and meal costs.

Students use shapes and manipulatives to demonstrate patterns. In this patterns lesson plan, students also break up patterns to identify a pattern unit.

In this math activity, students find the answers to the functions that includes integration and trigonometry. They use the examples for help with the special functions.

In this entropy worksheet, students calculate the change in entropy and rank absolute molar entropies. This worksheet has 12 problems to solve.

Students determine eigenvectors and eigenvalues for a matrix. Students diagonalize a matrix. Similar matrices are defined. Determinant formula is given for an degree n polynomial.
