Enhance pupil understanding of proportions and variable relationships by studying direct and inverse variation. Use the idea of a proportional relationship to teach direct variation. Then use a similar pattern to help individuals...

Discover an inverse variation pattern. A simple lesson plan design allows learners to explore a nonlinear pattern. Scholars analyze a distance, speed, and time relationship through tables and graphs. Eventually, they write an equation to...

Learners identify inverse variations. In this inverse variation lesson, students explore graphs and identify the inverse variation. They write equations for the inverse variation. Learners compare and contrast the inverse variation...

Students participate in an activity to simulate direct variation. In this oil spills on land activity, students participate in a simulation using toilet paper and vegetable oil to explore the characteristics of direct variation. They...

Hopefully you have a sensor interface for your physics class to use with graphing calculators when collecting data with a light sensor. If so, read on. Use this resource for learners to predict and then test whether or not the intensity...

Get ready to spark interest in electromagnetic radiation! This resource shares nine indelible inquiries that you can choose from to ignite understanding of spectra and the relationship between light and heat. The assessments that follow...

Students investigate patterns of inverse functions. In this algebra lesson, students represent functions with the calculator and on paper. They analyze their data and draw conclusions.

Students determine the density of different substances. In this physical science instructional activity, students rank them according to their density. They discover the relationship between volume and density.

Explore the concept of "how many times" where the word "times" is defined. Learners will determine the product and quotient in a word problem. Then use manipulatives to solve the problem. Finally, they will write in their math journals...

Fifth graders explore the inverse proportional relationship and direct proportional relationship. They complete division chart showing the inverse relationship and direct relationship. Students are shown that division problems can be...

Eighth graders participate in two data collection activities that involve direct and inverse variation. In the pre-assessment, 8th graders categorize numerical, graphical, and verbal representations as linear or nonlinear and determine...

Students, after identifying and examining the relationship of temperature and air masses in association with smog and pollution, create a temperature inversion in a long aquarium jar. They experience what happens when smog builds up and...

Do your pupils truly understand inverse operations, or is their understanding a little backward? Scholars learn the meaning of an equation in the second lesson of a four-part Algebra series. A series of activities begins with an...

Stability is key when building a bridge. Scholars explore the forces acting upon bridges through an analysis of Newton's Laws and Hooke's Law. The activity asks individuals to apply their learning by building a bridge of their own.

Young scholars solve problems involving electric charges and force. In this physics lesson, student solve word problems using addition and subtraction of vectors. They identify the direction represented by a vector as it relates to an...

Second graders, in pairs, use arrays to explore the relationship between multiplication and division.

Students conduct a series of activity that demonstrates Charles' and Boyle's Law. In this chemistry lesson, students determine the relationship among pressure, volume and temperature. They solve problems using mathematical equation.

Searching for a relatively interesting way to demonstrate Charles' Law? Here is a lesson in which pupils heat air inside a flask and then cool the flask to quickly cool the air. They make observations about what occurs during the...

Children enjoy playing with silly putty, but it provides more than just fun. Young scientists make their own silly putty using different recipes. After a bit of fun, they test and graph the viscosity of each.

Challenge scholars to prove the Pythagorean Theorem geometrically by using a cut-and-paste activity. They then must solve for the missing sides of right triangles.

Thank goodness we have calculators to compute logarithms. Pupils use calculators to create logarithmic tables to estimate values and use these tables to discover patterns (properties). The second half of the lesson has scholars use given...

Students identify variables that affect the system, and specify which variables are independent and which are dependent.

Learners determine the validity of Charles' Law. In this Charles' Law lesson plan, students measure the volumes of a gas at two different temperatures. They determine the volume at a high temperature and predict using Charles' Law what...

Students develop skills and a comfort level in interpreting economic concepts through graphic analysis.
