Seventh graders identify variables and controls in a paper airplane investigation. In this scientific method lesson, 7th graders conduct an experiment to determine the variables that affect the flight of paper airplanes. They design an...

Everything you need to teach a lesson on two variable linear equations is right here. Objective, vocabulary, tech tips videos, and multiple downloadable files are all included. Learners will use the TI-Nspire technology to determine the...

If you discover an unknown powder, how do you determine if it is safe? Lesson uses four different tests to identify the properties of various powders that appear the same. Then scholars get an unknown powder and have to determine which...

Students investigate the fixed and variable costs that entrepreneurs face. They examine how entrepreneurs identify and control their costs in order to make a profit by completing a number of included activities.

Students calculate fixed and variable costs. In this costs lesson, students read a case study about an entrepreneur and her business costs. Individuals complete the provided worksheets to find costs and make related business decisions....

Here is an engaging lesson on solving equations with two variables. Have the class rewrite linear equations in the slope intercept form, y=mx + b. They graph the lines using the slope and y-intercepts.

Middle schoolers examine the effects of variables. They view a video which introduces the concepts, take part in an internet-based activity, then engage in a hands-on activity which allows them to practice what they have been studying.

Using rates from a rental car company, young mathematicians graph data, explore linear relationships, and discuss the role of slope and the y-intercept. This instructional activity allows for the discussion of independent and dependent...

Students identify and apply the scientific method through an experiment with popcorn. Then they identify what independent, dependent, and control variables are and create a list of different variables that affect popcorn popping....

Students solve equations by writing expressions. In this algebra lesson, students identify the different values for each variable. They use the navigator to see how to solve equations.

Why do experiments require a control? Guide scholars through designing an experiment to see what they can do to evaporate water faster with a lesson that stresses the importance of controlling all variables. The second activity...

There is a solvent called aqua regis that can dissolve gold! After observing a solubility demonstration, groups receive four known crystals and one unknown. Based on the demo, they design an experiment to determine the identity of the...

Seventh graders examine a teacher-created database and identify specific variables and develop hypothesis statements as to their possible effect. They create a summary statement either proving or disproving their hypothesis.

Students solve equations with variables on both sides of the equations. In this algebra instructional activity, students use addition, subtraction, multiplication and division to solve problems. They combine like terms and identify the...

Students describe some common pests. They study three levels of pest control from the IPM pyramid.

Students identify the types of transformations in their lives. As a class, they determine the ones they have control over and which ones they do not. They practice solving problems in math and oral communication that they are faced with...

Ninth graders conduct experiments to determine what affects the rate of a pendulum's swing. Working in small groups, they identify an independent variable to study and create an experiment to test their hypothesis. When tests are...

High schoolers investigate perimeter patterns formed by a hexagon and a triangle. They will identify the dependent and independent variable and write a function for the relationship.

Students will work in groups to design and conduct an experiment to identify amino acids found in an unknown solution. This lesson is taught in three sections: (1) Introduction to chromatography (2) Experimental design session (3)...

Students experiment to determine which bottle of soda has more dissolved carbon dioxide. In this solutions lesson, students use the scientific method to test the amount of carbon dioxide in bottles of soda. They identify and explain the...

Students watch a video show how to identify the independent variable, dependent variable and controls in an experiment; and design experiments that use controls to isolate a single independent variable and measure the resulting dependent...

Putting glow sticks in the freezer makes them last longer, but why is that? Lesson focuses on how temperature impacts the rate of a chemical reaction. It begins with a teacher demonstration, then scholars design their own experiments...

Learners experiment bubbles. In this scientific method lesson, students identify variables used in proper experiment design. Learners conduct experiments with different brands of dish-washing detergent to determine which brand makes the...

The scientific method keeps you from believing only what you want to believe — it expands your mind. The lesson introduces the eight steps in the scientific process and how to design an experiment to biology scholars. Live insects...
