Graph and solve linear equations in two variables. The class relates the concepts of linear equations to the real world.

Students experiment with point graphs. In this math lesson, students are divided into groups and perform an experiment to see how high a ball bounces, recording their results on a point graph. Students then answer provided questions.

Students calculate fixed and variable costs. For 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.

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 lesson allows for the discussion of independent and dependent variables, as...

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.

Sixth graders set up a pendulum experiment deciding which variable to manipulate (length of string or weight on the string). They create a hypothesis, collect necessary equipment, and write out each step of their experiment. They then...

Young scholars experiment with graphing. In this graphing introduction instructional activity, students complete four activities: 1) a bar graph based on class birthdays 2) an estimation graph of the raisins in raisin bread 3) another...

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...

Students conduct an experiment to determine the percentage of sugar in various types of gum. They weigh the gum after chewing it to determine the amount of mass lost from each piece of gum, analyze the data, and create a graph of the...

Middle schoolers roll a ball down a plank and measure the distance it travels. Students graph the distances the ball travels as they change the height of the incline (increase slope).

Young scholars study the concepts of motion, velocity, and acceleration through graphing their own movement using LoggerPro. They explain the difference between speed and velocity using the weather vane example. They discover the...

Students review the meaning of control and variables, and state difference between dependent and independent variables. They complete a worksheet with the definitions and complete problems that show their understanding.

Students investigate variables that influence the bouncing of balls.  In this exploratory lesson students observe how the manipulated and control variable are correlated by graphing the data.

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

Students develop an independent procedure to investigate the germination of two types of seeds. Students must construct data tables or charts to record observations and results, graph the data, and analyze the data.

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...

Fifth graders are introduced to the atlatl system and how to test and control variables. In groups, they use the Internet to research how the system has changed over time. They test various variables and record their results in a graph...

High schoolers graph data on fetal and infant mortality rates collected by the Centers for Disease Control and Prevention. They identify trends in the data and propose potential causes for the trends.

Students determine the concentration of an unknown solution. This task assesses students' abilities to state hypothesis, develop procedures for investigation, plan for recording and organizing observations and data, collect data, create...

Students identify different types of functions and units of measurements. In this statistics instructional activity, students will collect data, graph their data and make predictions about their data. They plot a linear regression...

Students design and carry out an experiment according to the scientific method. The experiment must test the effects of time and concentration on the rate of diffusion of potassium permanganate into potato cubes. After performing the...

This is one in several lessons that explore the relationship between temperature and phase changes of water. After some discussion, elementary physical scientists place wet paper toweling on a hot and a room-temperature water bag...

Students designs and conduct a scientific experiment that identifies the problem, distinguishes manipulated, responding and controlled variables, collects, analyzes and communicates data, and makes valid inferences and conclusions.
