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 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....

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

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

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...

Students 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 difference...

In this lab design and lab skills worksheet, learners answer questions about experimental design including finding variables, determining controls, and graphing data. They answer questions about microscopy and label the parts of a...

Andree Walker thought of everything when he wrote this resource. It includes a detailed list of materials and background information links for the teacher. In addition, it has procedures, a macroinvertebrate identification key, and tally...

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 experiment with point graphs. In this math lesson plan, 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.

Caffeine affects your heart rate — or does it? Learners study experimental design while conducting their own experiment. They collect heart rate data after drinking a caffeinated beverage, create a box plot, and draw conclusions....

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...

Learners use a model experiment to complete an experiment on yeast. In groups, they identify the independent and dependent variables and use the scientific method to complete the activity. They record their observations and discuss them...

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

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...

Here is a complete activity in which young biologists or ecologists test the pH, dissolved oxygen, turbidity and temperature of stream water. The class visits an actual stream and makes observations of the site. They use scientific...

Research the impact that changes in biotic or abiotic factors might have on an ecosystem. Debate for or against the changes and take action in the community. This resource ideally follows stream studies that young ecologists may have...

Students 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.

Learners 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.

Examine parts of an expression in this algebra lesson. Ninth graders identify the properties of the coefficient and their behavior to the graph. They graph the equation on a TI to see their results.

Through exploration of linear programming through graphs and equations of inequalities, young scholars relate linear programming to real life scenarios, such as business. Graphing and shading is also part of this exercise.

Watch as your class makes the transition from pupils to researchers! A well-designed instructional activity has scholars pick a solar wind characteristic to research. They then collect and analyze official data from the LANL...

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...
