Learners recognize dependent and independent variables in an experiment by practicing manipulation of variables; students practice designing experiments that contain the two types of variables.

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...

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.

Is it easy to make snow? Scholars use critical thinking skills as they investigate the concept of polymers by making snow. The class tests several different variables and takes measurements over the course of several days. They then...

Students predict and test different variables that would effect sugar cubes dissolving in water. In this dissolving lesson plan, students have 4 petri dishes with 4 different variations of sugar cubes and water. They predict which will...

Investigate the relationship between independent and dependent variables. Individuals begin by identifying independent and dependent variables from different problem situations. Then, using specific guidelines, they create posters...

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.

While pupils design their own lab experiments, they will not form a new species. Scholars take their materials and design an experiment regarding reaction rates. 

Fifth graders plant and take care of a lima bean plant and make predictions on its growth.  In this science lesson, 5th graders chart their records and make conclusions about their experiment. 

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...

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.

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...

Study velocity while examining graphical representations. As scholars work with the animation, they discover the effect the height of an incline has on the velocity of the biker. They make conclusions about the slope of the...

A set of instructions and a 100-point grading rubric have been designed for writing lab reports. Appropriate for middle schoolers, this lays out what to include for each of the six steps in the scientific method: title, hypothesis,...

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....

Middle schoolers investigate a variety of animal behaviors, examine various modes of animal communication, and develop a catalog analyzing, interpreting, and reporting their results.

Learners 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...

Tenth graders investigate the carbon monoxide level at a fixed latitude to determine if there is a relationship to population density. They download data sets and generate a graph, and find locations using the Earth's coordinate system....

Middle schoolers analyze graphs to determine relationships between variables and rates of change. They determine the basic concepts about static reaction forces. They determine the slope and equation of a line.

Students examine the environmental impact of global warming. In this environmental science lesson, students design and conduct an experiment about the effect of temperature on paramecia. They write a lab report about their experiment.

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 explore the concept of hardness. In this physical science lesson plan, students will be using clay heated at different temperatures to study hardness based on the indention left. Students will also be identifying the variables...

Students investigate friction by manipulating some of the variables affecting it. In this inquiry lesson, students design their own experiment. They create a video about it and share it to class.

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