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.

This interesting document suggests nine different activities for shedding light on photovoltaic cells. A bit of background information is furnished for you, as well as many, many resource links. Listed for each activity are a learning...

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

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...

Everything you need to teach a instructional activity 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...

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...

Time to experiment with mathematics! Learners study experimental design and how randomization applies. They emphasize the difference between random selection and random assignment and how both are important to the validation of the...

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

Young investigators conduct an experiment using the scientific method. They see how many drops of water fit on a coin; have them conduct several different trials. This involves making a hypothesis, looking at controls, and introducing...

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.

Students evaluate a hypothetical experimental design and attempt to improve upon it. In this scientific method lesson, students are presented with an experiment and are instructed to determine its flaws. They conduct their own...

Fourth graders make a detailed observations about non-native and native grasses. They define reasonable policies that they expect to follow while working in the CRWA. Students list, in small groups, two treatments that have been used in...

Students investigate transition metals and their oxidation states. In this complex ion and oxidation states lesson plan, students use 6 transition metals and mix them with ligand solutions and oxidizing agents separately. They test their...

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.

Provide young biologists with everything they need to excel in the study of lymphatics, the nervous system, hormones, cellular division, and more! Pupils utilize the workbook, complete with end-of-chapter assessment worksheets, to...

Students participate in a laboratory investigation in which they observe the effect of temperature and pH on enzyme activity. Students also examine exposure to heavy metal ions and the effect that may have on enzyme activity.

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...

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. 

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 reseach the different types of soil erosion and ways to control it in this series of activities.

Learners collect and identify plant species from campus, create a home herbarium, and compare with the plant species from school.

When going for distance, does it make a difference at what angle you launch the rocket? Teams of three launch foam rockets, varying the launch angle and determining how far they flew. After conducting the series of flights three times,...

Students 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...
