Middle school scientists bathe in Bikini Bottom with SpongeBob and friends. They define steps in the scientific method. They identify independent variables, dependent variables, and the control for science experiments being carried out...

Most teens like to sleep in as late as possible, so testing the fastest way to get to school sounds like a great idea. A presentation walks through how to identify the controls, independent variables, and dependent variables in setting...

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

For this scientific variables on-line worksheet, students will be given a statement about a specific experiment. Students will use their mouse to circle the independent variable, underline the dependent variable, and box the controlled...

Middle schoolers explore the concepts that enable them to design and conduct sound scientific experiments. They critique a faulty experiment and become familiar with some of the criteria of a good experiment. They conduct their own...

Mint candies are good for more than just one's breath. Using basic materials such as mint candies, straws, index cards, and Popsicle sticks, scholars create race cars that meet a given budget as well as design constraints. They perform...

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

Students are able to name one kind of harmful bacteria and why it hurts us and also name one kind of helpful bacteria and how we use it. They describe the process of growing bacterial cultures in a lab. Students create a reasonable...

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...

Which modification is the best? Using the scientific method, pairs determine the effects of each control surface on the distance of a glider's flight. The activity, section 16 in a 22-part unit on aviation, allows pupils to gain a better...

In this control and experimental variables worksheet, students read about the variables in an experiment and practice identifying each in 2 experiments. Students analyze the data in an experiment, identify the hypothesis and the...

In this experiment worksheet, students give examples of independent, dependent, and controlled variables. This worksheet is a graphic organizer.

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...

In this variables in experiments learning exercise, students read about control variables and experimental variables before they respond to 15 graphic organizer and short answer questions.

In this variables learning exercise, students are given seven experiments that they read and identify the independent variable, dependent variable, control group and standardizing variable.

Students design an experiment to change the motion of a rolling marble. In this designing an experiment lesson plan, students form a research question, they develop a hypothesis and they design an experiment using a graphic organizer to...

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. 

In this experiment activity, students read over examples of different experiments and identify the control group, and independent and dependent variables. This activity has 20 short answer questions.

In this scientific methods worksheet, students identify the control group, independent variables, and dependent variables in 4 different experiment descriptions.

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...

Here is a handy handout to give any science class as a guide to writing lab reports. It is a blank outline that you can have aspiring scientists fill out when they experiment, or imitate as they record their experiments in a lab journal....

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.

Many variables impact your body mass, not just diet and exercise. Scholars collect and study data about body mass to better understand the complexity of a sensitive topic. They learn about leptin deficiency, the hypothalamus, and more.

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...
