Designing Experiments - Procedures for Teachers
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 experiment...
Curated OER
Ketchup Lab
In this ketchup activity, students investigate the thickness of different types of ketchup. They hypothesize, identify their independent and dependent variables, test their hypothesis and write conclusions based on their data.
Curated OER
Looking At Variables
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...
Curated OER
Experimental Design Reference
In this experimental design worksheet, high schoolers are given a full comprehensive outline for designing an experiment. There are checklists included for each section of the experiment for students to use as a guide for properly...
Curated OER
Practice Evaluating Experimental Designs
In this experimental design worksheet, students evaluate experiments using a design checklist. They suggest ways to improve the experiments and they identify all the components of the design.
Curated OER
Germination Inhibitors
In germination experiment worksheet, students conduct the following lab activity. Students determine the effects of another tomato on germinating seeds. Students answer the following questions to analyze their experiment.
Curated OER
How Much Sugar is in Bubble Gum?
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...
Curated OER
Freshman Project-Part Two-Experimental Design
In this experimental design activity, students identify the title, hypothesis, independent and dependent variables , the constants and the control for their experiment. They use a scoring guide to asses their progress.
Curated OER
Scientific Method
In this Scientific Method worksheet, students identify controls and variables given hypothetical situations taking place in Bikini Bottom. Students draw conclusions form the information they gathered in the experiments.
Curated OER
Hydraulics and Pneumatics
Seventh graders participate in an experiment using syringes. In this physics lesson students demonstrate the movement and principles of pneumatics and hydraulics.
Curated OER
The New Wind Turbine
Students study the basic components of a modern wind machine. In this investigative lesson students investigate and find out if there are any wind machines in their state, how many and how much power they produce.
Curated OER
THE ROLE OF A CONTROL IN THE EXPERIMENTAL DESIGN
Students study the role of controls. They discuss variables and list conditions, that if not kept the same for both flasks, could effect the outcome of the experiment. They come up with most of the following: Amount and temperature of...
Vision Learning
Visionlearning: Research Methods: Experimentation in Scientific Research
An explanation of scientific research using variables and controls.
TeachEngineering
Teach Engineering: Wet Pennies
Students conduct a simple test to determine how many drops of each of three liquids can be placed on a penny before spilling over. The three liquids are water, rubbing alcohol, and vegetable oil; because of their different surface...
