Choosing a Study Design for the Polio Vaccine
Be on the right side of history. Scholars first learn about polio and the meetings of the 1954 Salk polio vaccine study. In groups, they select roles, such as parents, government officials, and statisticians, and decide on the best...
Flipped Math
Experimental Design
Experimentally, come up with a study design. Learners hear about different types of study designs, observational studies, and experiments. They identify the subjects, response variable, treatment, and whether there was a cause and...

Controlling Water Activity in Food
Food storage matters! Scholars learn how the amount of water in corn can affect its rate of spoilage. They create a control group, then test three corn samples stored in three different locations for water activity. As a result of the...

Scientific Inquiry: Measurement/Data
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.
Curated OER
The Marvels of Mud
Young scientists roll up their sleeves and get a little dirty in this three-day earth science investigation. Following the scientific method, children monitor the growth of algae in pond water samples in order to determine the role that...

Generating Hypotheses and Experimental Design 1
Here is a thorough exercise in forming hypotheses for scientific investigations. Young scientists consider factors that may be related to the question they would like to address. They think through measurable changes that may result from...

Identifying Variables
In this variables instructional activity, students are given seven experiments that they read and identify the independent variable, dependent variable, control group and standardizing variable.
Curated OER
Controls and Variables
In this scientific methods worksheet, learners identify the control group, independent variables, and dependent variables in 4 different experiment descriptions.
Curated OER
Identify the Controls and Variables
In this experiment worksheet, students read over examples of different experiments and identify the control group, and independent and dependent variables. This worksheet has 20 short answer questions.
