Curated OER
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...
Curated OER
Identifying Variables
In this variables learning exercise, high schoolers 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 learning exercise, students 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.
Curated OER
A Constructivist Version of the Snail & Elodea Lab
Students explain the importance of having a control when setting up an experiment.
Curated OER
