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...

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...

An inquiry-based algebra lesson explores real-world applications of linear functions. Scholars investigate four different situations that can be modeled by linear functions, identifying the rate of change, as well as the...

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...

Scholars find a pattern from a geometric sequence and write the formula for extending it. The instructional activity includes a table to complete plus four analysis questions. It concludes with instructional implications for the teacher.

Students analyze different experiments to determine independent variables, dependent variables and control groups.

Given investigation scenarios and lab procedures, students will identify independent variables, dependent variables, constants, and control groups.

Students identify and control variables to design an experiment to see whether the temperature of a solvent affects the speed at which a solute dissolves.

Lesson plan with mulitmedia links in which students identify and control variables to help design a solubility test for different liquids in water.

Students are challenged to design a way to drop a raw egg from varying heights without letting the egg break. Creative thinking and evaluation of results are critical to the project.
