Today’s focus was around refining students’ understanding that controlled experiments, where just one variable is changed at a time, yield the most informative and reliable results. In most experiments, there are many variables that exist and that can play a role in the outcome of an experiment, but controlled experiments show us the most clear relationships between the manipulated (independent) and responding (dependent) variables. For example, students were asked to consider the types of variables that could affect the growth of a bean sprout and the amount of fish in the water. GREAT answers! This lesson was intended to scoffed upcoming small group experiments where students will be controlling one variable to measure its effect. Students were told today that there will be a Variables Quiz either Tuesday or Wednesday. (I will be assessing their readiness this Monday during in class exercises!)
