First, we learned how to write hypothesis for an experimental design using the independent and dependent variables. We practiced using the variables from the previous class: variables_worksheet
Next we discussed the importance of control groups and repeated trials.
PowerPoint of note given is here: experimental-design-terms
Assigned homework is not available digitally, see me for a copy.
Blocks 3B and 4B also did an error analysis activity where the rotated through stations and identified various elements of experimental design (variables, control group, number of trials, wrote a hypothesis.)
