One of the most important parts of designing and conducting an experiment is to have an idea of how you will analyze and present your findings before you start. This way, you know exactly what data you will collect during your experiment.
The most useful graphs for science experiments are the Bar graph and the Line graph. Bar graphs are for comparing things, Line graphs are for following things that change. The following presentation is meant to help us better understand these graphs. You may do the whole presentation, but the first 30 slides are all that we will cover. Here is the packet we used as practice after the notes.
To start our new unit we were introduced to the core vocabulary and ideas in experimental design: hypothesis (we knew that one), Variable, Controlled Variable, Independent Variable, Dependent Variable, and the Control and Experimental Groups. We also practiced identifying these within experiments themselves. All of this was in the guided notes (here) (starting on page 2) that went along with these slides (starting on slide 16).
To help us better understand how scientists formulate and perform experiments, we’ll watch this video:
