Comparison of both Observations

First observations focused on observable  physical properties, passively. Observations were both quantitative and qualitative.

Second observation focused on the results of various experiments with candles, observations of change. Once again, the observations were both quantitative and qualitative.

Why did we do the bean project?

The project helped us to think about the way things interact (physics). Instinctively following the Harwood Model, we engaged with the challenge in many ways, alternating between modes of inquiry, deepening and broadening our understanding each time. We thought about the task, performed tests, and talked with each other about what could be happening.
We did all of this to explore, experiment with and increase our concrete understanding of the natural forces of physics. By going through the steps, with projects of our own design and of others', we manipulated the forces, velocity, friction, and gravity. We were given limited tools and precise objectives. Each of us had to actively engage our imagination to conceive of the designs, and in the end, to succeed in our task.

We started out with Anita, Brittany and Adriana. Later Mckennzee and Jessica joined us!

Harwood Model vs. Baloney Detection Kit

The Harwood Model is useful to show the many steps that you can take at any point during and investigation or an experiment. There's not really any beginning or end, just more questions. In comparison, the Baloney Detection Kit urges us to be totally skeptical of any claim, scientific or otherwise, and provides some steps for evaluating claims.
The Harwood model does not question any claims validity, it provides direction for further investigation. The Baloney Detection Kit was designed to disprove 'bogus' claims. I think that both are useful, though I feel more affinity for the intuitive nature of the Harwood model, I think that applying a little more skepticism would be highly useful for me.
In this class, so far, we have focused on the Harwood model. Although, I do see that we applied the Baloney Detection Kit when we traded notebooks, teasing out the problems, and then trading again and looking at each other's conclusions.
