Sand Bag and Motion Man Activity

The Moving Man of Science

--- For this activity we recorded position, time, instantaneous and average velocity, acceleration, and inertia.
The graphs on top represent a change in distance over time which is equal to a constant velocity.  V=x/t
The graphs on the bottom row represent the change in velocity over change in time- which is acceleration.

For the following graphs we plotted all of our data and calculated the slopes for each trial.

Newton's Laws of Motion

First Law of Motion: 

An object at rest or an object moving at a constant velocity will remain constant unless acted upon by an outside force.

(Insert Picture of Box of Joy and Earth) 

 

Second Law of Motion:

Force = Mass x Acceleration

Third Law of Motion: 

Every action has an equal and opposite reaction. 

Energy:
 We learned that energy is conserved as kinetic and potential energy and are inversely proportional: as one increases, the other decreases.

SBG Sheet

We used Strand 1 in the classroom when deciding on what project we were each going to come up with- involving candles. We all had previous general knowledge about the uses of candles so we built ideas branching from there.

Strand 2 was met when our group made a hypothesis about how we thought our wick would burn faster if we increased the amount of wax we took away from the candle. We took our previous knowledge and applied it here.

We met Strand 3 because before beginning a completely new assignment, our Professor (Matt) helps us reflect on what certain ideas and concepts really mean to us. After collecting data involving the sand filled balloons, we were able to come up with explanations as to why or why not it wasn't very accurate.

Strand 4: As far as participating in scientific debates goes, we have not exactly addressed that stuff yet. However, we are all usually willing to ask questions when we need to.

Questioning process

It was amazing to see how so much came from that one activity. It was a little difficult to get started with questions, but once we got going it then became much easier. I always knew science was important, but we all subconsciously use some form of science every day- and that's what I did not realize. I really enjoyed the questioning activity and I think it can be useful for many different things and can also help us learn more in several ways.

Homework 1

1.) Science is a "tool" we use in order to explore things in depth. It's also a way to discover and develop new ideas.
2.) While in high school I participated in a program that pertained to alot of environmental science kind of work. It was a great experience because if I hadn't gotten the opportunity to go out and collect data in the forest, and learn about how important it is to protect our environment- I would've never realized that environmental science is what I wanted to major in, nor would I have truly understood how important. It was a very fun experience and I really enjoyed the hands on work that was involved. I've never liked doing science projects and that has honestly been the worst science experience I have had. I was never really interested or into any of it, but it could be because I was possibly not doing the right science project for me.
3.) While cooking I form a hypothesis about how long each food item is going to take, in order to try to have my entire meal complete at the same time. While doing so, I observe the food every now and then to be sure that I have cooked everything perfectly. Therefore I think it's fair to say that the scientific method is used throughout this whole process.

Natural Science

 I am currently taking Natural Science 261 because it was a requirement for me and it seemed pretty interesting to me. I hope to learn as much as possible and hopefully finish this class with a good grade.
