Hi All,
Another great day. We are all getting the picture of how mathematics can be understood very well as we apply them to science concepts and experiments.
For tonight, please blog about not only your impressions but answer the discussion questions and put the concepts in your own words from the questions at the end of the handout on circuits here.
...making bulbs brighter than the others.
Hint: The current will split proportionally to its resistance, meaning that in a parallel branch with two series resistors in one branch and a single resistor in an other branch (like combination circuit 3)twice as much current will flow t through the branch with the single resistor. since it has one-half of the resistance as the other branch which receives one third of the current.
Also, Dr. Koppang would like you to answer his questions on the handout of this afternoon's lab. Also, discuss the graphing process that you did today.
Have a restful evening and we will see you in the am.

Day 3
ReplyDeleteCircuits Lab
When working with a series circuit, the bulbs will be of equal brightness. Adding more bulbs to the dry cell the brightness will decrease for all bulbs. When working with a parallel circuit, the bulbs will be of equal brightness, regardless of how many are connected to the dry cell.
Enzyme Lab
The graph that needed altering was the intensity vs. proton concentration. By using the natural log OR log it would represent our data better. In an enzymatic reaction, enzymes have a higher level of reactions (create a more intense color) when more substrate is present.
Thoughts/Comments
I am struggling with all of the equations and the high level of mathematical understanding that is expected with this course. There are many times that I am not clear on what is being discussed or presented. Many of these activities are rich learning experiences. My problem is that I teach such a basic form of science, that these activities are not going to be applied in my classroom, beyond my own personal knowledge. (for example: for enzymes I teach what an enzyme is (speeds up a reaction without being use up) and where it can be found in the body).
