DNA and regulating genes. Homework, view the following video and provide me with a statement regarding its content.

TAKS Objective 1

Scientific Method

While there is no one way to study science, a generalized method for conducting science has the following elements:

Observation - If you are going to study nature, you must first see what nature does.

Generating a model and testable hypothesis - The model is an initial set of statement that detail how you think the system operates, based on your observation. The hypothesis is a prediction from your model that you can test in some type of controlled environment.

Experimentation - The test of the model occurs in experiments in which you can control certain variables to see how nature responds.

Creation of a theory (based on data) - After the testing phase, you are now ready to make a stronger statement about how the system operates. Your experiments might also allow you to quantify certain aspects of your model.

Application of the theory (conclusion) - Your theory should now allow you to make more predictions about the system. These new hypotheses can be tested with other experiments.

Go to the following link http://classroom.springisd.org/webs/nancyn/science_taks_information.htm
Open the TAKS Objective 1 tab, review the powerpoint presentation.

Design an experiment based on the scientific method. We have done this in class but you can just list the steps and explain each step with 2-3 sentences. Save your file (or your flash drive) or you can e-mail it to me at myscienceclass@yahoo.com.

May 1-8

FWISD schools are closed until May 11, 2009. Tune in Channel 30 or go to www.fwisd.org for updates for school closings and Health Department concerns on the swine flu.

In the meantime, I know you all are missing me and want to continue your learning. Learning continues without our presence so those of you who are home and have internet access, go to the following link, follow the instructions to set up the account and take a practice TAKS exam. Currently, there are no exemptions for learning....so get to it!

http://www.track.uttelecampus.org/started.aspx

I will continue to post assignments this week. Save it to your hard drive and bring it to school when you return and I will give you credit for the work.

Stay safe and healthy.
