Science Community

When in undergraduate school, no one ever mentioned that being a teacher meant that you were going to be involved in so many communities. As a teacher you are a member of the community in your classroom, school, corporation, and community.

I must be forth coming and admit that I am not as large as a leader in any of these communities as I probably should be. I am a very busy with the tasks of being a mother of two young girls, a farmers wife, as well as completing the task of finishing a master's program. I understand that this are not good excuses.

The only way that I assist or lead my school or community is better understanding science is being my grade levels science chairmen. Holding this position requires me to attend text book adoption and PLC meetings. In these PLC meetings, we try to find ways to incorporate science into each grade levels curriculum. We also insure that each teacher has the science materials they need to successful teach their students the science curriculum.  

What’s Our Sputnik?

 

 

This article published by the New York Time in 2010 was very eye opening. I understand that the United States is needed around the world. However, I struggle to accept the thought of sending millions of dollars to foreign countries when there are children in our own country that are starving and being abused. Again, I understand that we can not ignore the September 11^th bombings or threats on our freedom, but why are we sending all of these countries millions of dollars when our economic outlook is so uncertain? As a country we should be focusing on building our country’s economic statue and keeping peace within our borders. I simply feel that we have enough issues on our home soil that we shouldn’t be helping others as much as we are. Our state and national government officials need to drive through some of our towns and visit the homes of those who really make America great. These individuals also need to realize that our students are this countries future. We must give them the tools to be competitive on a global level. Educating students in science and mathematics is an absolute must! Our students are our best potential investments.

Model Reflection

It amazes me how students of all ages love to make models. I had each of my students create a Tectonic Tennis Ball Model. My students loved this! As a whole, this class is very into science anyways, but this really excited them. Each child was able to create their own model which also added to the excitement, due to the fact that many times students work as a team during my science class. Each student was successful in making a model Earth; some needed more assistance than others. However, I did encounter the issue of completing this lesson in the allotted amount of time. I had only planned on this instructional plan taking two science periods. However, after being interrupted by a fire drill, I was forced to take three periods for this lesson. I found that the students were very interested in the topic and had many questions, which was nice! After completing this lesson, I must admit that I am very happy with the results. I feel that my students have a deep understanding of tectonic plates and their movements. I also feel that the students enjoyed themselves and had FUN learning.      

Natural Disasters

Depending on where you live, you are probably aware of a natural disaster that could happen any day. Living in "tornado alley" causes me as a teacher and mother to be very cautious of active weather. Earlier this year, we suffered a tornado out break in my area. Many people lost their homes, schools were destroyed, and many lives were lost. Only two weeks ago my school held students after school in our tornado areas because a tornado was on the ground only 3 miles from my school. It is so important to educate our students about all natural disasters. These things happen to innocent people every day. The more knowledge one holds the better they will handle themselves in a dangerous situation.

Ask a Scientist

Everyone has a question that they would love to know the answer to! It may be something simple about growing a plant or more complex like a plant's cell structure. I had the opportunity to ask a scientist my burning question. Here is what I asked:

My question is about Somatic cell nuclear transfer (SCNT). This involves transplanting a patients genetic material from something as simple as a skin cell into an unfertilized egg in order to grow the patient specific stem cells. No sperm is involved, and therefore no fertilization occurs, in this procedure. Also, with this process the egg is not placed in a uterus so there is no fetus or fertilized egg. My question is when will these cells be used in the treatment of diseases and other medical issues? Also do you think these cells will encounter the ethical issues that embryonic cells face?

Any many people know, stem cell research is a hot topic in today's news and politics. I am curious about this type of stem cell research due to the fact that it could benefit so many people who suffer from health issues.

I have not had any feedback from a scientist yet, but will update my blog as soon as I do. :)

Presentation Tools

Everyone needs an exceptional presentation tool in their tool kit. When checking out some presentation tools this week, I have found two that I think are really great. PreZentit is a presentation tools that is simple to use and the best part is.... if you are working on a presentation with team members you can all use this tool at the same time! That's right, you and your partner can be working on your presentation at the same time without being in the same room. I also liked Prezi due to the fact that it seems simple to me. I like the information zebra tool due to the fact that you can do so many things through the one tool. I also like the bubble menus being in the corner. I am thinking that I am going to use the Prezi for my course project. However, if you are completing your project with a partner, definitely check out the PreZentit.

Heating Things Up!

During week 4 of Physical Science, we have been learning about the three types of heat transfer and experiment with different types of insulators. During this experiment, I used aluminum foil, bubble wrap, a cotton dish towel, and a Sparkle paper towel. Using water that was brought to 80 degrees Celsius, I filled my four cups to the same level. I covered each cup with an insulator and used a rubber band to ensure that the insulator was covering the opening of the cup tightly. After thirty minutes, I uncover each cup and used a simple thermometer to measure each cup of water's temperature. In conclusion, I discovered that the foil insulated the water the best. The bubble wrap can in second and then the dish towel. The Sparkle paper towel lost the most heat.
If I had to complete this experiment again I would use more non-traditional materials such as, a wool scrubbing pad, press n seal wrap, a large piece of bandage and possibly a piece of flat glass. I think that using more non-traditional materials would make this experiment more interesting. When think about how I could complete this experiment in my second grade classroom, I am a little stumped. My students do not learn about the different types of heat until they are in third grade. In second grade, students are to know and understand that substances stay hotter longer if they are in smaller containers and that if you would like to cool a substance down, blowing on it or placing it in a larger container would be correct. Instead of determining what materials are better insulators, I would have my students measure the temperature of oatmeal that is in different size containers. I know that our third grade science teachers complete the insulator experiment near Thanksgiving. I understand that my experiment would not achieve the same results, but it would fit my curriculum and standards much better.
