Urbas - Science Week of August 26 - September 1

Welcome to 6th Grade

Mr. Urbas

Science 6th Grade



I would like to welcome all of the new students to Lakeview Junior High whether you come from Prairieview or another school. Your next years will be filled with new challenges, opportunities, and possibilities.


I teach science in the sixth grade and have been doing so at Lakeview for the past 17 years. In addition to teaching, I also coach Cross Country, a sport I encourage you as a sixth grader to participate in during the fall. I also coordinate a Science Club in the spring which is open to all students in which we perform various experiments that are not a part of the science curriculum at Lakeview.



The science curriculum in sixth grade is one based on the studies of Earth and Physical Science. The class has an emphasis on hands on activities and the lab is a major part of the curriculum. Students are expected to participate and act in a safe manner whenever working in the lab setting. Units of study include metrics, safety, machines, geology, plate tectonics, color and light, astronomy, and topography.

The curriculum is matched to state standards and is designed for the student to be successful during the process. Required work consists of daily work, pre-labs, lab assessments and quizzes and tests. To be successful a student needs to complete the work in a timely manner. Specific rules and procedures will be given out to each individual student in the fall at the start of the year to be reviewed by the student and parents both.


I can be reached by accessing my e mail at:


murbas@ccsd66.org

or

(630) 783-5035


Please feel free to contact me and I hope to see you at the Parent Open house sponsored at Lakeview.

New information is that Science Club has started for the Spring and if you are interested, stop by and see Mr. Urbas for an application.

















Students pictured are working on determining their "Blind Spots" in their vision.

Friday, March 18, 2011

Urbas - Science Week of March 18 - 24

This week students have continued their search for the speed of light and reflections. They calculated the distance light travels in a year and determined how far the star Alpha Centauri is from the Earth.

In the pictures below, students are working to prove that the angle of incidence is equal to the angle of reflection. They are using a light and a protractor to measure the angles.





"I think you have an angle for this."

Friday, March 11, 2011

Urbas - Science Week of March 11 - 17





Students this week have been investigating light and its effects. The visual you see on the right is an illusion showing how our eyes can trick the mind.





Students below are experimenting with the path a beam of light follows. They observed that light always travels in a straight line unless that beam is reflected, refracted, or obstructed.
We will be continuing with color and light investigations this upcoming week.

Urbas - Science Week of Feb. 18 - 25


Students this week tested the strength of their Tower constructions against Mr. Urbas's Epicenter Earthquake Machine. The students worked for approximately a week on their constructions, sharing ideas and strategies with their teamates. When the final day came, they were ready.


Although several of the Towers were able to withstand a Richter Scale rating of 7, not one was able to withstand the total 9 the machine can generate. This is the first time the machine actually won the battle against all contestants. At the end, most students wanted another shot at beating the Epicenter Machine. Some pictures are below.








Typical Tower with plates on three levels to simulate the load of a building.











This Tower was leaning a little bit before the start of the earthquake.












The remains of what once was a three story Tower at a Richter Scale reading of 7.









Friday, February 11, 2011

Urbas - Science Week of Feb. 11 - 17

This week in class, students put their finishing touches on their Tower constructions. Below are picture three of the groups that have made great progress in the process. On Monday, the Towers will be subjected to earthquake stresses up to a level of nine on the Richter Scale. Next week there should be some great pictures of the experiment. Stay tuned!








"All three levels are where they should be".













"Colorful and simple".











"I don't think everything is on the level"!










Friday, February 4, 2011

Urbas - Science Week of Feb. 4 - 10

Students have been busy this week building their Towers in class. That is until Wednesday, Groundhog's day, when we received a small amount of snow. Due to this minor problem, the Towers will not be due until Wednesday of next week. Below are some pictures of happy groups.






Three platforms done!














One level down, two to go!












Happiness is an almost complete Tower!

Urbas - Science Week of Jan 28 - Feb 3

Students this week in Science have been working as Seismologists in order to determine the epicenter of an earthquake in the U.S. Pictured below are two groups who are using using triangulation to find the spot an earthquake occurred from seismic wave data.

This week they are working in groups to try to assemble a structure to withstand Mr. Urbas's famous Earthquake machine. Pictures of that project will be in the upcoming weeks. Stay tuned.





Student predictions of where did that earthquake start?











It has got to be in this area!

Friday, January 21, 2011

Urbas - Science Week of Jan 21 - 27



Students continue to investigate the Earth and the concepts associated with it.

Next week they will start on how to determine exactly where an earthquake occurs just like an actual seismologist does. The process is done using triangulation based on information received at a recording station. Keep tuned in.

Friday, January 14, 2011

Urbas - Science Week of Jan. 14 - 20.

Students this week have been trying to reconstruct the original continent of Pangaea, "one land". By using clues based on scientific observation, students should be able to reassemble the continent.
This upcoming week, they will be learning about faults, what causes them and the results of movement. Whose fault is it anyway?

Friday, January 7, 2011

Urbas - Science Week of Jan. 7 - 13



Students are back from the Christmas break and have started investigating the Earth in relation to it's layers and Plate Tectonics this week. Included are pictures from the suggestion of Mrs. Maass in Social Studies that show "Arnold" in a "Pangaea, the SUPERCONTINENT" pose. SS and Sci have been collaborating on the study of Pangaea recently and the kids really enjoyed the connection. The students are also doing their best "Arnold" pose.



Arnold looks ready to hold up the continent.

Parents, the new set of notes from the unit on Plate Tectonics and Earthquakes has been posted on my blog.
