Urbas - Science Week of March 25 - April 4

A summary:

Students have just finished a quiz on material covered in our Light unit.

Spring break is here and many students are going to various places around the country.

Now if Spring would just arrive here!

When school returns next month, students will continue to investigate Light and Color, and will be working with colors and pigments. Stay tuned.



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.

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."

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 March 4 - 10

Students are beginning their investigations of Light and Color this week. We have just finished our yearly ISAT tests, the kids are happy, and now we are in the third trimester of the school year. In the next few weeks we will be working with lenses, prisms, mirrors and color mixing using pigments and plastics. Stay tuned.
