Students completed a microorganisms lab - How Does Sugar Affect Yeast?  Students compared the growth of yeast, one sample with sugar and yeast; the other with yeast alone.  The yeast with sugar grew best because yeast only had no food.
Honor's Science – Students finished the Kids Discover Microbes magazine assignment.

Students finished presenting their Disease Wanted Poster presentations. 
They completed two worksheets. 
Perils at the Picnic – Students read about a picnic after a baseball game, identifying what those involved did wrong. 
What's My Diagnosis? – Students are given a set of symptoms.  Using a classification key, they identify the diseases.
Honor's Science - Worked on Mars project.

Monday, March 25th


Students were assigned a disease caused by microorganisms.  They made a Disease Wanted Poster.  After finishing the poster, they presented information about their assigned disease to the class.
Honor's Science – We began the microorganisms unit.  Students completed a microorganisms introduction assignment - What is a Living Thing?  After completing the assignment, student began reading Kids Discover Microbes magazine and started working on a worksheet.

We began a microorganisms lab, How Antibiotics Affect BacteriaStudents take a bacterial sample and placed four antibiotic sensitivity discs (one penicillin, neomycin, erythromycin, and ampicillin) on bacteria in each plate.  They will be checked tomorrow.
Honors Science – Students watched Science Court - Seasons and Bill Nye - Seasons and completed worksheet.

Wednesday, March 20th


Students completed the microbe worksheets. (Information to complete worksheets).   The next assignment is for students to read Kids Discover Microbes and complete worksheet.
Honor's Science – Students completed the SHARP Youth Prevention Needs Assessment sponsored by the Utah Department of Human Services.

Students analyzed their Spice of Life  agar plates.  The combined results are show below.


*2nd hour oregano group put very little spice on their plate.  This affected their results, so it was thrown out.

Effectiveness Key

1 – Ineffective
2 – Somewhat effective
3 – Effective
4 – Very effective

The spices most effective at preventing bacterial growth were oregano, clove, and cinnamon.  The least effective were onion powder, allspice, and ground mustard.
Student continued working on the microbe worksheets. (Information to complete worksheets)
Honor's Science – Students completed the following seasons labs:
The Shadow Knows – Students measure the length of a straw’s shadow at four different angles.   The purpose is to show the smaller the angle, the longer the shadow and the more indirect heat energy from the Sun.  The larger the angle, the more direct heat energy from the Sun.
Sun Above the Horizon – Students shined light on graph paper shined at three different angles representing summer, winter, fall, and autumn. 
Tracking the Movement of Shadows Over Time – Students put a straw vertically outside and measured the angle of the shadow over 30 minutes.

Today, we did a microorganisms lab.  We are investigating how spices affect the growth of bacteria (The Spice of Life).  Students put bacteria on a nutrient agar plate and covered ½ of the dish with spices.

They were placed in an incubator to give the bacteria time to grow.
Students began working on a series of microbe worksheets.
Honor's Science – Using the comments they received on Friday, the two groups continued working on the Mars project.

Students worked on a computer assignment.  They went to the website the Microbe Zoo .  While going through the website, they completed a worksheet.
Honor's Science – Worked on the groups’ Mars proposal presentation.

Tuesday, March 12th


Students who needed to re-take or make-up the scientific method test had the chance to do it today.
Students worked on making four posters:
  • Ways we get diseases.
  • How to cook and store food properly.
  • How to wash your hands.
  • A poster explaining when you should was your hands.
Honors Science – Students continued working on their Mars proposal presentation.

Students watched the Discovery Channel video Understanding Bacteria.  The video explains bacteria.  They also explain harmful things bacteria do.  Benefits are also discussed.  Bacteria’s role in making sourdough bread is discussed. 
The most exciting use of bacteria was in the Homestake Gold Mine in South Dakota.  They had been polluting a stream so bad nothing could live in it.  The water in it was black.  They were told by the EPA to clean up the stream and the CEO of Homestake said he wanted the stream so clean trout could live in it again.  They successfully cleaned the river by using bacteria that eat cyanide (used in separating the gold from the ore). 
Honor’s Science – Students a preparing their Mars proposals on Friday.

Comet PANSTARRS Visible




Comet PANSTARRS is  visible in the Northern Hemisphere!  A NASA news release says, in part: 
By March 8, comet PANSTARRS may be viewable for those with a totally unobstructed view of the western horizon for about 15 minutes after twilight. On March 10, it will make its closest approach to the sun about 28 million miles (45 million kilometers) away. As it continues its nightly trek across the sky, the comet may get lost in the sun's glare but should return and be visible to the naked eye by March 12. As time marches on in the month of March, the comet will begin to fade away slowly, becoming difficult to view (even with binoculars or small telescopes) by month's end. The comet will appear as a bright point of light with its diffuse tail pointing nearly straight up from the horizon like an exclamation point.

We finished the intro to microorganisms lecture and notes. Students next took a quiz on the information presented in the lecture.  Student then began working on a reading about what constitutes life and began working on a worksheet.
Honor's Science – Students will make their proposal presentations next Friday.  They are continuing to work on their Mars proposals.

We began the microorganisms lecture today.  We got as far as almost completing the bacteria section.  Students completed a worksheet during the lecture.
Honor's Science – Because we had good weather today, students completed the seasons lab - Why is Summer Hot?   Students placed two thermometers outside, on in direct sunlight and one in indirect sunlight.  The thermometer in direct sunlight had a higher temperature than the thermometer in indirect sunlight.  Students worked on their Mars proposals.
