Today we completed three sound experiments.  The first was Plucker UpStudents place a string in a cup (held in place with a paper clip).  They put their cup to their ear and pluck the string, listening to changes in pitch as the string got longer and shorter.
Next, they completed Party LineStudents made a “phone” and added other “phones” to their lines.
Students made a straw kazoo (Straw Sounds).
In the afternoon, students finished working on the review assignments.

Outer Space


Outer Space from Sander van den Berg on Vimeo.

The footage in this video is derived from image sequences from NASA's Cassini and Voyager missions. I downloaden a large amount of raw images to create the video. 
The song is The Cinematic Orchestra -That Home (Instrumental).

We finished our light unit with a refractions activity, It's Bent.  This was a two-part activity.  The question for the first part was:  Does the amount of water in a cup affect the refraction of light?  Students place ¼-cup, ½-cup, ¾-cup, and 1-cup of water in four different cups.  They placed a straw in each cup.  Based on their observations, they answer the questions.  The second question was:  Does the thickness of a liquid affect the refraction of light?  Students place water, vegetable oil, corn syrup, and shampoo in four cups.  They place a straw in each cup.  Based on their observations, they answer the questions.
Students completed the first sound lab - Tuning Fork Observations Students were given two different size tuning forks (one smaller, one larger).  They listen to the pitch and determine how the size of the tuning fork affects its pitch.  Then they hit one fork and place it on a desk.  Students place their ear on the desk and record what they hear. 
In the afternoon, we finished the Microbe Magic worksheet.

We finished the heat experiments doing The Marshmallow Roasts. The activity demonstrated heat transfer by radiation.  To complete the activity, students roasted and ate a marshmallow.
We began the light unit with Paddle ColorsStudents received six clear plastic color paddles (red, orange, yellow, green, blue, violet).  They combined different color paddles to see what color was produced.
We ended the day with Why is the Sky Blue?   Students put about twelve drops of milk in a clear jar of water.  They shined a light through it and saw a blue tinge. 
In the afternoon, we went into Computer Lab and used the Microbe Magic website to complete the Microbe Magic worksheet.

We completed two convection activities today.  The first was When Hot Meets Cold. Students filled up a container with tap water.  They filled up two baby food jars, one with hot water (colored red) and the other with cold water (colored blue).  They put on aluminum foil on top of the jars.  They were placed in the container on their sides.  Holes were poked in the foil.  They observed the water as it moved out of the jars.  They saw the hot water rising towards the top and the cold water falling towards the bottom.
The next activity was The Great Spiral. Students cut a spiral sheet of paper.  A piece of thread is taped on the spiral.  It’s held above a burning candle.  Eventually it will begin to spin because the hot air is rising.
In the afternoon, students watched Stars, Light Years, and the Milky Way and completed a worksheet. They continued working on the Phases and Constellations worksheets.

Tuesday, April 24th


Students completed two heat labs today.  The first was How Can You Have an Ice Cube Race?  Student measured the air temperature in one cup.  Using room temperature and hot water, students fill the second cup with water at the same temperature.  An ice cube is placed in each cup and they are observed until the first ice cube melts.  The purpose is to determine if water is a good insulator.
The other lab was The Great Spoon RaceStudents took a metal spoon, plastic spoon, and wooden craftstck and placed a penny on the handle using coconut oil shortening.  They are put into hot water and students identify which penny falls off first.  The purpose is to identify which is the best conductor of heat – metal, plastic, or wood.
In the afternoon students watched Observing the Night Sky and complete worksheetThey continued working on the Phases and Constellations worksheets.

Monday, April 23rd


We reviewed the principles of sound by watching Bill Nye Sound. 
We began our heat labs with Who's the Conductor?  Students take five containers made of aluminum, glass, plastic, Styrofoam, and plastic and place hot water in each container.  After about five minutes, they determined with objects were heat conductors.
In the afternoon, students finished Phases of the Moon worksheets and began working on Constellations worksheets.

Friday, April 20th


We began class by watching two Bill Nye videos reviewing the principles of light.  These were Bill Nye - Light and Color and Bill Nye - Light and Optics. 
After the videos, we began the sound lecture.
In the afternoon students watched Mythbusters.

Thursday, April 19th


Today, students completed the Yeast Beast lab activity.  They saw that the slice of banana had been decomposed by the yeast.  The slice of banana just placed in a bag didn’t look all that great, but the size of the slice was unchanged.
Students watched Bill Nye - Heat. 
We continued the heat, light, and sound lecture with a discussion of the principles of light.
In the afternoon, students finished their Seasons Review worksheets and began working on Phases of the Moon review worksheets.

4/18/12

Wednesday, April 18th


Student checked the status of their bananas today (Yeast Beast). 
Students examined their agar plates to see how effective spice was in preventing the growth of bacteria (Spice Up Your Life).  Most students found the spice inhibited the growth of bacteria.
We began the heat, light, and sound lecture.
In the afternoon, student worked on Seasons Review worksheets.

4/17/12

Tuesday, April 17th


Students checked their bananas (Yeast Beast).
We began a new experiment - Spice Up Your LifeStudents placed bacteria on an agar plate and were given a spice.  They covered half the plate with their spice to see if spice affects the growth of bacteria.
We watched Science Court – Living Things.
In the afternoon, students watched Bill Nye – Seasons and completed a worksheet while watching the video.  This was part of the seasons unit review.

Monday, April 16th


The rest of the classes completed the Bacterial Growth and Antibiotics assignment. 
Next, students checked their bananas to see how the yeast was affecting their banana (Yeast Beast).
Students completed the How Sugar Affects Yeast lab activity.  Students placed yeast and sugar in one cup and yeast only in the other.  They observed the cups for ten minutes and recorded their observations.
We will be taking the science core test in about a month.  We started reviewing the seasons unit.  Students watched Science Court – Seasons and completed a video worksheet.

Yesterday we began growing bacteria to see how specific antibiotics affected its growth.  Only 4th hour’s bacteria had grown to the point we could look at our results and analyze them.  2nd & 3rd hours samples were left in the incubator.  We’ll look at them on Monday.
All three classes began Yeast BeastThis lab activity investigates the effect of yeast on the decomposition of a slice of banana.  Students placed one small slice (2 cm thick) in a plastic bag.  A second piece was coated with ½-teaspoon of yeast.  They will be examined each day until Thursday. 
2nd and 3rd hours completed the How Sugar Affects Yeast lab.  Students placed yeast and sugar in one cup and yeast without sugar in another cup.  The observe growth for ten minutes and determine how sugar affects the growth of yeast.
