Friday, April 29th

Students watched Using Light and completed worksheet.
Student completed two light labs - The Amazing Reappearing Penny. Students placed a penny in a bowl, moved to a position where they couldn’t see it. Water was slowly poured into the bowl. Through refraction, students saw the penny “reappear.” The second light lab was It's Bent I. Students placed differing amounts of water in cups. A straw was placed in each cup. Students were to determine if the amount of water affected refraction.

We will be taking the light unit assessment on Wednesday, May 4th. Students received the light review booklet and light study guide.
Students completed two light labs. The first was The Zig-Zag of Reflectors. Students were given five mirrors. They were to set them up and bounce a laser pointer off the mirrors and hit a 3x5 card held by a group member.
The second was - How Does Primary Colored Light Affect What You See? Students shined a white, blue, red, and green light on a sheet of white, blue, red, and green paper. They recorded what they saw.


Wednesday, April 27th

Students took a light quiz today.  After the quiz they read sections of the light text and completed a worksheet.


Tuesday, April 26th

Students completed a light and color activity - Decoding Secret Messages. Students were given five “color-by-number” pictures.  After they were colored, they used different color filters to identify words or pictures in each picture.


Friday, April 22nd

Students completed a heat transfer quiz. They also completed two light labs.
The first was It's a Reflection. The purpose of the lab was to demonstrate the law of reflection.  It states the angle of incidence = the angle of reflection.  Students shined a laser pointer at a mirror from different angles to verify the angles are the same.  They also examined how the angle of two mirrors affects the number of images in the mirrors.  (The larger the angle, the more images.) 

The second was Reflective Surfaces. Students shined light off of different surfaces to see how smooth or rough a surface is affects reflection.  They found the rougher the surface, the less reflection.


First No-Hitter Pitched Tonight

Cubs pitcher Jake Arrieta pitched the first no-hitter of the season and his second career no-hitter against the Cincinnati Reds.  Cubs won 16-0.

Congratulations to Jake Arrieta for an outstanding performance!

Wednesday, April 20th & Thursday, April 21st.

Wednesday, April 20th
Students watched Bill Nye - Light & Color & Light & Optics and completed a worksheet.
Thursday, April 21st

Students completed two light labs. The first was Adding Color. Students combined flashlight with red light, blue light, and green light to learn red, green, and blue light make white. The second was Why is the Sky Blue?  Students shined a flashlight into a jar with milky water.  It demonstrated how light is reflected by particles in the atmosphere by light being bounced of particles in the milky water.


Monday, April 18th

Students completed two convection labs.  The first was When Hot Meets Cold. Students filled two baby food jars with hot water colored red and cold water colored blue. The jars were covered with aluminum foil and placed in a container of tap water.  A hole was punched in the foil.  They were to observe the hot water rise and the cold water fall to the bottom.
The second lab was Water Wars. Students place clear hot water in a test tube and clear cold water in another test tube.  They dribbled hot water colored red in the cold water test tube and cold water colored blue in the warm water.  They were to observe the hot water in the cold water rose to the top.  The cold water colored blue in the hot water fell to the bottom of the test tube.

Today we began the principles of light unit with the light lecture and notes.

Students will take the heat unit assessment on Monday, April 25th. Students received the Heat Review Booklet and Heat Study Guide.


Friday, April 15th

In preparing for the upcoming SAGE test, students took a science review assessment. This covered the units studied before the microorganisms unit.  I will be using results from the assessment to plan review lessons.
After, students watched MythBusters – Mega Movie Myths.


Thursday, April 14th

Students completed a conduction lab - Conduction With Water Balloon and Candle. In this lab, students placed a balloon filled with air in a flame.  It pops because air is a bad conductor of heat. They place a water balloon in a flame. Nothing happens because water conducts the heat away from the balloon before it can burst.
They also completed a heat transfer lab - Where is the Heat Going? A bag with hot water was placed in ice water.  This demonstrated heat moves from hot to cold.


Wednesday, April 13th

Students completed two heat labs today.  The first was a conduction lab – Butter on a Wire. Students had three different wires – brass, copper, and stainless steel.  They placed butter about 1/3 of the way down the wire and placed the end of the wire in a candle flame.  They were to determine which metal rod best conducted heat.
The second lab was an insulation/conductor lab - Ice Cube Race.  Students placed an ice cube in a cup full of room temperature water and one in an empty cup.  Their assignment was to identify which was an insulator or a conductor.


Tuesday, April 12th

Students watched Bill Nye - Heat and completed a DVD worksheet.
Students completed a conduction lab - Who's the Conductor?  They filled a plastic cup, paper cup, Styrofoam cup, empty metal soup can, and a glass glass half-full of very warm water.  After ten minutes, they touched each container and determined which were good and bad conductors.
