We continued doing sound lab activities.
  • King Gong – Students make headphones using two cups and string.  They place a hangar on the string.  They tap it against objects and listen to the sound it makes. 
  •  Party Line – This is the “telephone” activity.  Students start with two cups and a string.  They add phones on to the line until all group members can participate in the conversation. 
  • Plucker Up – Using a cup with a piece of string, students pluck the string and listen to the sound.  They make the string longer and listen to the change in pitch.

Both classes completed two sound lab activities. 
  • Tuning Fork ObservationsStudents are given two tuning forks (different frequencies).  They compare the pitch of the two tuning forks, identifying which has the highest and lowest pitch.  Next, students tap the tuning fork and place the handle on a desk.  They put their ear on the desk and listen to the tuning fork.  The last activity is to tap the tuning fork and place it in water.  This helps demonstrate sound and vibration.
  • Making a Bee Humme(for more information, click here) – Students make a bee hummer using a craft stick, two erasers, a 3x5 card, and a rubber band.  When assembled, they swing it over their head.  The rubber band vibrates and makes a sound like a bee.

Student completed two convection activities.
  • When Hot Meets Cold – Students place two jars in a container of tap water.  One container is filled with hot water with red food coloring; the other is filled with cold water with blue food coloring.  The jars are covered with aluminum foil and placed in the container.  Holes are made in the foil and students observe the movement of the water (hot rose to the top; cold dropped to the bottom).  
  • Water WarsTwo test tubes are half-filled, one with hot water and one with cold.  Red-colored hot water is drizzled into the test tube with cold water.  Blue-colored cold water is placed in the test tube with hot water.  Students observe the movement of the water (the cold-water drops to the bottom of the test tube filled with hot water; the hot water rises to the top of the test tube filled with cold water.

Honors Science – The two groups made their formal project presentation to the Mars Student Imaging Project team.  They did an outstanding job with their presentations and will now request photographs of Mars.

We began class by watching a light video.  Students completed a worksheet while watching the video.  Students completed the following light labs: 
  • How Does Primary-Colored Light Affect What You See?  - Students shine a red, a green, and a blue filtered light on white, red, green, and blue paper.  They record their observations.
  • Exploring Why the Sky is BlueStudents shine a white light through a jar that contains milky water.  The milk in the water scatters the light and gives the jar a bluish tinge. 
  • Adding ColorsStudents shine combinations of red, green, and blue lights and observe the colors they make.

Honor's Science – Students watched Good Eats - Yogurt - Good Milk Gone Bad and completed a worksheet. The worked on the following assignments:

Students worked on a meteor review activity, Meteoroid, Meteor, Meteorite worksheet
They started a light and color lab - Decoding Secret MessagesStudents color five pictures based on a color key.  When finished, they will use a red and green filter to determine the message.
Honor's Science - Worked on Mars project.

Tuesday, April 16th


Students completed a light (refraction) lab - It's BentIt was a two-part lab.  In Part I, students explored the question, Does the amount of water affect refraction?  They filled four cups with differing amounts of water (1/4, ½, ¾, and one-cup).  Straws were placed in the water and students observed the straws.  For Part II, they explored the question, Does the thickness of a fluid affect refraction?  They had a cup with water, one with cooking oil, one with corn syrup, and one with shampoo.  Straws were placed in the water and students observed the straws to determine refraction.
Honor's Science – students worked on a series of microorganisms worksheets.

Monday, April 15th


Students watched Bill Nye - Light & Optics and completed a video worksheet.
They completed a light activity - The Zig-Zag Race of Reflectors.  Student lined up facing each other and held a mirror (three or four mirrors, depending on the size of the group).  The challenge was to bounce the light off each mirror.
Honor's Science – Students worked on their Mars project.

Today was our last day of remediation for the microorganisms unit (microorganisms remediation assignments).  Tomorrow we will re-take the test.
Honor's Science – Students watched Science Court - Living Things, Microscopic Life, and Protists videos and completed worksheets.

We began the review for the microorganisms re-test.  Students are assigned assignments based on which part of the test they need to retake.  Assignments can be found here - microorganisms remediation.
