Students completed the Bacterial Lab - Bacterial Growth and Antibiotics. They
did a Sound Activity - Animal Challenge. Students heard six animals and
had to determine if the animal was large or small and was their pitch high or
low. They continued working on Science ABC Book (references).
One of the honor’s student’s father, Mr. Aaron Matheson, was
our guest speaker. He talked about ATK's
role in the new Space Launch System.
Students began a microorganisms lab – Bacterial Growth and Antibiotics.
Students placed bacteria on an agar plate.
They were give four small discs – three were three different
anti-biotics and one was a plain paper disc.
They placed the discs on the bacteria.
Tomorrow they will check to see
if they have any results.
Microscope activity. Students were given seven different slides of
microorganisms. They drew what they saw
in the microscopes and wrote a description.
During the microorganisms unit, we did not have enough time
to do a couple of labs. One was The
Spice of Life. We did this today. Students were given an agar plate
with bacteria. Half of the plate was covered with spice. The purpose is to
determine which spices affect bacteria.
Students completed two sound labs - Straw Sounds and Sound Sandwich (click here for
Students made a “kazoo” out of a straw. This demonstrated
sound and vibrations. Next, they blew on their straw “kazoo” and cut off part
of the straw. This demonstrated pitch – as the straw got shorter, the pitch got
For sound sandwich, students used two large craft sticks, a
thick rubber band, two small pieces of a straw, and two small rubber band. Click here for
more information about the sound sandwich.
Students completed three sound labs. The first was Plucker Up. Students placed a
string tied onto a paperclip into a cup. They put the cup up to their ear and
plucked the string. They changed the length of the string with their fingers. This
The second was King Gong.
Students tied a string to two cups. A hanger was hung on the string. A group
member tapped the hanger and they heard sound through the two cups. This
demonstrated vibrations and sound.
The third was Party Line.
Students connected two cup together, pulled them tight, and talked to each
other. The third person in the group tied a third cup, pulled all three tight,
and talked to each other. The fourth person in the group tied a fourth cup,
pulled all four tight, and talked to each other.
Today was the first Transit of Mercury in ten years. A
transit occurs when Mercury, the Earth, and the Sun are in alignment. You can
see the shadow of Mercury move across the Sun. Students had a chance to observe
parts of it.
Students read the sound text section on sound and completed
Students also completed a sound lab - Tuning Fork Observations.
Students used two tuning forks to demonstrate pitch and vibrations.
Today was the all-day pentathlon. Because so many students
were participating, today students watched an episode of When We Left Earth – A Home in Space.
It presented information about the repair of Hubble as well as the
beginning of the International Space Station. Students completed worksheet while watching the
Students completed a light lab – It's Bent II. Students
were given four different liquids – water, cooking oil, shampoo, and corn
syrup. Their task was to determine if the thickness of the liquid affected
