Field Trips
- Wednesday, May 7 (8:45-3:15) Oakland Museum History Gallery
- Friday, May 23 (8:45-3:00) Sailing on Bay and nautical skills workshop.
- Thursday, June 5 (7:45-4:30) Marshall Gold Discovery State Park, Coloma CA
- New Field Trip: On June 5 we are headed to Gold Country! We have an early departure of 7:45am and a late return of 4:30pm (traffic depending). We will need drivers. It is a long drive, but a fun trip. We will explore and tour the town, visit the museum and Sutter's MIll, followed by panning for gold in the South Fork of the American River.
Today in Strawberry: Flaming Science? Thanks to science guru Jeff Sandler in the middle school, we had an exciting set of demonstrations as a finale to our chemistry unit. The demonstrations included chemical and physical changes including the formation of precipitates, color change, disappearing foil, expanding soap, smoke, fizz and fire! Along with the dramatic changes to observe, the students discussed what they thought was happening in each demonstration and are now writing a report demonstrating their understanding about one of the reactions from today. We will reveal more of the chemistry behind the demonstrations after the students have a chance to finish writing about them.
Demonstration 1: Two clear liquids combine to instantly form a yellow substance surrounded by oily-like liquid.
That's not orange juice!
Demonstration 2: Copper chloride and aluminum foil.
Taking the temperature of the copper chloride. This was followed by a large piece of
aluminum foil being stirred into the solution. The foil fell apart and disappeared into
the liquid which rapidly changed from blue to grey.
The blue liquid transformed to become clear and foggy, with a large deposit of
brownish red substance on the bottom. We will reveal what happened after the students
have a chance to theorize and write about their observations.
Demonstration 3: Liquid Glycerin and Potassium Permanganate powder
First, the glycerin was added to the powder. Nothing seemed to happen.
Then, fizzles and smoke . . . and then . . .
It burst into flame. Whooee, now that's science!
And, boy did it stink. We took an outside break after that.
Demonstration 4: Ivory Soap and a microwave!
We placed a bar of Ivory soap on a dish and put it in the microwave for a minute.
We watched it rise and expand into a puffy glob.
The glob of Ivory soap.
Hope to see you tonight at the sing!
