Some New, Some Old

Posting some new projects in the works, and some that were already mentioned (new video to view though).  We spent the Friday with a two hour delay planting the germinated Spartina seeds into containers while others constructed the first PVC greenhouse tent that will rest on our raised flower beds.  We’ll take some of the Spartina to the high school’s greenhouse, but thought we could make our own mini versions for BSE’s campus.  Plus it was a great tie in with fractions and measurement.  Who knew that what you learn in school could actually be applied?  More pictures will be added to this post in the days/weeks to come.  It took about a week to create one tent (excluding sheeting).  We still need a few connectors to run our pipe along the ridge of the roof.  They did great working as teams and measuring thrice before cutting.  I think my PVC cutter is on it’s last run.  That brackish water though . . .  sulfur egg fart.  Fifth grade teachers were popping in asking if the septic had broke in the science lab restrooms.  Photography exclusively taken by Natalie.

Echolocation & Interpreting Data

Thanks to the good folks at the Center for Marine Sciences & Technology (@CMAST) and The Science House (@THS_CMAST) for loaning their Vernier technology, allowing our young minds to  . . . a.) explore how bats and dolphins use echolocation, detecting distances of objects based on reflecting sound.  & b.) interpreting data waves results.

The Go!Motion devices were very simple to use, just a USB plugin into the back of the chromebook, and operated smoothly by downloading a free app known as Logger Lite.  Our first day we became familiar with operation of Go!Motion by placing a book or hand in front of the screen and then raising it away and/or towards quickly and/or slowly, the data is tracked as the motions are made.  The device serves as a bat while the object moving is the insect.  They were able to distinguish when a bat would determine if another object were near or far away by the rise or decline in the graph.

For the next act students took turns operating and standing in place to find the distances (marking points) of half a meter and 2 meters in which the kids had to interpret where they were standing and adjust position to the correct measurement.  These marking points served for the experiments of walking away from and toward Go!Motion.  A neat-o feature is the zoom in on the graph, allowing the kids to see if they ruffled their pant leg or twitched a finger while standing still.  It was a real eye opener to see the bounces in the waves according to the slightest movements.  The jumping up and down activity was a hit.  According to the wave data we might have some high fliers by the time they are in their teens.  Just throwing that out their for any college basketball or high jump recruiters that stumbled upon our blog.
