Images from a Cell Phone Camera – submitted by Dave Gervais

This is an image of an insect taken from a Huawei p 30 pro cell phone camera. When I compare that to images that I took in 1978 using a really good dissecting microscope with an optical camera, this is incredible. I could easily take these images and identify this insect using a good dichotomous key.

The cost for this cell phone camera is comparable to that of a good dissecting microscope attached with an optical camera, around $ 1400 dollars. Either just with the cell phone, or equipped with the hand held circular motion free tripod, this device could greatly improve field trip images without the need to take specimens back to the lab. What a great purchase for a science department!

 

Question:   Can you identify this insect from the banks of the Ottawa River?  Send your answers to info@stao.org, attention safety committee. Answer will be posted next week.

Scientists may have detected a black hole devouring a neutron star | CBC News

First, astronomers made history when they detected a gravitational wave from two black holes merging. Then it was two neutron stars. Now, astronomers believe they’ve detected a gravitational wave coming from another first-time discovery: a black hole swallowing a neutron star.

A naturalized yard: making a difference – submitted by Dave Gervais

This is a picture of my front lawn. You might see a decided absence of grass. When I first moved here, it took me almost 2 hours to cut the grass in the front and back yard. At my wife’s urging she suggested that we plant trees to make the busy road in front of our house disappear, buffer the traffic noise, and put a stop to the endless cutting of grass.

In addition by selecting some plants natural to the landscape, we have made a difference to this small welcome insect. Win/win…considerably less grass cutting, and a more interesting yard.

Extend that same idea to a school yard, and an ecology field trip could be as convenient as a short walk outside.

Videoconferencing to Connect Students With Science & STEM Experts | STAO Connex by Julie Vander Meij

Technology Focus: Videoconferencing allows you to connect your class live to a guest speaker, to learn from them, and ask them questions. This is enabled through online tools such as Virtual Researcher on Call, Google Hangouts and Skype.

Description: 

 Videoconferencing allows students to connect to science professionals, engineers and other STEM experts and provides relevant real-world contexts and personal stories that help students engage with science curriculum. It can also address STSE expectations (Science, Technology, Society and the Environment) and Strand A expectations.
