There’s a saying that “it’s not the volts that kills you, it’s the amps” and while that’s true in a way, you can’t have amps without volts and skin resistance plays a big part too. This video explores all this, introducing voltage, current and resistance for those new to these things. Continue reading →
They knew it had to exist, but they just couldn’t find evidence of it. Now, after decades of searching, astrophysicists have found verification of the first molecule that formed after the Big Bang. Continue reading →
We have just seen the first image of a black hole, the supermassive black hole in the galaxy M87 with a mass 6.5 billion times that of our sun. But what is that image really showing us? This is an awesome paper on the topic by J.P. Luminet: Image of a spherical black hole with thin accretion disk Astronomy and Astrophysics, vol. 75, no. 1-2, May 1979, p. 228-235 https://ve42.co/luminetContinue reading →
Scientists have found evidence of a major solar storm that struck Earth more than 2,600 years ago — a finding they say holds relevance today, given how vulnerable some of our modern technology can be to the sun’s activity. Continue reading →
Peergrade.io is a free website that allows teachers to provide a rubric for students to use assess peer assignments. The website allows teachers to see student assignments and the feedback they provide to their peers, while keeping everything anonymous for the students. Continue reading →
Investigating the effects of humans on the local school ecosystem using the Google Suite for Education with SNC1P students
Using the power of Google Forms and Sheets to create large datasets that allow for a rich analysis of student-collected inquiry data.
Students will fill out a Google Form on the ecosystem data that they collect, which will then be exported into a Google Sheet and analyzed so that students can see trends in their class’s dataset without much effort on either the student or teacher’s part. The students are empowered to analyze their own data while teacher is a guide on the side.
