The largest pterosaurs like Quetzalcoatlus were closer in size to airplanes than birds. No flying animal alive today comes close to their huge size. So did giant pterosaurs actually fly? I went to see the fossil bones of the largest pterosaur that ever lived so I could learn how these winged giants actually took to the skies.

Our home is burning. Rapid climate change is destabilizing our world. It seems our emissions will not fall quickly enough to avoid runaway warming and we may soon hit tipping points that will lead to the collapse of ecosystems and our civilization.

While scientists, activists and much of the younger generation urge action, it appears most politicians are not committed to do anything meaningful while the fossil fuel industry still works actively against change. It seems humanity can’t overcome its greed and obsession with short term profit and personal gain to save itself.

And so for many the future looks grim and hopeless. Young people feel particularly anxious and depressed. Instead of looking ahead to a lifetime of opportunity they wonder if they will even have a future or if they should bring kids into this world. It’s an age of doom and hopelessness and giving up seems the only sensible thing to do.

But that’s not true. You are not doomed. Humanity is not doomed.

Why does shaken soda explode? Does ice melt first in fresh or salt water?

This video features experiments that have been shown to me by science teachers over the years. Does ice melt fast in salt water or fresh water was an experiment introduced to me at the Utah Science Teachers' conference. The ring of metal over a chain demo came from a teachers event in Florida. The idea shaking a carbonated drink increases pressure came from an email.

Special thanks to Petr Lebedev for building the pressure gauge.

You can easily create your own custom #GeoGebra Activity before creating a GeoGebra Class from it. This quick (silent) demo shows you how to do this. This URL contains quick links to activity templates containing blank GeoGebra apps: https://www.geogebra.org/m/hnc....rgruu#material/rkhby Each link contains one of our apps from which you can create your own activity.

In this lesson we will look at an arithmetic sequence which is part of grade 12 patterns. An arithmetic sequence is a sequence which contains a constant difference between the terms.
