An old video of Convection Currents

G. I enjoyed watching this show with my kids years ago; while we sit at home for these next few weeks, I think we are ready for a re-watch.

F. It's Friday night. The science video for you all is all about transferring the chemical energy in food to mechanical energy in your bodies. It's important to stay physically fit and active during these strange days. Here is a video I'm converting chemical energy into mechanical energy to at the moment. :)
E. Bioluminescent Mushrooms!
Observation: I see fungi glowing green.
Inference: I infer they are are doing this for a very specific reason, as most fungi do not radiate luminescence.
Additional Questions: Why do they they do this? Why don't all fungi do this? Why doesn't the mushroom on my pizza radiate green light? Why is the bioluminescence green? Why not orange, purple?
D. Satisfying Slow Mo Fruit Ninja - The Slow Mo Guys
Prediction: I predict that someone is going to be hit in the face with a piece of fruit.
Observation: I saw someone get hit in the face with a fruit.
Inference: I bet that hurt.
Additional Thoughts: I remember reading once that tomatoes are both fruits and vegetables. I wonder how much they spent on all of that produce. I wonder which of my students would enjoy throwing fruits at me...???
B. Natural Climate Cycles | Polar Extremes
Natural Climate Cycles | Polar Extremes
Q/A
1. What is the difference between weather and climate?
2. What makes the seasons here on Earth?
3. When the sun is tilted towards the northern hemisphere, we experience ______.
4. During he southern hemisphere summer, we in the north experience ______.
5. Weather/Climate changes on a daily basis, whereas Weather/Climate is influenced by the movement of the earth around the sun and is studies on a long term basis.

C. What Happened Before History? Human Origins
Prediction: I bet life was colder, hotter, more dangerous and much more smelly/malodorous/foul smelling/stinky!
Observation: For most of human history, life was CHALLENGING.
Inference: Based on human history, we have a lot to be thankful for today.

A.
Taking the Heat
In his pursuit of strong materials, David Pogue, technology columnist and host of NOVA's "Making Stuff," wants to know how firefighters dress to boldly enter blazing buildings. In this video, Pogue visits with chemist Rich Young of DuPont to see how a material called Nomex withstands heat and flame.
Q/A
1. What is the Independent Variable? Dependent Variable? 3 Constants?
2. Why would the outcome of this experiment benefit firefighters?
3. Would this Nomex make a good conductor of heat or insulator of heat? Explain your response.
4. Would this sort of heat transfer be primarily conduction, convection or radiation?
HINT: You have to watch the Is fire a solid, a liquid, or a gas? video first, from GC.
