I ran one… FOR SCIENCE!

Don’t miss our next video! SUBSCRIBE! ►► http://bit.ly/iotbs_sub

So maybe we can't outrun cheetahs or antelope, but humans are uniquely adapted for long distance running. What does science have to say about marathon running? To find out, (and because I was feeling a little crazy) I decided to run one!

Here's what I discovered about the science of long distance running

A short introduction to the chain rule as well as three examples.

Two examples include functions that only contain two nested functions. The final example goes over how to use the chain rule when a function contains three or more nested functions.

This chemistry video tutorial provides a basic introduction into Le Chatelier's Principle of chemical equilibrium. It explains how to determine which direction the reaction will shift if the concentrations of the reactants or the products increase in value. It discusses the effect of adding a catalyst or an inert gas on the position of equilibrium. It also discusses the effect of changing the volume and pressure on equilibrium.

Bruce the bear likes to keep to himself. That, and eat eggs. But when his hard-boiled goose eggs turn out to be real, live goslings, he starts to lose his appetite. And even worse, the goslings are convinced he's their mother. Bruce tries to get the geese to go south, but he can't seem to rid himself of his new companions. What's a bear to do?

Using paper, paper clips and tape, student teams design flying/falling devices to stay in the air as long as possible and land as close as possible to a given target. Student teams use the steps of the engineering design process to guide them through the initial conception, evaluation, testing and re-design stages. The activity culminates with a classroom competition and scoring to evaluate how each team's design performed.

We try not to get into too much great man history here at Crash Course, but we have to admit: Napoleon Bonaparte is a pretty big deal. Join us as we track the rise, further rise, fall, rise, fall, mortal fall, and posthumous rise of Napoleon. This guy changed France, he changed Europe, and in a lot of ways he changed the world.

In the 17th century, as the British colonies in the Americas were getting established in places like Jamestown, VA, the system of chattel slavery was also developing. Today, we'll learn about the role that slavery played in early American economy and how slavery became a legally accepted practice in the first place, and how it contributed to the colony’s early economic success. We'll look at the experiences of Anthony Johnson and John Punch to see how legal precedents that greatly influenced the development of slavery were set.

Students are introduced to renewable energy, including its relevance and importance to our current and future world. They learn the mechanics of how wind turbines convert wind energy into electrical energy and the concepts of lift and drag. Then they apply real-world technical tools and techniques to design their own aerodynamic wind turbines that efficiently harvest the most wind energy. Specifically, teams each design a wind turbine propeller attachment. They sketch rotor blade ideas, create CAD drawings (using Google SketchUp) of the best designs and make them come to life by fabricating them on a 3D printer. They attach, test and analyze different versions and/or configurations using a LEGO wind turbine, fan and an energy meter. At activity end, students discuss their results and the most successful designs, the aerodynamics characteristics affecting a wind turbine's ability to efficiently harvest wind energy, and ideas for improvement. The activity is suitable for a class/team competition. Example 3D rotor blade designs are provided.

Today we’re going to read David goes to School by David Shannon.

David’s teacher always said...No, David! No yelling. No pushing. No running in the halls.

David! You’re tardy!

Sit Down, David!

Don’t chew gum in class!

David, raise your hand!

Keep your hands to yourself!

Pay attention!

Wait your turn, David!

I don’t care who started it!

David! Recess is over!

Shhhhhhhh!

Again?

That’s it, Mister! You’re staying after school!

David, have you finished?

Good job, David!

Yes, David… You can go home now.

When we tell a story, we must follow the right order - and to indicate this order of events, we can use sequence words. In this instructional video, Owen talks about these sequence words and gives an example of how to structure a story correctly, using them.

This video is part of a broader lesson plan that is aligned with CCSS.ELA-Literacy.CCRA.W.3: "Write narratives to develop real or imagined experiences or events using effective technique, well-chosen details and well-structured event sequences."

Please visit Snowflake.live to access the complete lesson plan, an educational interactive game and other related resources.
