Bonus! In this video we'll connect the degree of these curves to the number of control points in the construction.
Now we are ready to ray trace in 3D. We'll look at the problem of ray triangle intersection.
Finally, let's bring our parabolic arc to life!
Now it's your turn to drive. In this video we'll present you with a casting challenge to complete using everything we've learned so far.
Review of how to write a function (starting with translation)
Why do we divide the number of combinations by the number of permutations?
Try out your deformers on a face.
Finally we'll need to rotate object to finish our scene.
The arts reflect the society that creates them. Nowhere is this truer than in the case of the ancient Greeks. Through their temples, sculpture, and pottery, the Greeks incorporated a fundamental principle of their culture: arete. To the Greeks, arete meant excellence and reaching one's full potential.
In this video we hack apart a bread board to create a 5 volt power distribution strip. The 5 volts comes from the center pin in the motor controller and the negative or ground comes from the ground pin on the motor controller. Created by Karl Wendt.
Now we just need to determine whether our intersection point is inside or outside the triangle.
The goals of OpenSciEd are to ensure any science teacher, anywhere, can access and download freely available, high quality, locally adaptable full-course materials. REMOTE LEARNING GUIDE FOR THIS UNIT NOW AVAILABLE!
This unit on weather, climate, and water cycling is broken into four separate lesson sets. In the first two lesson sets, students explain small-scale storms. In the third and fourth lesson sets, students explain mesoscale weather systems and climate-level patterns of precipitation. Each of these two parts of the unit is grounded in a different anchoring phenomenon.
Let's put everything together. Get ready for a really powerful formula: the binomial coefficient (warning: you may need to watch this a few times!).
Time to get a little mathy. Let's look at the general form for any transformation.
Review how to connect our deformers and shapes together
In this part of the unit, students are exploring how global temperatures have changed over the past hundred years. Students will examine tables and graphs about global temperatures and carbon dioxide levels, human consumption of food, and human consumption of natural resources. They will find patterns in the graphs. Based on this data, students will construct an argument about how human activities (increase in population and consumption of natural resources) cause global temperatures to increase.
Vicki Lombardi's 6th grade students at Santa Rita Elementary in Los Altos School district learn how to build a Spider robot. Read more at: http://lasdilearn.blogspot.com/2013/02/third-graders-building-robots-mission.html. Created by Karl Wendt.
This unit on metabolic reactions in the human body starts out with students exploring a real case study of a middle-school girl named M’Kenna, who reported some alarming symptoms to her doctor. Her symptoms included an inability to concentrate, headaches, stomach issues when she eats, and a lack of energy for everyday activities and sports that she used to play regularly. She also reported noticeable weight loss over the past few months, in spite of consuming what appeared to be a healthy diet. Her case sparks questions and ideas for investigations around trying to figure out which pathways and processes in M’Kenna’s body might be functioning differently than a healthy system and why.
Students investigate data specific to M’Kenna’s case in the form of doctor’s notes, endoscopy images and reports, growth charts, and micrographs. They also draw from their results from laboratory experiments on the chemical changes involving the processing of food and from digital interactives to explore how food is transported, transformed, stored, and used across different body systems in all people. Through this work of figuring out what is causing M’Kenna’s symptoms, the class discovers what happens to the food we eat after it enters our bodies and how M’Kenna’s different symptoms are connected.
This is an online module created for the 3rd Grade of the Junior High School. The topic of the lesson is the "7 Wonders of the World", and its main emphasis is placed on the Listening comprehension skills practice.
Oh, no! I’ve dropped my phone! Most of us have experienced the panic of watching our phones slip out of our hands and fall to the floor. We’ve experienced the relief of picking up an undamaged phone and the frustration of the shattered screen. This common experience anchors learning in the Contact Forces unit as students explore a variety of phenomena to figure out, “Why do things sometimes get damaged when they hit each other?”
Student questions about the factors that result in a shattered cell phone screen lead them to investigate what is really happening to any object during a collision. They make their thinking visible with free-body diagrams, mathematical models, and system models to explain the effects of relative forces, mass, speed, and energy in collisions. Students then use what they have learned about collisions to engineer something that will protect a fragile object from damage in a collision. They investigate which materials to use, gather design input from stakeholders to refine the criteria and constraints, develop micro and macro models of how their solution is working, and optimize their solution based on data from investigations. Finally, students apply what they have learned from the investigation and design to a related design problem.
