TO EXPLORE IN AUGMENTED REALITY:
1) Open up GeoGebra 3D app on your device. [br][br]2) Go to MENU, OPEN. Under SEARCH, type [b]rascu98w[/b].[br] Note these characters can be found in the URL above.
STUDENTS:
Once you're all set up, please answer the questions located below this applet.
1.
[color=#bf9000][b]Note the equation of the plane is z = some constant. [/b][/color][color=#bf9000][b]Change the equation of this yellow plane to z = 2. [br]Then change it to z = 1. [br]Then change it to z = 4. [/b] [/color][br][br]How would you describe the intersection of this [b][color=#bf9000]plane[/color] [/b]and [color=#1e84cc][b]double-napped cone[/b][/color]?
2.
Change the [color=#bf9000][b]equation of the plane[/b] [/color]to [math]z=x+2[/math] . How would you describe the intersection of this [color=#bf9000][b]plane[/b][/color] and [color=#1e84cc][b]double-napped cone[/b][/color] now?
3.
Change the [color=#bf9000][b]equation of the plane[/b] [/color]to [math]z=0.5x+2[/math] . How would you describe the intersection of this [color=#bf9000][b]plane[/b][/color] and [color=#1e84cc][b]double-napped cone[/b][/color] now?

Surface of Revolution: 3D Augmented Reality Template

Here, you can use this template to create a function ([b]f[/b]), and rotate it about the xAxis (by using the [b]n[/b] slider). The [b]Filling[/b] slider adjusts the opacity of this surface. [br][br]Note the [b][color=#e06666]surface of revolution[/color][/b] formed. [br][br]You can change the phrase "xAxis" to "yAxis" to rotate the graph of function [b]f [/b]about the yAxis instead.
TO EXPLORE IN AUGMENTED REALITY:
1) To explore in Augmented Reality, open up GeoGebra 3D app on your device. [br][br]2) Go to the MENU (horizontal bars) in the upper left corner. Select OPEN. [br] In the Search GeoGebra Resources input box, type [b]qgcz82ae[/b][br] (Note this is the resource ID = last 8 digits of the URL for this resource.)[br][br]3) Position what you see accordingly on your device.

3D AR Modeling Challenge 1

STUDENTS:
The goal of this first modeling challenge is to build this trash can (shown in this screencast below) using the tools of GeoGebra's 3D Graphing Calculator. If your device has [b][color=#9900ff]ARCore by Google[/color][/b] installed on it, you can then explore this model within GeoGebra Augmented Reality! [br][br][b]Question to consider: [/b][br]What 2 solids compose this trash can model? [b][br][br]Modeling Clues:[br][/b]For this particular trash can, the height of the [b][color=#1e84cc]blue surface[/color][/b] is three times the radius of the [b][color=#a64d79]red/pink surface[/color][/b].

Season Changes: Sun-Earth Demo

Even though the [b][color=#bf9000]Sun[/color][/b] and [b]Earth [/b]are not constructed to scale (nor is the distance between the centers of these two masses) , the [b]Earth[/b] (shown here as [b][color=#1e84cc]northern hemisphere[/color][/b] and [b][color=#ff00ff]southern hemisphere[/color][/b]) does have an axis that is tilted approximately 23.5 degrees about its center with respect to the line that is perpendicular to the plane containing its orbit.
1.
For the hemisphere in which you live, what Sun-Earth event does [b][color=#ff7700]point A[/color][/b] represent? [br]What does [b][color=#ff7700]point B[/color][/b] represent? What about [color=#ff7700][b]point C[/b][/color]? What about [b][color=#ff7700]point D[/color][/b]? [br][br]Give reasons for your responses.
