Augmented Reality

Technology, and how it is used, is one of parent's main concern when it comes to their children. and while the world wide web is home to many different dangers, the benefits we can achieve from it are endless. As of today there are thousands of new up-and-coming applications that we can use to make presentations easier, and one of these applications is Aurasma. 

Aurasma is an augmented reality reality app that, at first, may seem hard to understand, but has a really simple concept. The process to create an Aurasma is the the following. First, we find an image to connect to a video. Then we create the video and through a series of steps we intertwine the two to create an augmented reality that anyone with the Aurasma app can visualize.

What my seventh grade class did was choose a scientific topic and, after researching and analyzing it, we created a poster displaying our conclusions on the topic and what we investigated. Then we made a three minute video ( the app limits the video size that you can use) and connected it to the poster. This allowed anyone that followed our Aurasma channel to be able to see the video come up when they focused the app's camera on the poster.

This is not only an easy way to make a presentation, but it also saved the class from the nervousness of presenting in front of a live audience. And now that you know how to use the app, you can use it on any subject or at work and make your life a little bit easier.

Divisibility Rules

2. the last digit has to be 8,6,4,2, or  0.
3. the sum of the digits has to be multiple of 3
4. the last two digits have to be multiples of 4
5. the last digit has to end in either 5 or 0
6. the number has to be divisible by both 2 and 3
9. the sum of the digits have to be multiple of 9

Why is the force of gravity not exactly the same everywhere on Earth's surface?

Because the force of gravity is stronger as it nears the center of the Earth and because the Earth is not completely flat, gravity is bound to change depending on your location. Ex:. Gravity is going to be less stronger on the peak of Mt. Everest than at the bottom.

Basic concepts of Geometry

Geometry

Geometry began with a practical need to measure shapes. The word geometry means to “measure the earth” and is the science of shape and size of things. 

Undefined Terms

An ‘undefined term’ is a term or word that doesn’t require further explanation or description.  It already exists in its most basic form.  These basic terms are used to define or explain more complicated terms or concepts.

Point

A point is the most important and basic concept of geometry. It is represented as a dot with a capital alphabet which is its name.

Line

 A line is a set of points and it extends in opposite directions on forever. It is represented by two points on the line and a single alphabet in the lower case.

Plane

A plane is a flat surface that extends in all directions on forever. A plane has no size and definitely no shape. However it is represented as a quadrangle and a single capital letter.

Collinear and Coplanar

Three or more points are said to be collinear if a single line contains all of them. Otherwise they are said to be non collinear.

Postulates

Postulates are statements the validity or truth of which are assumed without proof.

Theorems

In mathematics, a theorem is a statement that has been proven on the basis of previously established statements, such as other theorems, and previously accepted statements, such as axioms.

Angles

An angle is a figure formed by two rays with a common endpoint, and which are not on the same line. 

What would happen if we had no moon?

There would be no lunar tides. The earth could get hit by asteroids more often because the moon sometimes blocks their path. The earth would spin slower because the earth´s rotation is being slowed down through tidal interactions with the moon. It would´ve been awfully dark at night, obviously. There would be shorter days and a more extreme climate.

National debt: 21,989 million dollar

Number of habitants: 10 million

If we divide the national debt by the number of habitats then we could get the amount of money a child would owe at the time of birth

Result: 2198. 9

Assessment questions

1. What force is needed to accelerate an object 5m/s2 if the object has a mass of 10kg?

Force= Mass x Acceleration

Mass: 10kg Acceleration: 5m/s2   =     10x5= 50N

2. Carlos pushes a 3kg box with a force of 9N. The force of friction on the box is 3N in the opposite direction. What is the acceleration of the box?

9N- 3N= 6N   3kg x 6N = 18 m/s2

Carlos and Sarah are playing a game in which each player either wins, loses, or draws at each turn. The winner of a turn is awarded 5 points, the loser loses 5 points, and if it’s a draw 0 points are awarded. For the first 8 rounds Carlos had the following result: lose, win, lose, win, win, lose, win, and draw.

What is Sarah’s point total?  

Sarah’s wins: 3

Sarah’s losses: 4

Draws: 0

3x5= 15  -5x4= -20  15+(-20) = -5

Sarah’s point total is -5

Richard was at the canyon and he shouted his name down the canyon, 8 seconds later he heard his echo. How deep is the canyon?

If the speed of sound is:

340.29 m / s

Then we multiply 340.29 times 4:

1361.16
