**1.TREASURE HUNT**

A treasure hunt is one of the most popular and simple activities used by teacher involving the internet. It consist of a paper or a web page with a series of questions and also a list of webpages in wich students look for answers. Finally, we should include the "Great question", wich answer does not appear directly in the web pages, and should assess what students have learned during the process of searching. thet are useful strategies to adquire information about an specific subject, and also to practice abilities related to technology and internet.

**2.MAP PROJECTION **

A map projection is a mathematically described technique of how to represent the Earth’s curved surface on a flat map. To represent parts of the surface of the Earth on a flat paper map or on a computer screen. It has to be represented using a grid of lines of latitude and longitude. In the entire world there are differents ways of projecting maps...

**3. ROBINSON PROJECTION**

The Robinson projection is a map projection of a world map which shows the entire world at once. He didn't use mathematical formulas for his projection, but tabular coordinates to make the world look good. The map divides lines of latitude and longitude throughout the projection. All lines appear curves, except for the straight line lenght in the middle of the map that passes through the central meridian.

**4.MERCATOR PROJECTION**

It is often described as a cylindrical projection, this projection is created based on mathematical operations... This projection is usually used for navigation charts, because any straight line on a Mercator projection map is a line of constant true bearing that enables a navigator to plot a straight-line course. It is less practical for world maps because the scale is distorted.

**5.AZIMUTHAL PROJECTION**

The azimuthal projection consists in projecting a portion of the Earth on a plane tangent to the sphere at a selected point, obtaining the vision that would be achieved either from the center of the Earth or from a poing in space outer. The azimuthal projection is a projection geographical
characterized by radial symmetry around the center point. In this kind of projection we can find different
types such as: orthographic, stereographic,
gnomonic, equidistant...

Hello guys!! We loved the presentation you did, it was very clear explained and it was such a good idea to make a map and passed it around the class. Well done! Best wishes for next taxt, x The Chalkies x Come visit us! http://chalkies7.blogspot.com.es/

thechalkiesel 26-02-2016Hi guys! I´m Juan from The Prickles and I´m the journalist for this week. First of all nice post. I thought that your presentation was good and I liked the idea of the of the poster with the comparisons of the map projections. If I have to tell you a negative thing is that we could not see properly the exposition due to the projector. Such a pity :( !
