The magic triangle
A triangle can be made by arranging 4 shapes on a 5 x 13 grid.
By re-arranging the shapes a new triangle can be made.
The pieces in the lower triangle are exactly the same as those in the upper triangle, but now seem to take up less space so there is one blank square
Where does the white square come from?Hover your mouse here for the solution

4 litres of water problem
You are camping be the edge of a stream and a recipe calls for EXACTLY 4 litres of water.
Unfortunately you only have two empty containers, one that holds 3 litres of water and one that holds 5 litres.
How can you get exactly 4 litres (you can fill and empty the containers as many times as you like using water from the stream).Hover your mouse here for the solution

Flying over planet Earth
A time-lapse taken from the front of the International Space Station as it orbits our planet at night. This movie begins over the Pacific Ocean and continues over North and South America before entering daylight near Antarctica. Visible cities, countries and landmarks include (in order) Vancouver Island, Victoria, Vancouver, Seattle, Portland, San Francisco, Los Angeles. Phoenix. Multiple cities in Texas, New Mexico and Mexico. Mexico City, the Gulf of Mexico, the Yucatan Peninsula, El Salvador, Lightning in the Pacific Ocean, Guatemala, Panama, Colombia, Ecuador, Peru, Chile, Lake Titicaca, and the Amazon. Also visible is the earths ionosphere (thin yellow line), a satellite (55sec) and the stars of our galaxy. You can also see flashes of lightening from storms.
The Aurora Australis
Here’s a video of the Aurora Australis (Southern Lights) using shots taken by astronauts aboard ISS.
(In the Northern hemisphere we are more familar with the Aurora Borealis or Northern Lights which are seen over the North Pole)
The green above Earth are energetic aurora – as seen from ISS while it flew 225 miles over the southern Indian Ocean on September 17, 2011. This 34-second video actually spans about 23 minutes of time.
The Aurora is an incredible light show caused by collisions between electrically charged particles released from the sun that enter the earth’s atmosphere and collide with gases such as oxygen and nitrogen. The lights are seen around the magnetic poles of the northern and southern hemispheres.
Some videos from NASA
These videos could be used as a starting point for a PowerPoint project on Global Warming
NASA have an app to let you look at their huge collection of images (over 15000) and videos.
Come explore with NASA and discover the latest images, videos, mission information.
I am not trying to endorse any of the products shown, but just trying to show you that inventing things is easy.
If you have an idea talk to your Sciuence or Technology teacher and see if he can help you make a prototype.
