Test email video clip

This is a video clip of a Rare Endangered Cape Parrot. It was filmed in Hogsback Eastern Cape. These birds are the only parrot endemic to South Africa. The vidio clip is of a Cape parrot nesting site. Although the bird is small, the parrot call is clearly audiable.

The Sunset Shows

The Sunset Shows are very interesting and are usually different each time. This time we got told about the different forms of substances and we got shown two examples of them.

First we got shown Dry Ice, you would never guess what dry ice is if you don’t know. Dry ice is a solid form of carbon dioxide and it has a temperature of –78.5 degrees Celsius! Dry ice is not as hard as ice and is white in colour; it also dissolves into the air very quickly.

The second example we got shown was liquid nitrogen. Liquid nitrogen is a liquid form of nitrogen (which you can easily tell from the name). Liquid nitrogen has a temperature of –196 degrees Celsius. At the Sunset Shows a few things got put in Liquid nitrogen including a marshmallow, a banana and a balloon. The marshmallow was soft before it went in and hard & crumbly when it came out. The banana was soft when it went in and was hard when it came out. The balloon was big when it went in and it looked like it had very little air in it when it came out but t very quickly got its size back.

The Sunset shows are very enjoyable and are a nice way to spend the late afternoon(s).

Learning about satellites

Learning about satellites

The satellite workshop was truly amazing. We learned lots of new information, and how important the satellites are. The human being has become totally dependent on satellites.
The military, weather station, maps of the world, the astronomists would be so much behind if they would not have satellites.
Smaller satellites are about 150cm3 big, the biggest existing satellite is about 30m3 big and weighs 7t, the International Space Station. It costs about 300-400 million US$ to make a satellite and send it to space.
The TT&C, Satellite Tracking Telemetry and Command, checks that there are no problems with the satellite before it gets send to space by a shuttle.
There are three types of satellite:
LEO(Low Earth Orbit): 160 to 1000 km above Earth. It travels 28162km/h. It observes Earth.
MEO(Medium Earth Orbit): It travels iv 4-6 hours around the Earth. It also observes Earth. The speed is changing.
GEO: Circles the Earth in 24 hours. It travels the same direction as the rotation of Earth. It travels in 390000km/h. It is a Communication Satellite.
The South African Satellite is called Sumbandilasat, which stands for Pathfinder. It is an Earth Observation Satellite.
3-4 year old satellites get send to sun and blow up. It is cheaper than getting it back to Earth.

Soap-box Darby

The soap-box Derby is designing, building and racing a go-cart. You have to design a nice go-cart so that it can be comfortable and fast at the same time. All the go-carts were unique in their own ways. It was lots of fun to do the soap-box Derby plus we won great prizes.
