A Dinosaur Blog

First we mixed 1/3 Plaster Of Paris and 2/3 of water into a cup and mixed it up, We then added in a small plastic dinosaur and waited 2 days so that our Plaster of Paris would be rock solid. After 2 days have passed we got some nails and a hammer and we dug up our Dinosaurs. It was very messy but it was fun. It went all over our hands and all over the floor. Sadly some peoples Dinosaurs experiment did not work.

Definitions :

Lift: The air pressure is underneath the wing than above and the aircraft / bird flies.

Drag: The force than effects the speed of an aircraft/bird. It can slow down.

Thrust: The forward movement of an aircraft/bird.

Weight : The downward force of an object when it is above the earth

Aerofoil : The shape of the wing on aeroplanes and some birds.

Bernoulli effect: when a wing is in a shape of an aerofoil the pressure builds up underneath

 it and lifts the aeroplane up.

What happened ?

when the light shone on the plastic and the mirrors it bounced back and shone in different directions making a concert light affect. We had heaps of different shapes and sizes in the plastic shapes and mirrors.They all made a affection lines and some even made shapes.

Science - Kites

Aim: To look at a kite and how we can overcome the 4 forces of flight.

Forces of flight with Kites

Force	Increase / decrease	How do we do this when making a kite?
Drag	Decrease	We need to make sure it is pointed. We need to make sure it is angled correctly to the wind.
Lift	Increase	Longer string, Face into wind.
Gravity	Decrease	We make it streamline, And light material.
Thrust	Increase	Strong and steady wind.

Write a definition about the following types of kites and find a picture of them that you can upload to your blog.



1.The Sled Kite =A Sled kite with inflatable spars is probably seen more now than the traditional 2-stick variety

2. The Diamond Kite = In terms of the structural design of Diamond kites, there's not much to say. It just hasn't changed much for centuries! But very broadly speaking, these kites have seen 3 phases over time.

3.The Barn Door Kite = Since Barn Door kites can flat or bowed, and made with a range of quite different proportions, there is considerable variation in their stability in the air.

4.The Sode Kite =The Sode kite, or Sode Dako as it's known in Japan, is also known as the Kimono kite. 'Sode' actually means 'sleeve of a kimono'.

5. The Delta Kite = Small Deltas from retail outlets or kite shops are a popular choice for kids!
