Deer fact file
WALT identify and understand main ideas.
Fallow deer Fact File
Males are called bucks, females are called does and young are called fawns.
Males are typically 140-160 cm long and 85-95 cm high at the shoulder. They usually weigh 60-100 kgs.
Does are usually 130-150 cm long and 75-85 cm tall at the shoulder and weigh around 30-50 kgs.
When fawns are born in spring they are about 30 cm tall and weigh around 4.5 kgs.
The life span of fallow deer is 12-16 years provided they aren’t hunted or don’t die in other ways.
The most common coat colour is chestnut, a chestnut coloured coat with white mottles that are much more pronounced in summer and do not show up in winter. The coat is also darker during winter. There is a lighter area around the the tail and the tail is light with a black stripe through the centre.
Another coat colour is menil. On a deer that is menil the spots show a more and are clearly visible all year round. There are no black markings on the tail and the the coat darkens in winter. This colour is more common in wild New Zealand herds than any other herds in the world.
Black: Coat colour is black all year, shading to a greyish brown. No white tail markings or spots.
Leucistic. (White but not albino) Fawns are cream- coloured, adults grow to be pure white, especially in winter.
Only bucks have antlers, during the first two years they are single spikes and from three years onward they are shovel shaped.
Fallow deer are grazing animals, their preferred habitat is mixed woodland or open grassland.
They are agile and fast in case of danger.
They can run at speed of up to 48 mph.
Fallow deer can jump 1.75 metres high and 5 metres long.

DESCRIPTION OF CONTEXT: Investigating ways of transferring energy to cause movement in vehicles | |
BRIEF: Kite Lift Scenario A group were stranded in a building during a flood. Their building was beginning to break up and they urgently needed to be able to reach the nearest building about 20m away, which was more secure. Although the water was deep and fast between the buildings they would be able to be pulled one at a time across to the safe building with a strong rope (and the rope pulled back by a cord for the next person). People in the other building had plenty of strong rope but there was no way to get it across. It had stopped raining and a moderate wind was blowing towards the safe building. On looking through their building all they could find was a considerable quantity of thin but strong cord, some thin bamboo sticks, paper, plastic sheet and sticky tape. Task To make a kite which will be able to be flown over a spot 20m away and either land on it, drop a string as near to the spot as possible, or fly so low as to be within reach or dangle a string within reach (e.g. 2m altitude) of someone standing on the spot.

How to make a model hot air balloon
How to make a model hot air balloon
Model hot air balloons can be good fun to make and fly, however you need to be careful not to catch anything on fire.
Materials:
-light weight plastic bag
-4 straws
-fishing line or light thread
-light cardboard
-4 light candles
-tape
-scissors
-hole puncher (optional)
-a ruler
-a needle (optional)
1.Gather your materials.
2.Take four straws and connect them together into a frame by sticking one end into another.
3.Using as little tape as possible attach the plastic bag to the frame. Try looping the edges of the bag around the frame and using a piece of tape on each side to secure the bag on the frame.
4.Make the candle holder. Cut the cardboard into a 5cm x 5cm square.
5.Cut/punch four holes about halfway from the centre.
6.Make sure the candles fit snugly in the holes. If needed, widen the holes so the candles fit.
7. If you have a needle, thread it with the thread you are planning on using. If not go to step eight.
8.If you don't have a needle, carefully make a small hole in each corner to put the thread through.
9.If you have a needle poke it through each corner and tie. Repeat steps 7-9 in each corner.
10.Make sure each thread is 30cm long.
11.Tie each thread to the balloon, one in each corner, so they are about the same length.
12.Check for tangles and make sure the knots are tight.
13.Double check everything.
14.Find a large, open space to fly your balloon.
15.Wait for a still day, dawn or dusk is best.
16.If you live in a town, or there is any fire danger where you live, it is best to attach a thin, light thread to your balloon before lighting it.
17.Light the candles, making sure the strings or balloon doesn't get burnt.
18.If it works, you can watch it float away. If not you may want to try making it lighter.
19.Pull it down if you tied it up.
20. If you didn't, make sure you find it again.
21.Have fun and improve it!

How do gliders fly?
How do gliders fly?
Gliders are light, unpowered aircraft. They rely on thermals, wave lift and ridge lift to stay aloft. They also played a key part in the inventing of aircraft.
Launching
To get in the air, there are four methods of launching. Aerotowing is one of the most common. It is where a tow plane is attached to the glider by a long rope. The tow plane takes off, pulling the glider with it. The plane takes the glider to the height and location the glider pilot requested and the glider pilot unhooks the rope.
Another common method is the winch launch. Winch launching is where a ground based winch is mounted on a heavy vehicle. The winch quickly pulls in a 1000 - 2500 metre cable made of steel wire or synthetic fiber so the glider rises. When it has risen high enough the pilot undoes it and it sinks to the ground, supported by a parachute.
Auto tows are rarer these days. It needs a hard surface and a strong vehicle attached to the glider by a long cable. First, the driver takes up the slack, then accelerates hard, rapidly rising the glider to heights of about 400 metres.
Bungee launching is where the glider is launched from the top of a gentle hill into a strong wind using a "bungee".The gliders main wheel rests in a small concrete trough. The hook is attached to the middle of the bungee. Each end is pulled by 3 or 4 people. One group runs slightly to the left and the other group runs to the right. Once there is enough tension in the bungee the glider is released and the glider gains just enough energy to leave the ground and fly away.
Flight
Gliders don't have engines so they have to generate lift and thrust another way. Once they've been launched they have to find a way to go up, or their flight won't last long. So, to generate lift glider pilots use thermals, ridge lift and wave lift. They circle around in the thermal, which lifts them up. For example if the glider is dropping 1 metre a second, but the air around it is rising at 2 metres a second, it's actually going up. When they reach the desired height they leave the thermal, and soar away. The first glider to enter the thermal chooses the direction, all the other gliders must go that way. To measure the performance of a glider you use its glide ratio. Glide ratios measure how far the aircraft can glide to the amount it drops. For example some modern gliders can have glide ratios better than 60:1 (60 miles gained, 1 mile dropped).
History
Gliders were invented by Sir George Cayley in 1853 and the Wright brothers. The sport of gliding only emerged after WWI. Germany was, and still is one of the most successful places for gliding. So in the 1920s - 1930s while aviators and aircraft makers in the rest of the world were trying to improve powered aircraft, Germans were making and flying ever more efficient gliders. The first German competition was held in 1920. The record time was 2 minutes and a world record distance of 2 kilometres. Today, at last count there were over 111,000 active pilots, and around 32,920 gliders.
Conclusion
Gliders were one of the first successful aircraft forms. They have changed a lot since they were first flown. They are still widely used but usually for recreation and competition use.
