Why Do Some Animals Hibernate?

Why do some animals hibernate?

Animals hibernate because they need to survive the freezing cold winter and they won’t be able to find food in the freezing cold temperatures as the food will not be available as it won’t be able to grow and  it will die. Or if it's an animal they eat then they won’t be able to find them. If an animal's main source of food is very scarce in the winter, like insects or green plants, it may solve this problem by hibernating.

This deep sleep allows them to gather energy, and survive the winter with little or no food.Most hibernators prepare in some way for the winter. Some store food in their burrows or dens, to eat when they wake up. Many eat extra food while there  is plenty of food. It is stored as body fat to be used later for energy.

The largest hibernators are the bears. Although the bear's heart rate may drop from a normal of 40-50 beats per minute down to 8-12, its temperature drops only slightly, allowing it to wake up quickly. These bears are also unique because, unlike other hibernators, they do not eat or drink at all while hibernating, which can be as long as six months or more.

Anzac Diary Entry

28th April 1915

Dear diary

As I walked onto the battlefields around all  the thousands of  dead Soldiers my heart dropped as I gasped with fear, I then felt miserable and lonely. From then on I really thought deep into how lucky I am to be alive  because my friend has just lost his dad in a plane accident and now he is only left with a mum and a sister which I think is amazing, because I only have a mum and a dad, Our temporary shelter just got blown up and we now have nothing and my friend and I have to make a new one with little resources.

Sadly when we were fighting I shot an enemy straight away they shot back then having my friend behind me I dodged and the bullet went right through his chest. As I looked back at him falling to his death, I then had this huge big gush of brooking hearts spewing threw my guts as I walked towards him and it was too late! since then I have wanted to die myself.

How A Kite Works

Here is my description on how a kite works.

       How  a  kite  works

A kite is a toy for kids that flies in the sky and is powered by wind.

Nylon is a type of fabric and it is used for making kites because it is strong and very light and will fly easily, compared to other fabrics which would be to heavy and won’t be very strong. Kite makers also use bamboo sticks instead of wooden sticks due to the bamboo being light and is also very strong unlike other wooden sticks. String is used on the kite to tie the bamboo and the nylon together and it is also used to control the kite when it is in the air. The bows on the kites are mainly just for decoration on the string coming down from the kite. The hand wheel or nut is used to hold on to witch which has the string  wheeled around it and it controls the kite  when you move it side to side. The tape is used to stick the bamboo and nylon together as well at the string.

    

Things you need

     1.Nylon

     2. Bamboo Sticks

     3. String

     4. Bows

     5. Hand wheel

     6. Tape (optional)

     7. Nut of some sort for weight    (optional)

     8. Scissors

To make a kite you need to grab your sticks and make a cross sign and tie the middle bit together with some string. Then once you have done that you can get your nylon fabric and cut out a triangle shape big enough to have the three ends of the sticks at each corner of the fabric. After that you tie the ends to the nylon or use tape I recommend using tape because it’s more tidier  but its your choise. Then once you have the frame made you then get a piece of string and attach it to the bottom end of the kite as shown above. then you can put bows made out of ribbon and you can stick them on the string.
