Why popcorn pops


Why popcorn pops


Introduction
Popcorn is a delicious snack but have you ever wondered how and why it pops, well you are in luck because in this informative text you will learn how piquant popcorn pops.

Middle

paragraph 1-hard shell 
A popcorn kernel (or seed) is corn, but not the regular corn we would eat at a barbecue. It is a different species (type) of corn. A kernel is a small seed, the outside part is called a hull. The hull is a hard shell that protects the seed. 



Paragraph2-the pop
As the popcorn is heated, the water turns into steam, which builds pressure inside the kernel. When the hull can no longer contain the pressure POP!  the kernel explodes, and a fluffy new piece of popcorn is born. 

Paragraph 3-inside the hull
Inside the hull, there are many things to learn. The white stuff inside the popcorn kernel is actually starch. That bit is also called the endosperm. It is the seeds fuel.  Beneath that is the germ where it feeds on the endosperm. So that is how it will grow into a plant. 


Conclusion
Popcorn is basically steam rushing out where it pops and grows into popcorn. When it pops it is the sound of steam shooting out of the kernel. Next time, before you eat popcorn, study how all of the science works.

physical change definition

Physical change


Physical change is when you change the shape of an object but can usually change the thing back to how it was before.

An example of physical change is when you turn paper into an airplane 


After video

After watching the video I have learned that physical change is when you take an object like paper do something with it like fold it or crumple it but it still stays the same because it is still paper, the form was changed but the substance stayed the same



Examples of physical change
Folding paper
Shredding paper
Turning paper into different shapes
Cutting vegetables/fruits
Grating things
Mixing things 

Melting an ice cube 

Tiger description



Royal,ferocious,regal,striped,unpredictable,tigers.  Large predators need to be able to sneak up on their prey, and the tiger's distinctive coat acts as camouflage, hiding them as they stalk prey in dense vegetation. No two tigers have the same stripes, enabling individuals to be identified by their unique pattern of stripes. Tigers use their body weight to knock prey to the ground and kill with a bite to the neck. They are also very good swimmers and have been known to drown their prey.  Tigers could spend days swimming; it is one of their most loved activities. They also like to roam free in their territories, who are very huge. They can spend entire days patrolling their territory. The White spots on the backs of their ears are sometimes thought to function as "eyes" to ward off potential attackers from the rear. Another theory is that they help tiger cubs follow their mothers through tall grass. Tigers have an average sense of smell, they have excellent night vision and they have pretty good hearing.

Christmas acrostic poem



Cookies are loudly being munched in cozy houses by a warm fireplace 
“Ho ho ho” Santa clause says merrily
Reindeer obediently lead Santa’s sleigh with pride, gliding it through the air to deliver presents to the children of the world
Icing is splattered precisely onto delectable gingerbread houses, by mothers who have worked hard to make succulent food.
Santa’s workshop is very busy for the elves make pleasurable presents to positive kids.
Tinsel is wrapped around the lush, tender, green trees that are covered with bright, colourful ornaments and decorations.  
Mrs clause is eagerly waiting for santa to arrive after delivering presents
A time of year to spend time with friends and family  

Santa delivers presents to those who are nice and coal to those who are mean

Catch it meerkats perspective



Intro-
I wake up from a relaxing sleep and stretch my limbs, ready for a new day My fellow meerkats and I slept huddled together in a pile to keep warm and cozy for the night.  Fortunately, I was at the top of the bundle so I could yawn, look around and slip away from the group to explore for a while. I poked my head up from my underground burrow to examine my surroundings. I looked left, right, then left again and spotted the other members of my gang peering at me from a nearby den entrance. My friends all spring out of the hole and together we scatter towards a tree and stare at a beautiful, red and juicy pomegranate. It hung down by its tough, brown stalk from a high tree branch. Me and my gang steadily climb up the tree. Then I go forward and stroke the pomegranate’s soft skin with pride and care. I admire its plump body. I quickly back out because of all my other mates who are waiting to admire it. After the last meerkat, we gathered on the ground and looked skyward, up at the magnificent specimen.  


Paragraph 2- 
Suddenly, a dark shadow loomed over us so we scampered to safety.  We then realised that this gloomy silhouette belonged to a merciless, menacing vulture.  He landed on a branch next to our beloved pomegranate and wrapped his long talons tightly around the tree limb.  He had a large, ebony coloured body with a wide wingspan. The vulture’s neck was covered in thick, white feathers and he had a scarlet coloured face.  His grotesque, hooked beak was the stuff of nightmares. He sounded like a grunting pig. Next, he shuffled along the branch and snatched the pomegranate with his sharp claws.  Then he flew away promptly into the distance…

Paragraph 3-
 Just then one of the meerkats raised their hands, signaling for a war to take place.  The other meerkats agreed and raised their hands as well. We chase that dense vulture who doesn’t know that we can easily catch up to him since we are way faster than him. One of the meerkats jumped onto the vultures feet and then I   jumped on . The other meerkats understood what we were doing and quickly they all jumped on

Paragraph 4- 
We continue flying at full speed. We can see so many trees and beautiful scenery.  “This is probably the best day of my life,” I said. 
I could see all the different trees in various shades of green they were luxurious and extraordinary. It was a wonderful sight. There were tons of pink and yellow flowers and the grass looked like it hadn't been cut for months.  The visibly vicious vulture suddenly shakes off and we all start to descend to the ground. Happily, the pomegranate falls down with us. One of my fellow meerkats, Mike the meerkat, caught the pomegranate and passed it around. My friends and I were to fast for Victor and he couldn’t catch the pomegranate or us. After a lot of catching and throwing, the vulture had sadly gotten hold of the pomegranate. We all land down to the ground safely. The vicious vulture was smirking at us and not looking at where he was going and crash!!!!!!. Thank goodness Mike, who is the best catcher in our group, Had zoomed off and caught the pomegranate.


Paragraph 6 -
 Once we catch the pomegranate then we form a triangle and start playing rugby with it. We are having so much fun tossing it around and passing it to each other. One of my fellow meerkats passes the pomegranate to me. Because  I am the leader I got to do the legendary shot…


Paragraph 7-

So much for the legendary shot, I think to this day because guess what happened. I was kicking the ball through two very tall trees and I guess nobody was there to catch it so... Splat!!.

Rainbow Water Density experiment

Rainbow Water Density Tower

Aim - To observe how substances with different densities interact

Materials
Glasses - 1 per group
Food colouring (red, blue, green and yellow - you can make purple and orange by combining two colours)
Sugar or Salt (and measuring spoon)
Measuring cup - 1 per colour (you can have 6 colours to work with, or limit it to 4 colours)
Measuring syringes 
Water (warm water from a tap or kettle)
Plastic spoons to mix the sugar and food colouring in the water
Pots of water to rinse syringes between each colour
Plastic plates or trays to protect the table from sticky sugar water


Steps (Method) we took to do the experiment:
 Put two spoons of sugar in the yellow dye. Put 6 in the red dye. Put 4 in the green dye. Finally,y put 8 in the blue dye. l  Get the blue dye and with the syringe collect 200mls. Squirt the blue dye into the glass. Now ow. collect 200ml of red dye. This time carefully,  get the syringe, go deep down and squirt. Now get 200mls of green dye. Again carefully squirt slowly. Do the exact same for the yellow. Wash the syringe every time before you add the next coloured dye. 


















Explanation 

All of the colours had different amounts of sugar, causing the colours to have different densities and refuse to mix together. Since it won’t mix, it instead makes a tower of all the colours from the first colour(the one with the most density) to the last colour laying on the top( the one with lesser density ).

Look at the websites below and also do research of your own - Then write a paragraph explaining ‘the science’ behind the experiment.  Why do we see the results that we did?
