Hover Ball

Hovering Ping Pong Ball.

Is a hair dryers force is strong enough to keep a ball in the air? To test this experiment supplies are needed, how to set up and what to do is the most important thing to know, observing and giving answers to any hypothesis will help to find the answer to this question, finally why this happened and other experiments that you could try out.

Supplies Needed:

Ping Pong ball

Hair dryer

Plug the hair dryer into the wall and point the fan upwards. Place the ping pong ball on the fan of the hair dryer or you could put it on when it’s going either way it works. Turn the hair dryer on and watch the ball hover in the air.

When observing, very noticeable things popped up like when the hair dryer is going and the ball is thrown in it seems to bounce back and start balancing in the middle of the fan. If it starts on the fan and the Hair dryer is turned on the ball starts to slowly pull itself up so it’s not so close to the fan. Would it work with a solid ball and not a hollow one?

The key to this experiment is the force of the hair dryer. When it is pointing up the ball is able to balance if it is pointing in any different direction the experiment should fail. The hair dryer is strong enough to hold a ping pong ball but isn’t as strong as gravity when it comes to heavier kinds like a tennis ball or a cricket ball.

Other Experiments:

Try it with two hair dryers, put one facing up and one facing down causing the ball to stay in the middle of the two. Or point the two hairdryers at each other and see if it stays up then. If you are too advanced try and balance two ping pong balls on one hair dryers.

Heated Air

Heated Air

What  happens when air heats up? Think of an experiment and test it to see if the answer pops up. There are 4 paragraphs giving clues to answer this question , paragraph 1 will be about the supplies needed, 2 is explaining what to do when ready, 3 is a paragraph about observing and giving answers to any hypotheses brewing in the mind, 4 will reveal all the secrets, how it all happened and what caused it.

To carry on with the experiment, supplies will be needed:

1. tub full of hot water

2. a tub full of lukewarm or room temperature water

3. 2 fizzy bottles

4. 2 balloons.

Place the two tubs outside incase of any spillage. Wrap the mouth of balloon over the mouth of the fizzy bottle. Do this with the leftover balloon and bottle. Make sure the balloons are tight so no air escapes. The experiment can now start!

Immerse both bottles into separate crates. Something very noticeable will have popped up, the lukewarm water does nothing to affect the balloon. As for the other bottle that was forced into the hot water would have made the balloon blow up without using a pump or a human mouth. There is no trick, swap the bottles around to see if it does the same thing. The bottle that was once in the hot water is now in the lukewarm water. This made the balloon deflate. Same for the other bottle that was once deflated will now be slowly inflating.

By observing, there should be an idea of what happens when air heats up inside a bottle. If it still continues to circle the mind then try it once more. The balloon doesn’t seem to blow up as much as before. This is because the hot water would have by now cooled down. How does this affect it? The key is how hot the water needs to be.

When the bottle is immersed in the hot water it makes the balloon inflate by itself. The reason for that is the air inside the bottle is trapped when you put the bottle in hot water the particles expand which causes movement. The only place they can go when they are expanding is in the balloon because it is flexible material. That is why the balloon blows up. Why doesn’t the room temperature water make the balloon blow up? It is because the water isn’t hot enough so the balloon stays in a state of inertia. What happens when air heats up? The particles expand causing the balloon to blow up.

Locky

When I walk in the lounge and all the lights are out I suddenly see two shiny black dots move around the room.They’re moving everywhere almost unable to be catched. I realised that I have seen these before. It's Lockys beady eyes. He rubs his head against my leg as a sign of he wants the light on. I flick the switch and turn around to see Locky rolling around on the floor. His black and white curls seem like he has been coughed on by the fire and ashes have gone everywhere. His wagging tail shows me that he is happy to see me and wants a pat. I look at his long curls that droop to the floor and wonder if it’s time to get a haircut. I only came out to get a drink of water so I turn off the light and everything becomes complete darkness once again. I see the beady eyes following me back to the bedroom. He quickly and quietly sneaks past me and claims half the bed all to himself.

Throughout the night I can feel his ears twitching. He tries to wipe his drool on my arm but seems to get the blankets instead. The only thing that gets me was the rebound of his scaley tongue trying to climb back into his mouth.

I rose out of the bed the next morning and stretch my arms out as far as they go. Locky is already up, probably in the kitchen waiting for someone to stack his bowl full of dog biscuits. I walk towards the door, suddenly he pounces out from under the bed. His back is arched and and his paws are flat on the ground. It seems like he is trying to tease me into playing with him. I grab his chewed up tennis ball and throw it out the back door. He picks up his body and scrambles to get outside. Within a second he his crouching by my feet again. I decide to pat him instead, his curls have a chalk feeling to them but thats just the weekly knots. He jumps up with his paws pressed against my legs. They feel as soft as a feather pillow. He rolls over and you can the bald patch around his stomach. His belly started jumping up and down like a vibrating toothbrush.

He gets very impatient and starts barking like a huge threatening guard dog. He is no where near the size of a guard dog though. He turns to the side and pulls his body up off the ground. The whimpering starts. It carries on for as long as you can tolerate it. The untuned horn noise seems to get louder and louder. Angrily, I turn around and pet him. He start to breath heavily as a sign of him getting his way.

Gravity VS. My Force

Tuesday 15th our class decided to step up to gravity and see who could keep their arms up for the longest. It didn't take long, half the class had given up within 3 minutes. As for Thea, Phoenix and I we were on fire. Literally we had been holding up our arms for so long that it started to burn. To stay in the competition we had to keep our arms up above our shoulder length, they warn’t allowed to bend and finally our fingers had to be straight. Time went by and the pain seemed to spread. We started 11:50 and us 3 finished as a draw at 12:40. It was such a relief to finally put my arms down. The pain lasted throughout the day but it was all worth it. I think this was a great way to show how powerful gravity is and how no one is able to defeat it. At first I thought it was a fun activity then it turned into an extremely hard competition. In the photo below I am trying to do my work as well as keeping in the competition.

Flexability

Monday The 14 our class tested ourselves and how flexible we are. To test how flexible we are, we created our own equipment that included a plastic box and a piece of wood, longer than 60 centimes. You place the piece of wood on top and draw the measurements. 30 centimeters on the negative side and 30 centimeters on the positive side. For our first try I got 11 centimeters on the positive side of the ruler. I tested my flexible skills with Poppy, Thea, Daniel and Charlotte. The highest mark was Thea's, she got 18 centimeters positive on Monday. On Friday we will be trying this to see if we improve our flexibility skills. Every day in between we did hamstring and lower back stretches to try and get a better mark. I have improved by 1.5 centimeters. Others improved by 5 centimeters or more! Only a few decreased.

Monday	11cm
Friday	12.5cm

Sailing

Words: sailing, starboard, catastrophe

The wind blew heavily and the glass shattered. Henry and Sam decided the best place to be when a storm was brewing was out in the open. The only place that seemed safe was the lake. The boys had no knowledge of what to do or how to sail a boat but they had seen many T.V shows about it. They went with their gut and got on the boat . They sat there for awhile because they didn’t know you had to row to get the boat to move there was always a motor that made the boat move. Without knowing they still sat there waiting for the boat to start and it did finally not the way they had planned but it started alright. The tides of the lake became bigger and bigger drifting them into the middle of the lake. The boys panicked, the storm was getting worse and the boys thought that they needed to lighten the load so they threw the paddles overboard. The weight of the boat didn’t make a difference so they sat there asking themselves why they threw the paddles overboard, starboard and not portside.

An hour went past and the storm was still going, not as bad as before but there was heavy rain and shrieks of thunder now and then.  The boys sat on either side of the boat mocking each other and blaming each other for the whole thing. With no way to get back to shore they had nothing to do. Henry finally decided to break the fight say that it was no ones fault it was just a bunch of bad luck! “No, it is way more than that it is a catastrophe!” The day passed with the boys listing what it was. Whatever it was.

Darkness started to appear the boys shivered with fear and because they were cold. They couldn’t help but to say sorry. Saying sorry wasn’t going to take them back to shore though and they both knew that. They snuggled next to each and drifted off to sleep dreaming of happy places. In the time that they slept another storm brewed and left only this time it floated them back to shore.

In the morning Henry thanked sam for sailing them back to shore and Sam took full responsibility for it but he knew he didn’t do it. His thoughts were  that Henry was just saying that so Sam would be as cool as him but Henry didn’t do it either. No one thanked the storm.

Bears

Bears

2. What is your favorite bear?  Milly

3. Have you touched a bear before? -sam

1. What encouraged you to start liking bears?- Heith.

4. Bears are often found in myths and many cultures connect with them spiritually.  Why do you think this is?  Mrs Roil.

There are many different species of bear, this includes the Brown bear, Asian black bear, Sun bear, Giant panda, Spectacled bear, Indian sloth bear, and finally the Polar bear. The atlas bear is one of the subspecies of the brown bear, which is the only bear native to Africa. Sadly the Atlas bear has been extinct since the 1870s. The most widespread species is the brown bear, which comes from Western Europe eastwards through Asia to the western areas of North America. The American black bear is restricted to North America, and the polar bear is restricted to the Arctic Sea. All the remaining species are Asian.

Ever since I was little girl I tried forcing my mum to buy me a bear, she took it the wrong way and brought me a stuffed toy. I always said we could keep a real bear in the shed with a dog bowl of water. She refused.  I first started liking bears when I was 1 and a half when my grandad started hunting. He read me heaps of stories about bears in America and how he was going to travel there and be the first of his friends to kill one. When I was little I was convinced that a grizzly bear was the only bear in the world. I found out not long after that there are other bears and I then decided that sun bears are my favourite. I like the very long tongue that sunbears use, and how they stand on their back legs to look around.  I was lucky enough to feed a sun bear at the Wellington zoo. The zookeeper said when sun bears are tired they are very restless.

Because of their spirit-like appearance, spirit bears hold a place in the oral stories Scientists have found that black bears are not as effective at catching fish as white bears, as the white bears are less visible from the perspective of the fish. While at night the two colours of bears have similar success rates at catching fish, such as salmon, during the day the white bears are 30% more effective. Which is why the white kermode bear is most known as the spirit bear.

The Kermode bear was named after Francis Kermode, former director of the Royal B.C. Museum, who researched the subspecies and a colleague of William Hornaday, the zoologist who described it.
