The mysterious phone call

Zzzz ZZZz. It was the sound of my phone alarm I had already been awake for hours.

I checked my phone, there were 5 missed calls and a voice mall all from a unknown number. I sat on the side of my bed and picked up my phone, I hit listen to voicemail.

I heard a soft breathing, suddenly a cold breeze went down my back. I immediately ended the voice mall in fear.

My body slid down the bed and I dropped to my knees, my eyes started to sway, my head when heavy, I dropped to the ground. Ahhhhh, something pulled me under the bed. I felt myself sinking into the ground. It felt like I was being pulled through concert.

I screamed as load as I could but my family didn't hear me.

I felt myself stuck in place, I lifted my head to see myself floating in the air, there was pitch black all around me but there was a still strip of light. I started crying in stock. My body started to losin I was able to move I stood up. There were walls all around me, they were glossy and smooth like the drizzle of chocolate on a chocolate cake. I walked off into the distance, I touched the wall, It felt like sponge.

Suddenly my vision went black, I fell into a deep daze. My eyes started to open. I looked down, there was a was a body being covered up with a white sheet. A lady was bent over the body, she stood up. The lady had something that was under her feet. It looked like It was a type of costume. The lady reached down to the costume and pulled It over her body. She ripped it up, the rip went all the way up over her face. As soon as she finished putting the costume on the ripper disappeared.

The lady turned around to face me and then turned back, she creepily circled her head 180 degrees . Ahhhhhhhh. I screamed. She  was me!!!!

How might we......

How might we......

Yesterday LC7 listed down all problems in hpps school.

Once we did this we had to wirght up a poster on our main problem. My groups problem was based on Toliet problems. We thought of maney problems and then we wrote them down.

Info on how to make the rocket

Ballast can be any material that provides weight for the rocket and ensures the rocket can coast once it is launched.

Make sure you are in an open, outdoor area. The rocket will shoot up quite fast and high so remove any obstructions and warn anyone around you before you launch it.

Hold the rocket by the neck of the bottle and pump air into it. The rocket will go off when the cork can no longer withstand the pressure building up in the bottle.

Let go of the bottle. The water will shoot out everywhere when the bottle rocket takes off, so be prepared to get a bit wet.

Do not approach the rocket once you start pumping, even if it appears that nothing is happening with the launch, as this can lead to injury

Use scissors or a box cutter. You want a nice, clean cut so the bottles can be taped together cleanly and straight.

Cutting off the cap end of the bottle will make the rocket more aerodynamic

A rounded end is also softer so it will do less damage to any objects if the rocket hits something when it lands.To put in the kitty litter, tip the cut bottle a                       and pou   r in about                                                        ½ inch of kitty litter. Then, add enough water to wet the kitty litter completely. Add another ¼ inch of kitty litter and soak it again.                                                    Avoid                                                             dumping in too much kitty litter as this can create a dry layer of kitty litter than could get loose and scatter when the rocket is launched. Too much kitty litter, or                                                                                                              weight, in the rocket, can also cause the rocket to hit hard when it comes down.Then dry the inside walls of the bottle    

making the rocket for our project

Firstly we got a 2.25L bottle, we took the cap off because we didn't need it during this experiment. Then we used cardboard to cut out some wings, we had to make sure that the wings where even. Once they were even I duct

taped the wings on to the sides of the bottle making them level.

This should make the rocket go smoother, faster and higher.

project hypothesis

Hypothesis: We think the rocket will fly higher with the bottle filled half way with water because the more water that is  in the rocket the more pressure is on the air inside. We don’t want to fill it right up with water because water is denser than air, making it heavier. The more pressure  on the air, the more it floods out of the bottle, the higher it will go.

Project 2 and end

Decreasing air pressure

Air pressure decreases as we move upward. Your ears will often pop if you are traveling in the mountains as you go uphill and downhill in a car or train. Your ears are adjusting to the pressure in your eardrums when they pop. This equalizes the pressure in your ears so they will not burst when the pressure increases or decreases.

The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth.

Atmospheric pressure is commonly measured with a barometer. In a barometer, a column of mercury in a glass tube rises or falls as the weight of the atmosphere changes. Meteorologists describe the atmospheric pressure by how high the mercury rises.

An atmosphere (atm) is a unit of measurement equal to the average air pressure at sea level at a temperature of 15 degrees Celsius (59 degrees Fahrenheit). One atmosphere is 1,013 millibars, or 760 millimeters (29.92 inches) of mercury.

Atmospheric pressure drops as altitude increases. The atmospheric pressure on Denali, Alaska, is about half that of Honolulu, Hawai'i. Honolulu is a city at sea level. Denali, also known as Mount McKinley, is the highest peak in North America.

As the pressure decreases, the amount of oxygen available to breathe also decreases. At very high altitudes, atmospheric pressure and available oxygen get so low that people can become sick and even die.

Mountain climbers use bottled oxygen when they ascend very high peaks. They also take time to get used to the altitude because quickly moving from higher pressure to lower pressure can cause decompression sickness. Decompression sickness, also called "the bends", is also a problem for scuba divers who come to the surface too quickly.

Aircraft create artificial pressure in the cabin so passengers remain comfortable while flying

Atmospheric pressure is an indicator of weather. When a low-pressure system moves into an area, it usually leads to cloudiness, wind, and precipitation. High-pressure systems usually lead to fair, calm weather.

Project research 2 and a half

What is air pressure

What is air pressure? Air pressure is the weight of air molecules pressing down on the Earth. The pressure of the air molecules changes as you move upward from sea level into the atmosphere. The highest pressure is at sea level where the density of the air molecules is the greatest.

Measuring air pressure on island of Hawaii. Left picture taken at 14,000 ft at Mauna Kea observatory when the bottle was sealed. Middle picture of the sealed bottle at 9000 ft. Last picture taken at 1000 feet where the bottle was crushed.

WHAT IS AIR PRESSURE

Sea level air pressure

The greatest air pressure pressing down on our bodies is at sea level. Scientists use the term one atmosphere to describe the pressure at sea level. Normal pressure at sea level is 14.7 psi (pounds per square inch). Normal pressure at sea level measures 29.9213 inches (760 mm) on barometers. This means that on every square inch of our body and

At sea level on the surface of the Earth there is almost a ton of pressure pressing on every square inch of our body. The reason we are able to move our hands back and forth is because the pressure is equal on all parts of our hands. Our bodies are not crushed by the weight of the pressure because there is equal pressure inside and out of our bodies also.

How is Term three going

Term three is doing way better than last term already. I am doing way better at maths buddy and I'm getting all of my follow ups done. I am still talking to Friends, so I'm going to find a space that I'm not distracted in. I have all ready noticed that I feel way better when i know i have all of my follow ups done. Plus its way less stressing when you don't have lots of follow ups that you know aren't done. This term the teachers have stet a goal for all the students. The goal is on doing the right thing when know one is watching. I think think that this goal is very important for me.Because for me this is very hard to do. So over all i think that term three is going pretty well but i can improve.

Project statice

Lola and I are working on a project about rockets we want to find out if we change how high a toy rocket flies with Air pressure. Are goals are to first find what air pressure is then make our own bottle rocket from scratch. We've  looked at lots of different websites to see what methods do and don't work. We will be testing the rocket several times and we will change the air pressure on every test.

That's all we have for now but i will inform you when we are further ahead.
