confusing

 have you ever wondered why all together is spelt separate but separate is spelled together, take a moment to ponder why they are spelt like that its, weird and unusual isn't. people also say your not perfect but your perfect at not being perfect, okay now i'm just confusing my self.  have you notice that zoo's are paying you to look at stolen property because nobody owns those animals. did you notice that the centre of gravity is v and v is pointing down. your a murderer did you know that you've murder trillions of bacteria in the shower. go lay in an open field and that technically make the world your backpack.

Gravity 

Read, then answer:

Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.

1.  What keeps all of the planets in orbit around the sun? The force of gravity

What else does gravity do?

Why do you land on the ground when you jump up instead of floating off into space? Why do things fall down when you throw them or drop them? The an\wer is gravity: an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall.

2.  Define gravity in one sentence? An invisible force that pulls objects together

Anything that has mass also has gravity. Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is.

3. What makes gravity weaker? distance

Earth's gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That's what gives you weight. And if you were on a planet with less mass than Earth, you would weigh less than you do here.

4. What does Earth’s gravity come from? mass

5. Look at the image below and write how much you’d weigh on the following planets if you weighed 100lbs on Earth.

Jupiter 253 lbs           Mars 38 lbs      Venus 91 lbs

Saturn 107 lbs              Neptune 114 lbs

6. How much would you weigh on the moon?  17 lbs

You exert the same gravitational force on Earth that it does on you. But because Earth is so much more massive than you, your force doesn’t really have an effect on our planet.

7. Why doesn’t your force really have much effect on Earth? Earth is much more massive than humans

Gravity in our universe

Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides. Gravity creates stars and planets by pulling together the material from which they are made.

8. What causes ocean tides? Gravitational pull of the moon pulling the seas towards it. 

9.  How does gravity create stars and planets? Pushing material together

Gravity not only pulls on mass but also on light. Albert Einstein discovered this principle. If you shine a flashlight upwards, the light will grow imperceptibly redder as gravity pulls it. You can't see the change with your eyes, but scientists can measure it.

Black holes pack so much mass into such a small volume that their gravity is strong enough to keep anything, even light, from escaping.

10. Why is gravity in black holes so strong that it keeps anything (even light) from escaping? Because nothing can escape black holes

What is a black hole?

a dead star

Gravity on Earth

Gravity is very important to us. We could not live on Earth without it. The sun's gravity keeps Earth in orbit around it, keeping us at a comfortable distance to enjoy the sun's light and warmth. It holds down our atmosphere and the air we need to breathe. Gravity is what holds our world together.

11. What is the role of the sun’s gravity? Keep it away from us

12.   Can humans live without gravity? no

However, gravity isn’t the same everywhere on Earth. Gravity is slightly stronger over places with more mass underground than over places with less mass. NASA uses two spacecraft to measure these variations in Earth’s gravity. These spacecraft are part of the Gravity Recovery and Climate Experiment (GRACE) mission.

13. Describe where Gravity in Earth is slightly stronger. The core

The GRACE mission helps scientists to create maps of gravity variations on Earth. Areas in blue have slightly weaker gravity and areas in red have slightly stronger gravity. Image credit: NASA/University of Texas Center for Space Research

GRACE detects tiny changes in gravity over time. These changes have revealed important details about our planet. For example, GRACE monitors changes in sea level and can detect changes in Earth’s crust brought on by earthquakes.

14. List 2 things that the GRACE mission can do for Earth.

i) detects tiny changes in gravity

ii) reveal important details about planets

 15.  Gravity on Mars

List 5 or more facts about GRAVITY ON MARS in the space below. You can copy and paste and add images. Save in your Hurumanu 3 File.

Its not heavy

You can almost fly

You feel lighter

Your faster

You move your body faster

The white feather

The white feather

The invader thought they were teaching you a lesson but really they were causing mass depression.

All of you were harmed but they were armed.

Nobody was lending you a hand when people were taking your land.

What they did was sad and made you really mad.

Gold Poem

here is my poem about gold hope you like it and give me feedback in the comments

Gold is expensive

Gold was rare

Gold can make you be rich

Gold feels hard

Gold looks shiny

Gold buys money

Gold makes fake friends

Gold  often is expensive

Gold comes in veins

Gold always is heavy

Gold brings money

Gold gives extra weight

Gold has been in New Zealand

Gold will always be rare

Gold provides money

Acrostic Poem

Old

Loud when it hits the ground

Delightful

Rare

Uncommon

Maslow's hierarchy of needs

Maslow's hierarchy of needs is a motivational theory in psychology comprising a five-tier model of humans needs, often depicted as hierarchical levels within a pyramid.

Needs lower down in the hierarchy must be satisfied before individuals can attend to needs higher up. From the bottom of the hierarchy upwards, the needs are: physiological, safety, love and belonging, esteem, and self-actualization.

You will need the bottom to get to the top.

fitness results

this term in PE we have been doing PE activities and getting our results my results are

vertical jump: 2.0 when i'm just standing when i jump i get to 2.3

beep test: i got to level five and my heart beats in 30 seconds is 198

I am happy with my beep test level

I think i could get better at the beep test by running more
