1. Cut cardboard to be a circle.

2. Cut a circle in the middle of the cardboard.

3. Paper mache a balloon.

4. Glue the paper mache balloon to the cardboard.

5. Pain the UFO.

How to make UFO

Results:

Discussion:

Have there been any sightings of UFOs?

Unidentified flying object (UFO), also called flying saucer, that name is used when referring to an unidentified object in the air.

The first well-known UFO sighting occurred in 1947, when businessman Kenneth Arnold claimed to see a group of nine high-speed objects near Mount Rainier in Washington while flying his small plane. 

Conclusion:

Did it work? 

Yes, our making of our UFO worked.

Is there anything you would do differently?

Maybe be more efficient when making the UFO, so that we could finish it earlier.

Eclipse - Science

 Solar and lunar eclipse

How do they occur? 

    - Solar eclipse occurs when the moon gets between the sun and earth.

    - A lunar eclipse appears when the moon passes through the earths shadow.

What do we see?

    - When a solar eclipse occurs we see darkness in the middle of the day.

    - We see the moon disappear in the night.

When was the last solar eclipse?

    -  1965.

When was the last lunar eclipse?

    - 2019

When is the next solar eclipse?

    - 2028

When is the next lunar eclipse?

    - 19 November 2021.

Volcanoes - Science

Mount Tongariro

Where is it?

Mount Tongariro is a volcano that is located in the North island behind lake Taupo.

Whats special about it?

You can actually hike up to the top of the volcano it is a 19km hike.

It has also erupted 70 times since 1839 and only has 12 cones to it.

When did it last erupt? What was the damage?

It last erupted not to long ago in 21 November 2012, no one  got injured but a building did get damaged which was the Deparatment of conversation Ketetahi hut.

What are local stories/myths to this volcano?

Tongariro is traditionally the belly of the fish that Maui  caught and there are many Maori legends concerning the  mountain.

Trolley dilemma - English

 What would you do in the trolley problem?

• Well either way you're going to get blamed for killing someone, because if you kill the five people and don’t make the shift people are going to wonder why you would’ve rather killed five people rather than one. But if you make the shift to kill just the one person you would probably get more sincerity from the people you would’ve had to explain why you did it. 

• But you could just say you did it to save five lives instead of saving one person even though you had the option to save five lives, but you had to explain to 5 peoples families and a lot of the world for your reasoning to just be willing to kill the five people, even though it was all under your control even if you just tried to ignore it.

Wind racer - Science

Aim:To make a wind racer.

Research:

Youtube

Equipment:

-Trolley

-Bamboo/metal rod

-Cardboard

-Newspaper

-Tape

-String

-Plastic Bag

-Popsicle Sticks

Method:

1.Put the metal rod in the trolley.

2.Cut pieces of material into squares.

3.Draw on the paper for creativity.

4.Gather and cut pieces of tape and string.

5.Stick the materials to the metal rod.

Result:

Discussion: The four forces acting on the wind racer were:

Gravity - The gravity helped to keep it down on the ground instead of it flying in the sky, and then the wind made it than fall over.

Support - Support helped it by the ground keeping the wind racer up instead of it going down straight away.

Pull - The wind racer stopped when it couldn't get pushed any longer.

Push - The leaf blower pushed the wind racer forward or eventually for it to tip over.

Conclusion:

The wind racer did eventually work properly, but at first we had the leaf blower to close to the wind racer which caused the push to be to strong the wind racer couldn't handle it. But then we tried again and it did work because we moved back more and it moved forward.

Why did it slow down?

The wind racer slowed down because the leaf blower was too far away so the wind coming out of it didn’t reach it and the pull caused it to stop as it couldn't get pushed anymore, so that would mean the pull was bigger than the push.

What would you do differently?

Make the wind racer better in terms of Structure, design and wind resistance. I would also use the leaf blower better and put the wind racer further away from the garden so it doesn't full in.

Fire extinguisher test - Science

 Aim: To show that carbon dioxide gas is produced when a metal carbonate reacts with acid.

Method:

1. Add a pea sized amount of the metal carbonate into one of the boiling tubes.

2. Place this boiling tube into a test tube rack. Ensure you have the bung and delivery tube ready.

3. Add 5 ml of acid to the boiling tube and quickly insert the bung and delivery tube into the mouth of the boiling tube.

4. Holding the other boiling tube with your tongs, capture the gas produce in the other test tube.

5. Wait about 1 minute so the tube will be full and then get your partner to light the wooden splint.

6. When the test tube is full of gas, then carefully remove the tube from underneath the delivery tube.

7. Then carefully place the burning splint into the test tube.

Result: This experiment lead to the gas we made by adding hydrochloric acid and sodium carbonate to produce sodium chloride + oxygen + water, this gas cause it to put the lit splint out.

Discussion: We used hydrochloric acid + sodium carbonate = Sodium chloride + oxygen + sodium chloride to create this gas.

Conclusion: It did work it was to show what gas puts out fires like a fire extinguisher uses the same type of gases we used to put out the flame on the splint.

Water pollution - Social studies

In social studies the last couple weeks we've been watching videos and researching information about world wide problems including the great pacific garbage patch and sea problems/pollution etc, and also how one guy got inspired to try help.

The great pacific garbage patch is a massive patch of garbage it ranges from North America all the way to Japan. The great pacific garbage patch is made of plastic debris which is basically plastic things that get dumped or swept into the ocean.

Their was also a guy called Ali who got inspired to start being more sustainable in his life and try help with all these sea problems. He got inspired because he had realised how much it was effecting our planet and especially our sea life which also effects us.
