Six second science video

Over the last couple of weeks I have been making a six second sience video here it is:

Ninja Pig

NINJA PIG

Introduction

The new animal, Ninja Pig has formed  and did you know that he can do a triple back flip kick? Ninja Pig is Spider Pig’s brother ( the Movie star off the Simpsons), so don’t mess with Ninja Pig!!!

Ninja Pig is made out of a Ninja and a Pig, When you put them together it makes, Ninja Pig. Ninja Pig comes from a galaxy way up in space. He sleeps at day and  karate chops at night. If you come across  ninja pig he will karate chop your head off and backwards kick your arms off for his midnight snack.

Ninja Pig is not afraid of anything except for light, so always take a torch when you go out at night. This creature is rare but will strike without warning so next time you go out at night remember a light or Ninja Pig with strike. He approaches without a sign and is as heavy as a full bottle of wine.

  

Ninja pig is round and has a black suit with red flames around the outside of his suit. The flamed suit is indestructible and he carries his machete and Ak47 on his belt, he uses them to kill his enemies. If you see him put his hand in his mouth, you’re dead! It is special poison that only ninja pigs can survive you will die instantly.

Ninja Pig’s main diet is humans, but when he gets sick of human flesh he moves onto takeaways. You might see him at Carls Junior, McDonald's, Burger king, Mac's fish & chips, KFC and his favourite is Westermans.

When he catches you he kills you and takes the blood, eye balls and testicals out and freezes them for an ice block. Next time you go out and about be sure to watch out for Ninja Pig.

Centripetal Force

Hypothesis:

I predict that the faster you go the lighter it will get and the less water will spill. the water will stay at the side on the side at the back. If you spin it fast enough it he gravity should not harm the water.

Variables we must control:

Variables	Control
liquid	each bucket filled to the 2 mark to ensure they have the same amount of water.
direction	spin the same direction.
object	make sure they are bothe the same size.
weight	to make sure the object weighs the same.
technique	so they start the same and finish the same. everybody holds it on the same angle.

Method:

You hold the bucket exactly on the same angle and spin around holden the bucket inwards haveing a look aat the water. You have to try and keep as much water as you can in your bucket. All you need is a bucket and water.

Results:

Was your prediction correct? I was correct  except for when I thought it would go to the back but it just stayed still. What happened and why?The centripetal force kept it still inside the bucket. The faster you spun the lighter it went the more it wanted to fall out and the gravity made it hard to start to lift the bucket at the start.

Yay I am doing it

Boat or Submarine

 Boat or Submarine  

Scientists:

Question/Goal/ problem

What shape of container will hold the most weight ?

Hypothesis ** Our shape is like a long rectangle and we think it will be good because it is quite wide because it will carry more coins.

Materials

Container filled with water, modelling clay, old coins

Method Create a boat out of modelling clay.

I Fill the container with water.

Place the boat carefully onto the water so it floats.

One at a time , put coins carefully into the boat . Count how many coins are in the boat before it sinks.

Observation/ Analyse (What happened and why I think it happened)

**Our shape held 6 coins  but then it sunk because it wasn't big enough and it was a bit too thick and it was to heavy

Conclusion

I think the wider the better and the thinner the better.

The pefect boat (Just about.)

Ballon Rocket

Balloon rocket

Hypothesis:

It will fly like a rocket

Materials

balloon, tape, 2 stable objects, string

Observation

It went flying across the nylon and it moved all the air out the small gap to push all the air out and it moved like a rocket.

Conclusion

The air from the back of the balloon pushes against the stable objects.

Does Air have Weight?

AIR HAS WEIGHT

Did you Think air has weight?

My prediction: NO because it floats.

While I am going to tell you, yes it does it has about 15 pounds of weight in the air. If you were like me and thought it didn’t you are wrong.  

Equipment:

ruler (maybe two)

 straight newspaper

and a firm karate chop

Here is my explanation:  

you put the ruler half on a table and scrunch a piece a paper when you karate chop the ruler and the paper up because their was air under it. When you lay the paper flat no air is under so it will snap the ruler (hopefully.) When you just have a ruler halfway on the table it flings a bit like something in a catapult.

Woah Crighton you  have three arms!!!

Did I break it?

Race a speed boat

Race a Speedboat

Can you make a paper boat race across the water just by gently touching the surface of the water?

Hypothesis

when you touch the dish washing liquid it water it will bubble and make the boat move.

Materials

Coloured card, washing up liquid, pencil or sharpie, scissors, large container of water.

Method

we cut out a shape for our boat then we filled our bucket so it was a quarter fill. Then we but our boat in the water and put a touch of dish washing liquid on our finger and we slowly put it in and we broke the surface tension to  move the boat.

Observation

We put our hand in and broke the surface tension to  move the boat. broke the surface tension to  move the boat.

Conclusion  

We broke the surface tension to make the boat move. The water that didn't break pulled the boat

Short Experiment to Follow Up

Make Metal Float

Gently place a paperclip on the water’s surface.

Hypothesis  

It does float because you carefully remove your hand and it will float but if you don't it will sink.

Observation

It does float because you carefully remove your hand and it will float but if you don't it will sink.

Conclusion  

When Henry removed his hand it broke the surface of the water.
