HI my favorite blogger to day we are in science, and we are creating a ramp for a marble/pin Pon ball to see which would go the furthest.

Hypothesis

I think the marble is going to roll the further because it is lighter and I have seen how far it has gone before.

Plan

• we are planning to make the run way 4 meter long/ 4000 centimeters.
• we are going to use a file/blinder, ruler,cones,my Chromebook strap.

Steps

• We put down the file down like this
• 
• Then we set the rulers like this
• 
• Then we set the cones like this
• 
• Now we have to use the ramp 3 times
• The marble won 2/3 and the pin Pon ball won 1/3

Conclusion

It turns out that the marble won!, (yay)

both of the balls did not go the full lathe tho.

The marble went 1. 327.7  2. 285.9 3. 167.8 meters

The pin Pon ball went 1. 246.6 2. 232.1 3. 319.2 meters

Hope you enjoyed this blog post bye-bye 🙂

Paper Planes

16/2/24

Hi my lovely blogger, This is a quite detailed report but remember that all science experiments should be recorded in detail. The more detail and science, the more chance of hitting Legend. This report is at least a Pro level and at times a Legend but could use even more detail to really take it to the next level, I will be telling you all on what has been done about the paper planes from the start and to the need, Hope you enjoy and hope you enjoy you day.

Hypothesis (What I think will happen)

I think that the small plane will fly further because I added two more wings to make it farther.

Background

The first paper plane was made around 200 years ago.

The longest distance ever flown by a paper plane was 88.1 metres.

There are four forces that act on the paper plane when it is flying.

• Thrust, how fast it is pushed
• Lift, how much wing area can be pushed up
• Gravity, pulls the plane down
• Drag, slows the plane down

This video shows some information about how paper planes fly. I thought that it does a great job explaining how to make a great paper plane.

Equipment

• A4 paper
• A5 paper
• Chalk
• Metre stick

Steps (Method)

Here’s a video of me folding a paper plane

This is my idea: ( Mines better )

We then drew a line with chalk to mark the starting line. Then we took turns throwing the two planes and marking (or taking pictures) or which flew further.

We repeated the throw 3 times.

Results (What we found out)

The big plane flew further.

(Insert video or pictures here)

Conclusion (what it means)

The big/small plane flew further than the other plane.

Why I think that the big plane flew further because it has more strong built in it and its more able to handle the Strong wind.

I did some research and found out that planes with bigger wings fly further because they can generate more lift. Here is a Youtube video explaining why. Especially at 5.30 where he talks about bigger wings generating lift.

This website also has a great explanation about wing sizes and lift. It also talks about birds which is our teachers favourite thing so I’ll get extra points for adding this!

What I would change

I would probably make another plane so it will be more interesting and I would rather do it inside than outside because it was too windy.

Hypothesis

I think the small one will fly the farthest, because we added 2 extra wings

Steps

• find a video to follow to make a better plane.
•  put the camera on your chrome and start to video
• Though  and see how far it goes

Results

The small paper plane went the fastest

why?

because when we added the tow wings the wind will make it glide faster ,and it is lighter.
