Kia ora, I am here with another blog post about soundwaves.
The lower the water the higher the pitch and the higher the water goes the lower it gets.
Anei nga kirata mo te Soundwave.
Today we are learning about DNA in Science and we are using lollies and toothpicks to make a DNA Lolly
The full DNA process is 21km and the lolly is 7cm
7cmx3000000000=2100000000 and ÷ 100000 =210000km
My hypothesis is that the marble will go further because it has more rolling techniques and it also has more weight. That is my hypothesis.
Rolling each ball down, roll it three times and measure the distance between each ball and the end of the ramp using, my feet,a ruler,a tyrannosaurus rex tooth,chromebook, an anaconda skin.
| Roll | Marble | Ping Pong Ball |
| 1 | 10 | 3 |
| 2 | 10 | 5 |
| 3 | 10 | 10 |
| Average | 10 | 6 |
The hypothesis was correct because the marble went further and went out the door.
I think that the small plane will fly further because the wings will make the wind.
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.
Here’s a video of folding the paper planes.
The big plane flew further. 2 times out of 3.
My hypothesis was incorrect because the wings on the big plane were not folded enough.
