Egg Drop Experiment

We were learning about Inertia, part of Newton's first law of motion. This law basically means when an object is at rest it doesn't want to move and when the object is moving it does not want to stop. The equipment we used was: 1 cup, Water, A flat tray or plate, 1 egg and 1 cardboard toilet roll. 

What we did was fill the cup with water then place the plate on top, then balance the toilet roll on it's end on the plate. We then put the egg on the toilet roll length ways and tried to hit the plate out from under it so that the egg fell into the cup of water.   

The science behind this experiment was about, Newton's First Law, once the egg was moving, it didn't want to stop. The container of water interrupted the egg's fall, providing a safe place for the egg to stop moving so you could recover it unbroken. The gravity-pushed egg caused the water to splash out. 

I found it easy to hit the plate and toilet roll out from underneath the egg because all you had to do was give the the plate a short sharp tap and it shot out from under the egg. My partner Olivia gave both our eggs little cracks then later on I enlarged them, causing the yolk and egg whites to spill out. Nothing was really hard to do.

Next time I will not hesitate before I hit the plate because the times I did that the egg broke and created a rather large mess evolving a lot of water and some egg whites and yolks.  

M&M Stacking

We were learning about M&M stacking. The world record for M&M stacking is five, a British engineer got five and one of the Maori all blacks got five. The record for M&M stacking in the science elective is three. Vinny got three and Tyran got three. Before we did M&M stacking we stacked pebbles, the most I got there was five.

I found it easy to get two stacks of two but that was the most I got apart from one stack of three that lasted about two seconds. I figured out that the red and the orange M&Ms stuck well together with the Ms facing each other. 

It sounds like it would be easy to stack M&Ms but it is actually really hard. It is kind of like trying to stack sticky soccer balls. I could get two stacks of two but as soon as I tried to add one more to the stack it toppled over. 

Next time I will try to find the center of the M&Ms gravity so that it will balance better.

Flood Inquiry

We were learning about the three main floods that happened in New Zealand (The Tolaga bay, Kopuawhara and Southland floods). My personal favorite was the Tolaga bay one because it was the most recent one, I liked the the Kopuawhara one too though. This blog post is about the must do activity.

I found it hard to finish to my usual standard because like my create I was absent for the first day we did this. I soon caught up though by doing some of my work at home after school.  

I found it easy to answer the questions because of all the information that was put on this slide. The questions were the same as all the ones I've done before so I got them completed quickly. 

Next time I will try to put more detail into my answers so the reader is more highly entertained. This will be a goal that will be easy to complete. 

Create Emergency Kit

We were learning about the three main floods that happened in New Zealand (The Tolaga bay, Kopuawhara and Southland floods). My personal favorite was the Tolaga bay one because it was the most recent one. This blog post was the create activity, we had to make a emergency kit in case of a flood.

I found it hard to finish to my usual standard because I was absent for the first day we did this. I soon caught up though by doing some of my work at home after school. 

I found it easy to create my emergency kit because I had done something similar for reading. I used the same bag and radio but the others I used I polylined myself especially for this activity. 

Next time I will try and add more things to my emergency kit that you only need for floods. The thing I did this time had objects that could be used for all different types of natural disasters.
