Simple machines

 Did you know that there are the simple machines that help people build and work more easier. These are three simillar simple machines, The wheel and axels, Pulley's, and Screw. 

Six simple machines

These are the six simple machines that we found around our eniorment the six simple machines are the screw, inclined plane, wedge, wheel and axle, pully, and the lever. 

The lever helps lift heavy objects move from a low level to a high level. 

The inclined plane is used to move objects from a low level to a high level. 

The wedge is used to push things apart. It changes the directions of force to go sideways. 

The wheel and axle is used to move objects around easier.

The pulley is used to move heavy objects from a low level to a high level. 

The screw is used to push objects together.

Simple Machines

 Simple machines are used to move heavy objects, carry objects, and attach objects together. 

There are six simple machines;

One of the simple machines is a wheel and axle is used to move objects around easier it redues the amount of force needed to push by making something roll. 

Another simple machine is a pulley, a pulley is used to move heavy objects from a low level to a high level it reduces the amount of force needed to lift heavy obejects by sharing and dividing the force out. 

The third simple machine is a wedge the wedge is used to push things apart. It changes the directions of the force to go sideways. 

The fourth simple machine is a screw a screw is used to attach objects to other objects. This machine works by making objects twist around the machine. 

The fifth simple machine is the lever the lever is used to lift heavy obejects it changes the imput force by using a pivot and a bar. This machine can also be used to mesure forces like  weight.

The last simple machine is aattach inclined plane the inclined plane is used to move objects from a low level to a high level more easily. 

These are all still used today to move objects.

LS1's Learning Treaty

LS1 learnt about the 3 Ps in the Treaty if Waitangi and how they apply to our learning. 

First Mr Ogilvie introduced the 3 Ps in the Treaty of Waitangi. 

Then in groups we wrote statements about the 3 Ps in LS1. 

LS1 figured out the 3 Ps are all connected. After that we used our group ideas and thought about how they connected to me. 

I chose these three statements because they will help other people and help me listen to other peoples ideas and learn from other people. 

Emergency shelters

 Emergency shelters are protection against natural disasters such as a storm or an earthquake. 

The Protectors requested aluminium foil, hard plastic, metal poles, clay,  chicken wire, and plaster of Paris. 

The aluminium foil is for the inside of the shelter, the foil is used because it is a good insulator and heat reflector. 

The hard plastic is for the windows, the hard plastic is used because it’s easier to shape than glass.

The metal poles are for stabilisation, it was used because it is a heat reflector insulator.

The clay is used to form most of the shelter, it was used because it is tough, so if the shelter topples over then the poles will not easily break off.

The plaster of Paris and the chicken wire is used for a similar purpose as the aluminium foil, they were used because they were used to hold the clay.

The tin can is used for the door, the front and the back of the shelter. The purpose of this shelter was to protect against bush fires. 

Emergency shelters are used worldwide and are very important. There are a lot of steps you need to do to build an emergency shelter.

Emergency shelters

 During this week's inquiry session, we were learning how to design an emergency shelter. 

First, we designed a quick sketch of an emergency shelter on a piece of paper. We had to draw our design from a front angle and a side angle. We also had to think about what shape would be suitable for natural disasters such as strong winds. We used an octagon because if the wind toppled it over then it would still maintain its shape. 

 

Next, we designed a 3D version of our emergency shelter. To help us make the 3D shapes we used an app called sketchup. We had to replicate our paper design. 

Lastly, some changes we think we could make is, getting rid of some of our pillars, because the storm is capable of blowing down the pillars which will make the octagon roll repeatedly, and we could take away one of the windows so that there's a less likely chance of things flying through it.

The things I liked was sketching the emergency shelter on sketchup and looking for different emergency shelters.

Here are some photos of our sketch up.

Understanding materials: warm/cold

Insulators are things that stop heat from travelling. The materials that kept stuff warm was the paper cup,tin,and paper. 

The best insulator for keeping things warm was the polystyrene cup. 

The best insulator for cold was the plastic cup. 

The materials were tested with thermometer. The materials that stopped heat from escaping was the glass and polystyrene. 

The insulator best for hot and cold is polystyrene because it has a lower number on both of the experiment. 

Here is the results of the hot and cold experiment.
