1. Pure Pacific Water

Camilla, Luanne, Juliet, Kathryn and Lomot

Brief: Our main aim for this project is to build a prototype that can dispense water. It is built simply by hard work and determination. We built this prototype for students in our school to wash their hands, and learn the importance of hygiene. The main materials are timbers, containers, tubes and silicone. But, the main thing that helped pull our prototype together was through girl power!

Materials:

  • Nails, Timber, Silicone, Hose (pipes)
  • 2 x Orchy bottles, 2 x taps
  • 1 x big container (main material)
  • 2 x flat surfaced timber

How it works:
1. Pour an amount of water to the big container
2. The water will flow down to the two pipes into the two Orchy containers
3. Wait for a while for the water to settle in the two Orchy containers.
4. When it’s settled down, turn the taps to wash your hands.

This is one way on how we can re-cycle the used water: You can still use it to water the plants.
It is excellent that two people can use the taps at the same time.
I like the girl power!
The materials look as though they could be easily replaced.
The only problem is if someone with contaminated hands touched the tap - then disease could be passed on.
It would be nice to see soap included too.

A good simple poster that give you all the information you need. I really like the poster where it shows that cleaning nails is a good idea.

2. Water Guardians

Cynthia, Moyinoluwa, Kimberly and Kallie

Brief: We the water Guardians have constructed a simple device. The Purpose of this device is to wash your hands regularly and promote a good lifestyle and at the same time making it as a fun habit.

Materials: -plywood -timber(for the stands) -nail -silicone (water proof) -funnel-PVA glue -tap –bucket -container
How It Works
1.Using the small container refill the big container with water.
2.Wait until the water has passed the tap.
3.Gently turn on the tap

Recycling of water We the water guardians have decided to recycle the used water to water our plants.

The Water Guardian's Hand Sanitizer recipe and poster.
I like the way you say handwashing should be a fun habit. That is good. It is also good that the plants get watered.
The hand sanitiser recipe looks effective but I rather think that soap might be a better idea. If you can't get your hands on soap then mud, plants or sand - something that can be physically rubbed on the hands - can be effective.

A good poster and recipe. I wonder if the aloe vera might make the recipe go off after a while? How would you keep it if there was no fridge?

3. Water Crew

Members: Sylvana, Trevor, Kingstimer, Maxwell and Ezekiel.

Brief: My group and I are doing a hand washing device that is not very simple. We are doing the device to show that we need to have a healthier lifestyle, so we can show that water keeps everything healthy and fresh. The device is a hand washing type and it dispenses an amount of water that is enough to wash away germs and also killing them by using a sanitizer.

MATERIALS:  3 by 3 wood (60cm all around), 50cm wood, Patty, Nails, Sandpaper, Hose 2x, Hammer Drill, Puncher, Silicone glue, Electrical wood cutter, Containers 2x
HOW IT WORKS

  1. POUR WATER INTO THE FIRST CONTAINER, INORDER TO FILL THE SECOND CONTAINER…
  2. THEN OPEN THE TAP TO LET THE WATER RUN OUT THE HOSE.
  3. WHILE THE WATER IS RUNNING, WASH YOUR HANDS USING THE SANITIZER...
  4. AFTER THAT CLOSE THE TAP TO SAVE WATER
  5. WHEN YOU ARE DONE WIPE YOUR HANDS USING THE TISSUE.
  6. AFTER USING THE WATER WE WILL USE IT TO……
    *WATER PLANTS… *WASH THE DUST OFF THE GROUND

Health educational material
I like the reservoir idea. I would suggest that to save water, wet hands, close tap, use your sanitiser, and the wash it off. Water is heavy and you don't want to be carrying it too far.
What would you use if there was no sanitiser?

I am awfully sorry but even though I blew the image up as big as I could, I couldn't read the words on your poster. it looks lovely and colourful though!

4. Water Proof

Group Members:, Samuel,  Dez, Glenmore and Nathan

Brief: The device that we have made is simple and is used for students to wash their hands before eating lunch. And washing your hand is clean and healthy…

Sanitizer:  Our group has deiced to buy a readymade hand sanitizer to wash our hands.

Prototype

Materials:
3x containers, 4x pipes, 1x wooden stand, 1x silicone
1x hammer, 1x packet of nails                                     

How it works

  1. Firstly you pour some water into the large container.
  2. Than let the water flows through the pipes.
Finally the water comes out of the holes/taps, and you can wash your tidy hands.  

Recycling of water:

We can recycle water by…..

  1. Watering the plants after using the water to wash your hands.

2. putting it in a machine that cleans out germs and bacteria.

See health materials here.
I can see you have worked hard on your project.
What would you use if there was no sanitiser? You have to think how many hours does the person have to work to be able to buy it? One thought I had while reading this is to use left over tea leaves. The water has been boiled to make the tea so it is clean. Also there is tannin in the tea that could be helpful.

Good common sense and good instructions. Well done.

5. Water Foundation

Group members: Raylene, Solester, Crystal & Dianne
Brief:My group and I have built a prototype gadget and a hand sanitizer for our class to use for washing hands and it’s also importance.

It is very simple to build once you work as a group like what we have done.

Hand sanitizer: We have bought a bar of soap to use as our Hand sanitizer.

Prototype
Materials
5x ply wood , 1x pure azz containers , 2x Orchy containers
1x long Rubber hose (pipe), 1x packet of nails, 1xwood glue /silicone
2 x buckets
How it works:
Method steps:
Step 1:Pour water into the small container at the top
Step 2: The water flows down the pipes to the larger containers
Step 3:  Waste water goes down the pipes and you wash hands. Waste water goes into the buckets.

Usage of waste water: Pour waste water into flower gardens at school.

This looks really good. It is also a good idea to use a small container to fill the large. Water is heavy to carry as you have no doubt found out.
However I am sure you will find that a bar of soap would be cheaper to buy than sanitiser.

My group and I have been working on a simple handwashing device for these past week. Our main purpose is to make a very successful way of washing hands with less water.

Sanitizer…  to make the sanitizer you will need….
2 aloe vera, 1 lemon, 2 drop of dishwashing detergent, 12 mint leaves, some water. .     How to make the sanitizer… 

  1. Firstly squeeze aloe in a bottle.
  2. Then put mint in bottle then pour warm water in bottle
  3. Add dish washing detergent and shake well.         

Materials - What you will need: *A hammer, Silicon, Timber, 4 containers  

  1. Firstly pours sanitizer into the right container.        
  2. Then pour pure water into left container.      
  3. Then open taps and let the water flow

 To recycle: Lift the bucket and water the plants.                                              

Your simple handwashing device will certainly work. The only problem is if someone with contaminated hands touched the tap - then disease could be passed on.
The recipe for sanitiser sounds good. It will certainly clean hands. Did you make it and did it smell nice? Also, can you grow Aloe Vera in Moresby?
Unfortunately the poster is a little too small to see the detail.
 

Group members: Darley, Valynther, Edith, Alma and Leonine

Brief: The gadget that my group and I have built is mainly to save water and always have clean hands. In Papua New Guinea most citizens get sick and lose their lives because of contaminated water and unclean hands. My group and I built this gadget to cut down sickness and make washing hands a fun way of our lifestyle.

Prototype/Gadget:
Materials
-Wood, Silicone, Nails, Hammer, Container, Short Rubber Hose, Lid
How it works:
Firstly you fetch water into a container and pour it into the first container and wait for it to fill the next container. Lastly open the lid to wash your hands.

Recycling of water:For our group we decided to recycle our water by giving it to the plants.

What a good name! I like your comment about handwashing should be a fun activity.
I have one question. Do you empty the container? If you don't then germs could grow in the container. Even opening the lid t contaminated it if one of the students had dirty hands.

A good poster with a good message. Well done!
