The Water Tower

Well grade 7's its time once again to get your brains wrapped around a brand new Technology project.

This term we will be covering Structures, and you guys will have build a water tower.  The raw materials we are using are paper pipes made from old telephone book pages and flour paste.

First up, we will complete the activity sheets in our textbooks, so that we get an idea of what structures are.  Remember structures come in three types: Frame structures, Shell structures, and Combination structures.

The water tower will be built on a frame structure concept.  The paper pipes will represent steel pipes in a real water tower.

Here's the scenario:
A village in Lesotho has a problem with water supply.  The government has just installed water pumps at various locations so that water can get pumped from the underground water sources.  The problem is that the pumps work with electricity, and at times the electricity cuts out in the village.  The villagers need a storage system which will enable them to collect water that is pumped so that they can use the stored water when the electricity gets cut.

Your mission is to build a water tower for them which can carry a 2000lt water storage container.  The tower must be sturdy, it must be at least 15 meters high so that the water pressure from the container will be significant enough to push water from the storage tank to the taps below.

Step 1:  Investigate different types of water towers and how they are constructed.
Step 2: Get into groups and design a water storage tower which will be able to fulfill the needs of the village.
Step 3: Build a model of the tower.  The model should be 50 cm high and 30 cm wide.
Step 4: Make a presentation using the presentation software on the Tablet Pc to show to the village when you propose that they use your water tower.

Total marks for the project is 100 marks.
  1. Investigation = 20 marks
  2. Design = 20 marks
  3. Model = 40 marks
  4. Evaluation = 5 marks
  5. Proposal/Presentation = 15 marks

Good Luck!
