1. ACTIVITY SHEET #3 (TURBINE MODEL)
Objectives:
At the end of the activity, you should be able to:
construct a simple turbine unit
demonstrate mechanical energy transformations, and
demonstrate Hydroelectric Power (HEP) using a water reservoir system.
Materials Needed:
Plastic folder or acetate
Permanent marker pen
Ruler or tape measure
Pair of scissors
Cutter
Juice drink straw/Ballpen case
Hot melt glue or super glue (cyanoacrylate adhesive)
Masking tape
Thread
5-10 pcs paper clips
2 1.5-Liter plastic bottle
1 push pin
3-inch nail
2 3-Liter ice cream container
2-Liter bottled tap water supply
Safety Precautions:
Danger of injury from the pair of scissors and cutter.
Danger of eye or skin injury from glue
Use of water container for collecting water.
Use of towel or rag to dry off wet surfaces.
Follow all safety lab rules.
Procedure:
A. Construction of the Turbine Model
1. Prepare 8 blades for the turbine. Cut 2 inch by 1 inch strips of plastic folder or
acetate. Shape it any way you want.
Figure 6. a) Shaped strips for turbine blades
2. 2. Glue the blades to the middle of the straw similar to the sample in Fig. 6 b).
The straw will serve as the shaft of the turbine.

3. Make a turbine holder using one of the plastic bottles. Use a push pin then a
3-in nail to make holes at a 10-cm height to hold the straw. Ensure that the
turbine can rotate freely. If needed, make some plastic stopper to hold the
turbine in place.
