Science Fair ideas, Win Awards – Project # 9 – Submarines

[ad_1]

target

To find out how to use the submarine propellers and stabilizer fin movement.

Introduction

Although the submarine saw a movie seems to glide along effortlessly, in fact, combat forces of gravity, pressure, friction, and buoyancy. Have you met them in real terms in the previous experiments science? fair trials for all other sciences, is one of the best, as you will understand that these forces cease the submarine.

material

A 500-ml bottles, a soda bottle (2 liter), knives, scissors, two large paper clips needle nose pliers, rod, three rubber bands, hard ruler, a silicone, a bath or pool

production

the Propeller

This is a real experiment is one of the science, which will require the help of an adult.

• Cut the soda bottle (2 liter) in the half. Take the bottom for making a special curved blade propeller 5.
• Two holes must be drilled in the propeller, in the center, and a little off-center.
• Cut a circle out of a plastic 2-liter soda bottle remaining. They bore a hole in the middle of this circular piece of plastic, and the submarine cap.
• a free end of a straightened paper clip to be passed through the cap on the bottle, the circular plastic and the propeller center hole. The free end to be bent back and not passed through the centered hole in a manner to hold the cap, the plastic pieces and the propeller are closely related, but allows the propeller to rotate.

The Submarine

• bottom drilling two holes in a 500 ml bottle similar propeller holes.
• Now it is fed at the end of a straightened paper clip on the inside of the glass with a center hole. Bend the tip of the free and pass the non-centered holes. Secure the clip, so that it will not turn. This part is very difficult, so use a chopstick.

between

• Attach a rubber band clip on both hooks. A tightly stretched rubber band must hook the glass base and hook the cap.
• Attach using the middle of the ruler perpendicular to the body in the form of two water bottle with a rubber band “X”. The ruling of the stabilizer fin.
• Now use a waterproof sealant to close the clip hole in the bottle.

The submarine is ready.

Submarine testing

• Fill three-quarters of the submarine water bottle and put the cap back on.
• Turn the propeller potential energy to build a rubber band. Science fair experiments require that describes all the activities. So count the number of turns and write this number on the lab book. You need to turn the propeller that many times in the future.

Procedure

Now it puts the fin stabilized the front, center and back in different ways and have some fun observing how the submarine moves. Record your observations each time. Use the below mentioned ten positions.

1. No fins-
2. Near: Fin-center
3. Near: Fin moved to the right –
4. Near: Fin moves to the left –
5. Front: Fin-center
6. Front: Fin moved to the right –
7. Front: Fin move to the left –
8. Back: Fin Center –
9. Back: fin is moved to the right –
10. Return fin move to the left –

to the observations allows answer the following questions:

• What happens if there was a stabilizing fin?
• What is the best position of the fin?
• Why it is important stabilizer fin of a submarine?
