Science Projects for Class 10th - Van De Graaff Generator
Van De Graaff Generator is the first idea for science projects for class 10th. Another name for Van De Graff Generator is a particle accelerator. This generator ionizes the air around by producing high volt differences.
- PVC Pipe 0.5″ X 2 ft
- 4 PVC Elbow
- PVC pipe as lower Roller 0.5″X4″
- PVC pipe as upper roller 2″x4″ Fixed Roller
- 2 Tee (PVC)
- Teflon Tape
- AC/DC motor (100 rpm)
- Metal Sphere
- Wire brush
- At the base, make a brush of thin copper wires from a thick electric wire.
- Set the brush beneath the roller and belt to eliminate negative charges.
- Connect the other terminal of this wire with a steel rod. This is done because negative charges have been producing at the lower end and positive charges at the upper end, so these negative charges have been drained out using the metal rod, or it can also be used for testing.
- Connect the lower roller to the shaft of the motor directly.
- Make a 2-inch wide belt out of the electric tape.
- Fix the 2-inch upper roller at the top. The reason for fixing this one is when the belt will move around, it will cause friction between belt and roller as a result of which, the static charge will be produced on it.
- Likewise, bottom one, make another wire brush by taking out copper wires from an electric wire. Set it above the belt so to draw charges through the wire to be accumulated on the steel pot.
When the motor is turned on, the belt starts moving. If it does not start moving, it is due to the high friction on the top roller so give it a slight push. Once it starts moving, it will rotate continuously. Make sure that there is no dirt on the roller as the generator might get stuck on the roller.
As soon as the generator starts, take a Neon bulb and bring it closer. You can observe a red glow. The intensity of light will vary depending on the distance of the bulb. By this method, you can also find the point where the field intensity is the strongest. You will notice that the charge has accumulated at the top.
Science Projects for Class 10th - Wireless Electricity Transfer
The wireless electricity transfer model is one of the most fun science projects for class 10th. Apart from it being fun to make, the wireless electricity transfer model is equally powerful. If made correctly, this model is even capable of charging a phone.
- 26 to 30 gauge copper wire
- ttc5200 transistor
- 2 resistors of 3.3 or 6.6 k ohm
- Tungsten filament bulb
- Pliers/wire cutters
- Battery/ Power Adapters (12V)
- 4 Diodes
- Cylinder/role with 8 cm diameter
The construction of this model required making two parts - Receiver coil and Transmitter coil.
- Take a coil and turn it 25 times. Now connect LEDs to the ends of the coil.
- Take a Cylinder with 8 cm diameter and whirl wire on it 55 times after leaving 3 inches.
- Make a loop for the centre terminal and whirl it again 55 times.
- You will get three terminals of the coil. Now take the TTC5200 transistor and connect its base to the 6.6 k ohm resistor.
- The other terminal of the resistor will be connected to one end of the coil and collector at the other end of the coil.
- Now connect the emitter to the negative terminal of the 12 V power supply.
- The transmitter will be ready after connecting the centre terminal of the coil with the positive terminal battery.
- To make the LED glow, place the receiver coil almost 15 cm above the transmitter.
Science Projects for Class 10th - AC Generator
An AC generator is used to convert mechanical energy into electrical energy with the use of magnetic induction. Learn more details on how to do this science project for class 10th students.
- Super Glue (Elfi) 20 ml
- 1/5′” PVC Pipe
- 4 Magnets
- 6” wooden Piece
- 6″ long Iron Nail
- Copper Wire 30 to 34 gauge
- Paper Tape
- Iron Strips 2
- Soldering Iron
- Drill Machine
- Iron saw
Making of Coil
- Measure 2 ½ inches of the iron strip and cut it into ten equal parts.
- Pile all parts together using paper tape such that there should be no space between strips.
- Now wound 300 turns of copper wire approximately around the bundle of strips vertically. To secure it, wrap the paper tape around it.
- You need two such coils to make an AC generator.
Making of Rotor
- Take half-inch diameter PVC and cut a piece of 2 ½ inches.
- With the help of superglue, stick four bar magnets on the piece of pipe.
- Make sure that the same pole of magnets are in an alternative manner.
- Make sure that the poles of magnets are aligned right by using another magnet.
- Make an axle using 6” long iron nails.
- Mark the length of the magnetic rotor after leaving half an inch from the tail of the nail.
- Wrap paper tape on the nail in a way that the magnetic rotor gets fixed on it.
Body of the Generator
- Take 6×6″ wooden pieces and two pieces of PVC pipes (one of 2″ and the other should be of 1″).
- Make a vertical groove on the 1 inch PVC pipe.
- Align it with a 2 inches piece and make a hole in it.
- Check if the axle is perfectly levelled after fixing the axle through both PVC pipes.
- With the help of superglue, stick the PVC pipes on the wooden base.
- Make two more coils as previously discussed, leaving both of their terminals outside the tape.
- Cut two half and a half-inch pieces of PVC pipes.
- Join the pieces perpendicular to the axle (one at each side) at the base.
- Fix coil on each of the PVC pipes.
- With the help of a lighter, burn the coating of coils at the terminals.
- To make the LED glow, join the LED with the coil and rotate the nail.
- If both the coils are connected in series, then the LED will glow brighter.
