PROJECT- WATER OVERFLOW ALERT

-
Hello guys! today we are making a project which saves water and alert when tank water overflow from tank, especially we are wasting water by this we can conserve water for the future generation. So lets start.
Material used:-        
        
1.Cardboard
2.Buzzer
3.Battery 9V
4.Wires
5.Container
6.Battery connector
7.Board pin 2
8.Tape
9.Scissor

HOW TO MAKE A WORKING MODEL?
  • Take a cardboard and fold it, cut four tapes pieces and paste it on the four corner of cardboard.
  • Now the cardboard tray is ready to make connection on it. 
  • Paste buzzer on the cardboard tray with the
    help of tape and take a wire cut into two equal pieces and peal off wire on both sides.
  • Attach battery connector with battery connect positive wire of battery with the buzzer positive wire
  • Join one wire in the negative wire of buzzer and another wire join with negative wire of battery connector.
  • Now we have two remaining free wire, attach board pin on both wires rotate the wire on board pins so that he can fix it.
  • After that take the board pin and pressed it on the bottom of container and another board pin pressed it on the top of container now the circuit is completed now.
  • Paste the container on the cardboard tray with the help of tape. https://en.wikipedia.org/wiki/Water_detector

Hello guys! today we are making a science project through which we understand how heavy cars can be lifted through jacks. Which liquid  is used by them to lift cars. what is the process and mechanism of car jack. so lets start now. PROJECT-CAR JACK Objective:- To understand the concept of car jacks Material used:-  Cardboard sheet 2 Syring 1 Platic pipe 0.5metre Double sided tape 1 Small toy car Water Tape Scissor https://en.wikipedia.org/wiki/Hydraulics HOW TO MAKE A WORKING MODEL?   Take a syring fill up water then attach plastic pipe in the syring after that press planger so that water goes through the pipe and air can be released from them refill water on the syring fully through plastic pipe . Attach another empty syring with the plastic pipe now we have a pair of syring. Take a square shaped cardboard and with the help of scissor mark three straight lines in the cardboard sheet paste a syring on the ...

                                            PROJECT- BOTTLE TORCH   Objective:- To understand the concept of simple electric circuit by making a working model of bottle torch. Material used:- Plastic bottle Big L.E.D. Battery 9Volt wire  1Metre Aluminium foil sheet Switch Battery connector Resistor HOW TO MAKE A WORKING MODEL? Take a bottle and cutted half upper part  of bottle(funnel). Make 2 holes in the bottle cap with the help of scissor. Take a wire break into two piece having same length and peel off from both sides. Insert l.e.d. in the bottle cap and attach wires on both terminals of l.e.d. make sure which one is positive(big leg) and negative(small led). Join positive wire with the battery connector (red wire) and paste a small tape on it. Join negative wire in the one switch terminal and same as join another remaining ...
