We want to make some easy working models like mini cooler
For class seven , A model of a WIND MILL really works .a wind mil produces a lot of electricity through air or water .it is very useful in the irrigation and houses . It is very useful in the conservation of thermal electricity as we are running out of the main resources like coal .
Please show physics working models for class 7 , its emergency please
You can make a lava lamp or you can put mentos in a bottle of coco cola to see how the cola burst out of the bottle and then explain it
Working:electricity:windmill using a dynamo
A volcano using eno would be amasing
Hi,I am Shikhar800, to make such model :-Apparatus:- Glass(transparent cup), candle, matchstick.What to do? :- Take a candle and lit it with the matchstick. Then invert a glass and place it on the candle. After sometime the candle will extinguish! This is because of the absence of Oxygen in the glass.
