AUTOMATIC WATER PUMP CONTROLLER The automatic water pump controller is used to control the water pump motor. The motor gets automatically switched on when water in the overhead tank (OHT) falls below the lower limit. Similarly‚ it gets switched off when the tank is filled up.

molecule of water A chemist’s view of the world is not as narrow as one might think! Yes‚ we start with the atom‚ and then go on to the rules governing the kinds of structural units that can be made from them. We are taught early on to predict the properties of bulk matter from these geometric arrangements. And then we come to H2O‚ and are shocked to find that many of these predictions are way off‚ and that water (and by implication‚ life itself) should not even exist on our planet! But we soon

of Alcohol vs. Caffeine on Water Flea ’s Heart Rate. Title Page Abstract For our most recent experiment we tested the effects of immersing water fleas in caffeine and alcohol to see the effects on their heart rate. Before the experiment we hypothesized that if you place the water fleas in alcohol then their heart rate will slow down‚ and if you place them in caffeine then their heart rate will raise. For this experiment we needed water fleas‚ tap water‚ two pipettes‚ a microscope
