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

drinking water samples from different places using four of the standard drinking water tests required by the EPA. The experiment will be performed by a four person group‚ with each person providing a different water sample. The four tests to be performed are: pH‚ conductivity‚ phenolphthalein and total alkalinity‚ and total and non-carbonate hardness. Data from these four tests will be gathered and analyzed‚ drawing conclusions “about the validity of the data as well as the quality of water” (Kippenhan

Title Impact of water jet Objective The purpose of this experiment is to demonstrate the application of the momentum equation. The force generated by a jet of water deflected by an impact surface is measured and compared to the momentum change of the jet. To relate: • Direct measurement of impact forces • Effect of flow rate and velocity • Effect of various deflection angles Introduction / Theory Newton’s Second law states that The applied forces is equal
