Results and observations of scientific experiments should be properly recorded under headed columns and numbered rows. The headings must include the units in which each quantity is measured. Graphs are very helpful in comparing measurements. The general rule in plotting the graph of a given ..

Chris played a maze game 13 times. There are 5 ways to exit the maze. Chris went through different ways to exit. Using the following data, find the experimental probability of Chris going through way B. Way to exit Number of times Chris went through the way Way A 4 Way B 3 Way C..

The molecular mass (or molar mass) is obtained either from the experimental data or from the vapor density of the compound by using the relationship, Molecular mass = 2 x Vapor dens..

Although Rutherford's model was enormously successful at explaining the scattering of alpha particles, there was a problem when the experimental data were used to calculate the mass of the nucleus. From the results of the scattering experiments, it was possible to calculat..

. While making hypothesis about a phenomenon, the marker should avoid teleological explanations. Teleological explanations are the beliefs that a phenomenon or event occurs in response to some need or purpose. Such explanations do not lend themselves to verification. 4. Testing the hypothesis throu..
