To make a potato clock, connect two potatoes to a low-voltage LED digital clock with copper wire, galvanized nails and alligator clips. This easy chemistry project demonstrates the concept of electrochemical cells, in which chemical energy is converted to electrical energy.

Create a strong hypothesis using this basic form: "If (I do this), then (this) will happen." A hypothesis is simply an educated guess.

Some good hypothesis examples include, "When there is less oxygen in the water, rainbow trout suffer more lice" and, "Aphid-infested plants exposed to ladybugs have fewer aphids after a week than untreated plants." Effective hypotheses are simple enough to be testable, but not so simple that they ar

Examples for writing a hypothesis are available at Sciencebuddies.org and Softschools.com. In addition to examples of hypotheses, Sciencebuddies.org provides a hypothesis checklist to help users determine the effectiveness of their hypotheses. Softschools.com gives an in-depth explanation of the hyp

In science, a hypothesis is an idea about how or why something works that must be carefully tested in order to verify whether it is true or false. To test a hypothesis, a scientist must follow scientific method so that the hypothesis can be verified or refuted by other scientists.

A strong hypothesis should meet three fundamental criteria. It needs to state the hypothesis in the proper conditional phrasing. It needs to clearly establish the relationship between the variables included. Finally, it needs to establish that said relationship is scientifically provable.

A basic hypothesis test measures the outcome of a probability function or equation for the validity of an expected or returned result. Typically, a basic hypothesis test uses accumulated data points as the basis for rejecting or accepting a hypothesis. This is done mathematically or using empirical

The five steps of hypothesis testing are stating the null and alternative hypotheses, determining the test statistic, finding the probability of test statistics, determining the level of statistical significance, and making a conclusion about the hypotheses. Hypothesis testing allows the validity of

According to The United States Potato Board, seven types of potatoes are commonly enjoyed by consumers: russet, long white, round white, fingerlings, red, yellow and blue or purple. The potato industry refers to them as table-stock varieties.

An "if, then" statement is an example of a scientific hypothesis; for instance, "If I brush my teeth daily, I won't develop cavities." The null hypothesis, a statement that there is no difference between two variables, is another hypothesis type. For example, "All trees have the same number of branc
