George washes dishes with a new scented dish soap. After washing the dishes, he thinks they are cleaner using the new scented soap. What can he do to be sure that the new scented
dish soap cleans his dishes better than the old dish soap?

Please find the set up of the experiment below

Independent variable: DISH SOAP

dependent variable: Cleanliness of the dishes

Explanation:

In order for George to be sure that the new scented dish soap cleans his dishes better than the old dish soap, he will set up an experiment using the scientific method.

The scientific method has the following steps:

1) Ask a question: Every scientific experiment starts with a question. I'm this case, George will ask the question that: Does the new scented dish soap clean dishes better than the old dish soap?

2) Formulate a hypothesis: A hypothesis is a testable explanation to an asked question or observed problem. A hypothesis in this case will be: IF the new scented dish soap is used, THEN dishes will be cleaner.

3) Test hypothesis: A hypothesis is tested by conducting an experiment. In this experiment, George will compare the effect of the old dish soap to that of the new scented soap. He will wash a group of plates with the old dish soap and wash another group with the new scented soap. He will then compare how clean the groups of dishes are.

In this experiment, the INDEPENDENT VARIABLE, which is the variable George manipulates is the DISH SOAP while the DEPENDENT VARIABLE, which is the variable George measures is the CLEANLINESS OF THE DISHES.

The control group is the group of dishes washed with the old dish soap while the experimental group is the group of dishes washed with the new scented dish soap.

The control variables of this experiment can be the same type of plates, same color of plates, same type of food eaten with the dishes etc.

4. Conclusion: Concluding in an experiment involves accepting or rejecting the hypothesis depending on the outcome of the experiment. If the outcome aligns with the hypothetical statement, the hypothesis will be accepted but if otherwise, it will be rejected.

Why do you suppose the structural polysaccharide cellulose does not contain branches? why do you suppose the structural polysaccharide cellulose does not contain branches? branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby decreasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby increasing the rigidity and strength of the microfibrils. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby increasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.
