The Hypothesis is a Question of " What If?". Experiments are performed to show what actually happens.
Scientists collect raw data on Antarctica, rather than performing experiments. Experiments are held back for performance in their domestic laboratories, sometimes using the raw data collected on the continent.
They set out to test a hypothesis by using experiments and controls. They then adjust the experiments and run the tests again until they either prove or disprove it.
The Indian scientists design one! Or the activity is carried out using man-power.
A sentence using theory in its scientific sense would be " Many scientists have a theory about why global warming exists." Theories are based off experiments and facts.
Scientists answer questions by using the scientific method (making observations, doing experiments, formulating, testing, and modifying hypotheses). In all experiments where this process has been used to test its validity, astrology has failed.
scientists are using plants in their experiments. long ago, the people are used to respect the plants , they are not allowed to even to pluck the flower. they always take out the time and give water to the plants .this was very good and particular in their days so the scientists plucks the flowers and the people do not give water to the plants so we should give water to plants and also not to pluck off the flowers
Every new (and approved) technology leads to another one. This way, scientists get a lot of advantages by using them on their experiments.
