What is data in the scientific method? Data are the information gained from observing and testing an experiment. Scientists use data to gain understanding and make conclusions. Scientists often use graphs or tables to show their data and research findings. What are the steps in drawing a conclusion? Important Steps for Drawing Our Conclusions 1) […]

What qualifications do you need to be an astrophysicist?
What qualifications do you need to be an astrophysicist? You would need a degree in astronomy or astrophysics. For entry, you generally need 4-5 Highers including Maths, Physics and usually another science subject. You then need to do specialist postgraduate study, usually a PhD, to get a post as a professional research astronomer. Does NASA […]

How many total oxygen atoms are there in the reactants of photosynthesis?
How many total oxygen atoms are there in the reactants of photosynthesis? six atoms Where do the oxygen atoms go? The single oxygen atoms latch onto O2 molecules to form O3 (the chemical formula for ozone). The stratosphere has higher concentrations of O3 because there is more UV present. The ozone layer filters out UV, […]
Why does a metal spoon feel colder than a wooden spoon?
Why does a metal spoon feel colder than a wooden spoon? Even though they are the same temperature, the metal will feel colder than the wood because of the thermal conductivity of the metal, compared to the wood. It is because the metal conducted heat faster that it feels colder than the wood, which conducted […]
What happens when chlorine gas is treated with cold and dilute caustic soda?
What happens when chlorine gas is treated with cold and dilute caustic soda? Solution. When chlorine is passed through cold and dilute caustic soda solution, a mixture of sodium hypochlorite and sodium chloride is formed. How does sodium react with water? When sodium is added to water, the sodium melts to form a ball that […]
What is the role of stomata in gas exchange?
What is the role of stomata in gas exchange? Stomata are tiny holes found in the underside of leaves. They control water loss and gas exchange by opening and closing. They allow water vapour and oxygen out of the leaf and carbon dioxide into the leaf. What are stomata mention their importance? Stomata serve a […]
Why do electrons transfer from a sweater to a balloon?
Why do electrons transfer from a sweater to a balloon? Since electrons have a negative charge, the balloon now has a negative charge. But the sweater fibers lost some of their electrons, so now the fibers have a positive charge (they have more protons than electrons). Positive and negative attract so if you bring the […]
What will happen if tectonic plates are not moving?
What will happen if tectonic plates are not moving? One big problem with plate tectonics stopping is that plate motion is the mechanism by which Earth is cooling down and getting rid of its internal heat. If the plates stopped moving, the planet would have to find a new and efficient means to blow off […]
