Science is the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment.
Here's the written response answers! Make sure to reword my responses.
17) Science is "a branch of knowledge or study dealing with a body or facts or truths systematically arranged and showing the operation of general laws." An example of a type of scientist would be a geologist. A geologist studies rocks. They research about how rocks are formed and how they erode. They learn about all different types of rocks.
18) A scientific theory is an explanation whereas a scientific law is an observation.
19) A great example of this is baking. If you can understand the scientific principles of an ingredient it can help you understand how that ingredient works with different ingredients. If you are not sure why your cookies turned out flat, you can think scientifically and find a solution to make your cookies turn out not flat.
20) The scenario could have been prevented if Krystal had waited for a better time to wish her a happy birthday and if Carin wore proper attire. She should be wearing closed toe shoes. The students should respond by Carin washing off her feet in the nearest washing station to ensure that she does not walk too much. After Carin is done washing off the chemicals and the glass she needs to seek professional medical help to make sure that there are no other injuries.
