She has learned that when scientists do experiments, they follow the steps of the scientific method. The scientific method is an orderly way to study a topic of science.
It goes like this;
#1 Ask a question. ( what do you wnat to know?)
#2 Reasearch the topic. (learn all you can about your topic)
#3 Write a hypothesis. (this is an educated guess)
#4 Plan your experiment. (decide what materials you need and gather them, plan your steps)
#5 Do the experiment. (follow your plan)
#6 Write a conclusion (summarize what happened)
#7 Share your findings (like all scientists, you should share your findings with other people at the science fair. Create a display that shows how you did your experiment and what you learned. Make sure to include your notes, graphs, illustrations or photographs.
