Answer:
The correct sequence of scientific steps in Sienna's study of movement in plants, according to the scientific method, are:
Make an observation: Sienna observes that certain plants seem to move throughout the day, and wonders why this is happening.
Ask a question: Sienna asks herself why some plants move throughout the day and others do not.
Form a hypothesis: Sienna comes up with a possible explanation for the observed plant movement, such as the idea that plants move in response to changes in sunlight.
Design and conduct an experiment: Sienna sets up an experiment to test her hypothesis. She might expose different groups of plants to varying levels of sunlight and observe how they respond.
Collect and analyze data: Sienna collects data on how the plants respond to different levels of sunlight, and analyzes the data to see if it supports her hypothesis.
Draw conclusions: Sienna evaluates her data and draws a conclusion about whether her hypothesis was supported or not. If it was not supported, she may revise her hypothesis and conduct further experiments.
Communicate results: Sienna shares her findings with others, such as through a scientific paper or presentation, so that other researchers can build on her work.
