A horizontal infographic on a white background titled "THE SCIENTIFIC METHOD" in bold navy blue text. The flowchart features eight interconnected light blue boxes, each containing a dark blue icon and a label. The steps are: Observation (magnifying glass), Question (thought bubble), Hypothesis (lightbulb), Experiment (beaker), Data (bar graph), Analysis (document with magnifying glass), Conclusion (checkmark icon), and Repeat (circular arrows). Arrows point from left to right between each box, and the website URL "www.thesciencenotes.com" is printed in the bottom right corner.
