This is the PowerPoint I made to introduce the steps of the scientific method to my students. It includes descriptions for the following steps:
1) Big Question/Problem
2) Form a hypothesis
3) Conduct the experiment
4) Make observations and record data
5) Analyze data
6) Form a conclusion
It ends with one of the many SpongeBob scenarios you can find on the web. It's visually appealing and direct, so it can be used as a quick mini-lesson before more individual or guided practice with students.
