Introduction to the Scientific Method

In this activity (page 26 of the PDF), learners make observations, formulate hypotheses and design a controlled experiment, based on the reaction of carbon dioxide with calcium hydroxide. This is an introductory activity in "The Brain in Space: A Teacher's Guide with Activities for Neuroscience" but can be used to introduce any group of learners about the scientific method. This activity requires 3 days of 40-45 minutes of learning each day. The lesson guide includes background information, variations depending on age/level, and post-lab discussion suggestions.
