Twirly can be a great activity for introducing how to do a scientific investigation
Students are given a twirly and drop it which is followed by careful observations about how a twirly works. With materials (e.g., different sizes of twirlies, paper clips, different kinds of paper, etc.), students are asked to generate a question to answer and to design and conduct an investigation. Students might compare “the time for a complete drop” with “different sizes of twirlies”, “different types of paper”, “different mass of a twirly”, and “different types of wings on a twrily”.
A discussion can deal with an understanding about inquiry that a scientific investigation begins with a question and skills for doing a scientific investigation, such as generating a scientific question, controlling variables, repeating an investigation, and analyzing and presenting data.
