Introduce or review the scientific method with a "magic" bottle that can hold pencils, straws, and even string suspended in mid-air! This is ALWAYS an attention-grabber in the science classroom! It was created for High School Chemistry, but can be used in middle school, and even elementary school classes. Depending on grade level, you can make the scientific inquiry as detailed as appropriate. By guiding students through a simple repetition of observation, hypothesis, experiment, and conclusion, you can reinforce the steps of the scientific method.
This download includes:
1. List of materials needed, and instructions, to make the bottle.
2. Step-by-step instructions for performing the demonstration.
3. Worksheet for students to follow along and make hypotheses, experimental ideas, and conclusions (this is a middle or high-school level worksheet).
The ZIP file includes and EDITABLE docx version, and a non-editable PDF version.
Materials required to build the "magic bottle" include:
-bottle or flask (I use a 500mL Erlenmeyer Flask)
-small, squishy nerf-type ball
-small "test objects" like paperclips, pencils, and string
This demonstration could be used for General Science, Biology, Physical Science, Chemistry, or Physics.
