STEM Middle School Classroom Project
Using a 2-liter filled with water and a "diver" (eye-dropper, partially filled with water), students will explore the relationship between the pressure they excerpt on the bottle and the change in density of the diver. They will further explore with their group why the density of the diver is changing—through observation.

This kit includes
teacher instructions, student instructions (worksheet), grading rubrics, a demonstration video for the teacher, a materials needed sheet, and the related NGSS standards!
In the teacher demonstration video
, I give you an overview of the activity challenge, talk about the materials involved and where to get them, demonstrate how to set up the challenge for the students, and discuss the science involved. Teachers have found these videos to be very helpful by showing them step-by-step how to run the activity and giving them a better understanding of the science behind it.
This activity will challenge students to work together in groups to complete the given task. These activities are fun, engaging, and the students will learn science in the process. Group work and problem solving are at the heart of these challenges.
Each activity challenge will end with a real-world
research question, video, or activity. It is usually an extension of what the students just discovered and learned. The students will be involved, excited, and looking forward to future activity challenges in your classroom.
NOTE: This product is a PDF file but also contains a link to all of the editable files
in a google drive folder. This gives you the ability to edit any rubrics or worksheet questions to fit your class!
These activity challenges have been very popular as individual products, so I've decided to sell them in packs at a discounted price. I have combined them into 4 packs (20% off list price), 8 packs (25% off list price) and a 16 pack (37% off list price)
. Here are the packs that include this activity.
