Middle School Science Lessons

Its BACK!!!! Link undated April 2025

This classic interactive website 👩🏻‍💻 is a great way to practice identifying acidic, basic, and neutral substances along with reading pH values. There are three different levels which increase in difficulty as the students complete each activity.

• Lesson Materials:
  • NEW! Student handout (Google doc, view only, make a copy to edit)
  • Old Student handout (pdf) with instructions to record their results
  • Lawrence Hall of Science – Alien Juice Bar

Challenge 1 – students have to identify and categorize the different ‘juices’ that they will serve to the aliens as either Acids, Bases, or Neutral.

Challenge 2 – students will practice serving requested juices to aliens, but if they serve a juice from the wrong category, aliens can become sick, or worse!

Challenge 3 – students have to change the pH values of the juices on the tray by either adding acids or bases to raise or lower the pH values.
