Screen Shot 2015-03-05 at 11.29.30 AM

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.

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.
