This probably isn’t the first time you’ve heard the word ‘acid’. What does this word make you think of?

Activity: Make an Egg without a Shell

This is one of our favorite activities. You start with an ordinary chicken egg. Leave it in vinegar overnight & the acid dissolves the eggshell. You end up with a egg that’s held together by the flexible membrane inside the shell.

You’ll find detailed instructions on how to make a “naked egg” on the Exploratorium’s Science of Cooking website.

Activities: Taste the fizz

You’ve seen that adding baking soda to acid makes it fizz. Here are two activities that use that fizz to make tasty treats.

New Zealand’s Science Kids explain you how to make fizzy lemonade.

The folks at Planet Science explain how to make a candy treat called sherbet. Watch out! This candy zaps your tongue with fizz.

Who knew science could be so tasty?

Activity Prep

Print Prep

In this Mystery, students are introduced to acids, a group of substances with a reputation for being reactive. In the activity, students test the properties of a series of unknown liquids in order to identify which are acids.

Preview activity

Supplies you'll need for students

For classrooms, we recommend students work in groups of four. Homeschool students can work alone. Each group of four students, or each single homeschool student, needs:

  • 1 set of handouts
  • white vinegar
  • salt
  • baking soda
  • orange juice, lemonade, Tang or other drink containing citric acid
  • mustard or ketchup
  • toothpicks
  • small cups (e.g. 3 oz bathroom cups--plastic ones can be washed and re-used. Beware that paper cups filled with vinegar start leaking after an hour)
  • spoons (plastic or metal)

Supplies you’ll need to make Bean Water and the three Unknown Liquids

  • a measuring cup
  • a tablespoon
  • 2 bottles that hold at least a pint each (Check the recycling bin. You will use them again in Mystery 3)
  • 1 cup of dried black beans
  • a bowl or jar (1-quart capacity for a small group, 2-quarts for a large class)

What you'll need to do before class

  1. Measure out and set up the supplies (here’s how )
  2. Make Bean Water (here’s how )
  3. Create the Unknown Liquids (here’s how )
