  • Edible Rocks Standard Indicator Assignment #1 Science Standard 4.3.6 September 15 th , 2009 Kelly Clem
  • Science Standard 3 – The Physical Setting
    • Indicator 4.3.6 - Recognize and describe that rock is composed of different combinations of minerals.

  • Definitions
    • Edible - fit to be eaten as food
    • Observations - something that is learned in the course of observing things
    • Texture - the visual and esp. tactile quality of a surface: rough texture.
    • Mass - A measure of the amount of matter contained in or constituting a physical body.
    • Composed - to make or form by combining things, parts, or elements
    • Definitions from www.dictionary.com
  • Background Information
    • Think about some common ingredients in making cookies or other baked goods.
    • Think about how to compare and contrast different items.
    • Think about the questions, “What is a rock?”, “What makes up a rock?”, and “Are all rocks the same?”
  • What will we need?
    • Paper plate
    • Plastic spoon
    • Pencil
    • Hand lens
    • Balance
    • Edible cookies
    • Worksheet
  • Copy of Worksheet
  • Copy of Edible Rocks Recipe
  • Task 1: Observe
    • Put your edible rock on your paper plate.
    • Sketch your “rock” on your worksheet.
    • Use your hand lens to view your “rock” up close. Then, sketch the version of the rock you see through your hand lens.
    • List some of the properties of your “rocks.” (Hints: What color, size, shape, and texture does it have)
  • It’s all about the minerals!
    • Rocks are made up of many different minerals. Minerals are solid, naturally occurring substances.
    • Observing different properties in rocks tells scientists about the minerals that make up the rocks.
    • Your edible rocks are made up of ingredients instead of minerals. Write down what ingredients you think are in the cookies.
  • Task 2: Determining Mass
    • Using your balance, figure out the mass of your edible rock.
    • Next, take your spoon and carefully take apart your rock so we can study the ingredients inside. This is just like a scientist taking apart a rock to study the minerals inside!
    • Add any new ingredients you found to your original ingredient list.
    • What do you think the mass of the rock would be now that it is in pieces?
  • Last Task
    • Is the mass of the rock in pieces the same or different from the mass of the rock as a whole?
    • Find the masses of each of the individual sections of the cookie.
  • Summary
    • All of the ingredients put together make up the edible cookies, just like combinations of minerals make up rocks in nature.
    • The mass of a whole object is equal to the sum of the masses of its parts.
  • Questions
    • Would the edible rocks have been the same had I substituted chili powder for flour and nuts for raisins?
    • How do combinations of minerals make rocks look different from one another?
    • Why was the mass of your rock as a whole the same or different from the mass of your rock in parts?
    • Extension question: Where else have you heard of minerals? Have you heard of minerals in foods?
