Exercise 1: Sediments are a Piece of Cake
(A layered cake will be needed for this activity. For preparation instructions, click here.)

1. You or your group should be supplied with a straw, journal pages, colored pencils, and a ruler. (Straws can be cut to a length slightly higher than the cake.)

2. Look at the layer cake (provided by your teacher). How can you learn more information about the cake without peeling the foil back or cutting the cake open? Draw what you think the inside of the cake looks like in your journal. What type of cake is under the icing? Is there a filling inside? Make your best hypothesis.
