Hooked on Science - Bleeding Paper

October 8th thru October 14th


• Goldenrod Paper
• Baking Soda
• Water


STEP 1: Mix one cup of baking soda with one cup of warm water. Describe and classify the mixture by using its observable properties.

STEP 2: Dip the palm of your hand into the baking soda and water, slap your hand on a piece of goldenrod paper, and observe. Explain how the goldenrod paper can be used to help identify the mixture by its properties.


The goldenrod paper turns bright red when slapped with the palm of your hand, which is covered with baking soda and water.
Goldenrod paper is made from a dye which is a pH indicator.
The goldenrod paper turns bright red when exposed to a base such as ammonia or baking soda and turns a bright yellow when exposed to an acid such as vinegar or lemon juice.


PLEASE follow these safety precautions when doing any science experiment.

• ALWAYS have an adult present.
• ALWAYS wear the correct safety gear while doing any experiment.
• NEVER eat or drink anything when performing any experiment.
• REMEMBER experiments may require marbles, small balls, balloons, and other small parts. Those objects could become a CHOKING HAZARD. Adults are to perform those experiments using these objects. Any child can choke or suffocate on uninflated or broken balloons. Keep uninflated or broken balloons away from children.
