This is an "Easter" themed laboratory experiment that introduces the students to chemical and physical changes.
The experiments hit the HCPS III Scientific Process benchmarks. Students must create a hypothesis, make observations, as well as make inferences based on their observations.
The packet consists of five pages. The first page is the cover page of the lab, titled as, "What happens when you tell an egg a joke? It cracks up!"
The second page is the worksheet for the Egg Dying lab. In this lab, students will experiment and see whether vinegar has an effect on dying an egg brighter. On the top is a keyword reference for the students in case they forget what a hypothesis, an observation, and an inference are. Then the students must create a hypothesis that describes which egg will have the brightest color. The students then follow the procedure of the lab and then record their observations in the space given. Students then have to describe whether dying an egg is a chemical change or a physical change. Then they must create an inference based on their observations.
The third page is the Egg Sink/Float Lab which is written in a similar manner. In this lab, students will experiment and see whether eggs float in freshwater or saltwater.
The fourth page is a journal question that allows the students to extend their learning. "What do you think would happen if you dyed an egg with Kool-Aid instead of food coloring? What colors would you get? How bright would the color of the egg be?"
The fifth page has the rubrics for the lab.
