Exploring Density and Convection Through Foil and Food Coloring Investigations

In this hands-on inquiry, you'll explore the principles of density by manipulating a piece of foil to float, sink, and suspend in water without changing its mass. Document the differences in the foil configurations and describe density in your own words. Additionally, through a convection inquiry led by Mrs. Hildebrandt, observe the movement of food coloring in water, sketch the results, and discuss how this relates to Earth's internal processes. This investigation reveals key concepts in physical science and Earth science.

  1. Density Inquiry • Without changing the mass, make a piece of foil float, sink and suspend in water. • In your notebook, describe how you accomplished the task. Answer the following questions • What was the major difference of the pieces of foil? • In your own words, describe density.

  2. Convection Inquiry • After following directions from Mrs. Hildebrandt, answer the following questions in your notebook. Be sure to label and date your work! • Draw a sketch showing what happened during your investigation. • How do you explain what happened to the droplets of food coloring? • How does this activity relate to the inside of the earth?
