Diffusion Lab: Investigate the Spread of Food Coloring with K/1st Grade
Diffusion Lab: Investigate Food Color Diffusion with 2nd/3rd Grade
Diffusion Lab: Investigate the Rate of Diffusion with 4th/5th Grade
Diffusion Lab: Investigate the Rate of Diffusion with 6th/7th/8th Grade
Supplies Needed: Beakers or heat proof container, food coloring, stop watch, water.
Students will test the effects of temperature on food coloring diffusion. Uses Simple supplies to help students see that molecules are moving. Students will test cold, room temperature, warm, and hot water depending on grade level. They will learn how to rank their observations. The science journal helps students learn the scientific method and how to write a report. They will record observations, graph, summarize, write a conclusion, and list possible errors.
Teachers will love the step by step directions and journal layout. Students will enjoy seeing the food coloring swirl. This is a great activity for science fairs, classrooms, clubs, or science camps. Great for teaching multiple abilities at one time.
