An Apeeling Problem
In this Laying the Foundation video lesson, students use oranges, string, cardstock, and compasses to discover the formula for the surface area of a sphere. By measuring the radius of the orange and using the formula for the area of a circle, students are able to determine the surface area of the sphere. Through this hands-on experiment, students are more likely to remember the formula for surface area and understand how it applies to real-world objects. The lesson also emphasizes the importance of identifying potential errors in experiments.
Through this Laying the Foundation video lesson, students will discover the formula for the surface area of the sphere. Materials needed for this activity include oranges, string, cardstock, and compasses.
Laying the Foundation, a division of the National Math and Science Initiative, is a professional development program focused on improving college readiness through teacher training and rigorous classroom-ready resources. We also provide teacher mentoring, administrator workshops, and curriculum implementation services. Training packages can be customized to suit your needs as a school or district.

Staff Review
This video is good for giving you an idea of how you might lead an activity for students to discover the surface area of a sphere by using an orange, taking measurements, and taking the peel off. This is a very creative way to lead students to a discovery of this geometry formula.
