Revised “Understanding Nutrition” Activity
Students evaluate their current food choices. In this health science lesson, students test different drinks to rate the amount of Vitamin C content. They discuss results in class.
Curated OER
Let's Settle It!
Students investigate and record data about sedimentation rates. They make a sedimentation bottle using aquarium gravel, sand and potting soil. They discuss the sedimentation rates that they see in their bottles.
What affects Frog metamorphosis?
In this lab, students explore pollutants which affect frog metamorphosis using household pollutants (vinegar, oil, and bleach) and sponge capsules.
Curated OER
Earth Day
Students participate in activities that familiarize them with what Earth Day is, why it is important, and why it is a celebration.
What happened to the frogs?
Students will select ten rubber frogs and determine their pollutant source based on their malformations. Students will write a brief essay on their findings. Students will be engaged in the lesson the entire time!
