Understanding Waves
Students examine the physical properties of waves to explore the word crest and trough. They use toys to study waves in air, water and light.
Curated OER
"Mummies--The Great Cover Up"
Young scholars wrap their mummy, use canopic-style jars for the preserved chicken organs and design and decorate a sarcophagus. They collect data by weighing, measuring and graphing their "mummy" and its organs.

4.5: Exploring Uses of Rocks & Minerals
Students, in pairs, use observation skills to identify objects from the past and present in our environment made of rocks and minerals of Illinois.
Curated OER
Where's My Mummy: Preservation Techniques
To observe preservation techniques firsthand, learners dry a flower in sand and compare cucumber slices soaked in salt water for a week with slices left out to dry in the open air. Video resources (not attached) include one about mummies...
Curated OER
Land Use Issues
Students examine soil types and determine the ability of each to absorb water. Working in groups, they time how long it takes for water to seep out the bottom of the cups. They examine soil components, conservation, erosion, and tree...
Curated OER
Exploring How Rocks Are Formed
Learners examine the three types of rocks. They discover the processes that occur so each type of rock can be formed. They participate in activities to help them see how rocks are formed.
Curated OER
Worms, Nature's Recyclers!
Students study what worms need to survive in different environments. They study how worm composting improves soil and reduce waste. They discuss composting techniques and present a puppet show about a worm's life.
