OBIS Oil Spill
Source Institutions
In this outdoor activity, learners simulate an oil spill using popcorn (both oil and popcorn float on water), and estimate the spill's impact on the environment.
How Boulders Are Born
Source Institutions
In this activity, learners review and discuss weathering, erosion and mass wasting, to gain a stronger understanding of how Hickory Run’s Boulder Field was formed after the Laurentide Continental Glac
Nano Scavenger Hunt
Source Institutions
This is an activity (located on page 3 of PDF under Where's Nano? Activity) about identifying nanoscale objects and phenomena in today's world.
Rain Machine (Solar Still)
Source Institutions
In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.
Caterpillar Measure
Source Institutions
In this activity, young learners use different-sized paper 'caterpillars' and various household items to predict and measure their height.
Floodplain Modeling
In this design-based lesson, learners study flood dynamics as they modify a riverbed with blockages or levees to simulate real-world scenarios.
Work Up An Appetite
Source Institutions
In this activity, learners participate in fun movement activities while playing on a giant game board. Use this activity to get learners involved in physical activity.
Number Patterns
Source Institutions
In this lesson, learners are challenged to discover the relationship among six numbers.
Dinosaur Breath
Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.
Modeling an HIV Particle
Source Institutions
This activity helps learners visualize the Human Immunodeficiency Virus (HIV) by constructing three-dimensional HIV particle models from paper.
Moving Without Wheels
In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.
Working with Watermills
Source Institutions
In this activity, learners explore how watermills have helped harness energy from water through the ages.
Catch a Wave: How Waves are Formed
Source Institutions
In this three-part activity, learners explore how waves are formed and why some waves are bigger than others. First, learners observe waves of water in a pan generated by an electric fan.
Inner Strength
Source Institutions
In this activity about endoskeletons (page 8 of PDF), learners observe, compare and contrast different kinds of chicken bones, and relate their chicken bone observations to human bones.
Nano Waterproofing
Source Institutions
This lesson focuses on how nanotechnology has impacted the design and engineering of many everyday items from paint to fabrics.
Safe Food Preparation
Source Institutions
In this activity about food safety and nutrition, learners investigate safe food preparation by making fruit ice cream.
What Color is Your Air Today?
Learners develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper or online.
Food Webs
Source Institutions
In this activity, learners construct possible food webs for six different ecosystems as they learn about the roles of different kinds of living organisms.
Diatom Ooze: Ooze Clues
Source Institutions
In this activity, learners will plot the distribution of various oozes using information from sediment maps.
Number Sense and Computation: Food For Thought
Source Institutions
In this math lesson, learners identify and compare unit costs of given items. Learners use computation skills, problem solving and number sense to find the cost of an ounce of cereal.
