Cleaning with DirtAdd to list Details
Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.
Create 3D glasses and use them to explore color, light and optics. Fool your brain into 'seeing' three dimensions on a flat surface!
Straining Out the Dirt
Learners take on the role of environmental engineers as they design water filters.
Clean Water: Is It Drinkable?
In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.
Exploring the Universe: Filtered Light
"Exploring the Universe: Filtered Light" demonstrates how scientists can use telescopes and other tools to capture and filter different energies of light to study the universe.
Wetland Filter Model
In this quick activity (located on page 2 of the PDF under GPS Wetlands Activity), learners will model how wetlands act as natural filters for the environment.
In this activity, learners explore how engineering has developed various means to remove impurities from water.
Radial ChromatographyAdd to list Details
How many colors make black? Gather as many water soluble black markers as you can find.
Dye DetectiveAdd to list Details
Learners analyze mixtures of dyes using filter paper chromatography. They place spots of the different dyes at the bottom of a piece of filter paper, and hang the paper to touch the surface of water.
FilteringAdd to list Details
Make a quick and easy filter from household materials. A filter will catch any solids suspended in a liquid and filter them out. By using a filter, learners can discover amazing things.
Light and Sound
In this four-part activity, learners explore light and sound through a variety of hands-on investigations.
In this activity, learners interact with whale artifacts such as replicas of skulls, bones, teeth, and baleen (hair-like plates that form a feeding filter).
In this activity, learners use gelatin as a lens to investigate the properties of laser light.
Let's Bag It
Learners observe and discuss a vacuum cleaner as a model of a baghouse, a device used in cleaning industrial air pollution.
Water treatment on a large scale enables the supply of clean drinking water to communities.
Giving Water the Treatment
In this ecology activity (page 8 of the PDF), learners explore how to filter contaminated water using a variety of materials.
