Testing Bangladesh's Waters

Will this water source support life? Small groups test the chemistry of the water drawn from two different sources. They then compare the collected data to acceptable levels to draw conclusions about the health of the source. The...

From their sweat to the water vapor in their breath, astronauts recycle every possible drop of water while in space. After watching a short video describing the different ways materials are recycled and reused in space shuttles, young...

Should you trust the water you drink every day? The hands-on activity has scholars test water from different sources for contaminants. Pupils perform chemical testing and make conclusions about pH, hardness, iron, chlorine, lead, and...

How do you prevent the spread of water-borne illness in large public swimming areas? Scholars discover the challenges to identifying safe water through an inquiry experiment. They then produce posters sharing their understanding of water...

Environmentalists test stream water for temperature, pH, and turbidity. Each group shares their information and then the class makes an overall evaluation of the water quality. A slide show sets the backdrop for the teaching portion and...

Bubble, bubble, boil and trouble! What causes common substances like baking soda and vinegar to react the way they do? Welcome your junior chemists to the wonders of acid-base chemistry using a comprehensive and fun resource. Engage them...

How important is water quality where you live? The first module in a six-unit series includes four lessons on water quality. By applying the concept directly to the lives of pupils, they engage in meaningful learning. They read about...

Give young scientists a new appreciation of fresh, clean drinking water. After learning about the ways astronauts recycle their air and water, your class will work in small groups creating and testing their very own water filtration...

Young scholars investigate the water cycle by performing a simple hands-on activity using a plastic container, plastic cup, a rock, and a reflector lamp. They observe the model and measure the water level from time to time.

Take your class to the nearest local lake, creek, or pond to assess the quality of the water, both biologically and chemically. Instructions are provided for how to collect invertebrate samples, but you will need to familiarize yourself...
