STEM Gems are short discovery-based experiences. They involve little or no materials and may be easily implemented by educators who are not STEM specialists. Each STEM Gem is designed to engage young people in active experiential learning. The activities begin by setting up connections to prior knowledge, then a hands on activity provides new concepts and the opportunity to design experiments to answer any questions the kids discover. Finally, a connection to a different scenario for the concept is provided to help cement and evaluate the learning.

STEM Gems are experiences designed to be used with kids of all ages. Younger children should be focused on one idea or concept and should perform the activity as a collective group with prompts and directions from the teacher. With older youth, the teacher should act as a facilitator. The older youth should be set up to work independently in small teams and encouraged to ask questions and try out their own experiments to answer them. Each team should report back on their findings, so a consensus around the concept is reached.

Each STEM Gem is presented in an easy to follow lesson plan:

STEMGems-CloudinBottle-1Cloud in a Bottle
Download | View Andy the Science Wiz's Video About Cloud in a Bottle

The sun directly affects the weather outside our window. Each day the weather changes, as do the clouds in the sky. Have you or your students ever wondered how clouds are formed, or what accounts for their different shapes and sizes?

The sun's heat changes the temperature, causing water to evaporate and air to move from place to place. Water from lakes, rivers and oceans is soaked up into the air. As the air cools, the water it was carrying condenses and clouds are formed. By using hot water, ice and a soda bottle, your students could create a cloud in a bottle—a tangible way to better understand this scientific, weather-based principle!

 

STEMGems-CartesianDiver-1Cartesian Diver
Download

Long, long ago an ancient Greek scientist noticed that when he sat in his bathtub, the water overflowed. It was at that moment that Archimedes' Principle was born. This principle states, "An object immersed in water will experience an upward, buoyant force equal to the weight of the water it displaces." Your afterschool students can demonstrate this ancient principle by using a modern day soda bottle to create a Cartesian Diver.

Cartesian Divers demonstrate the concepts of air pressure, buoyancy and density through the use of bubbles and pressure. Students will note entirely different reactions are caused when they either squeeze or release their Cartesian Diver. Once your afterschool students learn these concepts, they will understand how scuba divers and submarines float and sink, just like their Cartesian Diver.

Plants are incredibly important to Earth's ecosystem. They have been oxygenating our planet for millions of years. Most plants grow from seeds. Once sprouted, plants use the chemical process of photosynthesis to create their own food. Spring is the perfect time to teach your afterschool students about the growth process of this all-important flora.

Using simple household supplies and some grass seeds, your students could make their own miniature inflatable greenhouses. As the seeds start to germinate, your afterschool students will see science at work. And in seven days, they will have grown a small putting green.

 

STEMGems-Elephant-CoverHow to Weigh an Elephant
