At Home for Earth Day: Make a Water Filter

Use common materials from your home and yard to make a basic water filter, and watch it work on muddy water!

Filtration is the process of separating solids from fluids using a a filter—a medium that only the fluid can pass through, leaving the solids “trapped” behind. Natural and human-made filters are all around us: paper filters keep coffee grounds out of freshly brewed coffee; HEPA filters capture dust particles in our vacuum cleaners; our kidneys even act as filters to remove harmful materials from our blood! In nature, dirt is naturally filtered out of water as the water moves through sand, soil, gravel. This is the process that we will be demonstrating today.

At Home for Earth Day: Plastic Bottle Terrarium

A terrarium is an enclosed environment created for plants, which needs very little outside intervention once it is set up. In celebration of Earth Day, let’s create a basic terrarium from an upcycled 2-liter plastic bottle. When it is complete, our plant will receive sunlight through the transparent walls of the bottle, and it will obtain water from its own water cycle!

At-Home STEM Activities: Ice Cube Race

Learn how different colors interact with heat in this simple solar-powered activity!

This activity is geared toward elementary-level learners, but can easily scale up or down depending on existing science knowledge. Younger children may appreciate performing the experiment with less emphasis on the background and concluding information, while older students may choose to supplement this lesson with in-depth research on wavelengths and energy.
