DIY Science Kits


kids participating in a mosquito habitat class at the library

Mosquitoes are a problem! Contribute to the health of your community by finding and reporting potential mosquito breeding habitats around your home and neighborhood.

Our city lights up at night, which is not good for the environment. Help scientists study the impact of “light pollution” on the climate, animal migration, our health, and more.


kids participating in a cloud identification class outside the library

Scientists study clouds to understand the earth’s weather and climate. Satellites see only the tops of clouds, so scientists need you to tell them what the clouds look like from underneath.

A healthy ecosystem has lots of different kinds of plants and animals. Share photos and information about the species living in your community with scientists around the world.


teens participating in a water transparency exercise by the LA River

Lots of different things affect water quality. Collect and share information on the pH, electrical conductivity, Total Dissolved Solids (TDS), and temperature of nearby rivers, ponds, and tap water to help scientists understand how climate change and water quality are linked.

Monitoring air quality in your neighborhood identifies areas where pollution is a problem and helps researchers find solutions.
