The media for presidential imagery has ranged everywhere from the traditional oil-on-canvas and marble to cotton handkerchiefs and sewing-box lids, and the Gallery houses today a richly varied array of presidential likenesses. In the selection of portraits on view here, some are more sophisticated and striking than others; some are quite rare or altogether unique; some are calculated to impress us with their gravity while others are warmly intimate. Taken collectively, however, they all have one
You Be the Conservator
This web activity, recommended for grades 5 and up, is designed to teach both content and process.

California has always been a place of cultural interaction. Early California evolved and changed with each new group of settlers. These images depict the developing interconnectedness of California's early cultures. They also underscore the importance of movement and later settlement of peoples in California. Some of the modern images underscore the contested and often romanticized nature of California’s Spanish and Mexican heritage. This is a collection of primary source images.

Cacti are often overlooked as flowering plants. In fact, cacti bloom with colorful flowers and reproduce like all other angiosperms.
Bee on flower
Bees visit flowering plants to collect nectar so they can store it as honey back at their hives. As a bee visits one flower after another, pollen collects on its entire body and especially on the legs. Bees help pollinate flowers while they collect nectar. This is a mutualistic behavior.
