So many of our flowers, fruit and vegetables need to be pollinated. Who are the pollinators and why is there so much buzz about helping bees? Check out the Bee Entomologist video to learn how the Confederated Tribes of the Umatilla are researching and caring for the pollinators of their First Foods like huckleberries and cous roots. In the Discovery Challenge video, explore what insects and other invertebrates live in your yards and school yards. Then design, build and set out bee nests for native cavity nesting bees.
This lesson introduces NGSS standards, and those standards are listed in the lesson and is part of the Explore Science Club series, an online Career Connected Learning program developed by the Greater Oregon STEM Hub. To learn more find us at: www.go-stem.org.

Students will learn about where different types of food come from, why nutrition is important, and how to grow their own food. Students will also learn the basic conditions required for plants to grow, and the importance of human action in maintaining the availability of these conditions.

The teacher leads a discussion in which students identify the physical needs of animals, and then speculate on the needs of plants. With guidance from the teacher, the students then help design an experiment that can take place in the classroom to test whether or not plants need light and water in order to grow. Sunflower seeds are planted in plastic cups, and once germinated, are exposed to different conditions. In particular, within the classroom setting it is easy to test for the effects of light versus darkness, and watered versus non-watered conditions. During exposure of the plants to these different conditions, students measure growth of the seedlings every few days using non-standard measurement. After a few weeks, they compare the growth of plants exposed to the different conditions, and make pictorial bar graphs that demonstrate these comparisons.

You couldn’t go a day without interacting with gymnosperms and angiosperms, the two most prominent groups of plants on the planet. We rely on them for food, clothing, and shelter — but why are they so common? In this episode of Crash Course Botany, we’ll find out how their seeds and flowers propelled them to evolutionary success.

Forget your favorite flowers, because we’re talking all about the mean green sporing machines. In this episode of Crash Course Botany, we'll dive into the first few branches of plants’ phylogenetic tree—bryophytes and seedless vascular plants, like mosses and ferns. These plants are the unsung heroes of the botanical world, and we’re giving them their due.

This activity is a field investigation where students gather leaves and make observation about the leaves and based on their data determine which leaves are the most common where they live.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"We investigated nutrition as a potential mechanism underlying the link between floral diversity/composition and wild bee performance. The health, resilience, and fitness of bees may be limited by a lack of nutritionally balanced larval food (pollen), influencing the entire population, even if adults are not limited nutritionally by the availability and quality of their food (mainly nectar). We hypothesized that the nutritional quality of bee larval food is indirectly connected to the species diversity of pollen provisions and is directly driven by the pollen species composition. Therefore, the accessibility of specific, nutritionally desirable key plant species for larvae might promote bee populations. Using a fully controlled feeding experiment, we simulated different pollen resources that could be available to bees in various environments, reflecting potential changes in floral species diversity and composition that could be caused by landscape changes..."
