How Do Flowering Plants Reproduce

Young scientists explore nature's water treatment plants in this simple science demonstration. By placing a stalk of celery in a cup of water mixed with food coloring, children are able to observe how plants absorb nutrients and...

More than 200,000 invertebrate species and around 2,000 vertebrate species act as pollinators. The sixth lesson in a series of 10 encourages scholars to first identify both male and female flowering plants. Next, they bag and tag five...

A queen bee may lay between 600-1,500 eggs per day during her three to four year reign. This fact and many others are contained in a video that shows scholars how bees turn nectar from flowers into honey, traveling thousands of miles to...

Students are assigned to bring five flowers. They explore flowers to distinguish different physical features of flowers. They compare and contrast different flowers to determine what features they have in common. Students develop an...

We know plants assist in the water cycle, but how do plants get water from the ground into the air? Through a series of demonstrations or labs, scholars observe the movement of water through plants. They microscopically view the cells...

Learners think of one way to detect photosynthesis in plants besides those ways shown in class. They identify the reaction that occurs during photosynthesis. Students define the difference between an acid and a base. They identify acidic...

How do roots find nutrients? The PBS video, part of a series on food science, describes experiments proving roots grow specifically toward nutrients in the soil. A theory of how roots know in which direction to grow provides an...

Using 3D animations, pupils are given a tour of a power plant and taught the step-by-step process of burning coal to generate electricity. The animations are engaging and educational. Your young scientists will grow in their knowledge of...

Can someone really have a "biological clock"? Discover why many organisms on earth have an inherent awareness of where they are in the day's cycle.This video discusses animal adaptations, the earth's revolutions, and how light and...

Less than 25 percent of published research proves reproducible. The video discusses the importance of duplicating results, introduces the challenge related to this task, and examines the issue from multiple points of view, allowing for...
