The development of the male and female gametes in a plant is illustrated, explaining plant fertilization, pollination, and reproduction. Overall, get a complete picture of the life cycle of a flowering plant with some wonderful details...

The pollination of milkweed involves a high risk for the bees and butterflies involved. Though the nectar is sweet and delicious, the pollen is very sticky. If a bee is not strong enough to pull the pollen free, he will be stuck and die....

With Nancy Odell's help, students learn what pollination means. She interviews a bee and a flower to ask them to describe pollination. A bee then talks about how he takes pollen from one flower to another. It's a creative way to discuss...

See what the buzz is all about! A short video details what it is like to be an agricultural inspector who specialized in apiaries. 

A plant engaged in sexual deception? Strange but true. Believe it or not, orchids have developed a range of sexual adaptations that permit them to attract pollinators. The narrator of a short video describes a variety of strategies used...

What's the difference between seasonal allergies and seasonal colds? Learn about one of the most common seasonal allergies, ragweed, through a brief yet informative video as part of the Seasonal Science series. Understand why ragweed is...

More than 125 species of pine trees exist, and each species can live over 100 years, with some living over 1,000 years—that's a lot of pine pollen! The Seasonal Science series explains why pine trees produce pollen. The video details the...

Allergies are really just mistakes our immune system makes—and we pay the itchy, watery price! An ACS Reactions lesson outlines the immune response to pollens and other allergens. When the body mistakes these allergens for germs, it...

Despite the title, here is a video that makes honey even sweeter! Biology scholars journey inside a beehive with a fascinating video from the American Chemical Society's Reactions playlist. Pupils learn about the social structure of a...

What triggers asthma? What are the symptoms of an asthma attack? Watch a video that explains how asthma affects the respiratory system and the extra work the lungs have to do when a person is undergoing an asthma attack.

Bees play a crucial role in pollination. In fact, without bees, a lot of fruits and vegetables would not exist if it weren't for bees. Watch a video that explains and demonstrates how bees pollinate plants.

Not everyone looks forward to the spring, because it means allergy season for some. An informative video takes a deeper look into what happens to the immune system when seasonal allergens attack.

"With the declining numbers of bees, the cost of over 130 fruit and vegetable crops that we rely on for food is going up in price." While scientist Noah Wilson-Rich uses the plight of honey bees as the main focus of his...

It's that time of season again! The wind is adrift and allergies are in the air. Check out this video about allergies to teach your students what to do in case of allergic reactions.

Beautiful high-definition video footage by Louie Schwartzberg captures the flights of hummingbirds, butterflies, and bees up close. Fruits ripen with time-lapse photography and flowers bloom as these animals, along with bats, seek food...

Bees are the best! Learn about the life cycle of honey bees, their history, and how important they are to our environment. A professional honey bee keeper describes the metamorphosis, hive construction, and life cycle of the bee. A very...

Filmed like a teaser trailer for a dramatic movie, this clip showcases the adaptations of pollination and bees. Lady Bee flies from flower to flower while intermittent descriptions of her actions are highlighted. This is very cute.

Hone in on the honeybee and learn how you can help these important pollinators from going extinct. Honeybees play an important role in plant growth; encourage your young biologists and environmentalists to see the significance of these...

Pollen starts to dry out when it leaves the flower, which can destroy the genetic material the grain is carrying. To combat dehydration, pollen grains have evolved a way of folding up to prevent water from leaking out. Eleni Katifori and...
