In its simplest terms, pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma, i.e., fertilization. It’s a demonstration of “the birds and the bees and the flowers and the trees” working in perfect harmony to complete the circle of life.
Without hesitation, your students will be attracted to lessons on pollination. Your classroom will be all abuzz once they discover that:
- animals pollinate more than 75% of the 1,300 types of plants grown worldwide for food, medicines, & fabric; 1
- more than one out of three bites of food we eat or beverages we drink are a direct result of pollination; indirectly, pollination plays a role in most of what we eat and consume.
Yes, at first, students may assume you’ll simply drone on and on about the critical role bees play in pollination. And while bees ARE the bomb, other creatures such as butterflies, moths, birds, bats, beetles, ants, and even small animals also do their fair share to support pollination.
The black-and-white ruffed lemur is the largest pollinator in the world!
Now, if you really want to drop the mic after your lesson, explain to your class how electromagnetic forces (EMFs), i.e., biomagnetism plays a role in pollination. There are two ways this is shown:
- By plants. Studies suggest that biomagnetism emanates from selective flower parts and in the presence of iron deposits in the antenna and joints of ant pollinators during the plant’s reproductive cycle.2 The researchers believe that biomagnetism plays a signaling role in the attraction between flowers and pollinators.
- By pollinators. Honeybees and some other pollinators have a magnetoreception sense similar to fish, whales, and dolphins.3 That’s the sense birds and butterflies use to help them stay oriented during migrations. It’s another one of their many superpowers! With their magnetoreception, these amazing creatures can perceive the Earth's magnetic field (MF), helping them navigate the route between the plants and their hive
Bam! Mic drop.
Did you know? Researchers are investigating whether the honeybee's compass abilities could suffer from the “radio frequency (RF) smog” produced by modern civilization4 (e.g., wireless technology such as cell phones, cell phone towers, Wi-Fi, and wireless water meters).
Students are naturally drawn to the busy world of bees, butterflies, and other animals that do the vital work of moving pollen around. Encourage their natural passion for this concept with your lesson plans.
