Write some suggestions about some measures to protect bees. Make a poster about protecting bees and display it in the classroom. $Bees communicate the location of food through a figure eight movement called the wagon dance. The angle of the dance relative to the sun shows the direction of the food. The length of the vehicle shows how far the food sources. But that's not all. Did you know bees have five eyes, and they beat their wings very fast, about two hundred times per second. This makes that famous buzzing sound. These little insects are truly full of big surprises. Reading the busy being, ever wondered who helped make the food you eat? The answer buzz bugs like me. And not just talking about honey, although we make that yummy runny stuff too. Think brockley, tomatoes, apples. In fact, bees help provide about a third of what you eat, as well as bringing your gardens to life. We do this by spreading poland between different parts of flowers and plants, allow them to grow seeds and fruit, or while flapping our wings two hundred times per second. In the U. K. There are over two hundred and fifty species made up of honey, solo tree and bubbies. But right now we're in serious trouble. In the last ten years, our U. K. Population has shrunk by around the third. That's because our habitat of being destroyed, these changes in the climate and some hives are being attacked by viruses. Chemicals used to protect crop from the insects of what have been blamed for some U. K. Species haven't disappeared completely. And it's not just here. The us. Recently added seven types of b to its list of endangered species. But humans are taking action to help us survive, because if we're not here to help make your vegetables and fruit grow, you guys could find yourselves various that he situations. It's finally spring. The flowers are blooming, the leaves on trees are coming back, the birds are singing their morning songs, and the butterflies and bees are buzzing from flower to flower. Today we are going to talk about pollination. Who are the pollinators? Birds, bats, butterflies, moth flies, beetles, wasps, small animals and most importantly, bees are pollinators. They visit flowers to drink, sector or feed off polin and transport polling Green as they move from spot to spot. Nectar is a mixture of water and sugar that plants produce to attract pollination. All flowers have a male park called the answer and a female part called the stigma. Pollen is a powdery stance that comes from the male, and when pollinators move from one flower to another, the polin attaches to their bodies and goes to other flowers. This makes IT possible for plans to make seeds and reproduce. Pollination is necessary for food production. All of our plant based foods, including grains, fruit and vegetable, need pollination. All of our animal based foods like meat, eggs and milk, also needed because these animals eat plants too. IT is so important that plants have evolved over time to have bright, colorful flowers or delicious sense just to attract pollination. If we didn't have flowers, we wouldn't have food at all. Talk about flower power. Some of the most common pollinators are bees, butterflies and hummingbirds. If you can keep an eye for all the pollinators you see, if you plant flowers, this will also help feed the bees, birds and butterflies. Keep an eye for your favorite flowers and enjoy this lovely spring. We can't live without bees. Imagine you go to the supermarket in your area, but there are almost no fruits, vegetables, honey, milk, eggs or chocolate. How would you feel? Disappointed, angry, sad. At this moment, you realize people, plants and animals are all connected. We need each other to live, and bees are one of the best examples of this connection. Bees are very hardworking animals, and their greatest work is pollination. On one trip, they often visit fifty to one hundred flowers. As they fly from one flower to another, they take pollen with them. This action helps plants grow. In fact, without their work, about eighty percent of the plants in the world cannot grow. For this reason, many scientists believe that bees are the most important animals on this planets. Bees are also one of the most interesting animals in the world. For example, they work hard together to make their homes in order to store honey. They create honey comes. Another interesting thing about bees is how they communicate. When a bee finds new food, IT uses a dance to tell the others where and how far away the food is. Bees play an important part in the ecosystem of our planet. However, the number of these is dropping, and scientists are worried. Bees need our help. And there is a lot we can do. Think about what you can do to protect one of the most amazing animals on earth. nullAre you one of those people who hate these little crawling things? Or maybe these ones with the stingers crew you out more? Have you ever wish that all the insects would just die out? Picnics would be much more pleasant? And so what gardening could the world become a Better place if insects disappeared? Or would this have terrible consequences? Not obvious for us at first baLance. This is what if, and here's what would happen if all the insects disappeared from the planet. If you think bugs only exist to give you the creeps and the chew on the letters in your garden, you're wrong. Well, not totally wrong. Some of them are, in fact, meant to destroy crops, give you skin irritations in addition to painful stings, and even worse, spread diseases like zek a and malaria. But ninety percent of them are not only harmless, but beneficial to us under the planet. They say, without insects, the world would fall apart. Just how bad would that be? If we put all the insects on the planet together on a scale, they would wait approximate three hundred times more than all humans combined. If you have a sector, however, you probably want me to stop right here, just let me add that the ants alone would wait more than all humans. If our planet suddenly had all this weight off its shoulders, farmers would be the first to celebrate. They no longer need to poor chemicals on their crops to save the harvest from hunger pests. But that celebration wouldn't last long, because without insects we'd all start pretty fast. And no, we don't mean that those bold adventures who snack on crickets and grasshoppers somewhere in thailand with starve humans might be predators in the food chain, but insects are the ones to hold this chain together. They are food for some reptiles, small birds and frogs. If all insects vanished, those animals would seize to exist to the animals. Feeding on frogs and raptors would be the next die off. And then the ones further up the chain, eventually this disruption would work its way up to think you could survive by going vegan. Wrong again, eighty percent of all planet life on the planet is made up a flowering plants, meaning they require pollination to reproduce. Insects are the ones who make this happen by physically transfering pollen from a male answer to a female stigma. You can argue the birds and bats, even wind, can pollinate too. But most of the work is done by bees, wasps, moths, butterflies and flies without them. It's game over for most plans, depending on what your food preferences are. Fifty ninety percent of your diet comes from those flowering plants. There would be no fruit, no vegetables, no rice and no weed. This also means no food for cows, chickens, most fresh water, fish and all the animals. Wee humanity IT doesn't matter if you, your vegetarian or a meat lover, if the insects disappeared, you'd have no chance of long term survival. You'll be left to slowly starve on a planet heap, ed up with piles of organic waste. Because not only do insects feed small animals and pollinate plants, they're also major d composers of dead stuff, from leaves to corpses. That wouldn't be the world you'd want to live in. And to be honest, not all the insects are gross looking, wouldn't agree. Join us next time on what if. In the UK, there are over two hundred and fifty species made up of honey, solo tree and bombo bees. But right now we're in serious trouble. In the last ten years, our U. K. Population has shrunk by around a third. That's because our habitats of being destroy these changes in the climate, and some hives are being attacked by viruses. Chemicals used to protect crops from the insects of water being blamed for some U. K. Species haven't . disappeared completely. And it's not just here. The us. Recently added seven types of b to its list of endangered species. But humans are taking action to help us survive, because if we're not here to help make your vegetables and fruit grow, you guys could find yourself very different situations. Seventeen and interesting facts about bees. Number one, the bees beat their wings eleven thousand four hundred times in one minute. Number two, honey bees are flying at a speed of around twenty five kilometers per hour and beat their wings two hundred times per second. Number three, honeybees live in hives. Honeybees are divided into three types, queen workers, female be, drones, male be. Number four, queen bees to lay the eggs that will spend the hive's next generation of bees. Queen b also produces chemicals that guide the behavior of the other bees. Number five, workers, we are.

Number fifteen, the queen bees busiest in the summer months, when he can lay up to two thousand, five hundred is a day. Number sixteen, only female bees can stay. Male bees don't have stingers. Number seventeen, these are insects, so they have six legs. nullImagine you go to the supermarket in your area, but there are almost no fruits, vegetables, honey, milk, eggs or chocolate. How would you feel? Disappointed, angry, sad. At this moment, you realize people, plants and animals are all connected. We need each other to live, and bees are one of the best examples of this connection. Bees are very hard working animals, and their greatest work is pollination. On one trip, they often visit fifty to one hundred flowers. As they fly from one flower to another, they take pollen with them. This action helps plants grow.

Think about what you can do to protect one of the most amazing animals on earth. The three fix is the begin the thing. Let's think about the, say, the world. nullHi, we are bees.
