<p class="ql-block">📌 拓展walking in the summer</p> <p class="ql-block">rose</p> <p class="ql-block">Observe the Rose</p><p class="ql-block">Look, I bought a bunch of roses from a florist. There are red rose, champagne roses and Elsa roses. Are they gorgeous? You can smell it, How does it smell?</p><p class="ql-block">S: Yes. Fragrant.</p><p class="ql-block">See, there are many sharp thorns on the stem. You can touch it with your fingertip. Be careful. Your finger hurts, right?</p><p class="ql-block">Yes.</p><p class="ql-block">So we must be careful when we hold a rose.</p><p class="ql-block">When we bought the roses from the florist, the florist used a bag to cover these thorns, and then we won't get hurt.</p> <p class="ql-block">rose and love</p><p class="ql-block">I am Venus. Venus was the Roman goddess of love and beauty.</p><p class="ql-block">You are Cupid, son of Venus. Cupid was the Roman god of desire – in one myth, he dropped nectar and the nectar bubbled up from the ground as roses.</p><p class="ql-block">Here are an arrow and a bow of love. I will give you a job. you should shoot a girl and a boy and then they will fall in love. The boy should use the roses to propose to the girl. Then they can get married.</p> <p class="ql-block">Sunflowers require eight hours of sun each day and bloom in the summer.</p><p class="ql-block">Sunflowers are “sun followers” and actually follow the sun throughout the day. This characteristic found in flowers is called heliotropism. Sunflowers will start their day facing east, the direction in which the sun rises. Throughout the day the sunflower will always be facing toward the sun. They finish their day facing west, the direction in which the sun sets. As a sunflower grows the flower gets heavy, and it doesn’t move as easily. When this happens the sunflower will always face east.</p><p class="ql-block">Sunflowers commonly have a dark brown center and shades of yellow, purples and red petals surrounding the center. The petals that surround the center are called ray florets. The dark brown center of the sunflower is actually thousands of tiny flowers. Those thousands of flowers turn into edible seeds once they are pollinated by bees and other insects.</p><p class="ql-block">Sunflower seeds are edible and are enjoyed as a snack by many people. Sunflower seeds can also be processed into butter and is a great alternative to peanut butter.</p> <p class="ql-block">Pollination</p><p class="ql-block">Flower petals are colorful because the color attracts birds, bees and other insects. The insects land in the flower and spread pollen, which helps fertilize the flowers and create seeds. </p><p class="ql-block">If a flower is going to grow, it needs for its pollen to be moved from to another plant. One way the pollen is moved is by bees. While they are dipping into a flower, some of the pollen ends up on their body and wings. When the bee visits the next flower on their hunting and gathering trip, some of the first flower’s pollen drops into this flower. Here is pollen transfer experiment helps kids to see this process happening first hand.</p><p class="ql-block">Fun Science Experiment’s Directions</p><p class="ql-block">1. Get a bee model and glue it to a stick.</p><p class="ql-block">2. Place some strips of clear plastic tape on the back off the bees’ wings and body.</p><p class="ql-block">3. set up the flowers and the pollen. use a saucer placed on the outline of a flower. Use the flour as pollen.</p><p class="ql-block">4. place a plastic mat under the flowers.</p><p class="ql-block">M: While bees are dipping into a flower, some of the pollen ends up on their body and wings. When the bee visits the next flower on their hunting and gathering trip, some of the first flower’s pollen drops into this flower.</p><p class="ql-block">As the bee moved from one flower to the next some of the pollen fell off. The pollen gets dropped into neighboring flowers. If a flower is going to grow, it needs for its pollen to be moved from to another plant.</p><p class="ql-block">We can see pollen on the bee, on the plastic mat and in the neighboring flower.When the bees fly in the air, some pollen will be left in air. It is that pollen that can cause kids with allergies to sneeze and have watery eyes.</p> <p class="ql-block">How do bees make honey?</p><p class="ql-block">They fly miles and miles to find and collect nectar.</p><p class="ql-block">Bees drink the nectar and store it in their honey stomach where enzymes start to break it down into simple sugars.</p><p class="ql-block">Once their honey stomachs are full, bees fly back to their hive and share the nectar with other bees to add more enzymes to it.</p><p class="ql-block">The bee tells other bees where to find the nectar so they can go gather more!</p><p class="ql-block">After the nectar has been shared with the other bees and the enzymes have broken it down into sugars, the newly created runny honey is put into honeycomb to be stored.</p><p class="ql-block">Bees will then fan their wings to dry out the honey. When it is dry enough they will seal it with wax so that it stays good.</p> <p class="ql-block">Nectar Collection</p><p class="ql-block">Mum: Look at the bee's tongue, It is long and shaped like a tube. The bee uses its tongue to suck up nectar like you use a straw to suck up liquids.</p><p class="ql-block">Look, I have two straws, they are long but not sharp. Now we use the straws as bee's tongue and suck up nectar.</p><p class="ql-block">I AM looking for a flower. I found the flower, so I will go back to the beehive and ask my friends to fly back to the flowers and collect the nectar. I am doing a round dance. Let's go to collect the nectar.</p><p class="ql-block">I'm going to fly to the orange flower. I have a straw-like tongue. I can suck the nectar out of the flowers, store it in my stomach and carry it to the beehive.</p><p class="ql-block">Drop the honey into the beeswax comb, which are hexagonal cells made of wax produced by the bees.</p><p class="ql-block">Come back and repeat the process until the combs are full.</p>
