Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. What do plants need to survive? Plants need space, air, and ideal temperatures . 2. How do plants reproduce? Plants reproduce through asexual for sexual reproduction. In asexual reproduction it's done through the roots stems and even the leaves on the plant itself , but through sexual reproduction there's a Fusion between Bell and female gamuts in the specific plan. Gizmo Warm-up Several common vegetables, including Bok choy, napa cabbage, and turnips, are varieties of a plant called Brassica rapa. Fast plants are a rapid-cycling variety of Brassica rapa that was developed at the University of Wisconsin. These plants have short growing cycles and are ideal for classroom use. In the Fast Plants® 1 – Growth and Genetics Gizmo, you will learn about the life cycle and genetic traits of Fast Plants. In the Gizmo, drag seed packet A to container 1 and seed packet B to container 2. Click Play ( ), and then Pause ( ) after about 10 simulated days. 1. A plants traits are its characteristics. Drag the magnifying glass over container 1. Describe the traits of these plants. The plants traits is the green and yellow pigment I'm not it's very tall and skinny. 2019 2. Drag the magnifier over container 2. How do these plants differ from the container 1 plants? In container 1 the plant was much smaller then in container 2 in container too the plant had a brownish color rather than green the leaves were also much larger than in container one 2019 Activity A: The Fast Plants® life cycle Get the Gizmo ready:  Click Reset ( ). Plant seeds A in container 1.  Turn on Show hints. Introduction: Fast Plants® are grown in wicking systems, typically made of nested plastic containers. The larger container is the water reservoir. Water from the reservoir travels through the wick into the soil, where roots draw the water into stems and leaves. Question: How do Fast Plants grow and reproduce? 1. Grow : With seeds A in container 1, click Play. Click Pause on day 17. A. Is the container full of water? no If not, drag the water bottle to the container. B. Do the plants look like they are too crowded? yes If so, use the tweezers to pull out a few plants and discard them in the waste hole. 2. Pollinate : The bee stick should be active at the bottom of the Gizmo. A bee stick is a dead bee glued on a toothpick. Drag the bee stick through the flowers. A. What happens to the appearance of the bee stick as it is dragged through the flowers? The flowers turn to an orange color The bee’s hairy thorax (middle section) is covered in pollen. Pollen is produced by male reproductive organs in the flower. Each grain of pollen contains a sperm cell. B. What happens to the flowers? The peatal on the flowers were orange The orange color represents flowers that are pollinated, or fertilized. (In reality, pollinated flowers do not turn orange. This is done to show pollination in the Gizmo.) 3. Grow : Turn on Auto-watering. This will keep the containers full of water automatically. Click Play, and then Pause around day 24. Use the magnifier to observe the plants. A. What do you notice happening at the top of the plants? The petals began to turn back into a yellow color when they started to fall off the planet , an the stem was getting smaller Pollinated flowers develop into long, thin seedpods.
