Experiment 3- See how a plant grows
Life cycle of a bean plant
All seeds have three parts, a seed coat which protects the inside of the seed, food for the plant to grow (endosperm), and a baby plant (embryo). The seed usually begins to develop when it is exposed to water. The water swells the embryo and bursts the seed coat. During the earliest phase of growth, when the embryo has no leaves and can't perform photosynthesis, the endosperm serves as a food source. In this scientific experiment, elementary teachers can lead students through a few simple steps to help them understand how plants begin and that they need sunlight, water, soil, and air to grow.
Mini-Lesson and Standards: This mini lesson plan focuses on seeds and how they germinate. The lesson plan is for 3rd grade and it includes a book by Eric Carle and a video clip from brainpop.com*Click Here> Mini-Lesson and Standards
So Lets Review! Where do plants come from? Plants come from seeds. Each seed, when exposed to the right conditions, begins to grown into a plant. A plant needs several things to help it germinate and begin to grow. It needs soil, water, and warmth. Click here for more information.> More Info
