STRUCTURES OF LIFE—Investigation 2, Part 2: Life Cycle of the Bean Complete Teacher Notes

Investigation 2, Part 2 Plant Needs What do plants need to survive? • IG pg. 156, Step 1

Investigation 2, Part 2 Bean-Plant Growth 50 cm 40 cm 30 cm 20 cm 10 cm Week 1 Week 2 Week 3 Week 4 Week 5 Week 6 Week 7 Week 8 Date Date IG pg. 156– 158, Steps 2– 7

Investigation 2, Part 2 Plant Life Cycle What happened to the flowers? What did you find inside the bean pods? Have you seen beans like these before? What do you think would happen if we put these seeds in a sprouter? If the seeds sprouted, what kind of plant would grow? If those plants made seeds, what kind of seeds would they produce? IG pg. 159, Steps 8– 9

Investigation 2, Part 2 Focus Question Now that we have bean seeds on our adult bean plants, the bean story is right back where it started. We have bean seeds we can plant to grow some new bean plants. We have observed the complete life cycle of bean plants. What is the sequence of the bean plant's life cycle? IG pg. 159– 160, Steps 9– 12

Investigation 2, Part 2 Bean Life Cycle

Investigation 2, Part 2 Other Life Cycles What does inherit mean? Why don't all of the bean plants look the same if they inherit the same information? Describe the life cycles of some of the fruits you dissected in Investigation 1. What else goes through a life cycle? Describe the cycle. IG pg. 160– 161, Steps 13– 15

Investigation 2, Part 2 Vocabulary Review hydroponics a technique of growing plants (without soil) in water containing dissolved nutrients nutrient a material needed by a living organism to help it grow and develop flower a plant structure that grows into fruit adult an organism that is fully developed life cycle the sequence of changes an organism goes through IG pg. 161, Step 16

Investigation 2, Part 2 Reading in Science Resources Investigation 2: Growing Further Germination …………. . ………………… 22 Life Cycles ……………. . ………………… 26 IG pg. 162– 163, Steps 17– 20

Investigation 2, Part 2 Wrap-Up/Warm-Up What is the sequence of the bean plant's life cycle? Pair up with a partner to • share your answer to the focus question; • compare your bean-plant life-cycle drawings. What patterns do you notice in the life cycles of the organisms we have observed and read about? How does your bean-plant life-cycle drawing help you predict what stages other plants might go through in their life cycles? How does your bean-plant life-cycle drawing help you predict what stages animals might go through in their life cycles? IG pg. 163, Steps 21– 22
