2 Plant Lesson # 1 (Introducing the Topic: Importance of Plants) Grade: 2 Materials: Bits That Grow Big (By: Irma Webber) School s lunch menu Plant Journal (p. 1 ~ Pretest, p. 2 Lunch menu activity) Worksheet: How Can We Use Plants? Content Standard(s): Earth Sciences: Students know rock, water, plants, and soil provide many resources, including food, fuel, and building materials, that humans use. Student Objective: Given examples of how plants are used on a daily basis, students will be able to recognize the importance of plants. Given a worksheet on the use of plants, students will be able to identify how plants are used for food as well as other ways (to build houses, furniture, etc). Anticipatory Set: Boys and girls, we are going to begin our plant unit today, and as we explore the exiting world of plants, you will all become wonderful plant detectives. Are you ready? This is our class plant, Plato. Plato will be with us throughout this entire unit. What kind of plant do you think he is? Allow time for students to observe and respond. Plato is a tomato plant, and he needs lots of good care. In order for us to take care of him, we ll need to learn how to. Purpose: Throughout this unit, we ll be learning many different things about plants, including where they come from, how they grow, and why they re important. We will be doing several experiments to help us figure out how plants work.

3 Input: Pass out observation journals. Everyday, we will be working from your plant journals. Go ahead and write your name on your journal. To help us figure out where plants come from, I m going to read you a section from this book, Bits That Grow Big, by Irma Webber. Read the first line on p. 5, Plants are important to people. Ask, Why do you think plants are important to people? Ask the students to open their plant journal to p. 1 and write down their answers. Then call on some students to share. Continue reading up to p. 7. As a teacher, I want to know what you already know about plants, so I know what it is I need to teach you. Take a look at the questions on p. 1. (Read them to the students). This is a pretest, so I want you to try your best to answer those questions. There should be no talking until everybody is done, and I ll know that once you close your journal. Modeling: Let s review that section we just read from Bits That Grow Big. Who can tell me on thing that plants are used for? Allow every child to answer. We are going to do an activity today where you will be looking at this week s lunch menu and you ll be tracing the source of ingredients to plants. Do Monday s menu together with the class. Now I want you to be Plant Detectives and link as many ingredients you to can to plants for Tuesday-Thursday s menu. You will do this in pairs. (Assign 1 day to each pair). Check for Understanding: Does anybody have any questions? Does everybody understand what we re doing? Guided Practice: Once the students are done, ask each pair to share their answers. Allow other students to pull out any other ingredients they may find that link to plants. Independent Practice: Now that we know how important plants are, let s see if you can match the ways we use plants other than for food. Pass out the How We Use Plants worksheet and explain the directions to the students. Closure: Who can tell me why plants are so important? Later on tonight when you eat dinner, I want you to continue to think about the importance of plants, and I want

4 you to trace the ingredients of your dinner to plants. You can share your findings with me tomorrow as we explore the question, Where do plants come from?

5 Plant Lesson # 2 (Seeds) Grade: 2 Materials: 8 dry lima bean seeds & 8 soaked lima bean seeds (in water) Journal Worksheet p. 4 Experiment 2 (Do Seeds Need Air to Grow?) 3 jars & spoons Potting soil 12 Lima bean seeds Experiment 3 (Does Temperature Affect Seed Growing?) 2 mugs w/ saucer covers 8 cotton balls 6 lima bean seeds Experiment 4 (Can Plants Grow Normally in the Dark?) 2 flowering pots Potting soil Lima bean seeds Content Standard(s): Earth Sciences: Students know rock, water, plants, and soil provide many resources, including food, fuel, and building materials, that humans use. Student Objective: Given a dry lima bean seed, students will struggle to open it because of the hard seed coat, but will be able discover that seeds need water in order to soften the coat & sprout. Given a lima bean seed soaked in water overnight, students will be able to open it and identify the parts of the seed (seed coat, root & leaf (embryo)). Through the 4 experiments, students will be able to conclude (by the end of this unit) that plants need water, air, warmth, and sunlight to in order to grow. Anticipatory Set: Are you ready to become plant detectives today?

6 Purpose: The question we left off with yesterday was, Where do plants come from? right? Well, today we are going to explore that question. Input: Ask the students, Where do plants come from? Read p in Bits That Grow Big. Stop at the question, What s inside a seed? Explain to the students that they will be opening up a lima bean seed to see what is inside. Modeling: Let s review that section we just read from Bits That Grow Big. Who can tell me on thing that plants are used for? Allow every child to answer. We are going to do an activity today where you will be looking at this week s lunch menu and you ll be tracing the source of ingredients to plants. Do Monday s menu together with the class. Now I want you to be Plant Detectives and link as many ingredients you to can to plants for Tuesday-Thursday s menu. You will do this in pairs. (Assign 1 day to each pair).

You can share your findings with me tomorrow as we explore the question, Where do plants come from?

16 Plant Unit Samples: Plant Parts Root What will happen to this plant if we cut the roots off? We did an experiment and cut off the roots of one plant. We left the roots on an identical plant, so that we could compare their growth. Here is a picture of what happened to the plant with NO ROOTS. The plant died because it had no way to soak up water. Each time we watered it, the water drained out the bottom of the pot. We left the roots on this plant, so it was able to soak up the water that it needed to live. By doing this experiment, we learned that a plant needs ROOTS to suck up the water. Leaf The leaves are a very important part of the plant. The leaves make food for the plant. The leaves use carbon dioxide from the air and sunlight to produce the food for the plant. This process is called photosynthesis. Stem We did an experiment to see what the function of the stem is. We took a piece of celery and put it in a cup of water We then put red food coloring in the water and left the celery in the water overnight. When we came to school the next day, the leaves had turned red. From this

17 experiment, we learned that the stem carries the water to other parts of the plant, like the leaves. This is why the leaves turned red. Flower The flower allows a plant to reproduce. Reproduce means to create a new flower. The flower produces new seeds to be carried by the wind, bees, or animals' fur. The seeds are carried to new places to grow new plants. Fruit
