2 Directions: Match the words with the big ideas by writing the letter beside the idea. Use the same words in the short article below. Use key words and phrases from the article below to help. you. A B A C conifer fern ecosystem The green substance in plants A small furry, green plant The process of making oxygen D E F G H I J flowering plant habitat photosynthesis respiration chlorophyll moss biome A community of animals and plants A tree that produces cones A place where a plant or animal lives Made up of similar ecosystems A plant with feathery leaves and no flowers A process in which plants make energy A plant that has flowers There are four different types of plants. The first is the. These plants have flowers. The second is the _. This plant has cones. The next is the. These plants have no flowers, but has long roots and stems. The last type is. This type of plant has no flowers, stem leaves or roots. Leaves contain a chemical called _ which through a process called make energy. Oxygen is then created through _. All the plants around the world live in their own _. When you have similar habitats in one location we call this an _. When you have similar ecosystems together they are called biomes.. 68

3 Boys and girls, Did you know not all plants are the same? Plants can be many different shapes and sizes. Let s look at how we can tell the difference between the four different types of plants. Does the plant have flowers? Yes No It s a flowering plant. Does the plant have cones? Yes No It s a conifer. Does the plant have long roots, big leaves, long stem, but no flowers? It s a fern. Yes No It s a moss. 69

4 Read the description of each type of plant and glue it and the correct picture under the correct name. 1. Flowering plant 2. Conifer 3. Fern 4. Moss 70

5 Finish the table below with an O if the type of plant has that part or an X if it doesn t. Flowering plants Conifers Ferns Moss Leaves Stem Roots Flowers Cones Fruit Seeds 71

7 Boys and girls, Have you ever had a close look at a leaf? If you did and you compared it to a leaf from another plant you would see that there are many differences between them. Let s look at how we can classify leaves. Leaves are the plants food factory. A leaf is a flat, thin plant organ that uses the sun to make its own food. In general leaves are green and use the chemical called chlorophyll to catch energy from the sun. This process is known as photosynthesis. The energy is used to mix water from the soil and carbon dioxide gas from the air to make sugar. Oxygen is released in a process called respiration. The leaf acts almost like a solar panel for attracting energy from the sun. We eat many kinds of leaf vegetables everyday such as lettuce. Leaf parts: 73

8 As you can see there are many different shapes of leaves. However, there are other ways to classify leaves Classifying leaves 1. Type of leaf 2. Leaf arrangement 74

9 3. Leaf shape 75

10 4. Leaf edge 76

11 5. Leaf veins 6. Leaf base 77

12 Use a magnifying glass and color pencils to investigate and classify leaves Step 1. Look at each leaf carefully with the magnifying glass. Step 2. Use your booklet to complete the information about its characteristics. 3. Step 3. Draw a color picture of your leaf in the box Leaf 1 Length: Width: Type of leaf: Arrangement: Shape: Edge: Veins: Leaf 2 Length: Width: Type of leaf: Arrangement: Shape: Edge: Veins: 78

14 Boys and girls, Did you know that a piece of celery is also a stem and that the big tree in the playground also has a stem which we call a trunk?. Plant stems: Label the tree stem 80

15 Use a magnifying glass and color pencils to draw the cross-section of four different stems Step 1. Look at the crosssection of the stem with Step 2. Draw what you see into each box. the magnifying glass

16 Use straws and cups to see how much energy is required for a stem to transport water from the roots to other parts of the plant. (straw races) Step. 1. Each student choose a straw. Step 2. Each student put 50 ml of water into their cup Step. 3 Race the other students to drink the Step. 4. Record your results. water in the cup.. Which straw was the fastest? What does this mean for a stem? 82

17 Boys and girls, Did you know that there are only 2 types of roots? They are usually found under the soil, but sometimes, the roots of big trees will grow out of the ground. Plant roots: Types of roots: 83

18 Use a carrot to see how a taproot grows Step 1. Fill a glass half full with water. Step 2. Cut the end off of a vegetable Step 3. Put the carrot in the plate of water. Step 4. Put the glass near a window that lets in sunshine Step 5. Watch the carrot for a few days. Step 6. Draw a picture of your experiment. Draw a picture of what happened to the carrot. 84

19 Across 1. Carrots are this type of root 3. a root that looks like many pieces of cotton 4. A plant that has flowers 6. A plant with long roots and stems, big leaves and no flowers. 8. A plant with cones. 9. Chemical in leaves Down 2. Process to catch energy from the sun 5. When oxygen is released from the leaves 7. Has no stem, leaves, flower or roots 85

20 Boys and girls, Did you know an ecosystem as a tiny world within our world. Here, living things, like plants and animals, interact with non-living elements, including water, rocks, soil and temperature. Every part of the ecosystem influences everything else. An ecosystem exists within a larger area called a biome. Here s an example of an Ecosystem: Within the ecosystem there are a number of habitats. Some of these habitats are made up of streams and creeks. Here, fish, birds, turtles and snakes live. In another part of the ecosystem there are trees and plants. This is another habitat in which different animals and plants live. There can be any number of habitats within an ecosystem. When you have similar ecosystems together they are called biomes. There are 7 main biomes that make up our world: 1. Rain forest 5. Grassland 2. Savannah 6. Tundra 3. Desert 7. Taiga forest 4. Temperate forest 86

21 Color in the different biomes on your map. Rainforest Grassland Savannah Tundra Desert Taiga forest Temperate forest Read your biome activity cards. Look at the pictures of the type of plants found in that biome. Create a poster that shows the characteristics of the biome and the type of plants that live there Step 1. Read your biome activity card. Step 2. Plan your poster on the next page. Step 3. Complete your poster on cardboard, neatly and in color. 87

22 Plan your poster. 88
