Lesson 4 Living Things LIVING THINGS HAVE NEEDS Teacher Notes Science Inquiry Focus: What do plants need? Skills Development/Working Scientifically: • Questioning • Investigating and experimenting • Analysing (sorting and classifying) • Recording and communicating Science Learning Outcome: • Pupils learn how to take care of plants and provide for their needs by growing a radish from a seed. Technology/Engineering/Mathematics Links: • Using the ShowMe app to explain how they provided for the needs of their radish plant. • Explaining why particular needs have been grouped together to identify which living thing the needs are for. Background Information • Plants include trees, flowers, herbs, bushes, grasses, fruit-bearing plants, vines and ferns. • All plants have five basic needs that differ slightly from animals. Plants need air, sunlight, water, soil and space to grow and reproduce. • How plants meet their needs: Air—Plants absorb carbon dioxide from the air through their leaves. Sunlight—Plants absorb sunlight through their leaves. Water—Plants absorb water through their roots. Soil—Plants anchor themselves to the ground and absorb nutrients from the soil using their roots. Space—Plants have various seed dispersal methods for finding a place of their own. Plants with limited space will compete for nutrients and the weaker plant will not survive. • Unlike animals, plants create their own food through photosynthesis. Plants take carbon dioxide from the air, the sunlight and the water and convert these nutrients into glucose, which the plant uses to grow and produce oxygen, which it emits back into the environment. Assessment Focus: • Use the ShowMe app presentation to assess the pupil’s understanding of the needs of plants. • Use observational notes to monitor the pupil’s ability to participate in guided investigations, including following instructions, using tools and materials safely and resourcefully, and engaging in discussions about the investigation. Resources • One copy of page 18 for display on the interactive whiteboard • Online song The Needs of a Plant at • One copy of page 19 for display on the interactive whiteboard • One large, plastic cup for each pupil or each group. These will need small drainage holes in the bottom. • Three-quarters of a cup of soil for each pupil or each group • Water spray bottles for the class to share • One sunny area to place the cups • Two radish seeds for each pupil or each group • One tablet computer for each pupil • Online video How a Seed Grows at Viewing sample 16 Science: A STEM APPROACH Infants 978-1-912760-14-5 Prim-Ed Publishing – www.prim-ed.com
Living Things LIVING THINGS HAVE NEEDS Lesson 4 Lesson Plan Introduction: 1. Display the T-chart on page 18. Pupils look at the needs in the 'Yes' column and compare them to the needs in the 'No' column, before deciding which living thing has the needs shown in the 'Yes' column. Pupils name the five needs of plants, including water, soil, light, space and air. 2. As a class, listen to the song The Needs of a Plant at to reinforce the five basic needs of plants. Development: 3. Individually or in small groups, pupils conduct an experiment to grow radishes. Follow the simple step-by-step instructions on page 19 to conduct the experiment. Questions have been provided on page 19 to guide the investigation. Note: Remind pupils to write their name on their plastic cup so they can remember which plant is theirs. Pupils will also need to provide ongoing care to their radish every day to ensure its needs are met. This should be conducted with little guidance so that pupils have to think of the plant's needs. 4. After the radish seeds have been planted and placed in a sunny position, pupils use the ShowMe app on a tablet computer to create a video. Pupils take a photograph of their planted radish seeds using the app and draw the five needs of a plant around the outside of the photograph. Pupils can then create a voice-over to describe how they provided for their plant’s needs. Note: If resources are limited, pupils can draw a picture of their planted radish seeds and write a sentence about the needs of a plant. Differentiation • Less able pupils may create a short video using the camera on the tablet computer if they are unfamiliar with the ShowMe app. Pupils may also be given prompts to encourage them to think of the plant's needs; for example, ‘We breathe this into our lungs’ or 'Seeds are buried in this’. • More able pupils should be encouraged to label each need as well as drawing the images. Pupils may also be encouraged to find out what a radish is. Reflection: 5. Using a think-pair-share, pupils discuss the questions How do you think your seed will grow? and What will happen first, second, third …? 6. Watch the online video How a Seed Grows at .
