Life Processes Science Unit 1 Characteristics of life Write down what this video is about. What do you think we will be studying in science? Watch the power point about the 7 life processes Life Processes.ppt Let’s review: The 7 processes that make something alive are: MRS NERG! Answer the question in your notebook: What does it mean to be alive? Life Process- A function that a living thing performs to stay alive and produce more of it’s own kind. Read page A6 in the text book Why does the yellow duck have more in common with the grass than the bronze duck? Meet MRS NERG http://www.oum.ox.ac.uk/thezone/animals/life/ MOVEMENT – Release Energy Plants release energy through their life processes like growth and photosynthesis. Animals release energy by movement. Photosynthesis Movement Reproduction Growth PLANTS ANIMALS PHOTOSYNTHESIS https://www.youtube.com/watch?v=3pD68uxRLkM&inde x=75&list=PL1x86IFIADThNSawwEju8dnQBwazNEn6P Photosynthesis- The process plants use to make food. A plant needs light energy from the sun plus carbon dioxide(CO2), plus water. The plant will make sugar and oxygen. REPRODUCTION- To make more Living things must reproduce because they would otherwise go extinct. baby child adult adolescent Reproduction in Animals • Creates more of the same species Reproduction in plants • Pollination, seed dispersal, germination SENSITIVITY- reacting to your surroundings Stimulus and response https://www.youtube.com/watch?v=h6evXswaQs&list=PL1x86IFIADThNSawwEju8dnQBwazNEn6P&index=75 1. Stimulus- Anything that causes a living thing to react 2. External Stimulus- Anything in an organism’s environment that causes it to react. 3. Internal Stimulus- Anything within an organism that causes it to react.2 Plants • React to light, water, weather Animals • Use their 5 senses to react How do living things detect stimuli? A cold wind blows on you A plant needs water A moth detects a bat’s sound waves A dog sees a can of food opening Venus Flytrap NUTRITION-Taking in nutrients Makes seeds Moves water from roots and leaves Makes food through Photosynthesis. It needs water + sun + carbon dioxide Suck up water and minerals Digestive System- Breaks down food and gives nutrients to the body and gives animals energy. With a partner, read A32 to A36. Copy and complete the chart below in your notebook. Hint: Use the chart on A 33 to help. Main Idea: The digestive system breaks down food and gives nutrients to the body which gives us energy. Detail 1 Detail 2 Answer these questions: • What category of food do you eat most of? • Least of? • What can you do to make your diet better? Detail 3 EXCRETION- Creates waste and RESPIRATION- breathing Respiratory System- A group of organs that work together to bring air in and push it back out of the body.
