Understanding the Seven Life Processes in Science
Explore the fascinating world of life processes through topics such as characteristics of life, movement, photosynthesis, reproduction, and sensitivity. Delve into the functions that define living organisms and learn how plants and animals sustain life through energy release, growth, and reproduction. Discover the interconnectedness of various biological processes that keep organisms alive and thriving.

Life Processes Science Unit 1
Characteristics of life https://www.youtube.com/watch?v=Gy60Bq CnTG4 https://www.youtube.com/watch?v=juxLuo- sH6M&list=PL1x86IFIADThNSawwEju8dnQBwa zNEn6P&index=125&t=0s 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=h6- evXswaQs&list=PL1x86IFIADThNSawwEju8dnQBwazNEn6P&index=75 https://www.youtube.com/watch?v=BLTcVNyOhUc
1. Stimulus- Anything that causes a living thing to react 2. External Stimulus- Anything in an organism s environment that causes it to react. Example: ________________ 3. Internal Stimulus- Anything within an organism that causes it to react. Example: Hunger React to light, water, weather Plants Use their 5 senses to react Animals
How do living things detect stimuli? A cold wind blows on you A plant needs water A moth detects a bat s sound waves Venus Flytrap https://www.youtube.com/watch?v=i1HkzfnPPoU A dog sees a can of food opening
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. https://www.youtube.com/watch?v=VwrsL-lCZYo https://www.youtube.com/watch?v=JnzwbipJuAA &t=44s
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 3 Detail 2 Detail 1 Answer these questions: What category of food do you eat most of? Least of? What can you do to make your diet better?
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. https://www.youtube.com/watch?v=0giiDDBJVQ U
HOW YOU RATE Activity Page A 39 PULSE BREATHING Beats in 15 sec Beats in 1 min Breaths in 15 sec Breaths in 1 min At rest After exercise Read A 40-A41 in text with a partner. Compare and contrast how fish and humans breathe. __________________________________________________________________________ __________________________________________________________________________
EXCRETION=CREATES WASTE ANIMALS PLANTS Image result for image elephant CREATE OXYGEN THROUGH PHOTOSYNTHESIS CREATE SOLID WASTE CARBON DIOXIDE CREATED THROUGH BREATHING
GROWTH- The development of a living thing often by growing in size and maturity. Animals need to grow to reproduce , care for selves and be productive. Question: How is your growth similar to a seed growing? Read text A18-21 Complete questions: 1,3, 4, 5 on page A23 with a prtner
