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 A 6 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=3 p. D 68 ux. RLk. M&inde x=75&list=PL 1 x 86 IFIADTh. NSaww. Eju 8 dn. QBwaz. NEn 6 P

Photosynthesis- The process plants use to make food. A plant needs light energy from the sun plus carbon dioxide(CO 2), 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=h 6 ev. Xswa. Qs&list=PL 1 x 86 IFIADTh. NSaww. Eju 8 dn. QBwaz. NEn 6 P&index=75 https: //www. youtube. com/watch? v=BLTc. VNy. Oh. Uc

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 Plants Animals • React to light, water, weather • 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 Venus Flytrap https: //www. youtube. com/watch? v=i 1 Hkzfn. PPo. U 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=Vwrs. L-l. CZYo https: //www. youtube. com/watch? v=Jnzwbip. Ju. AA &t=44 s

With a partner, read A 32 to A 36. 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. https: //www. youtube. com/watch? v=0 gii. DDBJVQ U

HOW YOU RATE Activity Page A 39 PULSE Beats in 15 sec BREATHING Beats in 1 min Breaths in 15 Breaths in 1 sec min At rest After exercise Read A 40 -A 41 in text with a partner. Compare and contrast how fish and humans breathe. ______________________________________

EXCRETION=CREATES WASTE ANIMALS • CREATE SOLID WASTE • CARBON DIOXIDE CREATED THROUGH BREATHING PLANTS • CREATE OXYGEN THROUGH PHOTOSYNTHESIS

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 A 18 -21 Complete questions: 1, 3, 4, 5 on page A 23 with a prtner
