1. Life Processes
Science Unit 1

2. Characteristics of life
Write down what this video is about. What do you think we will be studying in science?

3. MRS NERG! 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!

4. 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

5. 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

6. PHOTOSYNTHESIS

7. 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.

8. REPRODUCTION- To make more
Living things must reproduce because they would otherwise go extinct.
baby
child
adult
adolescent

9. Reproduction in Animals
Creates more of the same species
Reproduction in plants
Pollination, seed dispersal, germination

10. SENSITIVITY- reacting to your surroundings
Stimulus and response

11. React to light, water, weather
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

12. 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
A dog sees a can of food opening

13. 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

14. Digestive System- Breaks down food and gives nutrients to the body and gives animals energy.

15. With a partner, read A32 to A36
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.

Answer these questions:
What category of food do you eat most of?
Least of?
What can you do to make your diet better?

16. 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.
