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

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?

MOVEMENT – Release Energy
Plants release energy
through their life
processes like growth
and photosynthesis.
Animals release energy by
movement.

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.
