What are living things?
• Organisms
• All living things
Living Things Grow
• What happens when you plant a
seed?
• What happens to a baby kitten?
All living things grow
• Over time all living things change

things?
Answer

to their surroundings, and
reproduce.

tell?

respond to its surroundings.
What do living things Need?

that surround an organism
Food
• Energy
• How to plants get their food?

need to stay healthy?
Answer
• Food
• Water
• Gases
• Space
Question????

Question????
• Why do organisms need water?
Answer
• To break down food and get rid of
waste
Gases
• Animals need oxygen to survive
• Where do you find oxygen?
Answer
• Air and water
Question
• Who uses oxygen in the water?
Answer
• Clams, fish, and most sea animals
Plants
• What do plants need?
Answer
• Need oxygen and a gas called

change carbon dioxide and water
into food
Space
• Organisms need space
• What is an organism?
Answer?
• All living things
space
• Plants need space to grow and to
get water and sunlight
• Animals need space to move and
find food
Questions
• Does a whale and goldfish need the
same amount of space?
Question
• How is a classroom an environment?
• What are some living things in nthe
classroom?
• What are some nonliving things in
the classroom?

crowded environment?
Plants and Their Parts
Lesson 2
What are plants?
• What are
characteristics of
plants?
• Make their own
food
• Plants do not eat
living things

Plants
• What are some common structures
found in most plants?
• Roots
• Stems
• leaves
Vocabulary
• Structures
• Parts of plants
• Help plants get what they need
What three structures do
plants have?
• Roots
• Stems
• leaves
Critical thinking
• Most plants do not have structures
for eating. What might be a reason
for this?
• Plants do not eat food. They make
their food from energy from the
Sun.
What is a root?
• Plants take in water through their
roots
• Roots also hold a structure in place
• Carrots and radishes have one thick
root called a taproot.
Roots
• Not all plants have one big root
(taproot) others have a web design
• Roots take in water, hold a root in
place
• What else do plants absorb through
their roots?
Roots
• Nutrients…..
• Substance that help living things
grow and stay healthy
• Nutrients are part of the soil
Roots
• Can you think of roots we can eat?
• Carrots
• Radishes
• Sweet potatoes
Review Quiz Time
• How do roots help a plant meet its
needs?
• What is a root?
• Name a root we can eat.
Question Review
• What is a nutrient?
• Where do we find nutrients?
Stems
• Stems are structures that hold up a
plant
• Stems hold up leaves so that they
get sunlight
• Stem carries water, nutrients and
food throughout the plant
Question time
• What are the three functions of a
stem?
• Name one root we can eat.
• What is the function of the root.
Stems
• Not all stems are the same
• Stems can be soft and green
• They can be hard and woody
Review
• How are plant roots different?
• How are roots alike?
• What is a stem?
Leaves
• Many shapes and sizes
• Leaf is where a plant makes its
food
• Photosynthesis is the process in
which plants make their own food
Photosynthesis
• Process in which plants make their
own food
• Use energy from the Sun
• Change carbon dioxide and water
into sugars
• Sugars are food for plants
Questions
• What job do leaves have?
• What is photosynthesis?
Answers
• Make food for the plant
• The process in which plants make
food using energy from the sun
Questions
• What are some different types of
leaves?
• What is the jobs of leaves?
• What enters through the tiny
openings in the leaf?
Answers
• Narrow and pointy like a fern
• Broad and flat like the maple
•
•
•
•
Shaped like a needle
Make carbon dioxide
Soak up the sunlight
Make food
Leaves
• Chlorophyll gives leaves their color
• Plants give off oxygen
• People and animals need oxygen to
live
Questions
• Where do plants get energy to
make food?
• What does a plant to make food?
• What do plants give off during
photosynthesis?
Animals
• Use senses to get information
• Wolf growls when sees , gears,
smells another wolf near its young.
• Snake may lie in the sun when it is
cold

hungry
• Bees sting when they fear danger
Senses

• Parts helps animals get what they
need
• Legs, fins, wings, tails
