Science: Plants

Adventure starts NOW!

Hi guys! Look at this plant? Don't you wonder how plants grow? Lets take a look in the backyard garden!

Look at this sapling. It has just been planted. It needs water and sunlight to survive and grow into a adult plant!

The sapling will grow into a big adult flower! But it needs to go through stages. First lets talk about what nutrients plants need!

Multiple Choice

What do you think plants need to survive?

• Water

• Soil

• Sunlight

• Water and Sunlight

Surprisingly plants DONT need soil! Soil just gives them extra helping nutrients. People can actually grow plants fully in water! They mostly need WATER and SUNLIGHT.

Multiple Choice

What does the leaf do?

• It is where the plant makes its food

• It captures sunlight energy

• It absorbs rain water

• It provides protection for the plant

Multiple Choice

What is the main function of the stem

• A plant structure that provides support and connects the leaves with the roots

• To transport nutrients to the rest of the plants

• To keep the plant upright and stop blowing in the wind

• Where the plant makes its food

Multiple Choice

What is the main function of the roots

• To store water and food

• To provide support and keep it stable

• To absorb water and minerals in the soil

• To stop soil erosion

This is a stage the seed has to go through. It is called GERMINATION! Germination refers to the process by which an organism grows from a seed or a spore. The most common forms of germination include a seed sprouting to form a seedling and the formation of a sporeling from a spore. 

Multiple Choice

What will happen if a plant does not get water?

• it grows slower

• it will dry up and die

• it grows faster

This seedling also has to go through photosynthesis. Photosynthesis is the process that enables plants to get energy from the sun. Light energy from the sun is converted into chemical energy by chlorophyll. 

Multiple Choice

What is one way to  know if a plant is an adult?

• it has a flower
• it’s green
• it’s big
• it has a deep voice

Multiple Select

What does photosynthesis do?

• Helps plant get sunlight.

• Helps plant get better nutrients.

• Helps plant get to the adult stage.

Yay! This plant has grown! This adult plant now has to release its seed. Then it can regrow from all other kinds of places. Seeds usually get carried by birds. But first lets talk about POLLINATION!

Multiple Choice

A student places three identical plants in the same type of containers, uses the same type of soil and the same amount of water for each plant. This student places the three plants in three different locations. Plant A is placed in a sunny area, Plant B is placed in a shaded location, and Plant C is placed in the dark room. Each day this student records the growth of each plant. What is the different variable in this investigation?

• the soil

• the amount of water

• the amount of light

• the growth of each plant

Multiple Choice

Seeds can move from one place to another by

• wind

• water

• animals

• wind, water, and animals

Bees mostly use pollination for the use of HONEY. Hint to the next science lesson! Lets go onto how the seed is spread!

This seed is being carried by a bird! The bird will fly away somewhere and drop the seed. Then the seed will grow and the process will happen again!

Multiple Choice

When the process of photosynthesis is complete, the plant releases...

• ...sunlight.

• ...oxygen.

• ...water.

• ...soil.

Multiple Choice

True or False:

Plants are non-living things.

• TRUE

• FALSE

Multiple Choice

True or False:

Plants produce their own food.

• TRUE

• FALSE

Multiple Choice

Plants have ways of getting their seeds to travel away from them because ______.

• they want to help animals.
• seeds that travel away from the parent are more likely to get light.
• seeds need water to grow.

What have we learned?

• Plants have 2 major steps, Germination, Photosynthesis

• What plants need to grow

• How it affects other animals

• Pollination

• How to grow our own plants with success!
