Science Investigation

We are learning what plants need to survive

We are learning how plants respond to environmental changes.

What do plants need to survive?

Water

Sun

Soil/ fertilizer/ dirt

Oxygen

Carbon dioxide

We are going to conduct a science investigation to determine what will happen to plants when their environment changes. In this assignment we will be changing the environment of each of the mint plants and the potatoes.

What will we need to make this a fair investigation?

• Lots of plants in case one fails
• Make sure they all get the same amount of sun
• Make sure they still have the other things they need to survive
• Monitor progress every few days - with pictures
• Have a “control” plant, that we do all the right things to.

Method:

• Suffocate a plant - by putting it in a container
• Stop watering a plant
• Take out the soil
• Put in the dark
• Normal plant - the control

Hypothesis:

My hypothesis is that the plant would slowly rot and without the resources needed for it to survive.

The plant I will be observing is: Mint plant.

The looked over plant

Observation day 1:It still look fresh.

Observation day 3:Starting to die.

Observation day 7:No leave is fresh it is dead.

Explanation: Why did this happen to my plant?

Because their was no soil on it and we never feed it with water.
