Question

Hypothesis: If an impatiens flower experiences drought, then its leaves curl up and wilt as a response to water loss and as a means to reduce evaporation (water loss from the leaves).

What is the materials you need for this experiment ?

Independent Variable ?

Dependent Variable ?

Controlled Variable ?

Answer 1

For this experiment, you will need impatiens flowers, soil, containers, and a way to measure water. The independent variable is drought, and the dependent variable is the curling up and wilting of the leaves. Controlled variables include water amount, temperature, sunlight, and container type.

Step-by-step explanation:

The materials needed for this experiment include impatiens flowers, containers for planting the flowers, soil, a watering can or dropper, and a way to measure the amount of water given to each plant.

The independent variable in this experiment is the presence or absence of drought. The dependent variable is the curling up and wilting of the impatiens leaves. The controlled variables include the amount of water given to each plant, the temperature, the amount of sunlight, and the type and size of the containers.
