Plant Growth Experiment Concepts

The video introduces the basic needs of plants: water, soil, and sunlight. It sets up an experiment to test plant growth under different conditions by varying these needs. The video lists materials required and provides step-by-step instructions for conducting the experiment. It concludes with a call for viewer engagement and thanks to Google Making Science.

What are the three main things that plants need to grow?

• Soil, water, and air

• Sunlight, air, and nutrients

• Air, water, and food

• Water, soil, and sunlight

Why do plants need sunlight?

• To make their own food

• To attract insects

• To keep warm

• To grow taller

What is the process called where plants make their own food using sunlight?

• Respiration

• Transpiration

• Photosynthesis

In the experiment, what will happen to the plant that receives no water?

• It will grow normally

• It will grow slowly

• It will dry up and not grow

• It will grow faster

What is the purpose of using a plant journal in the experiment?

• To record the weather

• To track plant growth and changes

• To write down plant names

• To draw pictures of the plants

What should you do if the soil or sand feels dry during the experiment?

• Add more soil

• Move the plants to a different location

• Add more sand

• Water the plants

Why is it important to use the same kind of seeds for all containers in the experiment?

• To make it easier to plant

• To ensure consistent results

• To save money

• To use up old seeds

What should you do if you don't have a camera to document the plant growth?

• Write a description

• Draw what you see

• Skip documenting

• Use a video camera

What is the role of the cardboard square in the experiment?

• To block sunlight from one plant

• To cover the soil

• To label the plants

• To hold the plants upright

How long might it take for the plants to grow in the experiment?

• A few years

• A few hours

• A few weeks to a month

• A few days
