Lesson 5: Matter & Growth

Front

What is matter?

Back

Matter is anything that has mass and takes up space.

Front

True or false: Plants can increase in matter by taking in air, water, and light.

Back

True

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in an experiment, often affected by changes in the independent variable.

Front

In the inch plant experiment, how did we measure plant growth?

Back

We measured plant growth by observing the increase in the plant's weight.

Front

True or false: If a plant increases in weight, it also increases in matter.

Back

True

Front

What evidence shows that a factor is necessary for plant growth?

Back

If the factor is present and the plant grows, it indicates that the factor is necessary. If the factor is absent and the plant does not grow, it further supports this.

Front

What are the main factors necessary for plant growth?

Back

The main factors necessary for plant growth include light, air, water, and soil.

Front

What is the role of light in plant growth?

Back

Light is essential for photosynthesis, the process by which plants convert light energy into chemical energy.

Front

How does water contribute to plant growth?

Back

Water is crucial for transporting nutrients, maintaining cell structure, and facilitating photosynthesis.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to synthesize foods with the help of chlorophyll.
