Effect of Colored Light on Plant Growth

In this video, Justin explores whether the color of light affects plant growth. He observes that plants near a stained glass window grow more than those near a regular window, prompting an investigation using the scientific method. The experiment involves growing beans under red, green, and white light, with detailed instructions and materials provided. Students are encouraged to form hypotheses, collect data, and draw conclusions. The lesson concludes with a motivational message about curiosity and discovery.

What observation led Justin to question the effect of light color on plant growth?

• Plants in the dark grew more.

• Plants in front of a stained glass window grew more.

• All plants grew at the same rate.

• Plants in front of a normal window grew more.

What is the main purpose of this lesson?

• To explore the uses of stained glass.

• To understand the history of plant growth.

• To apply the scientific method to study light effects on plants.

• To learn about different types of plants.

What process do plants use light energy for?

• Fermentation

• Digestion

• Respiration

• Photosynthesis

Which colors of light are being tested in the experiment?

• Red and green

• Blue and yellow

• Black and white

• Purple and orange

What type of seeds are used in the experiment?

• Bean seeds

• Corn seeds

• Pea seeds

• Sunflower seeds

What is needed to germinate the beans?

• Water, paper towels, and a plastic bag

• Sand and gravel

• Fertilizer and pots

• Soil and sunlight

How is the color of light controlled for each plant?

• Using tinted windows

• Using different colored pots

• Using colored cellophane over boxes

• Using colored light bulbs

What should you do if your plants need more time to grow?

• Stop the experiment

• Continue the experiment and extend the data table

• Change the type of seeds

• Move the plants to a different location

What is the final message Justin leaves with the viewers?

• Light is not important for plants.

• Plants need water to grow.

• Always follow instructions.

• Curiosity is the architect of discovery.

What is the main goal of the experiment?

• To grow the tallest plant possible.

• To determine if colored light affects plant growth.

• To see which plant grows the fastest.

• To find the best soil for plants.
