Plant Growth Experiment Analysis

Julie from NGSS Nerd introduces a performance expectation, 5 LS 1-1, focusing on how plants get materials for growth mainly from air and water. She sets up an experiment with five plants, each missing one resource, to demonstrate this concept. The video details the materials needed, plant preparation, and experiment setup. Students observe plant growth over weeks, noting which plants survive. The video concludes with a summary of findings and additional resources for teachers.

What is the main focus of the performance expectation 5 LS 1-1?

• Plants grow better in sunlight.

• Plants get materials from soil.

• Plants get materials from air and water.

• Plants need fertilizers for growth.

In the experiment setup, how many plants are used?

• Four

• Three

• Five

• Six

Which material is NOT needed for the experiment?

• Fertilizer

• Shoebox

• Mason jars

• Post-it notes

What is used to remove carbon dioxide from a plant?

• A grow light

• A shoebox

• A sealed container

• A plastic bag

How is the plant without soil supported in the experiment?

• Using a plastic bag

• Using a shoebox

• Using a smaller container inside a larger one

• Using a grow light

What should be done to the plant that receives no sunlight?

• Put it in a shoebox

• Leave it outside

• Place it in a sealed container

• Cover it with a plastic bag

During the experiment, which plant should be watered regularly?

• Plant with no water

• Plant with no carbon dioxide

• Plant with all resources

• Plant with no soil

What is a likely observation for the plant with no water after a week?

• It will shrivel and become shorter.

• It will remain the same.

• It will grow taller.

• It will turn green.

What is the expected outcome for the plant with no soil?

• It will die immediately.

• It will not need water.

• It will grow as well as the plant with all resources.

• It will survive but not grow as well.

What conclusion can be drawn about the necessity of soil for plant survival?

• Soil is essential for plant survival.

• Plants can survive without soil if they have water and sunlight.

• Soil is the only source of nutrients for plants.

• Plants need soil more than water.
