Exploring Inheritance and Traits in Grade 3

In this lesson, third-grade students explore how the environment can affect inherited traits through a celery investigation. The video guides students to set up the experiment, observe changes, and analyze results to understand the role of environmental factors. Students are encouraged to record their observations and share findings, fostering critical thinking and scientific inquiry.

What is the main focus of lesson 3.4?

• The impact of pollution on wildlife

• Genetic inheritance patterns in plants

• Methods of conservation in wildlife biology

• The role of the environment in trait development

What materials are suggested for note-taking during the lesson?

• Laptop or tablet

• Smartphone app

• Investigation notebook or any paper

• Audio recording device

What was the main question investigated with the salary experiment?

• What are the genetic markers of salary?

• Can the environment influence inherited traits?

• How do different soils affect plant health?

• How does light affect plant growth?

What color was used to test the environmental effect on salary?

• Blue

• Green

• Yellow

• Red

What should students do if they observe no color change in the salary?

• Discard the results

• Ignore the observation

• Ask for adult help to cut the salary

• Change the food dye

What is the purpose of recording observations in a notebook?

• To analyze the results of the investigation

• To submit as a formal report

• To share with peers for feedback

• To prepare for the final exam

What were the colors of the food dye used in the investigation?

• Green and yellow

• Blue and green

• Red and blue

• Blue and yellow

According to the results, how did the salary get the trait of being blue-green?

• Through genetic modification

• By absorbing blue food dye

• Through soil nutrients

• Due to exposure to sunlight

How should students use the results of their observations?

• To compare with classmates' results

• To disprove the initial question

• To create a new experiment

• To support their hypotheses

What should students do after recording their observations and conclusions?

• Email them to the teacher

• Save them for the end of the semester

• Discuss them with someone at home

• Post them on a class blog
