Genetic and Environmental Factors in Growth
Written by Adi Ackerman, Head Teacher
"Genetic and Environmental Factors in Growth" is written for 7th Grade (Ages 12-13), and it covers NGSS MS-LS1-5. A 6th grader who is already steady on living things can use it too, and an older student can use it as a short review.

7th grade science worksheet: graph how genes and the environment shape traits, from blue hydrangeas to the Himalayan rabbit. Answer key included. Part of our reproduction and plant growth living things collection. Aligned to NGSS standards.
How do I use this worksheet?
Use the strategies sheet to open a unit on reproduction. Use the growth sheet for genes and environment, and the modes sheet for review.
What students will practice
- Students will explain how genes set a range for a trait and the environment moves it within that range.
- Students will draw a bar graph from a table of heights.
- Students will name the factor, such as light, water or temperature, behind each difference in a set of examples.

FAQ
How do I use this reproduction and plant growth worksheet?
⌄
Use the strategies sheet to open a unit on reproduction. Use the growth sheet for genes and environment, and the modes sheet for review.
What does this worksheet teach?
⌄
Graph how genes and the environment shape traits, from blue hydrangeas to the Himalayan rabbit. The directions on the page read: Read the text. Draw each table height as a bar above L, M or H on the grid. An answer key is included.
Can I use this reproduction and plant growth worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 7th grade living things, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.
Why do some animals have many offspring and others few?
⌄
An organism has only so much energy and time. A cod releases millions of eggs and leaves, while a penguin or elephant cares for few young.
What is the difference between one parent and two parent reproduction?
⌄
With one parent offspring usually have the same DNA. With two parents DNA is mixed, so offspring vary.
Can the environment change a trait?
⌄
Yes. Genes set a range, and light, water, food and temperature can move an organism up or down within it.
