Seventh Grade Biotechnology Science Projects (3 results)

Yogurt, biofuel, biodegradable plastics, and antibiotics are all examples of products based on biotechnology research and manufacturing techniques. What else will we be able to create as we use biotechnology in new ways? You can explore some of these techniques for yourself with projects from our biotechnology techniques science and engineering project list.

Science Fair Project Idea
Do you know why enzymes are oftentimes called the workhorses of biochemistry? It's because they can speed up a wide variety of chemical reactions, and chemists and biologists use enzymes to do all kinds of jobs. In this project, pectinase, an enzyme frequently used in the food industry, will be used to extract juice from apples. Read more

Safety Use care when using sharp knife to chop apples. Do not drink the juice produced in this experiment.
Science Fair Project Idea
In this project, you'll learn how to isolate DNA from onion cells, separating it from other cellular components in a manner that still preserves its structure and sequence. In the end, you'll have enough DNA to see with the unaided eye, and you'll be able to spool it to demonstrate its strand-like structure. Read more

Safety Use caution when handling ethanol because it is very flammable. Adult supervision is recommended for using the stove and a food processor or blender.
Science Fair Project Idea
Enzymes speed up chemical reactions by factors of at least a million. Now that's acceleration! This project investigates how temperature affects how fast these enzymatic reactions occur. Read more
