Biology Lab: Cell Structure and Function. This is a very extensive lab lesson plan on cell structure and function. This lab can be used with grades 6 through 12. It is great for younger students just learning about cells, and it can be a great review for older students. This lab would be a great activity to review the care and use of a microscope.
Biology Lab: Simple DNA (deoxyribonucleic acid) Extraction. This is one of my favorite labs/activities that I do with my Biology I students. It doesn't take long to do, it uses very simple, household materials, and it works every time! There is no number crunching or data analysis, but just a fun activity that your students will really enjoy.
