I made these cheat sheets for my 7s to help them with our Meiosis and DNA unit. These are two of the most complex topics we cover in Life Science and it helps them synthesize all of the information into one page.
Download these free PDFs below:
DNA Cheat Sheet – 2017 – Google Docs – this covers the fundamentals of DNA at a 7th grade level
Meiosis Summary Cheat Sheet – 2017 – this covers the basics of Meiosis along with a comparison to Mitosis at each stage for a 7th grade level
It is that time of year again: time to ask everyone you know to save their plastic Easter eggs and that you will be more than happy to take them off their hands – once the kids have emptied out the goodies, of course!

- NOTE: the colors in this activity represent Incomplete Dominance and their outcomes
- Here is a nice review of the three different types of dominance from Khan Academy (video link)
- For Dominant and Recessive Traits only, this lesson would have to be modified and use 1 whole egg for each parent, and the answers would NOT be inside the eggs:
- Blue & Yellow only (BB, Bb = blue, bb = yellow)
- Blue egg – 2 blue pieces
- Blue egg – 1 blue piece, 1 yellow piece
- Yellow egg – 2 yellow pieces
- Open eggs for genotypes, then make punnett squares
- Purple & Pink only (PP, Pp = Purple, pp = pink)
