STAAR BIOLOGY REVIEW VIDEOS

Help for you when you need it most

What's this for:

Let's say you're stuck and you don't remember how many chromosomes are in a human gamete or the function of the plasma membrane or how plants get their energy from the sun. Below are a series of review videos broken down into the five sections of the STAAR test. If you're in a bind and can't remember some info that you need, watch the video and put your mind to rest. Good luck and know that your biology teacher is behind you and believes in you.
If there is an area that you are struggling with you may consider using an app or online tool like Evernote to take notes on the videos. It's free and you can use it on a computer, a phone, or any type of tablet.
