What Teachers are Saying about Keystone Science Resources

I used this today to help my students see the importance of stoichiometry and they appreciated that I tried to give them relevant examples! These problems were on-point and exactly what I needed!

This was a great resource to use with Keystone Biology Prep once content was finished. Great work and highly recommend.

I love this resource. Having a word wall with the pictures has helped my students retain vocab. I am hoping this helps with the upcoming state test.

My first time having my honors students complete a debate. This pack is fantastic. Thank you so much for the step by step and guidelines. It not only helped them, but me too!

This was a wonderful presentation. I broke it down over the course of a couple of class periods in order to add some additional content that I needed to cover along with activities. It was great having the guided notes attached as well. My students commented that they wish more of our presentations had guided notes!

Probably the best resource I have purchased on TpT. It took so much work off my plate.
