The Common Core and NGSS standards, while different, share similar goals. They should be thought of as working side by side with each other as teachers help students build skills like using evidence to back up claims in their writing. In science class students should always be given the opportunity to show their learning through their reading, writing, speaking, and listening skills.

As I have mentioned in other parts of my site, students have new expectations when it comes to what they are learning in science. These two sets of standards help students move towards a deeper understanding of content. Click on the link to see a full list of the new NGSS standards.
