As the novelty of PowerPoint presentations in the K-12 classroom fades, the dim lights and streams of text could inspire sleep instead of excitement in science. There are ways that science can be made interesting through PowerPoints. Interactions, great pictures and graphics can really help make a point and share a story.

Fortunately many teachers and people who support education are willing to share their efforts. Here are several powerful sites for science PowerPoint presentations. Of course, with any collections of resources, not all are great so you must browse through and pick and modify. I think combinations of interactive and exciting elements from diverse PowerPoints can make you have a presentation with many strong elements but that is tailored for your students and curriculum. 

Impressive Large Collections

Assigning Activity Objects and PPTs with Adaptive Curriculum

Adaptive Curriculum. With student subscriptions teachers not only assign great interactive science Activity Objects but they can also assign or provide any online resources. So students can easily access great PowerPoint presentations without remembering complicated addresses. For instance in the picture to the right a lesson plan is being created with the Activity Object “Color Mixing: Paints and Lights” and is combined with two PowerPoint presentations.
