Exceptional website with multiple resources for teaching various lessons on evolution...30+ links to individual pages with everything from PPT presentations, handouts, assessment tools, photos, and lab projects. May be the most complete place for a teacher to go to get everything he/she needs when putting together a lesson.

A free animated video presentation to show students how dinosaur bones become fossils. I liked this video because it really enhances the teaching of how bones eventually become fossils and will help students gain a better understanding of the long process and natural forces at work. It would be a great resource to use in conjunction with teaching students biological evolution (3-LS4).

This is a free 5-minute animated video that explains how animals adapt to changes in their environment for survival.The video also touches on the topic of natural selection by explaining that the traits suited for survival are then passed on from one generation to the next. I like this video because it's fun and would appeal to third graders but it's still teaching them the concepts that are introduced when teaching about biological evolution (3-LS4). I would show the video before delving into the variation among species and survival of the fittest topics where introduced. I think it's helpful when teaching concepts to make them relevant to the students, and this video shows how animals that the students are familiar with, such as tigers, obtained and use their camouflage.

A free application to see if dinosaur fossils have been found near your home. I selected this app because I thought it would be a fun way to bring studying dinosaur fossils a little closer to home. I would use it in the classroom in conjunction with studying evolution and diversity (3-LS4).

Free streaming video that shows the actual fossils from an ancient sea in the middle of Indiana. Put the mouse on highlighted sections of the rocks and a depiction of the fossil comes to life along with a brief summarization of what kind of fossil it is and how it lived. I really liked this program because it shows how different our world was millions of years ago, and the fact that the program animates whichever fossil you choose, brings the past to life. It would be a great resource to use when teaching biological evolution (3-LS4).

Free downloadable program in which students can build a dam in a virtual ecosystem and see how the animals and plants living there adapt. It shows students what happens to plants and animals when a change is introduced to their environment, some adapt and live while some die. I liked this program because students can place the dam in different places thus having different effects. I would use this program while studying biological evolution to visually demonstrate how a single change in the environment can have a drastic effect on the surrounding plant and animal life (3-LS4).

St. Louis Science Center's reconstruction of a dig site in the Badlands, of Montana. The fossils at the "dig site" are casts made from the real fossils that can be seen on display in the Prep lab. The Prep Lab features interactive tables where real dinosaur fossils are displayed. Students are also encouraged to ask the workers and volunteers questions. There are also many other interactive exhibits at the St. Louis Science Center that deal with fossils and how they are made, and beginning March 7, there will be a special traveling dinosaur exhibit to visit. I can't think of a better place to take a field trip when teaching about biological evolution (3-LS4) than the Science Center. A large majority of their interactive displays fit right in with what the students are learning, and having the hands-on experience will only enhance the students learning and make it more meaningful. I would take the field trip somewhere in the middle of teaching the material, that way I could reference what the students have already learned in class when we're on the field trip but they would find that there is still more to learn.

Free Whiteboard ready game in which students put the various parts of a dinosaur together to create a dinosaur that really existed or students can create their own. I really liked this game because it's fun while learning for the whole class. It not only teaches students about the variety of dinosaurs but also shows the similarities and differences in their structures. This would be a useful game to play when teaching about biological evolution (3-LS4), I would introduce it after the students had learned about the wide variety of dinosaurs that roamed the earth.
