This site shows different activities and "labs" to show or work through to demonstrate the first law of physics. I feel like depending on what activities you choose to do this could easily stretch across multiple grades levels.

This is site talks about the ways to defy the laws of physics through space travel.

This is super interesting. It has many visuals and simple notes to explain the movement of objects.This could easily be a replacement for a power point for the day. There are also quizzes and games students can play or work through after the lesson to help assess their learning.

Learn about Newton's three laws that describe the properties of motion with this Science Channel interactive. Students must make sure to go through all laws, the bio section and glossary in order to do well on the quiz portion. This could easily turn into a lesson when each student is given a section to learn and present to the rest of the class before all taking the quiz. This would show comprehension on a personal level from self teaching as well as listening from peers.

This is a great source for showing students chain reactions and to as how the environment is affect by our decisions. I feel like this could be used with younger students but also with a bit older students as a reminder for earth day.

This is super cool! It is an interactive encyclopedia. Students can choose different categories in science as well as different sub categories. Once in a subcategory students will find: vocabulary words, a slide show, related topics and a test.This again is beneficial as a study tool as well as a research resource.

Journey North classrooms track bald eagle migration each season. This goes into details on things such as their territories, nest building, courtship, and babies! I love this site its so interesting going into more depth in a specific animals life. There are other animals on the site as well.

An interactive woodland and pond scene where children aged 8-9 can spot plants and animals, and then place them into food chains. This also gives little factoids about each living thing in the picture and students are forced to identify living creatures in their environment as well.

The science movies teach kids educational topics like animals, habitats, plants, land, matter, forces, space, energy, and weather. I really enjoy the animals section since it talked about different types of animals and their habits such as hibernation, camouflage, migration and food chains. Throughout the early years i feel like this would benefit students since they are given videos, and text. This site is reliable and gears towards many learning styles.
