A great resource for help with fifth-grade science is Kids.USA.gov/Science. Click on "Kids Grade K-5" for access to scientist and inventor biographies, as well as facts about well-known scientific discoveries, plant and animal life sciences, caring for the environment and exploring the universe.
Resource links provide help for guiding kids through the ins and outs of science-based career and job opportunities, such as archeology, space exploration, marine biology and wildlife protection. The site introduces fifth graders to experts in various fields from the National Park Service, the National Museum of Natural History, NASA and the National Institutes of Health. The site also suggests ideas for science projects and details each necessary step, from choosing a topic, to stating a hypothesis, to researching, report writing and constructing an exhibit. Help is available for assisting kids as they explore ideas best suited to their individual skill, creativity and interest levels.
Kids.gov offers age-appropriate science games that help kids learn about animal habitats, climate change, earthquakes and water cycles. Kids can take a virtual field trip to Jet Propulsion Laboratory, play laser tag in NASA's "Cosmic Corridor," and visit interactive sites that help them explore the wonders of comet travel through the solar system.
