Honey Bee Language Arts And Literature
Students see how nature and honey bees are presented in literature. They find and read poetry that include references to bees. Have them write their own poetry or Haiku.
Curated OER
Birth, Growth and... Reproduction!
Students research the Arctic Hare and chart relevant information under month headings. They compare the information about the Arctic hare to other Arctic mammals.

Teaching About the Properties of Water
Students use video, Internet research, graphs and tables, worksheets and hands-on experiments to investigate the properties of water in a lake environment. They work under direction or through an inquiry process.
Curated OER
Survey This!
Students examine biological information about George Washington focusing on his love of surveying. They explore cartography and field of surveying. They write a letter and make a map of Virginia.
Curated OER
Don't Stress Out
Ninth graders research stress and better ways to cope with it. They create a PowerPoint presentation showing coping strategies for stress with pictures and illustrations.
