REVIEW:
EdHead uses simple animations to help students understand science
concepts. Simple Machines helps students, grades two through six,
to learn about simple and compound machines. The five animated activities
in this module teach children about levers, wheels and axles, inclined
planes, gears, wedges, screws, and pulleys by interactively exploring
everyday objects around the house. After students have mastered
the basics of the simple machines they can move on to the tool shed
to see how these machines are combined to make more complex compound
machines by exploring such familiar items as a wheelbarrow, stapler,
and can opener. Weather, recommended for grades 4-9, offers students
the opportunity to forecast and predict the weather in an interactive
module that offers three levels of difficulty. Virtual Knee Surgery,
recommended for grades 7-12, allows students to take on the role
of the surgeon throughout a total knee replacement surgery. The
Teachers’ Guide offers tips for using the site, printable
activities to be used in class, and a listing of state and national
standards that are addressed in the modules. Included is a link
to interesting people to help students learn about professions and
career choices, lesson plans and glossaries of terms for each module.
