Video on how to use Chartle to create charts and graphs

A great graphic about the tsunami in Japan..

This lesson is about insects rather than parasites, but it teaches students about some insect parasites (e.g., mosquitoes and lice) as well as about insects in general. Students will see pictures of insects that bite and sting, and others of insects that don't bother people. They will classify insects into "likeable" and "not-so-likeable" categories and draw pictures of insects that people like and don't like.

Worms, worms, worms! Classroom activities for K to 8!

How to integrate the NOVA Design a Parachute interactive into the classroom: In this activity, students assume the role of engineer as they design a parachute that will slow the Mars Explorer Rover as it lands on the surface of Mars.  I like the authentic feel of this activity, students are led through the thinking process of an engineer as they consider all of the requirements the chute must meet before they begin designing. Approach this interactive as a class using an interactive whiteboard or projector-connected computer.  As a class, get "briefed" on the requirements for the parachute design.  Discuss how these requirements may impact the parachute design.  Treat this like an actual briefing and encourage discussion (all ages like to pretend!).  Before students access the interactive, ask them to sketch their thoughts about parachute design.  This lets them think through the design apart from the pre-determined categories presented in the interactive. Students can design and test their parachutes individually in a one to one computer lab setting or take turns designing and testing in a computer center lab on classroom computers. Debrief after the interactive to discuss the parameters that were the most successful and what students learned about volume, drag, strength and stability. Extend this activity by creating a mock-up of the parachute they designed online.  Find a high place on the playground or in the building where students can test these parachutes.  What did they have to adjust for an Earth bound parachute? Tips: The NOVA page has a great introduction paragraph about how engineers approach a problem.  Be sure to read it with your students!  Encourage students to learn more about the Mars Explorer Rover before designing the chute.  It may adjust their thinking!From I Learn Technology blog

Planet Pals: An environmental site for students: Nature themes, foodchain, habitat, seasons and more. 

NASA has created a great new site for kids to learn more about Earth, the Solar System, The Universe, and much more. Within each section of The Space Place, there are games, activities, videos, interactives, and a wealth of information written so that kids will grasp it.
