Scientists demonstrate what tree rings tell us about the change in climate over time and how the climate changes in cycles.

Here is a handout to give students when they are about to do a science experiment.  It will help them focus on the procedure of the scientific method.

Students can either label or put the skeleton together in this online activity.  The better they do the higher their score.  They can practice it as man times as they want.

This animated cartoon about eyes also comes with a quiz, an article, a labeling worksheet, and a word find.

This video visually discusses what ecosystems and biomes are. The video is 16 minutes long.  It talks about the 7 major biomes on Earth, arctic, coniferous forest, deciduous forest, desert, grasslands, aquatic, and the rainforests.  Permafrost and savanna are also discussed.  At the very end of the video, the narrator demonstrates how to make a terrarium.

This is a visually appealing and dramatic video that introduces your students to the study of biomes.  This is a great video to show as you get started on a new unit of ecology.

In this video, the definition of an ecosystem is visually demonstrated and discussed as well as the different biomes.  This is a good introduction to your unit on ecosystems and biomes.

This TEDEd video discusses five parasites and how they affect the host's brain.  The parasites it discusses are the Gordian Worm, Rabies Virus, Ophio-Cordyceps, Plasmodium, and Toxoplasma.  Each one of the parasites has a unique way of getting the host to help it reproduce.

Mr. Edmond sings a good song about the difference between Mass and Weight.  He actually has a nice voice.  He holds up signs so that you can karaoke along with him.  I think I am going to try and karaoke with a couple of students about mass and weight.  Should be fun.

This Study Jam video uses two cartoon characters to describe the processes of weathering and erosion.  The content and scientific explanation is great and created with young children in mind.
