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.

Students will draw and diagram the different phases of the moon depending on how the Earth, Sun, and Moon are positioned relative to one another.  Students also get a chance to practice the moon phases and their names.  Finally, they get to demonstrate their understanding by drawing their own moon phases.

This "Its OK to be Smart" video discusses why our bodies feel cold.  Students will learn that it is all about heat transfer.  The video will discuss convection, radiation, conduction, temperature, thermometers, matter, atoms, The Second Law of Thermodynamics, and why we would freeze in space.

This "It's OK to be Smart" video discusses the human nose and its awesome ability to sense smells.  Please note that this video does talk about human sperm so you need to judge your students' maturity level.  Nerves, olfactory receptors, eyes, and ears are also discussed in the video.

This video discusses the science and culture of being left-handed.  This would be a great video to show a class with a good percentage of lefties.  

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.
