It's all about attraction.  This video discusses covalent and ionic bonding as well as the more basic structure of atoms and molecules.

This math resource contains 36 numbered boxes that can be used during assessments.  This allows students enough room and the ability to keep track of problems solved during math assessments.

Students have a difficult time actually understanding how big or small planets are or the distances to and from planets compared to other terrestrial bodies in space.  This video does a great job comparing both size and distance and will help students with their spatial reasoning.  How small we are compared to the universe?

This is a reading of the Declaration of Independence by Hollywood actors and actresses.

In this video pedestrians in a park are asked why a hard drive and a book sitting at the same temperature have a different temperature feel to them.  The hard drive feels colder than the book.  He then takes an aluminum plate and a plastic plate to see which plate melts ice quickly.  Even though the aluminum plate feels colder, it melts the ice quickly.  This is a good experiment to try with your students.

Here is an excellent video about how scientists map the human genome. Adenine, Thymine, Cytosine, Guanine, Tissues, Organs, Organism, DNA, and genes, are keywords that are used in the video.

This video visually describes how cells use active and passive transport to get molecules into an individual cell. Osmosis, Dialysis, Facilitated Diffusion, Membrane, ATP, Protein Carrier, Iodine, Endocytosis, Phagocytosis, Pinocytosis, Lysosome, Exocytosis are key terms that are used in this video.

In this science lab, students will gain a pretty good understanding of what mass, volume, and density are. They will digitally change the volume of objects, weigh different object masses, and calculate the densities of each object. Students will use the computer and the Phet Simulation software to complete this lab.

This science lab can be used in any of the science disciplines because it is going to help students learn how to read a meter tape. Students will learn what the Magnus Effect is and how to demonstrate the Magnus Effect by "flying" a hollowed-out "Bic" pen across the classroom. Students will also learn how to create a spreadsheet and then add a formula that will automatically calculate the average of their pen flight distances. I use this lab at the beginning of the year to get students excited about science as well.

This video discusses symbiotic relationships. It does a great job detailing the relationships between symbiotic organisms, mutualism, commensalism, and parasitism. As part of the discussion, the symbiotic relationship of the clownfish and sea anemone is explored.
