3 DNA: Spot the difference

Here we look at DNA, the molecule which contains the instructions for making each living creature. It is contained within the genes of every individual living thing on Earth. Closely related creatures have DNA that is very similar, and distantly related creatures have DNA that is very different. By looking at how similar or different their DNA molecules are, we can see how closely related two species are.

What is "Computer Science" ?
Hal Abelson gives an introduction to the "Structure and Interpretation of Computer Programs" lecture with an explanation of Declarative and Imperative programming.

Excerpted and adapted from Hal Abelson, "Introductory Undergraduate Subjects in Computer Science":-
6.001 differs from typical introductory computer science subjects in using Scheme (a block-structured dialect of Lisp) rather than Pascal as its programming vehicle. The subject's developers feel strongly that Pascal

Sticks and Stones Will Break That Bone!
Students learn about the strength of bones and methods of helping to mend fractured bones. During a class demonstration, a chicken bone is broken by applying a load until it reaches a point of failure (fracture). Then, working as biomedical engineers, students teams design their own splint or cast to help repair a fractured bone, learning about the strength of materials used.

How Tall Are We?
Kindergartners measure each other's height using large building blocks, then visit a 2nd and a 4th grade class to measure those students. They can also measure adults in the school community. Results are displayed in age-appropriate bar graphs (paper cut-outs of miniature building blocks glued on paper to form a bar graph) comparing the different age groups. The activities that comprise this lesson help students develop the concepts and vocabulary to describe, in a non-ambiguous way, how height
