I do a robotics unit in my grade 4 class with Lego Mindstorm kits. They learn some basic programming concepts like loops and if-then statements. They love it, and in my experience age 9 is about the right developmental stage to start this. However, logical and critical reasoning skills can be taught at a much earlier age. Every child is different, of course, and some will be able to run with those concepts earlier, but that has been my observation.

From TFA:

...the extent of genetic diversity among hominins living one million years ago was between 1.7 and 2.9 times greater than among humans today

..and in the next paragraph:

Jorde thinks that the diminished genetic diversity one million years ago suggests human ancestors experienced a catastrophic event...

Um. What?

So, according to the research, 1 million years ago the human population was about 55,000 with a genetic diversity 2-3 times greater than that of modern humans. Can someone help me understand how they get to a near extinction conclusion? Is it just that the population is lower than expected? TFA is not very clear on the point...

Check with local schools. The one my girlfriend works at has a program where they take donated broken small appliances and let the students dismantle them to explore how they work. Once all the learning's been had out of an appliance, the parts are either given to the art department or to a local recycling depot.
