Where does the ‘stuff’ in trees come from?

learner.org is an interesting site which “uses media and telecommunications to advance excellent teaching in American schools.”

One of the issues they address is the area of misconceptions in Science.
This is a wonderful video which asks where does the material that makes up trees come from.

College graduates from Harvard and MIT were asked and not one of them gave the correct answer. In fact their answers were very similar to those given by six year olds.

It makes us question what other serious misconceptions we are responsible for, and leads us to question what and why we are teaching.

If we put together the ten most important ideas in science, how many of them are emphasised in our science courses?

College students answering these questions kicks in at about the 8-minute mark.

A primary school kid gets a look at solid air (dry ice) at 53:20. The look on his face is worth waiting for.
