WOW! Thanks all for your many suggestions. My grand-daughter is coming this afternoon for her first "lab". Based on what I saw here, I'll be extra careful to see what makes excited and then have her try some simple things. Maybe she'll build the first robot to explore some alien world (like my workshop!).
