Where do I fall? I would say that the second group - getting all the things ready to do experiments at home and then actually taking time to do them is really time consuming, but ... kids love it.
So what can I do? From time to time I do need to turn my kitchen into a lab and let them grow crystals, burn sugar, make lots of bubbles, sift sand, magnetise needles etc. As a child we never made any experiments at school, so now I am learning and enjoying the hands-on-science with them. It is a lot of fun, so just take your time and ... do it!
