Since you already have field guide books and your daughter has an interest and better understanding, doing a transect is quite an easy practical to do for you both to incorporate into a walk or to do from the top to the bottom of a hill but it can tell a great deal about how the kinds of insects and other invertebrates vary and how they relate to the land and the plants around them. It requires a small bit of kit but as you say you learn by seeing things yourself this may help you too. Seeing as your daughter has a fair bit of knowledge this may be good to get her to begin putting that knowledge to use and get her to make observations and draw conclusions from those herself. I'd do a short walk as you can end up with loads as one university field trip showed when I did this; a whole day spent at a dissecting microscope left me seeing bugs before my eyes!
Basically pick a walk where you have access to vegetation and there is a gradual change in the kinds of vegetation for example from a sandy beach, onto the dunes where plants are becoming more common and if it leads to wooded land then all the better. A hill is good as you will see that the vegetation and exposure is very different at the top of a hill to the bottom of the hill. The kit you need is a sweeper net, you could probably make one yourself, loads of small bottles or containers with lids and some labels to mark them up with, a pooter again another thing you can make quite easily and a notebook and possibly a plant guide book. To examine the insects a good magnifying glass and a craft lamp will do and some tweezers or something to sort the insects out with will help. You need to do this when it is dry and the grass and vegetation is dry as you end up with loads of just bits of insects!
You go along your walk and at chosen points from the start to the end of the walk you sweep the net around whatever is around you at each point, so if you have bracken, sweep the net through that for a little while, a minute would be the maximum and then collect the insects in the net using the pooter into the little containers. Close the containers up and mark them up and put a note into the notebook about where you collected the sample; where it was, the sort of vegetation around, the exposure etc. I think 4 or five points would be a reasonable number to start with as you will end up with lots of insects to sort but just be selective about where to sweep; you won't see much in the way of different results if you sweep twice in very similar spots. Once you've done your walk then you get to examining your finds.
With examining the contents of the insect bottles start with one from the start of the walk and using the notes, a guide book to insects, the magnifying glass, something to do the sorting on, craft lamp and tweezers you just sort the insects into similar types, if you can you could do species if you can easily identify them and make notes on what is found, how many and what each insect does and their characteristics; so for example you have bugs which have sucking mouthparts so they will feed upon certain things compared to flies, bees, wasps and other insects. You do this for each point you collected insects and in the end you can compare the vegetation at each point, the insects found at each point, how many different kinds of insect found at each point to see how the diversity varies and quite a lot of other things. It can take a bit of time so it is worth storing the insects in some alcohol to preserve them if you can't get to this on the same day as the walk.
Phew, it is easier than all that text makes out and the internet might give a better summary of that.
