Inquiry U.V cards

Mrs Leishout told us she had a present for us we knew it was something cool. Is it a pen drive? I bet it is those Inquiry books? No its something way groovier than that! She sat us down on the mat and showed us what the present was. I did not now what it was it first she told us to use them so you could collect data for our inquiry. They were called U.V cards! We took them out side, and counted to twenty.Then and the white strip changed to a very light purple that’s means it was low if it was darker then it would have been a high we think that they are pretty cool because they tell you if you need to slip slop slap and wrap!
