Field Notes
We were happy because it wasn't to cold outside and it was very calm. It was 44°Fahrenheit outside with a weather cast of cloudy. We were outside of the Skillin School black top on the road that's connected to it. The hard part about it was trying not to get pricked by the giant thorns while trying to collect samples to take pictures of. We were very surprised on how big the thorns were. We were looking for the rosa multiflora or the multi flora rose. What Riley did to sketch was leaf rubbings. We think found it because the thorns were curved and large and the leaves were alternate and toothed.

Great leaf rubbings!

You've provided good evidence that you found multiflora rose. If you think those thorns are large, you haven't run into our native hawthorns!

In writing scientific information, it's very helpful to be exact and complete. For example, you noted that "it was toothed". If you had written "the leaflets are toothed", then someone would know what you meant, even if the photo wasn't available.

Your photo whose caption reads "it had little hairs on the back of it" is the one piece of evidence that convinced me you had found multiflora rose. And ... that's another statement that could be more exact and precise. Just for the record, everything in botany has a name! For this one, you might write "each of the paired stipules located at the base of the compound leaves bears a fringe of hairs". You're gong to love botany!!
