[Nfb-science] Need Guidance: Several Heavily Visual Labs Coming Up

[Cindy Robinson]

Hi. I am a V I teacher. For the tree rings, you need someone to carve out a little line at every yearly ring. You can differentiate the two kinds of wood by burning the denser wood with a little wood burner and carving the spring wood at an angle to mark the ring. I really hope someone can do this for you. Ask for someone at Project Learning Tree for the state department of forestry. The state department of forestry will usually burn and carve wood for you. They promote the study of forests. Good luck. And if you want me to, I will do it for free if you are allowed to give me your college address and specific professor. I will mail it to him. We call them "tree cookies." I am a member of Project Learning Tree here. cindy robinson 
 
spring wood is laid down early in the growing season and tends to be lighter and more porous than summer wood which is laid down later in the growing season and tends to be darker and more dense. 
 
I will look over the rest tomorrow.

Subject: [Nfb-science] Need Guidance: Several Heavily Visual Labs Coming Up

You probably know that during the past quarter, I have been taking an environmental science course at my local community college for a General Studies degree. I'm in the second course in the series, and there are a number of labs coming up that either use chemicals, or are heavily dependent on measurements. I don't know if the lists accept attachments, but I felt the best way to give people an idea of what these labs are like is to send the information about them that I've gotten from my instructor. The instructor and I are not sure how to deal with these labs, but I figured that if you got a look at them, you could give me some ideas on how I might be able to participate and not just sit on the sidelines. So if you have any ideas on how I might deal with these labs, I'm all ears. Thanks.
