Every day I learn in NS I have more to bring back to you all in MN! Today we began laying traps for the white-footed mouse using Longworth Traps. The data collected this week will illustrate the population density of this species of mammal in the area. The scientists will then compare this data to other years that they have done the same thing. When they consider the temperatures at the time they can begin to determine how the changes in climate have effected the population. Why do you think this matters? There is something called "interdependency" amongst the species here (and everywhere). What do you suppose this means? Do you have any idea why this is an essential action for scientist studying climate change and its effect on the mammal population in NS?
Next watch my video which goes through the steps I took in helping to set up the traps. (check out My YouTube: http://www.youtube.com/watch?v=FDqpXlClJTw)
Math Challenge: My group placed Longworth Traps at 10 locations along a 100 meter stretch of a hectare. There were five groups named A through E. If each group were spaced out equidistant from one another on a 100m wide grid and they each started walking a 100m parallel path from one another setting down traps at 10 locations, about how far apart would each trap be placed from one another if they were all spaced apart equal to its neighbor? How many traps were set out? Use the notes I took and placed here to help you! If I told you that there were actually two traps at each drop point how many traps would you say were dropped?
Work together, come up with a response and defend your answer! Then ask me something you want to know about what I'm doing and I'll do my best to follow up with a response!
II only!

Tanner thinks that you found rabbit poop and that it won't scare away the mice. We also think you will catch 3 mice - but the whole group will catch 9.
What are the predators to the mice?
I think that the poop that you found had a sweet smell because it dose not happen with people alot but sometimes what you eat can change the smell of poop.So if they eat apart of a tree that smells good and it comes out with there poop that changed the smell.One thing i was woundering is why where you guys holding the poop because even though it smells good there could be something bad in the poop that you do not know about.
We found out the meaning of interdependency: it's an adjective
of two or more people or things dependent on each other: the increasingly global nature of human society, with interdependent economies.
We found the meaning in the dictionary on the computer. The Wildlife in our world works together in a way that keeps the population of different species under control so one animal won't dominate over the other, but in Nova Scotia the deer population has been introduced into an unnautual habitat and has increased over the years so much that the moose population has dropped incredibly over the years. Are there other animal species that have been increasing and decreasing? If so which species?
Interdpendency means (of two or more people or things) dependent on each other : the increasingly global nature of human society, with interdependent economies. We think that this is essential to scientists working in the field because, the scientists depend on each other to take down notes and sketch in case one person is looking at something and doesn't have time to observe and sketch until later.
INQUIRY:
What animals have you seen/handled so far? Do you know what kind they are? What are some specific things you have observed? What is your favorite animal so far? What is your favorite part of the trip so far?
We found the answer to your math problem:
The length between the traps is 25yds apart.
100 traps were set out.
250 divided by 10=25.
So our answer was 25yds apart from each trap.
Koleton's concern is that the trap looks different from the rest of the forest so "it will be harder to get mice. But the food should help get them there." Koleton wants to know if you try and keep the rabbits away from the traps, and if so how?
The scat
I think the scat you found while putting your trap up is the eastern cottontail rabbit because there scat is brown small and round. And it has small pieces of grass in it.
