this weeks experiment

During this week, i learned how to make an experiment by making an observation. In the past experiments that i have done, i came into class wondering what something did. Now, i interacted with the cockroaches and came up with a question. I observed that they stuck to dominics hand so our group came up with the question: what can they stick to.

At camp spears, i learned about:





Bogs


Bogs are very deep watery places. The water has no oxygen so bacteria cant grow there. Bacteria decomposes things so nothing can be decomposed. Something that falls in a bog can be preserved for a very longtime. In England, they found a thousand year old man that was sacraficed and thrown in a bog. They found out all this stuff from the things in his body that were preserved.



Symbodic relationships

Symbiotic relatrionships are when a living thing uses aanother living thing to live. For example, fungus grows on alge. The fungus needs alge for nutrients to live but the alge can live on its own.

Fox dung

Kinda gross but the fox eats hairy animals and poops out hairy poop. I didnt know the hair would show up.

Archery

I learned that archery is hard when you dont do it for a while. I did archery last year or so and when i did it it was really hard. My fingers were numb when i fired the arrow too.

Pond Ecology

I liked pond ecology because it was something that i havent done before. I liked to see what was in the pond like crayfish and salamanders.

ThE WeEk Of 4/1

This week in science we finished our prodjects on reebops. We started an experiment on cockroaches and made observations about what we noticed about them.

I noticed that they have small heads, suctionlike feet, and have a hole between there shell and there belly ex:

On thursday, we had our test. I thought it was easy but it took a long time for me to finish.
