Wednesday- Tuesday Big Lab!

WAKE UP WE'VE GOT MORE LAB TO DO!

So to start of here are just a couple of photos of just a few of the 9 lab stations. You have station 5's radish plant were we learned about how the sunlight effects the plants growth. In this case the plant will actually tilt itself towards the light. Also in station 5 there was the corn. The corn showed the effect of gravity on a plant and its roots. Roots alway grow down because of gravity so when looking an the sideways corn seeds all the roots are trying to go

Your next picture is of station 3. In station 3 we learned all about nonvascular plants like mosses. So we studied four different types of mosses as well as reading about nonvascular plants in the textbook. The next picture is of radish seeds in station 2. We put these under microscopes and viewed the tiny thin white hairs that came out from the root. We decided that the hairs were used for efficiently getting more water and nutrients by creating more surface area as well as helping the plant stay grounded. So there is a very small short overview of just a couple of the labs. And heres a review of what we (or what you should have) learn!

REVEIW

You should know.....

• how to identify the Zone of Elongation found in the Meristematic Zone
• What the difference between Vascular and Nonvascular plants
• ----------What each has and doesn't have
• How gravity effects plant growth
• How sunlight effects plant growth
• ----------Temperature and position
• Difference between Dicot and Monocot and how to identify them

Hopes this helps with the studying. The homework was just to finish the lab and 4 questions on the first two pages of 23.5

AND the next scribe is ....... JORDAN! Love you!

Immunity Monday

Hey everyone sorry for posting way to late, but here is your recap of our Monday class.

We finished our two labs about bacteria that we had started on Friday with Mr. Peck. For the first lab we had swabbed different areas around the class room and some groups even went around the school. Each group swabbed an area and tested for bacteria by putting three different area swabs in a petrie dish and leaving on section blank as a control, but we had to wait over the weekend to find out the results.
For my group, we tested the floor of the classroom, the top of teh germ-x container, and a sink handle. WE found there to be the most bacteria on the sink handle which is quite surprising because the floor is very dirt and was our hypothesis for having the most bacteria.

The other lab we finished on Monday was about antibiotics. We put peppercorn broth on a petrie dish and put on that same petrie dish three different antibiotic discs and then another blank disc as a control. After waiting we got to see the results today.
For my group, we found the neomycin was strongest against the bacteria, having a bigger diameter of non-bacteria around it then the other antibiotics.
Today we also had our Disease of the day.

Today our disease of the day was Malaria.

Malaria
-The agent of disease is protist
-transmitted by mosquito bites
-attacks the human liver
-prevented by bug repellents and reduction of standing water

Homework...
- finish UP 13-18
-read section 35.2 and 1st page of 35.3 about immune systems and use the note taking skill tree maps
-- Due Wednesday

An Exciting and Awake Thursday

Well in all honesty this Thursday wasn't very busy, but here's what we did do.

First, we took notes on 6-3 Biodiversity and looked at charts. Some of the main points and ideas were
-all species are involved int the food web/chain
-Threats to Biodiversity
--pollution
--global warming
--resources
--habitat destruction
--hunting
--disease
--invasive species
-pollutants increase the higher it goes on the food chain

Then we watched part of a 60 Minutes video called The Wasteland. It was about ewaset which is waste like old cell phones and computers. This waste sometimes gets shipped illegally out of the country. These places have they highest death rate from diseases like cancer because the materials in cell phone and especially compute monitor, which hold terrible chemicals like mercury. So, when these ewaset products are burned and taken apart the people who do this dirty work are infected and become sick. Some even die from the chemicals involved in this work.
Hopefully we will finish the video tomorrow because it was really interesting and anyone who missed it really missed out.

The homework, like always, can be found on moodle under Stein Bio. and click the calendar, but just as a heads up the Oil Spill movie project must be posted on the blog by 8AM tomorrow. So I would post those tonight. And thats your Thursday recap! Thanks for reading!

And the next scribe for Friday is MattT! Have fun Matt!
