January 31, 2006 Essential Question: What are protists?
What are the characteristics of Plant like Protist?
Today we discussed the different types of algaes. They are euglenoids, dino flagellates, diatoms, green, red, and brown algae. Euglenoids can be autotrouphs when there is a light source, and heterotrophs when there isn't. Dino flagellates have plates, and can glow in the dark. Diatoms have glass like cell walls. Green algae can be Unicellular, multicellular or can live in colonies. Also known as sea lettuce, it is eaten in Salads. Brown algae are used as nutrients and as thickeners in food. An example of Brown algae is kelp. Last red algae can absorb light, and a substance called Carrageenan extracted from it can be found in icecream.
Then we worked in groups to create a concept map on Protists without using our textbook or notes. We will finish the map tomorrow in class.
The warm up today was #6. The questions were, What might cause red tide? When are red tides dangerous to humans?
The answer to the first question is when there is increase innutrients, and the second answer is some might produce toxins which get accumulated into fish, and then we eat them.

Today in class we worked on the warm up.
Warm up # 6:
How are red tides caused?
How are red tides dangerous to humans?
The answer to the first question is red tides are caused due to increase in nutrients.
The second answer is toxins get accumulated in the shell fish which might be dangerous if humans consumed it.
If you have not turned in your illustration from last week, your name was listed on the board. We studied Plant-like Protists (Also known as Algae) for the beginning of class. Mrs. Kulkarni gave us a list of all the examples of protists on the board, and we were given a sheet of paper to work on. In groups we were to make a Concept Map, or Mind Map, on protists illustrating all of the examples.
Today's homework was to bring colored pencils.

January 30, 2006 Essential Question: What are protists?
Warm up #5,
How are fungus like protist similiar to fungi?
How are fungus like protist similiar to plants?.
The answer for the first question is they are both heterotrophs , and they reproduce by spores. The second answer is they have a cell wall.
Today we reviewed plant like protist. As you know algae is the plant like protist. We also reviewed protozoans and fungus like protist.
Then we looked under the microscopes to find some protozoans. We actually saw amaebas, and paramecium move around the microscope! You missed out today if you did'nt see them.

January 27, 2006 - Essential Question: What are protists?
How does the amount of fertilizer affect the growth of algae?
We had a microscope quiz on Friday. Some students completed the lab on algae.
We finished up the articles :Had to read an article and make a picture of what the article is about. The picture needs to be colored. Also, we took notes on plantlike protists in the textbook. We will finish these notes on Monday.

Here are some notes on Molds(Fungus like) and Algae's(Plant like). They are #5 and #6 in your notebook respectively.
Table of Content:
1: Warm up
5: Fungus like
6: Plant like
This week we will review protozoans and molds. We will learn about Algae(Plant like Protist). We will also continue looking at the effect of fertilizer on the growth of algae.
We will look at different protozoans and algae under the microscope. It is exciting to watch the movement of these micro organisms.

January 26,2006 Essential Question: What are protists? How does the amount of fertilizer affect the growth of an algae?
Warm up# 3: What are the three types of fungus like Protists? The answer was Slime mold, Water mold and Downy mildew.
Today we did a lab with Pond water(algae). We used the clear bottles, and made a hypothesis . We wanted to see if fertilizer affected the growth of algae. We had to add different amounts of water and fertilizer to different groups of jars. The jars were divided into groups: A,B,C, and D.
We also looked at different articles today. You will need to make an illustration of what the article means. We will work on this tomorrow, in class.
The microscope quiz is tomorrow.

January 25,2006 Essential Question: What are protists? What are protozoans?
We did warm up #2 today. The questions are, what is the function of a contractile vacuole, and write the name of a protozoan with a psuedopod. The answers are, contractile vacuoles collect extra water and expel it, and the protozoan with a psuedopod is an ameba.
We discussed in class the three fungus like protists. They are mold, mildew, and slime mold. Mold lives in water, mildew live in moist soil, and slime mold lives on decaying trees. We completed 7-1 in the workbook up to plants like protists.
Microscope quiz is on Friday.
Bring clear bottles:Homework.

January 24, 2006 Essential Question: What are protists? What are protozoans?
Warm up #1 was given today. The question is what are the categories that protists are divided into? The answer is animal like, plant like, and fungi like.
We also discussed the four types of protozoans. The first kind is protozoans with psuedopods ( Ameba's). The second type is protozoan with flagella's. The third kind is protozoans with cilias, ( paramecium). The table of contents and warm up sheets were given.
Remember that there is a microscope quiz on Friday.

Today in class we completed warm up # 1. The question was, "What are the categories Protists are divided into?". The answer is plant like, Animal like and fungi like.
After the warm up, we talked about the four types of Protozoans (Animal like Protozoans). The first type is Protozoans with Psuedopods, such as Ameba's. The second is Protozoan with Flagella's. Third is Protozoan with Cilias, such as Paramecium. And last ones are the other Protozoans. The other Protozoans are usually Parasites. We were to take short notes on the section.
We read the chapter Ch 7: Sec 1. After reading the chapter we looked at Pond water, to find Protists.
Mrs. Kulkarni handed out our Notebook Quizzes. We recieved a new warm-up sheet and table of contents today.
Microscope Quiz on Friday.
1) Bring a narrow-neck bottle. (Such as a soy sauce bottle)
2) Bring Balloons.

We will start Chapter 7 on Monday.
What are Protists?
What are the characteristics of animal-like, plant-like and fungus- like Protists?
On Monday we will be talking about Protists and different groups of Protists. We will look at the Pond water and try to find some Protists.
On Tuesday we will finish studying all the different groups of Protists.
Wednesday is early release. We will talk about algae.
Thursday we will work on a lab: "Explosion of Life."
On Friday we will learn about Fungi.

While grading the test, I realized that some students are confused between Bacteria and Virus structures. Here is the table comparing Bacteria and Virus.
Tests have been graded and will be returned on Monday. The grades are on I-Parent. If you had not turned in your Vocabulary for Chapter 7, please do so on Monday.
