Activity 46-47 Reducing Risk

Today students tested Henry for bacterial growth. Students selected two different places to test. We used agar in a petri dish to grow bacteria. Students used the scientific method and made hypothesis of where they thought the greatest amount of bacteria would grow. Students taped their petri dish closed and we will observe and analyze data.

Homework: Science Fair due on block days! Flip charts due next Friday!

Activity #45: 5 Kingdoms of Life

Today students examined the characteristics of the five kingdoms of life. Students first began by reading about microbes and their characteristics. As students read they filled in the inner conversation chart about what they noticed, what they wonder about, what they found out, and where they got lost. Next, we made a chart of the five kingdoms and put the characteristics of each kingdom into the chart. Then students made a flip chart of the five kingdoms.

Homework: Finish five kingdom flip chart and work on Science Fair

Hint: Quiz on Friday!

Activity #44: Classification of Microbes

For the first part of the day students went to their CSAP testing rooms and took the writing benchmark test. After the test was done, students attended periods 1-4. In science class, students practiced classifying microbes. They started of by looking a different cards that had information and pictures of specific microbes. Then as a group they sorted each microbe into a group according to a specific characteristic. Next, students were given a information card to each of the five kingdoms of life and a virus card. There job was to revise their groups into one of the kingdoms or virus groups. They wrote their final groups in their notebook.

Homework: SCIENCE FAIR!!!!!!!!!!!!!!!!!
Honors Class: Cell (favorite place) Drawing

Hint: There will be a quiz on Friday over the 5 Kingdoms of life!

Unit C Quiz4

Today students took a quiz over the structures and functions of the cell's organelles. The answers to the quiz are: Plant cells have cell walls, chloroplasts, and a central vacuole which animal cells do not have. The mitochondria is used for cell respiration, the nucleus is the control center of the cell, the cell membrane protects the cell, the cytoplasm is the jelly that holds all the organelles in place, and the chloroplasts carry out photosynthesis.

Homework: WORK ON SCIENCE FAIR (DUE IN LESS THAN TWO WEEKS)
Honors class: cell house diagram

Activity #43 Protists and Bacteria

Today and tomorrow in block classes, students will be observing protists and bacteria under the microscope. Students will focus slides to look at characteristics of both microbes. Next, students will draw pictures of the microbes in their science notebook. Then students will complete a Venn diagram of protists and bacteria. Finally, students will write a summary of the similarities and differences between protists, bacteria, and human cells.

Homework: Study for organelle quiz on Friday!

Activity #42: A closer look

Today students started their new notebooks. We set up our table of contents and started activity 42 on page 4. Next students watched a power point on the organelles that make up a cell. As they watched the power point, they filled in a chart that had the structures and functions of each organelle. Finally students recorded their quiz grades on their ELG tracker.

Homework: Study for structure/function quiz on Friday!

Due Today: Make sure to have your new notebooks here!

Activity #40: A CELL MODEL

Today students participated in a cell membrane activity. We first reviewed what the cell theory is which states that all living things are made up of cells. Next we talked about our two new words: Cell membrane and cytoplasm. Next we made a model of the cell membrane and cytoplasm. Students watched as the white cornstarch turned purple and the orange Lugols stayed orange. We then discussed the possibilities of why this happened. Finally, we found out that only the orange molecules can travel through the bag(cell membrane) while the white cornstarch molecules were too large to go through the bag. This represents how the cell membrane works. It protects the cell by allowing some molecules to cross the membrane and keeps other things out.
