Homework and Cells

Nathan's Scribe Post for Tuesday, May 24

The first thing we did today was discuss the homework assignments we had and when they were due. Our homework is to:
  • Do a reflection post after posting your scribe post (Due May 31st)
  • Our last blog comment (Due May 31st)
  • Cell Project(Due May 31st)
We also have a cell quiz coming up next week, and the rat dissection is taking place on June 7th.

For the Cell Project, what we have to do is use everyday objects to create a representative model of an animal cell or a plant cell. For each organelle, we need to choose an object that symbolizes or represents the organelle’s function. Next, we create a table which lists each organelle you have represented in your model. For each organelle, state its main function. For more information about the project or the rubric, it's in grade 7 science, on moodle. It's a word document at the bottom of the page called "Cell Project".

What the Table is Supposed to Look Like

After the homework discussion, we mov
ed into cell diagrams. First, we had to take out our highlighted "Building Blocks of Life- The Parts of a Cell" sheet (also on moodle). After going through each part of a cell, we color-coded each part with a different color for each. Then we each received two sheets with two different pictures on them. One had a picture of a plant cell, and the other with an animal cell. Our job was to label it and use the color-code we created to color that part in the picture.





The things we had to label on our diagrams:

  • Plasma/Cell Membrane
  • Cytoplasm
  • Nucleus
  • Rough ER (RER)
  • Smooth ER (SER)
  • Nucleolus
  • Ribosomes
  • Golgi complex
  • Golgi apparatus
  • Mitochondria
  • Vesicles
  • Vacuole
  • Lysosomes (Mostly in animal cells)
  • Cloroplast (Only in plant cells)
  • Cell wall (Only in plant cells)

Here is a cool animal cell labeling game! See how well you know your animal cell parts.

Here is a cool plant cell labeling game! See how well you know your plant cell parts.

Emilija is the next scriber!

Cern and Cells



Hello everyone,

Yesterday May 17th we learned about cells and CERN. Cells are the basic unit(structure,function) of every living thing. Ms.D asked us how do we know if we are alive? Many of us had different answers but most of us said by movement. Ms.D said that we know if we are alive by movement, respiration, reproduction etc. There are 6 kingdoms Animalia, Plantae, Fungi, Protist, Monera, and Archaebacteria. Animalia is the animal kingdom. Plantae have cell walls that are used to protect the plant, and chloroplast which makes the plant green. Fungi is where the mushrooms and other fungus go. This kingdom decomposes waste my teacher from Ecuador told me they kind of recycle a big part in nature.
Monera is where bacteria fall into. They told me that most bacteria is actually helpful to your body.In my other school they taught me that archaebacteria was part of the monera kingdom but Ms.D said that it was separate kingdoms. Archaebacteria is bacteria that live is extreme environments.




Large Hadron Collider
this is what the hadron collider could affect us.The Large Hadron Collider at CERN near Geneva, Switzerland will open new views on the deepest secrets of the universe, stretching the imagination with newly discovered forms of matter, forces of nature, and dimensions of space which it is pretty cool and we could advance greatly in technology. Then we saw a couple of videos about the hadron collider and a presentation. We also saw a funny video of some people that work there and made a rap song. We are going to Geneva, Switzerland mostly because of the Hadron Collider. The Large Hadron Collider, or LHC, is a facility at the European Center for Nuclear Research (CERN) on the French-Swiss border. It is designed to take particles at high energies and smash them together, to see what results are obtained. This Machine is huge and amazing, also with this machine we could do black holes which they are awesome.
