Cell city analogy homework due tomorrow.

Cell Membrane notes

Cell Membrane Demonstration - Next Day

We looked at the cell membrane demonstration today.  The iodine had permeated through the baggie into the cornstarch.  This was evidenced by the purple color that showed that the iodine reacted with the starch.

Final Egg Observation

After soaking the egg in vinegar and then corn syrup, we put the egg in water over the weekend.  This is what the egg looked like today.

Cell Membrane Demonstration

We set up a demo today using cornstarch and iodine.  Students made a prediction about what they think will happen.

Egg Observation - 3

Today, we took the egg out of the vinegar and made our after observation.
The egg had clearly "deflated" from yesterday.  The liquid had a strong vinegar odor so we put food coloring in to see the difference between the liquid on top and the corn syrup.

We put the egg in water.  We will observe the egg again on Monday.

Egg Demonstration - Observation 2

We took the eggs out of the vinegar to find that the vinegar had begun to dissolve the shell.  The egg had begun to absorb the vinegar and increased in size.
We took the egg and placed it in a cup of corn syrup.  Students made a hypothesis about what they thought would happen to the egg in the corn syrup.

Cellular Respiration Lab

Students discussed what cells need to live.  We discussed how cells need oxygen.  We did an activity to show how we breath out carbon dioxide.

Cell Membrane - Egg Demonstration

Today, we started an egg demonstration to show how the cell membrane works.
The students made observations and a prediction about what would happen to the shell of the egg when the egg was placed in vinegar.

Versatile review for the summative

Cell lab with microscopes

Monday and Tuesday we looked at cells under the microscope.  We looked at onion cells (with and without stain), cheek cells, and blood cells.
Students have observed and can now understand that living things are made of cells.

 Onion cell without being stained

 Onion cell with Stain                 

 Blood cells                                 

 Cheek cells                               

Microbe Lab/Virtual Pond Dip

Wednesday and Thursday will be a split class.  Half of the class will be using microscopes to look at pond water samples to see microbes and the other half will be completing a virtual pond dip.  The next day, students will switch places.

Students will be using the class website to access the virtual pond dip, njhs7science.weebly.com

Under resources, you will find cells and biology.  The last option is pond dip, http://www.microscopy-uk.org.uk/index.html?http://www.microscopy-uk.org.uk/ponddip/

 Students need to complete the worksheet for the virtual assignment.
