Photosynthesis

Today in science we introduced our new unit on Photosynthesis.  Photosynthesis is the process by which a cell captures energy in sunlight and uses it to make its own food (a type of sugar called glucose).

As a class we focused on a few key terms to know when learning about photosynthesis such as autotrophs, heterotrophs, pigments, chlorophyll, and stomata.

Tomorrow, we will start to dive deeper into the the process of photosynthesis.  The reading for tonight will help reinforce our new understanding of how organisms get energy.  The reading will also introduce the two stages of photosynthesis.

Here is the link for the reading from our Science Explorer text.

Here is a great three minute video from Discovery's "Greatest Scientific Discovery" series that will introduce the experiments that enabled Priestly and Ingenhousz to "discover" photosynthesis.

Introduction of Active Transport

Essential Question:  Give 3 examples of diffusion in everyday life.  Sketch one o these examples and show the high and low concentrations and movement of the molecules.

Today we were introduced to the second form of cell transport, active transport.

We will use a worksheet to frame your work today in the reading on passive and active transport.
Click here to access the document.

Active transport is when energy is needed to be used to move molecules from low concentration to high concentration across a cell membrane.  Often in this form of transport, transport proteins are used to aid the process.

Here is an image of active transport.

Here is a link comparing of active and passive transport.

Here is a video showing active transport in terms of the sodium/ potassium pump.

Cell Transport Introduction. -

Today we will be starting a Unit on Cell Transport (active and passive).

Essential Question - How do the necessary materials get in and out of your cells.

Here are the notes from today's class.  Click here to access.
Today in class we will add to these notes filling in examples of each of the vocabulary terms from demonstrations performed in class.

Here are some interactive links showing diffusion of molecules - a form of passive transport.

Meiosis vs. Mitosis

When you are done your DNA models, check them with a teacher and then start work on the Mitosis vs Meiosis 
Webquest below.
Mitosis and Meiosis Comparison Worksheet

After you have completed the webquest view a few of the below videos.  Pay close attention to the following:
1. How many daughter cells are found at the end of each cell division?
2. What is the function of each division and which cells do they occur in?
3. How many chromosomes are found in the daughter cells compared to the mother cells?
4. How many divisions and interphases does each go through?

The following is a link to a reading on DNA's structure and composition.

The Guide- DNA's Chemical Composition and Structure.

Here are two images of the make-up of DNA.
In both of these images you can see the "ladder" sides are made up of a sugar and phosphate, where the central rungs are made up of nitrogen base pairs (A,G,T and C).

We will be constructing DNA models using one of the three methods:

• Bead Jewelry
• Origami or
• Candy

The point of the activity is to be able to correctly identify the smaller parts that make up a strand of DNA.

Cell Division- Mitosis

Here is a great image of mitosis.  This is much like our text book but do not worry about the "Prometaphase."

Mitosis is the process of cell division for eukaryotic cells found in multicellular organisms.  All cells come from existing cells and mitosis is how most cells divide. The only eukaryotic cells which do not divide by mitosis are sex cells a.k.a. gametes a.k.a sperm and egg cells. 

Here are some videos that introduce cell division- mitosis.
