Chia Pets

Today in class we finished making the chia pets. Students who had finished the pets on Friday could see some growth on their pets. Hopefully in a few days all chia pets will be covered with grass. We have placed the pets in different locations to see the effect of light on grass growth.

In class we talked about Photosynthesis and students made a KWL chart which is #6 in their notebook. They also took 2 column notes on Photosynthesis (#7 in their notebook).We will talk about respiration and compare and contrast it with photosynthesis.
Warm up #4: Transport by proteins is an example of_______transport.

Chia Pets

We discussed Active and passive transport in class today. We will soon start our studies on photosynthesis. Students will be making their own Chia Pets in class on Friday to study photosynthesis. Students need to bring in used or new pantyhose or Knee-highs and any decorative items that can be used to decorate their pet. Items include buttons, pom-poms, googly eyes, pipe cleaners, beads etc..

Tuesday(September 19th)

Today in class we talked about the purpose of the "Eggcellent experiment". We continued our discussions on cell processes and the importance of Osmosis. We defined Osmosis and diffusion and then worked on the Vocabulary words from Chapter 2:Sec 1.
Osmosis and diffusion are examples of Passive transport. Tomorrow we will continue defining active transport and list some examples.

Notes on Osmosis and diffusion

Diffusion is movement of molecules from higher concentration to lower concentration.
Example: Air freshner

Osmosis is diffusion of water molecules through a selectively permeable membrane.
Example: Root cells transporting water to the stem.
Egg absorbing water during Eggcellent lab
Watering of carrots when salt was added to it.

Osmosis and diffusion are examples of Passive transport(Transport that does not require energy).

We also talked about chemical compounds.
Chemical compounds are of two types
1: Organic compounds: Compound that contain carbon
Ex. Proteins, Carbohydrate, Lipids, Nucleic acids
2:Inorganic compound: Compound that does not contain Carbon.
Ex. Water, Salt, Carbondioxide(exception)

Monday: September 19th

Students will be writing a lab report in class on the "Eggcellent eggsperiment".Students will need a graph paper to show the effects of different liquids on the size of the egg. If they finish and have time they can read a science article and summarize it.
Some students have been given an opportunity to finish the writeup at home and it is due tomorrow. Students are required to read mininmum of 15 different science articles in class by the end of the year. Articles are provided to them in class. They will summarize their articles in their composition books.

Eggcellent experiment lab report.doc

We will start discussing Osmosis and diffusion:Ch 2. Students should be able to define the words and understand the difference between them. They are encouraged to read the chapter at home.

Wednesday is early release and we will be discussing organic compounds. We will then look at photosynthesis and respiration.

Eggcellent Eggsperiment

Standard Element: S7L5.1.a
Explain that cells take in nutrients in order to grow and divide and to make needed materials.

Students have been working on the eggcellent experiment since Friday, september 8th . We soaked the egg in the vinegar, followed by plain water,colored water and sornstarch water. Students have been recording the data and observing the effects of different liquids on the egg.

Cell City

Essential Questions:
1: What are the components of the cell?
2: How are plant and animal cells different?
3: How do cells combine to form organisms?

This week we will continue to explore the cell organelles. Students will compare and contrast the plant, animal and bacterial cells. They will look at cheek cells and cells from Elodea leaf.

Students will create a city, in class, that will represent the living cell.

Amazing Finds

Do you want to know if the type of flavoring in bubble gum has an effect on how long the flavor lasts? Are you interested in finding out which kind of water:hot,cold or water at room temperature will freeze faster? Have you wondered how you can tell a hard boiled egg from a raw egg? If you are given different liquids which liquid will evaporate the fastest? Which brand of sponge has the most absorbency?Is root beer more acidic than vinegar?Do you want to know which popcorn pops the best or if Carnations can drink water?
To find out the answers for these questions don't go far away. The answers are just a click away. Students have followed the basic scientific method to find a solution to these problems.
