Linking Words: Sequence and Frequency
In Language class, our teacher, Pat Chujman asked that we create posters with linking words. I worked on them with Delfi, Tomi and Juani. Now, we are supposed to create sentences to fill in with frequency and sequence linking words for our peers to complete:
1. ____________ we have 3 meals _______.
2. I _________ go to the gym, but only if I have free time.
3. Get your homework done __________ you get home.
4. ________, I think that recycling should be incorporated in all schools for the reasons above mentioned.
5. ________ that terrifying moment, I knew that I would _________ come back.
6. ______ I had realized that she _________ understood my issue.
7. Let’s eat and go to a movie ___________.
These are our posters:

Mechanical Reaper
We’ve been studying the Industrial Revolution in History class this past trimester. Each student picked an invention to present in class and I chose McCormick’s mechanical reaper. Here’s my visual aid presentation:
Endocrine System
The new topic in Biology is the Endocrine System and we were to do the activities on Male’s blog:
- Hormone: chemical substance produced by a gland, carried by the blood, which alters the activity of one or more specific target organs.
- Search in the internet a picture which shows the glands which secrete hormones in the human body.
What hormones secrete each gland:
Adrenal gland: Adrenaline
Pancreas: Insuline
Testis: Testosterone
Ovary: Oestrogen
Thymus: Thymosin
Thyroid gland: Thyroxine and calcitonin
Pituitary gland: Growth hormone
Pineal gland: Melatonin
3. ADRENALINE. State the effects of adrenaline. Chose a picture which shows a situation in which adrenaline is secreted. Explain.
Adrenaline is when you are frightened, excited or keyed up. There your brain sends impulses along a nerve to your adrenal glands, and these secrete adrenaline into the blood. The main effects of adrenaline are: Your hearts beats faster, your breathing rate increases, your pain body’s ability decreases and it causes a noticeable increase in strength and performance.
“The Border Builder” by Carol Rumens
In Literature with Luz, Jose and Delfi, we worked on “The Border Builder” by Carol Rumens and wrote up a questionnaire for our peers to answer later on. Here’s ours:
1. What does the writer think ahout borders?
2. Explain the ending of the poem.
3. Who is the persona talking to?
4. Explain what effect repetition has on the reader.
5. Explain the following quotation: “My bricks, O my genuine bricks Made of my genuine blood!”
6. How can you relate the poem to the present day?
Extracting DNA
Today we went to the lab and did an experiment on extracting DNA. This is how it got carried out:
Aim:
To extract DNA from natural products
to observe the fibrilar structure of DNA.
Materials
Plastic cups – onion, banana
test tubes – Distilled water
knife – detergent
sticks – salt
a beater – ethanol
Method
1- Cut the central part of the onion into cubes.
2- Add 3 tsp of detergent and 1 of salt in a plastic cup, and pour distilled water up to the top.
3- Mix this solution with the pieces of onion.
4- Beat all the mixture at high speed for 30 seconds.
5- Filtrate the liquid with a coffee filter.
6- Fill ¼ of a test tube with the filtrate.
7- Add some pieces of banana and mix thoroughly.
8- Add the same volume of ethanol, carefully, so that it flows through the walls of the test tube and forms a layer on the filtrate.
9- Let it rest for 2-3 minutes until a cloudy area is formed between the 2 layers.
10- Extract a network of white fibres of DNA and place it on a Petri dish.
11- Add few drops of blue methylene and record your observations.
Results
Record your observations!
Discussion
a- Where in the cell is the DNA?
The DNA is in the nucleus.
b- What are the fibres made of?
The fibres are nucleotides joined together.
c- What is a gene?
A gene is a length of DNA that codes for a protein.
Conclusion
What is the DNA?
DNA is deoxyribose neuceic acid.
