1ST TERM
UNIT 0: KNOWTHE IMPORTANCEOFSCIENCE
ACTIVITY 1: Scientific Method In Action
The
Strange Case of BeriBeri
In
1887 a strange nerve disease attacked the people in the Dutch East Indies. The
disease was beriberi. Symptoms of the disease included weakness and loss of appetite,
victims often died of heart failure. Scientists thought the disease might be caused
by bacteria. They injected chickens with bacteria from the blood of patients with
beriberi. The injected chickens became sick. However, so did a group of chickens
that were not injected with bacteria. One
of the scientists, Dr. Eijkman, noticed something. Before the experiment, all
the chickens had eaten whole-grain rice, but during the experiment, the chickens
were fed polished rice. Dr. Eijkman researched this interesting case and found
that polished rice lacked thiamine, a vitamin necessary for good health.
1.
State the Problem
2.
What was the hypothesis?
3.
How was the hypothesis tested?
4.
Should the hypothesis be supported or rejected based on the experiment?
5.
What should be the new hypothesis and how would you test it?
How
Penicillin Was Discovered
In
1928, Sir Alexander Fleming was studying Staphylococcus bacteria growing in culture
dishes. He noticed that a mold called Penicillium was also growing in some of
the dishes. A clear area existed around the mold because all the bacteria that
had grown in this area had died. In the culture dishes without the mold, no clear
areas were present. Fleming
hypothesized that the mold must be producing a
chemical that killed the bacteria.
He decided to isolate this substance and test it
to see if it would kill bacteria.
Fleming transferred the mold to a nutrient broth
solution. This solution contained
all the materials the mold needed to grow. After
the mold grew, he removed it
from the nutrient broth. Fleming then added the
nutrient broth in which the mold
had grown to a culture of bacteria. He observed
that the bacteria died which was later used to develop antibiotics used
to treat a variety of diseases.
6.
Identify the problem.
7.
What was Fleming's hypothesis?
8.
How was the hypothesis tested?
9.
Should the hypothesis be supported or rejected based on the experiment?
10.
This experiment leads to the development of what major medical advancement?
ACTIVITY 2: Scientific Method - Group Project
Instructions: Give each group or pair one of the scenarios below.
Ask the group to design and experiment to answer the experimental
question. Students should identify a control group, dependent and
independent variables and possible outcomes or what type of data would
be gathered. Stress to students that they will not actually be
performing these experiments. Have students either turn in their design
on paper or do a mini-presentation to the class.
Does the wavelength of light (R.O.Y.G.B.I.V.) affect a plant’s growth?
Does Rogaine really improve hair growth?
Is acid rain causing a decline of frog populations?
Does the hormone estrogen increase the milk yield of dairy cows?
es the size of a fish tank determine how large a fish will grow?
Does aspirin keep cut roses fresher longer?
Will crickets chirp more if the temperature is warmer?
Do wounds heal faster when they are covered by Band-Aids?
Which battery lasts longer, energizer or duracell?
Does hot water freeze faster than cold water?
Do tanning beds cause skin cancer?
What causes leaves to fall in autumn (light, temperature, or both)?
ACTIVITY 3:In these exercisesI proposefamiliar withsome formalsynonyms forcommon words andconstructionsin scientific articles.
WORK TO PRESENT IN CLASS:This term you willhave todo a work in groups of twoor three people, send it to the teacherandexpose in class.Can not exceed 8 pages and must bein English.You canchoose between:
- finda scientific article andmake a commenttext(summary, backgrounds, personal opinion...)
- selecta scientist whoknow indicating toeachtheir contributionsto scienceand societyof his time
UNIT 2: PLANETEARTH ACTIVITY 1:After watching the video, you have to send by email abrief summary. Discusssome ideasthat havecaught yourattentionand why.You can do thisindividually or in pairs.Twopagesmaximum.
You have to answer the following questions.You can do itindividually or in pairs and send by email to the teacher. 1) Whatconceptsgeocentrismandheliocentrismmean? 2)Indicatessome
ofGalileo's contributions to
astronomy. 3) State Kepler's lawsandfind a picturefor
each ofthem.
4)
The figure shows the elliptical orbit of a planet with the Sun at the
focus. The areas of regions 1 and 2 are the same. If the planet takes times t1
to go from one end to the other end of region 1 and t2 to go from one end to
the other end of region 2, then what is the relationship between t1 and t2?
5)State thelawof universal gravitation, writeits formulaand indicatethe meaningof each ofits terms. 6)Calculatethe force with whichthe Earth andthe Moonare attracted,knowing themass of the Earthis5.98.1024kg, the mass of the Moon7,2. 1022kgandthedistance between themis3.84. 105Km. 7) Is constantthe value ofg? Calculate the surface gravityof Marsknowing thatits massis 6,5. 1023kgand itsradius is3,38. 106 m. 8) Explain the big bang theory briefly.
