The topic will cover Radioactive Substance,  Nuclear Energy and Handling the Radioactive Substances. What are radioactive substances are substances which have unstable nucleus. The nuclear emits energy to become stable.  There are 3 types of radiation Alpha, beta and gamma radiation

Alpha Radiation: Consist of Helium Nuclei, positively charge,move slowly, low penetrating power and high ionization
Beta Radiation: Consist of Electron, negative charge, move very fast, high penetration power and low ionization
Gamma Ray: Electromagnetic waves, Neutral charge, move speed of light, very high penetration power and low ionization

Production of Nuclear Energy

Nuclear Fission happens when neutron bombard the nucleus of uranium – 235. This is done through a nuclear reactor. The  nucleus absorbs neutron and become more unstable. Then it divides again. This process releases nuclear energy. Nuclear  Fusion happens when lighter atoms collided to form a bigger atom. The fusion of nuclei accompanied with tremendous amount of energy

example:
2 hydrogen collided to form Helium. This process always happens in the sun?

How do you define radioactive substance?
Iodide 131
Carbon 14
Cobalt 60
Uranium 235

3 types of radioactive
Alpha radiation ( It is the Helium particle)
Beta radiation  (Emission of  electron)
Gamma radiation (High Electromagnetic wave)

Penetration power
Gamma Ray has the highest penetration power. The lowest penetration power is the alpha radiation

Ionizing power
Alpha can ionize easier compared to beta particle and gamma ray
Popular questions for SPM Science
What is nuclear fission?
What is nuclear fusion?
Understand how the nuclear reactor works?
What are the effects of radiation emission?

Plants which go for vegetative reproduction are
strawberry, onions, sweet potato , ginger, banana

Advantages are:
Does not require any polen and partner to reproduce
Fast production- Good for farmers
New plants exactly the same as the parent plant
The new plants inherit the same characteristics from the parent plant

Disadvantages
New plants will grow very close to each other
Competition with parent plants Limited variety of plants

Vegetative structures are
Runners
Bulbs
Roots
Rhizome
Leaves

Very often students tend to skip important chapters or sub chapters. From our analysis, most of the students tend to skip the Endocrine System because they find it too difficult to digest. We have prepared some notes to guide students into understanding the Endocrine System.

Function of Endocrine System
a) Made up of glands
b) Secrete hormones
c) Types of gland … Pituitary gland, Thyroid gland, Adrenal gland, Pancreas, Testis, Ovary.

Thyroid gland
Producte thyroxine. Contorl metabolic rate

Adrenal Gland
Secretes Adrenaline to increase heartbeat, breathing, blood pressure and blood glucose

Pancreas
Produce Insulin to control glucose level

Testis
Produce testerone which control male sex organs and secondary sexual characteristics

Ovary
Produce Oestrogen and Progestrone which control female sex organ and secondary sexual characteristics

Pituitary Gland
The pituitary hormones help control some of the following body processes:

• Growth
• Blood pressure
• Some aspects of pregnancy and childbirth including stimulation of uterine contractions during childbirth
• Breast milk production
• Sex organ functions in both men and women
• Thyroid gland function
• The conversion of food into energy (metabolism)
• Water and osmolarity regulation in the body
• Secretes ADH (antidiuretic hormone) to control the absorption of water into the kidneys
• Temperature regulation

Just to share some tips for you guys. Science PMR

Some last minute look up at the website-  PMR Science. Just would like some of the students to memorize this diagram.  Students are required to understand the function for A,B,C and D. Study the function of each pin. How would be the question format?

The questions can be as simple as:

1. What is the function of the fuse?
2. Where is the Live wire for the 3 pin plug?
3. What is the function of the Earth wire?
4. What is the difference between the 2 pin plug and the 3 pin plug
5. What is the color of the Neutral Wire?
   

The diagram above  shows that :

1. A is the Earth
2. B is the Neutral
3. D is the Live
4. Fuse

The purpose of installing a fuse is to prevent over current. One of the safety feature for the device
