QUICK REVISION ON SCIENCE

Assalamualaikum & and a very good morning.

How are you all doing today?

I believe that towards end of the year,everybody in the schools are juggling with lots of activities but most important of all is the revision for year end exam.

As some of us ( teachers) may need to cope with this crucial time as we have to cater the needs of our students so as the smooth flow of activities arrangement, consider the way of revision activity in this entry as an alternative.

I believe that all of us are aware that our students these days love to be the centre of attention.

they love to be given responsibilities and chances to do things on their own.

So, this was what we had in our revision period last time.

As simple as this,

to revice the whole year topics,3-4 students were assigned in 1 group.

It actually depends on how many topics you plan to cover and the number of students you are having.

So,basically, each group was assigned with a topic.

They sat together,discussed, created a mind map and made sure that they became the specialist of that particular topic.

each group chose a representative to be their spokesperson.

representatives of all groups chose one station each and the whole class was in a huge circle.

the rest of the group members walked to a station to another,to actually get explanation of each topic available.

they walked around in a clockwise.

only representatives stayed at their station as the host.

after all groups have visited all stations,it was the hosts' turn to freely visit all stations.

as for conclusion,

my students seemed to enjoy this way of revising as they were given the 'power' to control the session :)

and of course it was a fruitful session when most of them could give me valuable feedbacks .

here are some pictures throughout the activity :)

enjoy doing revision :)

assalamualaikum and good afternoon

it has been weeks that i do not update anything in this blog

forgive me ya..it just  the crucial time of finishing all sorts of documents for PEKA assessments

by the way, we are currently focusing on quick revision as well as drilling on answering techniques for all my primary 6 students..in a hope that they'll master the techniques within this short period left.

i myself have assigned the students in my class to do revisions on primary 5 and 4 topics by groups' presentation.

let's have a look on their preparation :)

ECLIPSE OF THE MOON AND SUN : PRIMARY 6

An eclipse is an astronomical event that occurs when an astronomical object is temporarily obscured, either by passing into the shadow of another body or by having another body pass between it and the viewer. An eclipse is a type ofsyzygy.^[1]

The term eclipse is most often used to describe either a solar eclipse, when the Moon's shadow crosses the Earth's surface, or a lunar eclipse, when the Moon moves into the Earth's shadow.

ECLIPSE OF THE SUN

 ECLIPSE OF THE MOON

assalamualaikum and greetings to all..

today, me and my Primary 6 students did a lab activity on Eclipes.

as usual,they were divided into groups and they set up their own models to simulate the phenomenon of eclipses.

check out the pictures ya peops :))

UPSR Seminar By En. Mohd Johari M. Sahar

Bismillahirrahmanirrahim

A very good day everybody,

Today, from 2.30pm - 4.30 pm all UPSR candidates in SSS were so lucky to be given a chance to attend this Seminar.

It was held since Monday for different subjects and today it was Science subject's turn.

I was there with all my beloved students.

The speaker was a very experienced & well known Science teacher.. MR JO.

Hopefully,all my students managed to absorb as much useful infos & tips from the Seminar.

It was indeed a very LIVELY session and I was so proud that my students were so proactive.

Good job peops...KEEP IT UP :)

two thumbs up to MR JO for being an excellent speaker.

Let's browse on some pictures taken during he Seminar :)

Environmental Destruction : Standard 6

Environmental degradation is the deterioration of the environment through depletion of resources such as air, water and soil; the destruction of ecosystems and the extinction of wildlife. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable.

Environmental degradation is of many types. When natural habitats are destroyed or natural resources are depleted, environment is degraded.

Environmental Destruction

The planet's natural ecosystems and regenerating bio-capacity are being severely degraded and, as a result, this compromises the ability of the planet to sustain life. Forests, fisheries, oceans, rangeland, fresh water systems (lakes, wetlands, rivers) and other natural ecosystems are all threatened while many are on the verge of collapse. Water, land and air are getting increasingly polluted, water tables are falling, soil erosion is leading to desertification, global warming is well underway, and species are dying out 1000 times faster than their natural rate of extinction.

Facts

Forests
• We are losing forestland at a rate of 375 km2 each day. This is more than the total area of New Hampshire, Vermont, Massachusetts, Rhode Island, Connecticut, New Jersey and Delaware combined!
• The world has already lost 80% of its original forests.
• 1.1 billion acres of tropical forest were cleared in just thirty years, between 1960 and 1990.
• Brazil lost 91.4 million acres of its tropical forest between 1980 and 1990. This is almost the total area of North and South Dakota combined.
• At the world's current rates, 5-10% of tropical forest species will become extinct every decade.


Fisheries
• 75% of all the fish stocks in the world are already either: exploited, over-exploited or recovering. 27% of coral reefs have already been and 70% of Earth's coral reefs will cease to exist within the next forty years. The world has lost half of its coastal wetlands, including mangrove swamps and salt marshes.
• In the next 30 years, as many as one-fifth of all species alive today will become extinct. 23% of all mammals and 12% of all birds’ species were considered "threatened" in 2003.

assalamualaikum & good day :))

from the facts shared above..it's well said that this topic is all about what's our globe up to nowadays.
it's so unfortunate that we have to see things happening around us helplessly.
as a matter of a fact, WE CAN HELP BY AT LEAST STOP BEING SELFISH
realizing the important roles can be played by everyone in the society,there's a strong reason of including this topic in Science for Standard 6.
i decided to make my students come out with their own presentation which were great ones as the outcome.
enjoy the videos recorded throughout the whole session and hopefully will be giving all of you some clear ideas about the whole topic. 

GROUP 1 : EXCESSIVE LOGGING & ILLEGAL HUNTING

GROUP 2 : EXTINCTION OF SPECIES

GROUP 3 : GLOBAL WARMING

GROUP 4 : WATER POLLUTION

GROUP 5 : AIR POLLUTION

GROUP 6 : LANDSLIDE,SOIL EROSION,FLASH FLOOD

assalamualaikum all my readers.

today's topic of the entry is ELECTRICITY

subtopic is SERIES CIRCUIT & PARALLEL CIRCUIT

this lab activity was carried out on 25th April 2012.

the students are from my Primary 5 class.

 above : SERIES CIRCUIT

above : PARALLEL CIRCUIT

above : SERIES CIRCUIT (added with dynamo)

There are two basic ways in which to connect more than two 

circuit components: series and parallel.

Components of an electrical circuit or electronic circuit can be connected in many different ways. The two simplest of these are calledseries and parallel and occur very frequently. Components connected in series are connected along a single path, so the same current flows through all of the components. Components connected in parallel are connected so the same voltage is applied to each component.

A circuit composed solely of components connected in series is known as a series circuit; likewise, one connected completely in parallel is known as a parallel circuit.

In a series circuit, the current through each of the components is the same, and the voltage across the components is the sum of the voltages across each component.In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component.

SCIENCE STANDARD 5 : MiCrooRgAniSm

Assalamualaikum w.b.t & a very good evening,

The first topic in Primary 5 Science is MICRRORGANISM.

Followed are the pictures of two experiments conducted in my class in the beginning of year 2012.

Growth of microorganisms ( patches of fungi) on orange skin.

the oranges were left in the lab at room temperature for 4 days.

These are the pictures of the oranges taken on the 4th day of experiment.

observation : bigger size of fungi patches could be seen on the skin day by day

conclusion : microorganism grow

Another experiment was regarding 'microorganisms breathe'

4 beakers of same size of dough were added with 1/2 tablespoon of yeast,1 tablespoon of yeast,2 tablespoon & 3 tablespoon respectively.

observation : the more yeast added to the dough the higher it risen

conclusion : microorganisms breathe( produce air bubbles, the dough risen)
