Objectives of the workshop
Parents will be able to pick up
• strategies to support your child’s learning
of Science
• understand the transition from Lower to
Upper Block
• techniques to manage Science
assessments
Science in GDPS :
Inquiry-based Approach
Learning science as Inquiry must go beyond merely
presenting facts.
Pupils are actively engaged
• collecting and using evidence collected from “outdoor
classrooms” and through hands-on experiments
• formulating and communicating explanations based on
scientific knowledge
Science Curriculum Framework
The science curriculum seeksto nurture the student as aninquirer. The end goal is forstudents to enjoy scienceand value science as animportant tool in helpingthem explore their naturaland physical world.
The Primary Science Syllabus aims to…
Provide primary pupils with
• basic scientific terms and concepts
• opportunities to develop skills, habits of mindand attitudes necessary for scientific inquiry
• prepare pupils towards using scientificknowledge and methods in making personaldecisions
• help pupils appreciate how science influencespeople and the environment

Exploring Science together
• Watching of Science documentaries (E.g.National Geographic Wild, DiscoveryChannel) and reading of Sciencejournals/magazines
• Go to nature parks
• Observing and explaining materials andtheir uses eg cooking wares

Techniques for Answering
Science questions
Answering MCQs
• Identify topic tested
• Link questions to the related concepts (orscientific ideas)
• Highlight/Underline/Circle key words
• Use “Elimination” method to choose the bestanswer
6 steps for answering OEQs
Step 1: Annotate the important information
Step 2: Identify topic that is tested
Step 3: Identify key concepts from the topic tested
Step 4: Identify Task/Command Words
Step 5: Note the marks
Step 6: Phrase the answers using the
templates/framework taught, where applicable
Task/Command Words
Command Words ExpectationsCompare Look for differences and come to a
conclusion [use comparative terms]
Describe State in words the main points
Classify Group based on common characteristics
Explain Interpret the information given, state the“how” and “why” of the results and possiblecauses [use COCA]
Identify Select/name the object, concept or process
State Give a short answer with no supportingreason required
Infer Draw a conclusion based on observations ofresults
Annotation Technique
• Effective reading strategy
• Helps in comprehending the question
• “Mark out” sections of question, with ahighlighter or by underlining
• Makes notes to ensure understanding
Animals give off
CO2 so CO2 increase
Plants take in CO2 during
photosynthesis so CO2 decrease
No change
in
composition
of gases
(2)
Identifying the Topic & Concept(s)
• After reading the question, try to identify the topicand concept based on previous questions attempted or experiments conducted.
Topic:Magnets, Forces & Energy
Concept:Interactions between gravitational and magnetic force
Topic:Energy
Concept:Use a lighter toy so the same amount of elastic spring force can push the toy to a greater height.
Topic:Water
Concept:Water gains heat to evaporate
Topic:Water
Concept:Rate of evaporation
Topic:Materials (properties) & electrical system
Concept:Rubber – flexible so the car will not be damaged Z – electrical conductor
Open-ended questions pertaining

• Investigation
(a) Aim
(b) Fair test
(c) Forming Conclusions
(d) Control setup
(e) Planning investigations
• Identifying relationships
(a) Aim
1) To find out if the variable changed affects theexperimental results
2) To find out how the variable changed affects theexperimental results
3) To find out the property of the materials [comparison tobe made]
ERVC
VC
ER
(a) Fair Test
Why/Why not
• There is only 1 variable changed(VC) in the experiment [state theVC changed in that question]
• There are more than 1 variablechanged in the experiment [… &…]
How
• Identify the aim
• Study how the given object/condition affects the experimental results
(c) Forming Conclusions
A conclusion is a statement which summarises the results of an experiment.
It basically answers the aim of the experiment using the experimental results
Water at room temperature
Water will gain heat
Observation of
results:
Water in D registers
a higher temperature
– faster/more heat
gain
(d) Control Setup
The control setup shows that it is the variable change that causes the difference in the
experimental results.
(e) Planning Investigation
Ensure fair test by changing only 1 variable

Recommended Materials for Revision
• Textbook• Workbook
• GDPS Topical Reviews & Notes• GDPS Practice Papers
Refer to the link below for MOE 2014 Science syllabus • https://www.moe.gov.sg/education/syllabuses/sciences
Tip:
Refer to MOE syllabus when doing revision
with your child. Don’t rely on reference
books as syllabus guide.
Tip:
If you desire extra practice for your child,
use other schools’ papers instead of
assessment books. However, don’t rely
on the answer key when marking your
child’ work.
The Ebbinghaus Forgetting Curve
• theory about how our memory works,proposed in 1885 by a Germanpsychologist named Hermann Ebbinghaus
https://www.youtube.com/watch?v=SCsQHe-NpaM
The Ebbinghaus Forgetting Curve
• The averaged results across multipleexperiments looked something like this
https://www.youtube.com/watch?v=GVXDcFKz7DA
The Ebbinghaus Forgetting Curve
The Ebbinghaus Forgetting Curve
• Need to spend time actually understanding thematerial before child can start memorizing it
- pay attention in class
- encourage child to clarify doubts with teachers
- put effort into understanding their homework
assignments
The Ebbinghaus Forgetting Curve
The graph reveals another fact: Cramming doesn’t work!
• the forgetting curve is at its steepest early on
- everything you cram in the day before the test will slip
out of your head like sand through your fingers
• You might be able to retain 70-80% of what you’vecrammed by the time you take the test
• Chances are, if he is cramming, he probably didn’tbother to spend time understanding and digestingeverything beforehand.
BEAT The Ebbinghaus Forgetting Curve!
• Spaced Repetition
• Revise and relook at what we have taught within aday of gaining new knowledge
• Note down the days that Science lessons areconducted and have a quick 15mins walk- throughof topic at end of the day with your child

“How to Study Better – Best Study Techniques” by Ron White
Other Strategies for Recall
• Mindmaps / concept maps
• Teach someone else
• Do it with music
• Acrostics / Mnemonics
• Chunking
• Take notes
Example of Acrostics
• Factors affecting rate of evaporation:
Wind
Exposed surface area
Temperature of surrounding
• Magnetic materials
Steel
Iron
Nickel
Cobalt
Chunking
• The water from the __________ gained heat and evaporated.
• The warm water vapour touched the cooler __________ surface,
• Lost heat and condensed to form water droplets
Getting ready for PSLE
• Organising materials (Gathering allrelevant books, files, notes, practice papersin one place)
• Planning a study schedule
• Having a conducive study environment
Exceling in Science requires time, effort and daily interactions. Applyingstrategies has proven effective in helping pupils analyze questions,interpret data and apply the concepts they have learnt.
