Science Practicals and Inquiry Skills
This chapter page turns the high-level subject view into an ordered learning slice, with direct links from curriculum items into topic and skill detail.
Ordered curriculum items
Each curriculum item can now route into topic and skill-level detail.
2
Find experiment variables
Separate what is changed, measured and kept constant.
3
Make clear observation tables
Organise qualitative and quantitative data from practical work.
4
Conclusion from evidence
Use observations and data to support or reject a prediction.
5
Improve the experiment
Recognise limitations and suggest better controls or measurements.
6
Test pH with indicators
Use pH paper or universal indicator and classify samples.
7
Test acid-base properties
Observe reactions of HCl and NaOH with indicators, zinc and sodium carbonate.
8
Classify lab reactions
Use observations from quicklime, ferrous sulphate, displacement and double displacement reactions.
9
Reactivity from lab results
Use displacement observations with Zn, Fe, Cu and Al salt solutions.
10
Test acetic acid
Observe odour, solubility, litmus effect and reaction with sodium hydrogen carbonate.
11
Soap in hard and soft water
Observe lather formation and cleaning effectiveness.
12
Observe stomata
Prepare a temporary mount and identify stomata under microscope.
13
Respiration releases carbon dioxide
Use experimental setup to detect carbon dioxide from respiration.
14
Observe asexual reproduction
Recognise binary fission in Amoeba and budding in yeast or Hydra.
15
Seed embryo parts
Locate plumule, radicle and cotyledons in a dicot seed.
16
V-I graph practical
Measure current and voltage, plot graph and calculate resistance.
17
Equivalent resistance practical
Measure or compute total resistance for two resistors in series and parallel.
18
Concave mirror focal length
Obtain image of a distant object and measure focal length.
19
Convex lens focal length
Obtain image of a distant object and measure focal length.
20
Glass slab ray tracing
Measure incidence, refraction and emergence angles and interpret lateral displacement.
21
Prism ray tracing
Trace incident and emergent rays through prism and observe deviation.

Chapter routes make the curriculum map feel sequential instead of abstract.
This is where parents, teachers, and schools can see what sits inside a chapter before jumping to practice or deeper topic and skill pages.
