Tupoints class 8 lessons and practice modules are designed to build a lasting learning and practicefoundation not only for class 8 but also for higher classes which need a different approach in terms of learning and practice so as to be able to cope up with higher learning and practice levels. Despite this, the lessons are not learning heavy and encourage students to learn and practice well and work on remediation of their doubts themselves using Tupoints learning gaps analysis and revision materials.

,Science Course Structure Class VIII
1. Food (Periods – 22)
Crop production
Key Concepts:- Crop production: Soil preparation, selection of seeds, sowing, applyingfertilizers, irrigation, weeding, harvesting and storage; nitrogen fixation, nitrogencycle.
Micro-organisms
Key Concepts:- Micro organisms – useful and harmful.
2. Materials (Periods – 26)
Materials in daily life
Key Concepts :- Synthetic clothing materials. Other synthetic materials, especiallyplastics; usefulness of plastics and problems associated with their excessive use.There are a variety of fibrous materials in use. A material is chosen based on desiredproperty.
Different kinds of materials and their reactions.
Key Concepts Metals and non-metals.
How things change/ react with one another
Key Concepts:- Combustion, flame All fuels release heat on burning. Fuels differin efficiency, cost etc. Natural resources are limited. Burning of fuels leads toharmful by products.
3. The World of the Living (Periods – 44)
Why conserve
Key Concepts:- Conservation of biodiversity/wild life/ plants; zoos, sanctuaries,forest reserves etc. flora, fauna endangered species, red data book; endemic species,migration.
The cell
Key Concepts:- Cell structure, plant and animal cells, use of stain to observe,cell organelles – nucleus, vacuole, chloroplast, cell membrane, cell wall.
How babies are formed
Key Concepts:- Sexual reproduction and endocrine system in animals, secondary sexualcharacters, reproductive health; internal and external fertilization.
4. Moving Things, People and Ideas
Idea of force
Key Concepts:- Idea of force-push or pull; change in speed, direction of movingobjects and shape of objects by applying force; contact and non-contact forces.
Friction
Key Concepts:- Friction – factors affecting friction, sliding and rolling friction,moving; advantages and disadvantages of friction for the movement of automobiles,airplanes and boats/ships; increasing and reducing friction.
Pressure
Key Concepts:- Idea of pressure; pressure exerted by air/liquid; atmospheric pressure.
Sound
Key Concepts:- Various types of sound; sources of sound; vibration as a cause ofsound; frequency; medium for propagation of sound; idea of noise as unpleasant andunwanted sound and need to minimize noise.
5. How Things Work (Periods – 14)
Electric current and circuits
Key Concepts:- Water conducts electricity depending on presence/ absence of saltin it. Other liquids may or may not conduct electricity. Chemical effects of current.Basic idea of electroplating.
