Grade 7    

We're sure you and skoool will enjoy learning Natural Sciences!

Natural Sciences is about what things are made of, how they react with each other and how they change when they come together. React with skoool and revise the way you study Natural Sciences.

1. Cell Structure and Function Learn the names and functions of some of the structures found in plant and animal cells.

2. Plant Cells Learn the names and functions of structures found in plant cells.

3. Specialised Plant and Animal Cells Understand how different cells are adapted for their functions.

4. Respiration Learn that aerobic respiration is a chemical reaction that occurs in cells to release energy from glucose. Learn the word equation that represents it.

5. Defence Against Disease Understand how microbes can enter the body and how the body tries to prevent this from happening.

6. Micro-organisms Learn the different types of microbes that can cause disease.

7. White Blood Cells Learn how the white blood cells defend the body against disease.

8. Vaccines Learn that immunisations and medicines can be used to help the body fight infections.

9. Photosynthesis Learn that plants make food by photosynthesis and the word equation that represents it.

10. The Role of the Leaf in Photosynthesis Learn that the leaf is the organ where photosynthesis occurs and understand how it is adapted for its function.

11. Testing a Leaf for Starch Learn how to test a leaf for starch.

12. The Uses of Glucose Learn that the glucose made during photosynthesis can be respired or changed into a variety of chemicals by combining with other elements.

13. Difference Between Photosynthesis and Respiration Learn the difference between photosynthesis and respiration.

14. Properties of Solids, Liquids and Gases Learn the properties of the three states of matter.

15. The Particle Theory Learn how to use the Particle Theory to explain the properties of solids, liquids and gases.

16. Change of State - Water Understand what happens when a substance changes state.

17. Melting and Boiling Point Understand what happens, in terms of energy and particle movement, when a substance changes state.

18. Metals Learn that elements vary widely in their physical properties and understand how the properties of elements can be used to classify them as metals.

19. Non-metals Learn that elements vary widely in their physical properties and understand how the properties of elements can be used to classify them as non-metals.

20. Acids, Alkalis and Indicators Learn how to use indicators to classify solutions as acidic, alkaline or neutral.

21. Acid Base Reactions Understand how different bases react with acids and write word equations for the reactions. Learn how to test for carbon dioxide gas.

22. Everyday Neutralisation Reactions Learn about everyday neutralisation reactions.

23. pH Scale Learn that pH is a measure of the strength of an acid or alkali and how to interpret the colours of universal indicator solution.

24. Magnetic Fields Understand that a magnetic field is a region of space where magnetic materials experience forces and learn that magnetic field line patterns show the relative strength of magnetic fields.

25. Understanding Magnets Learn that magnets attract magnetic materials and that like poles repel and unlike poles attract.

26. Magnetism and Electric Current Learn that wires carrying an electric current produce a magnetic field and that a current in a coil produces a magnetic field pattern similar to a bar magnet.

27. Plotting a Magnetic Field Learn how to plot the magnetic field around a bar magnet using a plotting compass.

28. Forces Learn what forces are and what they can do.

29. Mass, Weight and Gravity Learn that the weight of an object on Earth is the result of the gravitational attraction between its mass and that of the Earth, and know that weight is a force so is measured in newtons.

30. Unbalanced Forces Learn that unbalanced forces change the speed or direction of movement of objects and that balanced forces produce no change in the movement of an object.

31. Balanced Forces Learn that balanced forces produce no change in the movement of an object.

32. Stretching Materials Learn that extension is proportional to load, within the elastic limit of a material.

33. Friction Find out how frictional forces, including air resistance, can affect the motion of an object.

34. Useful Friction Learn how frictional forces can be useful.

35. Stopping Distances Find out how to calculate the total stopping distance of a car.

36. Factors Affecting Braking Distance Understand that the braking distance of a car depends on its speed and other factors which affect the frictional forces needed to stop the car.

37. Factors Affecting Thinking Distance Understand that the stopping distance of a car depends on the alertness of the driver as well as its speed and frictional forces.

38. What Forces Do Learn what forces can do and how to measure them.

39. Gravity Learn that gravity is a force of attraction which acts on Earth towards the centre of the planet, and that the size of the force of gravity depends on the mass of each object and the distance between them.

40. Gravity and the Solar System Understand how the movement of planets around the Sun is related to gravitational forces.

41. Satellites Learn that the Moon is a natural satellite of the Earth and how satellites stay in orbit around the Earth.

42. Uses of Satellites Learn some uses of artificial satellites.
