  1. Want an “A” Here’s the place to start. DefinitionsA Click for each heading then for the answer

  2. Alloy 3 is a mixture of metals e.g. bronze is a mixture of copper and tin.

  3. Alloys =4 to know • Bronze = • Copper and Tin • Brass = • Copper and Zinc • Solder = • Lead and Tin • Steel = • Iron and Carbon

  4. Acid • has pH less than 7 • turns blue litmus paper RED • sour taste

  5. Area W = length X width cm2 L

  6. Atom smallest part of an element that has the properties of the element.

  7. Atomic Number The number of protons in an atom (of an element)

  8. A.C. Alternating Current Electricity that changes direction 50 times a second (50 Hz)

  9. Aerobic Respiration Using oxygen to release energy from food in all cells

  10. Acceleration = change in velocity time taken Units = m/s2

  11. Anther makes pollen in a flower (male part)

  12. Antagonistic Muscles pairs of muscles that pull a bone in opposite directions e.g. biceps and triceps

  13. Asexual Reproduction Reproduction using just one parent producing identical offspring (young) e.g. cuttings or runners in plants

  14. Atmospheric Pressure • The weight of the atmosphere (air) pressing down on earth. • Gets smaller as you climb higher • Measured by BAROMETER

  15. A.C. • Aerobic Respiration • Acceleration • Anther • Antagonistic Muscles • Asexual Reproduction • Atmospheric Pressure • Do I know it?? • Alloy • 4 examples of alloys • Acid • Area • Atom • Atomic Number
