26. Super science diagrams
Learning objective: How can we show another scientist what equipment we have used and how to set it up?

27. Diagrams = You need a sharp pencil, ruler and a pen.
Diagrams should be 2D and drawn with a pencil and a ruler and not shaded.
You should always fully label a diagram.
The names of the equipment should be written in pen. =
Go over the points, may need to be explained in simpler English i.e. 2D = flat.
Round bottom flask
Liquid

28. What is this? Look at the diagrams.
Can you match it with the equipment? 1. 3. 5.
Hands up, Q+A session. 2. 4.

29. Measuring volumes of liquids.
Learning objective: How can we measure the volume of liquids?
Can you measure liquids precisely?

30. Anagrams bbuunnneerrs iodprt zeaug eeabrk tteeutbs aattufmsy gggoels
Extension activity.

31. Which pieces of equipment could we use to measure liquids?

32. How can we measure volume?
Units = cm3

33. Reading volumes
You get a more accurate reading if you bend down so that your eye is level with the liquid in the measuring cylinder.

34. Precise reading
If you look carefully at the liquid in a tube, it seems to go up at the sides of the tube. The curved shape it makes is called the meniscus. You should take your reading from the bottom of the meniscus.

35. What is the volume? Fill the container with the different liquids.
Tip them into the measuring cylinder.
Read off the volume that the container holds.
Record your results in your
booklet.

36. Measuring Temperature.
Learning objective: How we measure temperature?

37. How can we measure temperature?

38. Thermometer safety rules
Never put a thermometer down where someone can knock it off the bench.
Make sure your thermometer has a safety ring fitted.
If you break a thermometer, ALWAYS tell your teacher. Do not try to clear it up yourself.

39. Magnesium and acid Measure 10cm3 of acid into the test tube.
Take the temperature, write down your result.
Add your magnesium strip.
Take the temperature every 30 seconds.
10cm3 of acid
magnesium

40. Have a go!
Can you read the thermometers on your worksheet?

41. Measuring Time! Learning Objective: How can we measure time?
What are some different units of time?

42. What are the units of time?
Milliseconds
Degrees
Days
Centimetres
Minutes
Grams
Years
Kilograms
Newtons
Hours
Meters
Seconds

43. How can we measure time?
Units = seconds

44. How do you use a stopwatch?
You need to know how to start, stop and re-set.

45. How long does it take you to move 20m?

46. How long does you shape take to fall to the bottom of the measuring cylinder?
Water
Paste

47. Hazard Splat!

48. Measuring mass. Learning objectives: How can we measure mass?
Can you read some different masses and use the correct units?

49. How can we measure mass?
Units = kg

50. How do we use measure mass in science?

51. What is the mass? Which piece of equipment has the highest mass?
Which piece of equipment has the lowest mass?

52. Can mass change in chemical reactions?
Measure 20cm3 of acid into the conical flask and put it on the balance. What is the mass?
Add a spatula of chalk. What do you observe?
What happens to the mass?
Spatula of chalk
Conical flask
20cm3 acid

53. What the mass? Mass Name:……………………………………………………………………….
1) Look at the readings below and note their masses.
