QCA

Objectives

Section 1: What are living organisms made from?
Children should learn:
  • that plants and animals contain organs
  • that tissues make up organs
  • to draw inferences from data

View related activities and outcomes

Section 2: a. How can using a microscope give us information about structure?
Children should learn:
  • to use a microscope safely and effectively
  • to prepare simple specimens on a slide for observation using a microscope
  • to make observations using a microscope and to record these as drawings

View related activities and outcomes

Section 3: b. How can using a microscope give us information about structure?
Children should learn:
  • to use skimming, scanning, highlighting and note taking as appropriate to different texts
  • how ideas about the structure of living things have changed
  • that plants and animals are made up of cells
  • that plant and animal cells are similar in a number of respects, but have significant differences
  • to make observations using a microscope

Section 4: What are cells like?
Children should learn:
  • that plant and animal cells are similar in a number of respects
  • that plant and animal cells have a cell surface membrane which keeps the cell together and controls what enters and leaves
  • that cells have cytoplasm which occupies most of the cell
  • that cells have nuclei which control activities of the cell
  • that there are significant differences between plant and animal cells

Section 5: Checking progress
Children should learn:
  • to relate ideas about cells and cell structure

View related activities and outcomes

Section 6: a. What do cells do?
Children should learn:
  • that there are different types of cell, adapted for different functions
  • to use secondary sources of information

View related activities and outcomes

Section 7: b. What do cells do?
Children should learn:
  • that cells form tissues, and tissues form organs
  • to name some important tissues in plants and humans
  • to explain the organisation of tissues, using a model

View related activities and outcomes

Section 8: a. How are new cells made?
Children should learn:
  • that cells can make new cells by dividing
  • that growth occurs when new cells are made and increase in size
  • that cell division begins with division of the nucleus

View related activities and outcomes

Section 9: b. How are new cells made?
Children should learn:
  • that cells have nuclei containing the information that is transferred from one generation to the next
  • that in plants, pollen and ovule are specialised cells which enable information to be transferred from one generation to the next
  • that at fertilisation, nuclei from pollen and ovule fuse to make a new and unique individual

Section 10: What causes pollen tubes to grow?
Children should learn:
  • how to frame a question that can be investigated
  • about the importance of sample size and the number of observations in biological investigations
  • to identify trends shown in graphs
  • to evaluate the strength of the evidence

View related activities and outcomes

Section 11: Reviewing work
Children should learn:
  • about types of cells, their functions and organisation into tissues and organs
  • to relate ideas about cell division to growth
