Objectives

You have some scientific investigations to review and you need to gather all the data you can to give the Greatly Green Growers next session. It’s time to draw graphs, make drawings and write reports. Can you explain your findings?

Science Objectives
i) Identify and describe the functions of different parts of flowering plants: roots, stem/trunk, leaves and flowers.
ii) Explore the requirements of plants for life and growth (air, light, water, nutrients from soil, and room to grow) and how they vary from plant to plant.

Working Scientifically

  1. Report on findings from enquiries, including oral and written explanations, displays or presentations of results and conclusions.
  2. Use results to draw simple conclusions, make predictions for new values, suggest improvements and raise further questions.
  3. Use straightforward scientific evidence to answer questions or to support their findings.

Other Curriculum Areas
Maths - Statistics

  • Interpret and present data using bar charts, pictograms and tables (Yr3).
  • Interpret and present discrete and continuous data using appropriate graphical methods, including bar charts and time graphs (Yr4).

You Will Need

Provided Resources

Lesson Planning

Teaching

  • Review the results of our investigations and begin to draw conclusions.
  • Use scientific knowledge to explain findings.

Activities

  1. Review and discuss the data from the data loggers, make comparisons and explain patterns (Yrs 3&4).
  2. Look at the results of the food dye experiment and draw conclusions on how water is transported in plants (Yrs 3&4).
  3. Either draw line graphs (Yr4) or write reports on findings (Yr3) and seek to explain and interpret results (Yrs 3&4).

Investigation - fair testing/problem solving/exploring over time
Look at the data from the data loggers and food dye investigation. What does this mean for the Greatly Green Growers? Review data, draw graphs, discuss and interpret findings.
Year 3 - Provide support and prompts to complete tasks.
Year 4 - Encourage a greater degree of independence.

Vocabulary
Data logger, data, table, line graph, bar graph, light levels, lux, temperature, transported, results
