On The Farm

This unit has the broad theme of food production.

I have collaborated on investigations into the process of photosynthesis and I can demonstrate my understanding of why plants are vital to sustaining life on Earth.
SCN 3-02a

Introduction

Where do trees come from? Where do plants get their mass from? This question was asked by Jan Baptist van Helmont.

Experiment 1 - Effect of changing temperature on the number of oxygen bubbles
  • Have light intensity (white light) and CO2 at a maximum
  • Change the temperature by clicking on the thermometer
  • Record your results in a table and draw a graph

Experiment 2 - Effect of the colour of light on the number of bubbles
  • Have temperature, light intensity and CO2 at a maximum
  • Change the the colour of light by clicking on the lamp switch
  • Record your results in a table and draw a bar chart


Experiment 3 - Effect of the amount of carbon dioxide on the number of bubbles
  • Have temperature and light intensity (white light) at a maximum
  • Change the the amount of CO2 by clicking on the bottle
  • Record your results in a table and draw a bar chart

Experiment 4 - Effect of the light intensity on the number of bubbles
  • Have temperature and CO2 at a maximum. Use white light.
  • Change the the light intensity using the dimmer switch above the bulb
  • Record your results in a table and draw a line graph

Using a microscope, I have developed my understanding of the structure and variety of cells and of their functions.
