Activity
In this activity for
stage 4 students, students are required to write their own method to
investigate the effect of either light or water on photosynthesis and therefore
plant growth. Students are given an aim and are expected to come up with their
own hypothesis and method. They will need to consider thing such as:
replication, minimising uncontrolled variables and measuring their results. By
coming up with their own method, students can make their investigation as
simple or complex as they like, fitting to their ability level.
Syllabus Dot Points Covered
WS4 Students
question and predict by:
b.
making predictions based on scientific knowledge and their own observations
WS5.2 Students plan
first-hand investigations by:
a.
collaboratively and individually planning a range of investigation types,
including fieldwork, experiments, surveys and research
b.
outlining a logical procedure for undertaking a range of investigations to
collect valid firsthand data, including fair tests
c.
identifying in fair tests, variables to be controlled (held constant), measured
and changed
d.
describing safety and ethical guidelines to be addressed
WS5.3 Students
choose equipment or resources for an investigation by:
b.
selecting equipment to collect data with accuracy appropriate to the task
WS6 Students conduct
investigations by:
a.
collaboratively and individually conducting a range of investigation types,
including fieldwork and experiments, ensuring safety and ethical guidelines are
followed
b.
assembling and using appro
d.
following the planned procedure, including in fair tests, measuring and
controlling variables
e.
recording observations and measurements accurately, using appropriate units for
physical quantities
g.
assessing the method used and identifying improvements to the method
Activity Sheet
Students
are not given a specific sheet for this activity, however they can make use of
the summary sheet and website shown below. The aim "Investigate the effect
of light or water on photosynthesis" will be written on the board.
Students may use this link or this sheet to assist in their experimental design:
