In the following table, the values
for the displacement s of a moving car in the corresponding
elapsed time t, relative to an observer on the same
road, are given.

Table 2: Data for a displacement-time
graph for uniform velocity
- Use a spreadsheet to plot
a graph representing the displacement time relationship.
You should:
- Label the graph and legends
- Plot displacement on the
Y-axis
- Plot elapsed time along the
X-axis
- Develop a task for your class in
which the graph drawn can be used with the learners.
- Once you have created a task share this document online with your group (using the subject heading "Science Task "). Explain how you think the ICT tools could be useful in your classroom. Your tutor will stimulate an online discussion amongst your peers based on these responses.
This example
of the use of spreadsheets to explore cause and effect
in science may be useful.
Remember that the power of
the spreadsheets is that they store relationships.
You can design a template for plotting displacement,
time, velocity and acceleration graphs. Whatever values
you enter for displacement and time, velocity and
acceleration will be automatically calculated and
the graphs plotted for you. Try and design for constant
re-use from the outset. Explore other topics in science
that could use Excel for relationships and graphs.
