Designing and Building Compound Microscopes and Telescopes Using Convex Lenses

Activity 6.13 ISS ICS

Aim: To design and build a compound microscope and a telescope using convex lenses

Instructions:
1. Work in groups.
2. Gather information on compound microscope and Video on the working
telescope from reading resources or websites based on principle of microscope
the following:
(a) Type of lens used and its function
(b) Criteria for choosing objective lens and eyepiece lens
of a compound microscope which can produce the
largest image http://bt.sasbadi.com/p4265a
(c) Criteria for choosing objective lens and eyepiece lens
of a telescope which can produce the clearest and Video on the working
brightest image principle of telescope
(d) Draw ray diagrams to show the formation of images
in compound microscope and telescope
3. Discuss the information and complete the K-W-L Chart as
a guide to design and build your compound microscope
and telescope. You can download and print the form http://bt.sasbadi.com/p4265b
from the website given.
4. Sketch the design of your compound microscope and Download K-W-L Chart
telescope.
5. Build your compound microscope and telescope based
on your sketch.
6. Comment on the effectiveness of the design and improve http://bt.sasbadi.com/p4265c
on the design produced.
7. Present your group’s design, and the compound
microscope and telescope built.
