Here are a few of the many lesson ideas that are included in the School Technology
Resources Teacher Resource CD for SCALAR products.
- Use the handheld microscope to examine materials which have poor and good
water absorbency, and formulate and test a hypothesis which predicts absorbency
based on handheld microscope close-ups of a material.
Allow a piece of fruit to decay, and observe the growth and structure of the
Go on a seed hunt and collect as many different seeds as you can find, as
well as a leaf or flower from the same plants. Study the seeds to try to determine
how they travel (carried by wind, by getting attached to animals or insects,
floating on water, etc.).
- Create a bulletin board matching capture images of the seeds with 1X images
of the plants that they came from.
- Study spiders to determine whether they are "wanderers" or "web-spinners".
Wandering spiders have 2 claws on each foot and very good eyesight. Web-spinners
have poor eyesight but are very sensitive to vibrations, and have three claws
on each foot.
Obtain a collection of live spiders,
each in separate jars, and ask students to devise a way to test which spiders
have good eyesight and which are more sensitive to vibration. Test the spiders
and classify each as "wanderer" or "web-spinner". Then
use the handheld microscope to examine the claws and find out how accurate
the classification was.
- Your handheld microscope can be used to measure the air pollution in your
Hang a strip of 2" or 3" wide masking tape outside your window,
with the sticky side facing out. Leave it for a few days, so that it can pick
up particles in the air. Then bring it in and compare it (using a 50X or 100x
lens) to a fresh piece of tape.
You will see different types of particles on the tape that was exposed to
the air, and the quantity and size of these are one indicator of the quality
of the air in your area.
