Today’s agenda
Complete reading and question activity
from yesterday (UV exposure and skin
cancer)
 Review Skin Cancer article / questions
 Radiometer Experiment
 Web Quest activity – focus on either the
infrared region, visible light region or UV
region of the electromagnetic spectrum

Independent Work
You will work on a chromebook for 20
minutes to complete yesterday’s activity
related to the Ozone Layer, UV radiation
and skin cancer
 This was the reading and the questions

Review Skin Cancer reading ….

Let’s review these questions together
now….
What is a radiometer

Read page EN 21 (top paragraph only)
What is a radiometer?
 Draw
this picture
now!
 Pay close attention
to the color of the
flags inside the
radiometer
Radiometer Experiment – draw this
table
Conditions

classroom
Outside in

Radiometer Observations Handout
You will now see 3 different
demonstrations
 We will have to walk outside to complete
2 of the observations
 You will need to take your notebook and
a pencil with you
 Does anyone have any questions?

Radiometer Observations
let’s review
Observations
Sitting on the cart, the
flags did not move
Sitting in the shade, the
flags spun slowly
Outside in the sun, the
flags spun very fast
How does it do that?

Let’s Read page EN 24 together now
What caused the flags to start
spinning?
Think about the colors of the
flags…
 Black absorbs energy
 White reflect energy
 This causes the air inside
the radiometer to heat up
differently. This causes the
air inside to start moving.
 This moving air causes the
flags to spin!

Radiometer Observations Handout
Causes
There was no radiant
energy in our classroom
There was only indirect
radiant energy the shade
There was direct radiant
energy on the radiometer
Radiometer Observations Questions
Copy each question and answer silently in
your notebook:
1. What happened to the flags outside in
the sun?
They started to spin very fast
1. What might the movement of the flags
be an indicator of?
Radiant energy
Radiometer Observations Questions
4.
What can we infer from our
observation? The radiometer transfers
radiant energy into kinetic energy which
makes the flags inside spin
Glue this into your notebook now
Let’s Analyze the Data
 Turn to page
 Answer only
EN 23 –
Question 1 at the
bottom of the page
 You and your table partner may
work together
 EVERYONE MUST WRITE THE
QUESTION AND ANSWER IN
YOUR NOTEBOOK

research your specific area of the
spectrum and you will share your results
together in class

Web Quest Activity
You will receive your handout now
 Put your name on your paper
