This natural science lesson introduces magnets and magnetic
properties through games and activities. Because some FasTracKids classes
are located in areas of high humidity, some of the experiments may not
work as well as shown on the Learning Station. Use this opportunity
to discuss this factor and talk about different climates and how they
determine many things, including static electricity. This lesson requires
a large number of supplies, but all are easy to obtain and can be kept
for other lessons or uses.
Note - when discussing magnets, if a large magnet is used, remember
to keep it away from the computer.
"Setting the Stage" - Before starting the program,
ask the students: Do you use magnets at home? How? Have you ever felt
a shock when you've touched a doorknob?
"Magnets and Static Electricity"
Hands-on activity - As the lesson is introduced, students are
encouraged to think like scientists. To emphasize this, students color
and create their official FasTracKids science name tags. As they create
their nametags, talk about what scientists do and why.
"Magnets in Our Daily Lives"
To start the lesson, magnets are shown as they are used in our daily
lives.
Touch-screen game - a variety of items are presented on the Learning
Station. Students are instructed to decide whether they think each item
is magnetic or not. This will give the teacher an idea as to how many
children already understand magnets. Because some of the answers are
quite obvious, it is a good opportunity to encourage the shy or new
child to use the Learning Station.
"Magnet Experiment"
Hands-on experiment - The items listed at the end of this page
are listed in the narration. Other items may be used as determined by
the teacher. Provide a good variety to create an enriching experiment.
Divide the class into teams or pairs. As instructed by the narration,
students put the items into two separate piles, classifying them as
magnetic or not magnetic. Emphasize to students that they are classifying
objects in a scientific manner. This is also reinforced by the Learning
Station narration.
"Magnetic Force"
Touch-screen - This game on the Learning Station reinforces what
the students have just learned during their experiment, as well as the
concept of classifying. Students choose which items are magnetic and
which are not.
"Create Your Own Action Figures"
Hands-on activity - This activity encourages students to work
as a team and use their imagination, as well as creativity and presentation
skills. Divide the class into two groups if it is a small class, or
four groups for a larger class. The "A" group will draw a rainbow (as
instructed on the Learning Station) on a large piece of stiff paper
or poster board. The "B" group will color the action figures (paper
dolls/characters) and attach large paper clips to their bodies. As they
are coloring and creating, students should decide upon a simple story
to tell about their characters. The teacher may want to give some guidelines
if the children have difficulty, such as what their characters are doing,
how do they feel about the rainbow, etc. Do not restrict the story to
a rainbow, though, as some children may want spaceships or animals in
their story. When they have completed their story and art projects,
they will present their stories to the rest of the class. Using the
magnets (make sure they are strong magnets) on the back of the poster
board, move the characters with the paper clips on the front of the
poster board to create 'action'. These instructions are given in the
narration with an example. This sounds more complicated than it is,
and children loved the process during field testing, so review the disk
prior to class time to determine how many groups will work best for
your class.
"Magnetic Force in Your Own Body"
A video clip demonstrates how static electricity occurs in our bodies.
This can be recreated by the class if the teacher desires, but health
concerns should be a consideration. Also, as the narration indicates,
some climates and hair textures will make this less effective.
"Pen and Wool Experiment"
Hands-on activity - Provide wool fabric (squares or pieces are
sufficient) to rub a plastic pen across. As directed by the narration
on the Learning Station, students rub plastic pens rapidly across the
wool, then attempt to pick of the pieces of newspaper. Make sure the
newspaper is in small pieces, similar to confetti. The students must
follow the directions carefully as presented. Remind them that they
are scientists. (this will make the teacher's job easier, too). Students
enjoy this activity and should be encouraged to explain what they are
discovering.
*Do not put the wool and paper away, as it will be used again shortly
for another experiment.
"Scott and the Magnet"
A short story about Scott and his sister is presented to illustrate
the damage a magnet can do, even though it cannot be seen. Encourage
the students to listen to the story and answer the questions as presented.
"Magnetic Force Transfer"
Hands-on activity - using the large magnet and a pile of paperclips,
follow the instructions given by the narration. This experiment will
demonstrate how the magnetic force is transferred through a row of paper
clips. The larger the magnet used, the easier the experiment is to conduct.
This can be performed in groups, or as a demonstration by the teacher,
depending on class size and time remaining.
"Balloon Experiment"
Hands-on activity - using the same bits of shredded newspaper
and wool, another experiment is provided. Students rub the inflated
balloons across the wool, similar to the pen experiment, and attempt
to pick up the pieces of paper. The balloon will attract the pieces
of paper.
Touch-screen activity - Many children already know what will
happen if they rub their hair. This is presented in a short video image
after it is activated by choosing the icon as directed by the narration.
Encourage the students to listen to the narration carefully.
Videotaping activity - the activity to videotape is included
at the end of this lesson so that the teacher can determine, if another
would be preferred, which activity would be best for each individual
class. This is a 'busy' lesson and a number of activities are provided
that would create great videotaped presentations.
