Activity # 1: Light Travels in a Straight LineActivity # 1: Light Travels in a Straight Line
Divide class into groups of 4
Teacher will prepare index cards by using a ruler to draw lines on
each card from one corner to the next forming an “X.” A hole will be
cut in each card where the lines intersect. The teacher will
demonstrate by standing a book on the desk. Then line up the index
cards approximately 15cm apart (standing it upright with the Mounting
Tack). The holes in each card will let the ray of light shine through the
holes in the cards. The light should be shining through all of the cards
onto the X. This shows that light travels in a straight line.
Teacher will then distribute materials for groups to begin their
experiments.
Students stand the cards up with the Mounting Tack, spacing them
about 15 cm apart, one behind the other so that they can see straight
through the holes. One of the students shines a ray of light from the
flashlight straight into the first hole and then into the hole from the
side. Next ask the students to (carefully) string the string through the
hole. Have one student hold onto one end firmly.
Students discuss among themselves what happens after each step
of the experiment. Students also move the cards so that they cannot
see straight through the holes, observing the results. Students are
to place a piece of white paper behind each hole on the cards, shine
the flashlight through the holes, what do they notice? Finally,
students place a piece of black construction paper behind each hole
on the card, shining the flashlight through the holes, discovering
that light can pass through some objects and not others.
Teacher gathers students and asks, “What changed when you
moved the cards? How did you make the light travel through the
holes in all three cards at the same time? What did you find out
about light? How do you know that light travels in a straight line?”
(Students will infer that when light travels in a straight path, it will go
through; but if the path is blocked, light will not keep going.)

  • 2. Activity # 1: Light Travels in a Straight LineActivity # 1: Light Travels in a Straight Line Divide class into groups of 4 Teacher will prepare index cards by using a ruler to draw lines on each card from one corner to the next forming an “X.” A hole will be cut in each card where the lines intersect. The teacher will demonstrate by standing a book on the desk. Then line up the index cards approximately 15cm apart (standing it upright with the Mounting Tack). The holes in each card will let the ray of light shine through the holes in the cards. The light should be shining through all of the cards onto the X. This shows that light travels in a straight line. Teacher will then distribute materials for groups to begin their experiments. Students stand the cards up with the Mounting Tack, spacing them about 15 cm apart, one behind the other so that they can see straight through the holes. One of the students shines a ray of light from the flashlight straight into the first hole and then into the hole from the side. Next ask the students to (carefully) string the string through the hole. Have one student hold onto one end firmly.
  • 3. Students discuss among themselves what happens after each step of the experiment. Students also move the cards so that they cannot see straight through the holes, observing the results. Students are to place a piece of white paper behind each hole on the cards, shine the flashlight through the holes, what do they notice? Finally, students place a piece of black construction paper behind each hole on the card, shining the flashlight through the holes, discovering that light can pass through some objects and not others. Teacher gathers students and asks, “What changed when you moved the cards? How did you make the light travel through the holes in all three cards at the same time? What did you find out about light? How do you know that light travels in a straight line?” (Students will infer that when light travels in a straight path, it will go through; but if the path is blocked, light will not keep going.)
