Hi Fenway here. Today i am going to tell you about my first science experiment in grade 4 about how light travels .

Hypothesis:

I think that the light will travel fast in a straight line. If there is no hole in the card this will stop the ray of light

Procedure:

1)gathered my material

2)drew a x on cards and then bullseyes on one and used my pencil to make a hole in the center of each card

3)put clay on bottom of card tp stand up

4) made sure the cards were 15cm apart

5)shine a flash light through the holes to hit the bullseye
