Procedures/Activities:

     Introduction (3 minutes)

Teacher will introduce lesson by playing a song about rainbows, and then asking learners where they have seen a rainbow. After this, learners will be informed that they will see a rainbow in the classroom.

 

    Lesson Body (20 minutes)

i.         Assessment: Learners will be asked to color in a rainbow template; teacher will place multiple colored crayons in front of each learner. Each learner will be given the colors seen in rainbows and two neutral colors.  Data will be taken on whether learners use different colors.

 ii.         Teacher will show learners a sequence of events that create a rainbow and will explain that rainbows are usually seen after a rainstorm. This is because the water bends the sun's light, creating all the colors that they see on the wall, in the shape of a rainbow. The teacher will demonstrate the difference between a straight light beam, using a flashlight, and a bent light using a flashlight and mirror.

 iii.         Teacher will then tell learners that they are going to make a rainbow on the wall. Teacher will take out a large glass bowl and a mirror and demonstrate how to make a rainbow. Each learner will have a turn to create their own rainbow. Teacher will ask what colors they see. Each learner will have a pile of color cards in front of them. Learners will select and name the colors they see in the rainbow and place them on the rainbow template. Once all students have had a turn, the teacher will review with the learners what they saw and what colors they were able to see in the rainbow. Learners can refer to the colors placed on the template to help with recalling information.

 iv.         For an activity, learners will be able to create their own rainbow on a slice of bread. Learners will each be able to add 7 drops of food coloring to a cup of milk. Learners will be instructed to use their paintbrush and colored milk to paint a rainbow in their bread.  Learners will be given some sugar to sprinkle over the bread and the bread will be toasted.

Note: Teacher will pour ¼ cup of milk in each plastic cup and add food coloring to make different colors.

 Closure of Lesson (7 minutes)

   i.         Teacher will assess learners on different skills. For LK, teacher will present 3 sequence cards and ask him to place them in order, by gluing them on a template. For LC and JS, teacher will ask them to circle 4 colors that they observed in the rainbows from a field of 8 colors. These assessments will serve as permanent products for evaluation.

   ii.         Learners will be allowed to eat their rainbow toast, once their assessments are complete.

Materials/Equipment:

 
  • a. Visual Cues
  • i. Schedule board
  • ii. Rule board
  • iii. Sequence of events for a rainbow
  • iv. Rainbow template for initial assessment
  • v. Crayons
  • vi. 3 sets of color cards

Assessment Guidelines:

 

Different assessments will be used based on learners' skill levels. One learner will be assessed on a sequencing task, and the other two learners will be assessed using a worksheet with multiple colors and will be asked to circle the correct colors.
