Activity: Oobleck

Activity Plan

Number of Children: 1 to 4

Age Range of Children: 2.6 to 3 years

Originating Idea Based on Observation:

At the book area, the children chose stories they wanted to read. Child V gave me One Family just as Child Q tried to give me a different book to read. I told Child Q that we will read her book after Child V’s. While reading aloud, I pointed at the pictures and described what the book is about. Child R came closer and turned the page of the book for me. Child Q also came up and wanted to change the page. Then Child V also showed interest in turning the page himself. I told the children that they may do so after we read what is on the page. I also reminded them that they are to take turns since only one child can turn the page at one time.

This activity will support the children’s interests in independence and their desire to help while developing their observation skills.

Learning Anticipated & Developmental Significance:

COGNITIVE DEVELOPMENT

“4.5 Observing

  • using all senses to gather information while observing
  • focusing their observation on details
  • increasing the time they spend observing”

(Best Start Expert Panel on Early Learning, 2007, p. 53)

G) Science and Technology

“43. Observing: Children observe the materials and processes in their environment”

(High Scope, 2010)

Where & When Will the Activity Take Place

  • at the Sensory Area
  • during Work Time/Program-Planned Activities

Materials

  • water
  • corn starch
  • food dye (diluted in water; red, yellow, blue)
  • jars (4, small-sized)
  • bowls (2, medium-sized)
  • droppers (6)
  • vials (6)
  • spatula
  • measuring cups
  • baskets (4, plastic, small-sized)
  • shoe box (plastic)

Beginning

Labels
  • Place lables on the jars and vials as such:
    • jars: water x 2; corn starch x 2
    • vials: red x 2; yellow x 2; blue x 2
SET UP
  • Recipe
    • 2 cups of corn starch + 1 cup of water + a few drops of food dye
  • Place two medium bowls on each end of the sensory bin. Set the jars of water and corn starch around each bowl in such a way that two children can create oobleck in each bowl.
  • Place the vials of colour in the middle of the bin for both groups of children to share.
TRANSITION/INTRODUCTION
  • Invite the children to look at the ingredients and describe what they see, smell, or feel as they explore them.
  • Have each child place the corn starch, then the water, into the bowl. Ask them to choose a colour each, and allow them to add a few drops of dye into their mixture.
  • Encourage the children to stir the mixture with their hands.

Middle

  • The children will mix the ingredients and explore the oobleck by running it through their hands. I will ask the children to describe how it feels and what they see is happening.
  • Other children may not like how the oobleck feels, but I will encourage them to explain why and assist them in describing how the oobleck felt (e.g. cold, slimy, powdery, etc.)

End

WARNING
  • Five minutes before the end of the activity, I will tell the children that we will give the other boys and girls a chance to play with the oobleck. Or that we will be cleaning up soon to get ready for the washroom.
  • I will let them know that the materials will be available again during the next work period.
Clean Up/TRANSITION
  • I will ask the children to place the oobleck that they made into the shoe box. We will let it air dry before sealing and putting away.
  • I will assist each child in cleaning their hands with a wet towel before heading to their next activity.

Observations & Reflections

  • The children picked up the droppers as soon as they got to the sensory bin.

oobleck-4

  • Child O dipped his palm into the goop and wiped it off his bracelet right away.

oobleck-3

  • As Child L submerged her hand into the goop, she said, “It tickles!”
  • The children asked for “more water” as they raised the container they were holding. Child B also made a scooping motion into the sensory bin as she demonstrated there needs to be more water.

oobleck-2

  • Child E said, “I’m making pizza! . . . and cupcake!”
  • Child S placed the small container into the opening of the jar and poured some goop into it.

oobleck-1

  • I feel good about choosing a sensory activity because it engaged the children in such a way that they did not want to leave the activity area.
  • I struggeld with creating the right consistency of oobleck and having the children explore this particular material. I could have created the oobleck for the children and have had them explore what they can do with it.
  • Being firm with the children’s time at the sensory bin helped ensure that each of them had a chance to try the activity.
