Physics in preschool


Young Children March 2012

Problem solving and physics: any subject can be taught effectively in some intellectually honest form to any child at any stage of development

Too often, curriculum planning focuses on interests but fails to incorporate the process of learning such as problem solving, experimentation, theory, building and making predictions

Inquiry-based planning focuses on the process.  It is hands-on and minds-on

·         Such as: making comparisons with pre made shakers vs. allowing the students to fill the shakers, make predictions, listen

·         Minds-on: experimentation, hypothesizing, problem solving and as a result are thinking, reflecting and communicating

·         Give them a problem to solve so they have a purpose and you can introduce variables

o   Lift a lion

o   Make a mouse house

o   Shaker with a low sound like the voice of the lion in the story or high sound for the mouse

Problem solving: more than free exploration with great tools

What will happen if I swing the pendulum harder?

How can I get the water from the sensory table to the bucket using these tubes

Force and motion: how does it move?

Putting it all together

1.       Define the problem: pose the problem or set up the challenge

a.       how can we make the marble change directions (without marbleworks or curved pieces)

b.      I wonder if there are other directions that we can make the marble travel besides up and down? (left/right). 

c.       Demonstrate the reason: If the ramp is against the wall, it would need to turn the corner

d.      Help them stay focused

2.       Develop a procedure

a.       Encourage communication

b.      Offer clipboards, paper, markers, journals, clay etc to represent thinking and recording ideas

c.       Draw the ramp plan: think about additional materials needed

d.      Book: roll, slope, slide  to connect for  additional ideas

3.       Conduct the procedure

a.       Test and retest

4.       Draw conclusions

a.       Often overlooked: discussion of discoveries (reflections): are they happy with solution? Is there another or better way to solve the problem?, documentation/assessment

b.      Use representations of work or drawings as a springboard for talking about their ideas

Asking good questions

·         Acting on objects to see how they react.

o   See what you can do with these

o   what would happen if you connected the two pathways

o   What would happen if you put another block under the ramp?

·         Acting on objects to produce a desired effect

o   Ask questions to build on initial experiences and ideas

o   I wonder how you could make the ramp longer

o   How could you help kyle make the marble move faster

·         Becoming aware of how one produced a desired effect

o   Age 4-5 are able to do many things with practical intelligence but are not aware of how they produced a result because explanations must go beyond what is observable.  Difficult for them to explain why something happened

o   How did  you do that

o   I wonder how that happened

o   Tell me about the blocks you used to make your marble go this way

·         Explaining causes: encourage them to talk to each other about their ideas

·         Wow, that’s a great idea.  Can you tell stella how you did that?

·         ‘wonder’ out loud: I wonder why the marble falls off the ramp and doesn’t turn

·         Know when to intervene: mostly when thinking is stalled by providing specific materials, encouraging collaboration, help focus on details. 

·         when you know something will not work, let them think it out

Criteria for planning physical knowledge activities

1.       Children must be able to produce the movement by their own action

2.       Must be able to vary their actions

3.       The reaction of the objects must be observable

4.       The reaction of the objects must be immediate

Vary the materials

·         Building blocks,

·         ramps or pathways, (cove molding, carpet roll tubes)

·         pendulums, (yarn, tape, crumpled paper)

·         pulleys,

·         mazes,

·         rollers,

·         water play with tubing or containers with holes

·         texture, size, quantity

vary the inquiry

·         balance,

·         roll,

·         swing,

·         push,

·         pull,

·         tilt,

·         slide,

·         dump,

·         throw,

·         blow on,

·         drop,

·         flick
