Constructivist science activities on ECE level with water concepts and nature table

"Research and practice suggest that children have a much greater potential to learn than previously thought, and therefore early childhood settings should provide richer and more challenging environments for learning. In these environments, guided by skillful teachers, children’s experiences in the early years can have significant impact on their later learning. In addition, science may be a particularly important domain in early childhood, serving not only to build a basis for future scientific understanding but also to build important skills and attitudes for learning." from Karen Worth's article Fall 2010 "Science in Early Childhood Classrooms: Content and Process"

Science activities that allow children to explore and build their knowledge and skills is the premise for this post:

Examples:

1.  image from The Mailbox--2nd and 3rd grade level electronic newsletter--water depth and pressure experiment; place a soda 2 liter bottle with 2 holes taped over then filled with water and sealed into a tub kind of bin or pan; remove tapes at same time while asking the children to guess where the water will come from first; and ask them why it happened where it did

2. image from The Mailbox--2nd and 3rd grade level electronic newsletter--condensation phase of water cycle experiment; add water to the fill line on the cup; seal tight in the plastic bag; place in a window that gets good sunlight (solar heat); when will evaporation (and later--how much evaporates) take place...can children see the condensation?

3. the water station exploration activities photo is from www.nstacommunities.org; retrieved online 5/4/2019; children can explore gravity and flow; volume with different sizes of containers and funnels; even a sponge can be saturated and see how much can be squeezed out and measured

4. this next example is not to shame the website Education.com but to show how a worksheet can be the inspiration or springboard for a teacher to guide her/his children's curiosity 

Cut apart the images, laminate or place inside sealed clear plastic bags and display on a wall or tabletop where children can do sink and float comparisons. A bowling ball (pink item with 3 holes) is not practical for an indoor classroom environment so make that one a button; same for the log--impractical but a twig would be ideal; a small apple; a rubber duckie; key; and horseshoe magnet complete the list of items.

 A large clear storage tote filled about 1/3 with water should be enough to either suspend or not these objects.

 Place a large beach towel or shower liner underneath in case a child or two are exuberant with putting items into the water.

 Extend the exploratory time during the next couple of sessions by asking children for suggested classroom items to try. (crayon, pencil, wooden spool vs plastic spool; paper clips of different sizes; plastic lids; etc.)

My understanding and application of the constructivist theories in cognitive development is to allow children opportunities to explore and experiment with the teacher guiding and providing materials first. Then as youngsters are asking questions and showing desire to change, inspect, and analyze, vocabulary, facts, data, and skills can be shared later. For the above sink or float activity, gravity and buoyancy are large words for little ones. How can those be defined in basic terms?

Are daycare centers, preschools, and primary elementary grade classrooms still allowing exploratory learning?

Or has this disappeared under the 'umbrella' of testing and assessment?

Let me know in the comments on how early childhood science is approached.

Suggested bedtimes for little ones

Just not for children in daycare or preschool or school settings

Young children tend to rise early so they need to be in bed ready to sleep at these times.

It is not fair to the family dynamics if you force all the children in the household to go to bed at the same time. Children require more sleep than adults. And by teen years, their body clocks sometimes shift and some require as much sleep as preschool-age and others will shift to late night owl status but struggle to be perky at 7 a.m. The educational and medical communities of professionals agree that there are ages and stages for developmentally appropriate practice. These bedtimes are part of that DAP for preschool and kinder age children:

Age..................................... Suggested bedtime
3.....................................................7:15 p.m.
4.....................................................7:30 p.m.
5.....................................................7:45 p.m.
6.....................................................8:00 p.m.


For each birthday milestone after age 6 continue to add 15 minutes. I've seen some children put themselves to bed long before their usual time and even before either parent hints that it's getting close to beddy-bye time. If they are tired from being out of routine, make an adjustment with an earlier bedtime for a night or two. Same for when they are sick, battling a new tooth cutting in, having leg cramps due to a growth spurt, bedtime may need adjusted to an earlier time.

Also children like to have structure and a routine for bedtime, so try to keep that consistent, too. They feel secure and loved when consistent household routines are kept. Laying out clothes for next day, putting on pajamas, brushing teeth, washing face, reading a book or listening to a lullaby tape, dim the lights, and then tucked into bed with a kiss and a hug.

Pleasant dreams.
