The Value of Loose Parts
This past summer and fall, the Iowa Regents' Center for Early Developmental Education had the privilege to spend learn with more than 160 Iowa educators by exploring open-ended STEM experiences involving light and shadow phenomena. Several of these experiences involved loose parts. The idea of providing young children with loose parts was initiated by British architect, Simon Nicholson as a way for children to interact with variable such as gravity, sound, science concepts, words, and people. Engaging with open-ended loose parts offers a sense of wonder to children and nurtures invention, divergent thinking, and problem solving. We encourage teachers to provide opportunities for children to work with loose parts on a light pad, using light as a tool to reveal details in human made and natural objects, discover patterns, and create their own patterns using loose parts. When PK-2 children handle loose parts, they call upon their five senses as well as their senses of weight and balance. They discover properties of the materials, and how those properties determine how these materials can be used.

What Babies Can't Learn from Screens by Dr. Jill Uhlenberg
What babies can’t learn from screens:
1. Sensory development. How things (I am including people here!) taste, smell, feel. While screens can provide sound and colors, they limit the full sensory experiences involved with real objects.
2. Textures. Again these can be depicted visually but screens cannot engage children with differences in textures other than visually.
3. Depth perception. Very young infants begin their understanding of space with the concepts of near and far. On a screen everything is the same distance from the infant—distant objects are smaller and nearby objects are larger, but this may just be size rather than closeness.
4. Separation of objects. On a screen, everything is all part of one thing—the screen. Real objects are separate from each other. Infants learn that objects are separate by grasping and handling them.
5. Object permanence. This begins early in life through learning the continuity of objects. By turning objects in their hands, babies learn that the object continues on different sides.
6. Object constancy. A solid object’s size and shape does not change. On a screen we can easily enlarge or reduce these. This is the beginning of concepts of conservation.
I admit to allowing my grandchildren use of tablets and other screens. However, my goal has been to ensure that more time is spent with real people and objects than screens. Francis and Whitely (2015) report that young children do not readily transfer knowledge about two-dimensional objects to three-dimensional objects. They need practical experiences examining all kinds of objects in order to develop astrong understanding of spatial reasoning.

The Other Side of Math for Infants and Toddlers by Dr. Jill Uhlenberg
• One-to-one correspondence—one ball fits in one cup;• Estimating space—using the medium ball in the medium-sized muffin tin; noticing which balls fit and which did not; pouring a bowl full of balls into a too-small canister; trying to place a lid on a too-full container;• Classification—sorting balls by color or size; older preschoolers may use two characteristics, but infants and toddlers can generally only sort on one attribute;• Patterns—placing balls in the muffin cups in a particular order (color, size, selected cup, etc.) that is repeated;• Distribution—performing the same act on the same materials repeatedly, like placing the same ball in each of the muffin cups one by one; this mathematical process shows up later when adults are calculating equations.
combining materials in creative ways by constructing towers of bowls, canisters, nesting containers, and other objects. These explorations lead logically into the use of blocks, another strong component of spatial understanding. When you recognize and celebrate infants’ and toddlers’ bent for objects and containers, you are supporting their beginning spatial understanding. You will be surprised at the wealth of knowledge they construct over their first three years.

Toddlers and STEM Experiences: Adults as Learners
The struggle to find out the material world through science, technology, engineering, and mathematics (STEM) begins at birth. Lucky are the infants and toddlers who have observant, caring adults who support STEM learning from the start.
This is the last in a series of four blog posts written by Dr. Jill Uhlenberg who describes four types of effort adults can employ to nurture STEM from the beginning.
technology, engineering and mathematics. Many toddler teachers are very unsure of their ability to offer technology and engineering experiences to their children. If we accept that technology is NOT limited to screen time, this becomes much easier to understand. Technology is the tools we use to complete a task or solve a problem. The paper taped to the classroom table in my first blog entry is technology - the teacher solved the problem of paint dripping down the classroom easels by providing a horizontal surface for the children to paint. The sippy cups I wrote about in the second blog entry about curriculum development also would be considered technology. And engineering is the process we use to address those problems that we find and solve.
Although there are many more kinds of effort toddler teachers must expend each day, from hugs, supporting toilet learning, supporting parents, documenting, clean-up, and more, engaging in these four kinds of effort produce high quality experiences for children. All four roles—liberator, curriculum developer, chief historian, and learner—interact to support toddlers in their exploration of STEM experiences.
