Preschool science activities
How to nurture your child's interest in the natural world © 2008 -2012 Gwen Dewar, Ph.D., all rights reserved Can we design better preschool science activities? Activities that stimulate curiosity, teach science concepts, and avoid overwhelming or boring children with lessons that are developmentally inappropriate? In the article below, I review the advice of educational and cognitive psychologists about preschool science education. Floating and Boating is a set of science activities that encourage kids to play in the water, explore the concept of buoyancy, and make some cool contraptions. Dirt Lab is a set of activities that encourages kids to investigate the properties of dirt and mud. Animal tracking offers young children opportunities to exercise their spatial and scientific reasoning skills. Experiments with ice cubes introduce kids to aspects of the scientific method, as does this Brick-making activities allow kids the opportunity to make and test predictions. • how living things move

Perception puzzles, Visual Perception, Optical illusions and Paradoxes
This page illustrates that our visual perception cannot always be trusted. The components of an object can distort the perception of the complete object. Our mind is the final arbiter of truth. Most optical illusions are the result of 1) incongruent design elements at opposite ends of parallel lines, 2) influence of background patterns on the overall design, 3) adjustment of our perception at the boundaries of areas of high contrast, 4) afterimages resulting from eye movements or from kinetic displays, or 5) inability to interpret the spatial structure of an object from the context provided by the picture. The Parthenon Optical illusions have been studied for millenia. Perpetually ascending staircase. The red squares are the same color in the upper part and in the lower part of the "X" The diagonal lines are parallel. There are no gray spots at the corners of the squares. Stairway between corners of a flat square. The rows of black and white squares are all parallel. Impossible triangle.
Edheads
Support Teachers and Students in Need! Edheads motivates students to work harder in school by helping teachers connect their math and science lessons to real careers. By connecting school to work for students, particularly low-income students, Edheads changes lives and helps fill critical, in-demand jobs in engineering, cyber security and many other STEM (science, technology, engineering, math) careers. But Edheads needs support to accomplish our mission. By donating $20, $20 or more, you are not only supporting students and teachers in need, you are also helping Edheads create new games, AND getting a tax deduction, too. If you are a teacher wanting support for your classroom or school, please fill out and submit this form. About Edheads Edheads is an online educational resource that provides science and math games and activities that promote critical thinking. So search under the "Games" menu at the top of the page to dive into an activity and let the fun and learning begin! Latest News
