In education, "Industrial Revolution 4.0" refers to utilizing technology to present students with complex situations that will develop their critical thinking and problem-solving skills. The use of technology in the science curriculum should be designed according to established learning models. This study aimed to investigate the effect…

The Periodic Table of Elements is a valuable resource for chemists and all kinds of STEM professionals. However, it can be initially overwhelming and intimidating to some students. This hands-on lesson introduces abstract concepts in the periodic table through a tangible experience with simple toys and household objects. Students collaborate and…

The impulse to investigate the natural world is deeply rooted in our earliest childhood experiences. This notion has long guided researchers to uncover the cognitive mechanisms underlying the development of scientific reasoning in children. Until recently, however, research in cognitive development and education followed largely independent…

Describes exploratory activities for a young child seeking to become acquainted with the world in which he lives. (EB)

First of a series showing ways in which the preschool setting can provide exploratory activities for the young child seeking to become acquainted with the world about him. Suggests ways to present the concepts of climate, clean air, personal space, and noise level. (EB)

Supports the approach for young children that allows them to perform actions on objects and observe the reactions. Describes some techniques to use to encourage an inquiry approach. (DDR)

This unit emphasizes concept-learning through the discovery approach and child-centered activities. "Discovering Matter" is treated in the kindergarten, "Matter Around Us" in grade 1, "Changes in Matter" in grade 4 and "Atoms and Molecules" in grade 6. The unit for each grade contains (1) understandings to…

Some ways in which exploratory activities of the preschool child involve science concepts are described. The role of adults knowledgeable about both science and child development is stressed. Emphasis is placed on hands-on experiences. (EB)

Reports on a study that explored the types of questions that students ask for open-ended science investigations. Discusses how teachers can help students identify problems and pose questions that are feasible for investigation. (Contains 55 references.) (DDR)

Demonstrations are presented in which children can be introduced to evidence of specific concepts enabling them to participate in such a way that any conceptual conflicts that might arise in this learning situation can be gradually reduced. (EB)

Presents activities that utilize balloons to encourage students to explore questions related to scientific concepts. Concepts explored include light, heat, charged ions, polarization, and the sense of smell. (MDH)

Describes a unit on magnetism that utilizes hands-on activities in which students make hypotheses for discrepant behavior, discover whether a magnet attracts one object through another, measure the strength of magnets, explore levitating paper clips, and play a game dependent on magnetic attraction. (MDH)

This curriculum guide, part of a series of science units, stresses concept-learning through the discovery approach and child-centered activities. It is intended that the unit will be studied in depth by grades 3, 4, 5, and 6. Kindergarten pupils will study the unit in less detail. "Our Useful Rocks" is studied in the kindergarten,…

This curriculum guide, part of a series of science units, provides for differentiation of emphasis of subject areas at different grade levels. It is intended that the unit will be studied in depth by grades 1, 4, and 6. Kindergarten, grades 2 and 3 will study the unit in less detail. "Our Wonderful Sun" is studied in Kindergarten, "Earth in Space"…

Describes the construction of durable, inexpensive and large sand-hourglasses for use in controlled experiments that allow students to observe, infer, measure, record data, and predict. This hands-on activity is designed to take place over a three-day interval. Includes materials needed, techniques, procedures, follow-up activities, and resource…
