A simple inquiry-based activity called "Fruit Puzzle" was designed to investigate high school students' understanding of the relationship between the concepts of density and solution concentration at a submicroscopic level. The first activity allowed students to predict whether five types of fruit would sink or float in water and asked…

Chemical escape rooms (ChEsRms) are educational games in which students use their brain, chemical knowledge, intuition, and a bit of luck to solve a mystery. At the Weizmann Institute, we have developed ChEsRms that are implemented by teachers in their classes. Since the COVID-19 pandemic stopped all the educational activities that took place in…

Small-scale science activities provide an opportunity for engagement of diverse, large audiences at settings such as 4-H fairs. We present practical information for implementation of small-scale food science experiences in the Extension education context. Our focus is description of a tool for adaptation of activities for inquiry-based learning…

An escape-room-game activity was introduced to foster team building and collaborative learning in a laboratory-experiment setting. The students were placed in a laboratory with clues and puzzles that required the students to use a sequence of analytical instruments in the laboratory in order to escape. The instruments utilized included a UV-vis…

There is an increasing emphasis on fundamental particles, including quarks, in the high school physics classroom. However, many teachers might not feel comfortable teaching particle physics because it is a highly abstract and complex topic, and there are few hands-on activities to help teachers bring it into the classroom. In 2010, a…

Data-driven methods have been a successful approach to generating hints for programming problems. However, the majority of previous studies are focused on procedural hints that aim at moving students to the next closest state to the solution. In this paper, I propose a data-driven method to generate remedy hints for BOTS, a game that teaches…

Sustainable, or "green," manufacturing and its practices are becoming more and more a part of today's industry, including wood product manufacturing. This article provides introductory information on green manufacturing in wood technology and a crossword puzzle based on green manufacturing terms. The authors use the puzzle at the college level to…

This paper provides nine short chemically based puzzles or problems extensible for use with students from middle school to college. Some of these will strengthen students' recognition of individual elements and element names. Others require students to focus on the salient properties of given chemical elements.

Erwin Raisz's Landform Map of the United States, a popular teaching aid in geology and geography courses, is available as a jigsaw puzzle. Indicates that puzzle assembly represents a unique way to expose students to the physiographic features of the map without the need for written exercise material. (BC)

A study uses a thought-provoking, pencil-and-paper activity to aid students in writing organic reaction mechanisms. Organic and functional groups that constitute the formulas of organic and inorganic reactants, ionic intermediates, and products are presented as building blocks, which must be placed correctly in a given puzzle so that they bind…

Suggests the use of a body puzzle as a student-centered and economic way of teaching human anatomy. Provides a full page diagram of the body with illustrations of selected organs. Lists activities that can serve as the basis for inquiry into the structure and function of the human body. (ML)

Described are 15 events that take place during a physics olympics at a Michigan high school. These events are planned with the idea of involving the older students in designing and presenting projects to ninth graders, and involving the latter in a day of outdoor participation. (SA)

Reviews the benefits and hazards that the sun provides. Describes activities which focus on the power of the sun and on the development of "Sun-sensible" behavior. Also included is a poster which contains puzzles and additional information and activities on safe sunning. (ML)
