Lee, Jiwon; Cha, Yu Wha; Jung, Yeon Su; Oh, Eun Ju; Moon, Ye Lin; Kim, Jung Bog – Physics Teacher, 2016
Melton demonstrated a surprising disappearance using total internal reflection. When he put a Florence flask filled with marbles into a water tank and looked straight down from directly above the flask, he was only able to see marbles above a certain water level. When he added more water into the tank above the top line of the marbles, all of the…

Nagel, Bert – Primary Science, 2015
Marble tracks are a very popular toy and big ones can be found in science centres in many countries. If children want to make a marble track themselves it is quite a job. It takes a long time, they can take up a lot of space and most structures are quite fragile, as the materials used can very quickly prove unfit for the task and do not last very…

Denman, Richard T.; Hailey, David; Rothenberg, Michael – College Mathematics Journal, 2010
The Catseye Marble company tests the strength of its marbles by dropping them from various levels of their office tower, to find the highest floor from which a marble will not break. We find the smallest number of drops required and from which floor each drop should be made. We also find out how these answers change if a restriction is placed on…

Lubrica, Joel V. – Physics Education, 2016
This paper presents one way of demonstrating the Principle of Equivalence in the classroom. Teaching the Principle of Equivalence involves someone experiencing acceleration through empty space, juxtaposed with the daily encounter with gravity. This classroom activity is demonstrated with a water-filled bottle containing glass marbles and…

Mungan, Carl E. – Physics Education, 2015
What trajectory in the laboratory frame does a marble follow if it is held inside a freely rotating pipe and then suddenly released so that it can slide frictionlessly outward along the pipe? A previously published solution is only valid for a pipe of small moment of inertia (so that it is either low in mass or short in length).

Holub, Jordan; Kruse, Jerrid; Menke, Lucas – Science and Children, 2019
In this article, the authors focus on students constructing observations of patterns to understand how surfaces affect the motion of an object. Students will use the patterns they observe to predict future motion of marbles (NGSS Lead States 2013). Students then apply their learning by engaging in an engineering task. By giving students a task to…

Hosey, Dan – Physics Teacher, 2019
The High Road/Low Road race is often used as a qualitative prediction activity. A marble is released simultaneously on two elevated tracks that differ only in the middle section where the Low Road dips before finishing at the same height as the High Road. Typically a minority of students correctly predict that the Low Road will finish first. In…

Metcalf, Jennifer L.; Atance, Cristina M. – Cognitive Development, 2011
Using a new paradigm for measuring children's saving behaviors involving two marble games differing in desirability, we assessed whether 3-, 4-, and 5-year-olds saved marbles for future use, saved increasingly on a second trial, saved increasingly with age, and were sensitive to the relative value of future rewards. We also assessed whether…

Ashbrook, Peggy; Nellor, Sue – Science and Children, 2015
Engineering is such a common part of children's work in early childhood programs that teachers can simply look around the room to identify examples where students have engaged in engineering practices. This article presents a classroom activity that integrates engineering design by building on the everyday problems that young children encounter in…

McCormick, Kelly K.; Essex, N. Kathryn – Teaching Children Mathematics, 2017
This article reports on a study in which researchers asked children to "make up as story and a picture about marbles for this number sentence: 3 x 5 = 15." Students in this study came from pre - dominantly low- to average-income families living in three distinct geographical areas within the United States. A similar division task was…

Ashbaugh, Henry S. – Chemical Engineering Education, 2010
Successful teaching of the Second Law of Thermodynamics suffers from limited simple examples linking equilibrium to entropy maximization. I describe a thought experiment connecting entropy to a lottery that mixes marbles amongst a collection of urns. This mixing obeys diffusion-like dynamics. Equilibrium is achieved when the marble distribution is…

Looijenga, Annemarie; Klapwijk, Remke; de Vries, Marc J. – International Journal of Technology and Design Education, 2015
Iteration during the design process is an essential element. Engineers optimize their design by iteration. Research on iteration in Primary Design Education is however scarce; possibly teachers believe they do not have enough time for iteration in daily classroom practices. Spontaneous playing behavior of children indicates that iteration fits in…

Hoorman, James J. – Journal of Extension, 2014
There is a renewed interest in educating youth, Master Gardeners, and agricultural producers about soil quality. Three soil demonstrations show how soil organic matter increases water holding capacity, improves soil structure, and increases nutrient retention. Exercise one uses clay bricks and sponges to represent mineral soils and soil organic…

Hughes, Stephen W. – Physics Education, 2010
In this article some basic laboratory bench experiments are described that are useful for teaching high school students some of the basic principles of stellar astrophysics. For example, in one experiment, students slam a plastic water-filled bottle down onto a bench, ejecting water towards the ceiling, illustrating the physics associated with a…

Kuzmak, Sylvia – Statistics Education Research Journal, 2016
Teaching probability and statistics is more than teaching the mathematics itself. Historically, the mathematics of probability and statistics was first developed through analyzing games of chance such as the rolling of dice. This article makes the case that the understanding of probability and statistics is dependent upon building a…
