• Supporting Materials: The page includes sections for "Sample Learning Goals," "For Teachers," "Research," and "Video," although these sections are currently empty ("[texthttps://www.um.es/fem/EjsWiki/", further reinforces this.
• Focus on Inquiry and Interactive Learning: The presence of numerous interactive simulations and the mention of "how to make SLS lessons more inquiry-based?" in one of the linked resources (20180117 11th IPSG) suggest a pedagogical approach that emphasizes active learning and exploration.

2. Excerpts from "Newton's Law of Cooling"

Main Theme: This excerpt identifies the topic as "Newton's Law of Cooling" and credits the same authors as the cooling and heating simulation.

Key Ideas and Facts:

• Topic Identification: The title clearly states the focus is on "Newton's Law of Cooling," a fundamental concept in thermodynamics that describes the rate of heat loss of an object is directly proportional to the difference between its temperature and the ambient temperature.
• Shared Authorship and Copyright: The consistent authorship ("Wolfgang Christian - Davidson College; Sze Yee; lookang; shaun quek") and copyright information ("© 2021") across both resources indicate a connected development effort.
• Software Used: The statement "Compiled with EJS 6.1 BETA (201115)" explicitly mentions the software used to create this resource, likely an interactive simulation or model demonstrating Newton's Law of Cooling. This reinforces the potential connection to the "Cooling and Heating Curve" simulation as both might utilize the same toolkit.
• Open License: The phrase "Released under a license" (while the specific license is not detailed in this excerpt) suggests that this resource is also likely shared under an open license, aligning with the platform's overall OER nature.

Connections and Implications:

• It is highly probable that the "Cooling and Heating Curve of 2 Objects for Primary School Science HTML5 Simulation" is a practical, interactive application of the principles behind Newton's Law of Cooling, adapted for a primary school level.
• Both resources emphasize the use of interactive simulations as a tool for science education.
• The shared authorship suggests a consistent pedagogical approach and a focus on providing high-quality, open-source educational materials in thermal physics and related areas.
• The mention of EJS as the compilation tool provides insight into the technical foundation of these interactive resources and connects them to a broader community of educators and developers using this toolkit.

In conclusion, these resources highlight the Open Educational Resources / Open Source Physics @ Singapore platform's commitment to providing interactive and accessible science learning tools. The "Cooling and Heating Curve" simulation offers a hands-on way for primary students to grasp basic concepts of heat transfer, while the mention of "Newton's Law of Cooling" indicates a deeper engagement with the underlying scientific principles, likely through another simulation or explanation built with the same collaborative and open-source ethos. The use of EJS as a development tool underscores the platform's technical approach to creating these educational resources.

Frequently Asked Questions

1. What is the primary focus of the "Cooling and Heating Curve of 2 Objects" simulation? This simulation, designed for primary school science, allows users to observe and understand how two different objects heat up or cool down over time. It visually demonstrates the concept of thermal energy transfer and how temperature changes occur.

2. Who developed the "Cooling and Heating Curve of 2 Objects" simulation? The simulation was developed by Shaun Quek, with contributions from Wolfgang Christian (Davidson College) and Sze Yee, under the Open Educational Resources / Open Source Physics @ Singapore initiative.

3. What are the intended learning goals for students using this simulation? While the specific learning goals aren't detailed in the provided text, it can be inferred that students are expected to learn about concepts such as heat transfer, temperature change, and the comparison of heating and cooling rates between different materials or under different conditions.

4. Is the "Cooling and Heating Curve of 2 Objects" simulation interactive? How can it be used? Yes, the inclusion of an embed link (<iframe...>) strongly suggests that the simulation is interactive and can be embedded into web pages. Users can likely manipulate variables within the simulation to observe the resulting heating and cooling curves of the two objects. The "For Teachers" section (text missing in the provided source) would likely provide specific guidance on its usage.

5. What other educational resources are associated with Open Source Physics @ Singapore? The provided text lists a wide variety of other interactive simulations and resources covering topics ranging from physics (mechanics, thermal physics, electromagnetism, waves, optics), chemistry (bonding, reactions, atomic structure), mathematics (geometry, algebra, games), and even some biology and computer science concepts. These resources are diverse and target various educational levels.

6. What is Easy JavaScript Simulations (EJS)? The text mentions that the "Cooling and Heating Curve" simulation and "Newton's Law of Cooling" were "Compiled with EJS 6.1 BETA." EJS is a free authoring and modeling tool written in Java that allows users to create interactive simulations and applets, primarily for science and mathematics education. It is also mentioned in the "Easy Java/JavaScript Simulations Toolkit" link provided.

7. How does the "Cooling and Heating Curve" simulation relate to Newton's Law of Cooling? While the "Cooling and Heating Curve" simulation is designed for primary school, it likely illustrates the principles behind Newton's Law of Cooling in a simplified manner. Newton's Law of Cooling (as indicated by the separate excerpt with the same authors) describes the rate of heat loss of a body being directly proportional to the difference in the temperatures between the body and its surroundings. The primary school simulation would likely show this principle in action without delving into the mathematical formulation.

8. Are these educational resources freely available? What are the licensing terms? The Open Educational Resources / Open Source Physics @ Singapore initiative suggests that these resources are intended to be freely accessible and usable for educational purposes. The text explicitly states that the contents are licensed under the Creative Commons Attribution-Share Alike 4.0 Singapore License, which allows for sharing and adaptation with proper attribution and under the same license terms.
