Teaching modern physics in high school is of increasingly importance as it can offer students a more realistic and updated vision of the world, and can provide an opportunity to understand the most recent scientific discoveries. In this context, general relativity (GR) occupies a prominent place, since it is related to astonishing scientific results, such as the first image of a black hole or the discovery of gravitational waves. In this paper we describe an educational proposal aimed at teaching GR in high schools in a fun and playful way using the so-called rubber sheet analogy. We present a set of instructions to build a simple and low-cost space-time simulator, and a series of related educational cards that guide the teacher in the implementation of the activities step by step. This work is the result of a long and productive debate among Italian high school teachers who have collaborated for many years with the Department of Mathematics and Physics of Roma Tre University in Rome. As our proposal relies on the collaboration with the final users, we believe that it will meet their needs and expectations, and it will help to treat GR in high school more and more over time.

在高中教授现代物理越来越重要，因为它可以为学生提供更现实和更新的世界视野，并且可以为了解最新的科学发现提供机会。在这种情况下，广义相对论（GR）占据着突出的位置，因为它与令人惊讶的科学结果有关，例如黑洞的第一张图像或引力波的发现。在本文中，我们描述了一种教育建议，旨在利用所谓的橡胶板类比，以有趣和有趣的方式在高中教授GR。我们提供了一组指令，以构建一个简单且低成本的时空模拟器，以及一系列相关的教育卡，这些卡可以逐步指导教师实施活动。这项工作是意大利高中教师与罗马罗马特雷大学的数学和物理系多年合作的长期成果辩论的结果。由于我们的提案依赖于与最终用户的合作，因此我们相信它将满足他们的需求和期望，并且随着时间的推移，它将有助于越来越多地在高中阶段对待GR。
