Liquid is the material state whose shape depends on the container; on the other hand, solid material has a specific shape that resists the external force-induced deformation. Most of the time, we can tell if the material is liquid or solid by examining its response to external force. However, can you think of a material that can be both liquid and solid at the same time depending on how you interact with the material? In this hands-on activity, we will guide you to make a material that is between liquid and solid. When you gently and slowly poke the material, it is fluid like water but when you poke it hard and fast, it is elastic like a solid material. This material is categorized as a non-Newtonian fluid. In this activity, you will learn how non-Newtonian fluid behaves differently from conventional Newtonian fluid.
Large oil spills have been a common environmental problem for decades affecting wildlife, beaches and water sources. Environmental engineers have come up with many creative solutions to clean up these spills. WPI Engineering Ambassadors will tell you about some of these solutions and then you can try to clean up your own oil spill at home
In this activity, elementary students will learn how to make lenses out of water droplets to magnify words and images! This module will provide a gentle and fun introduction to the basics of optics and their applications.
Would you like to be a treasure hunter? In this game, you will find the right combination of numbers to unlock treasure chests! As you play the game, you will visit the penny plains, wealthy wonderland, big bucks beach, fortune forest, diamond desert, cash canyon, and profit plateau. As you will move through worlds, you will open bigger treasure chests and earn more golds.
Have you ever looked at a complicated math problem and asked yourself, “Where do I start?” The goal of our project is to see how websites should show online math problems in ways that are easy to understand for students. With your help, we can get closer to answering this question.
From Here to There is an interactive touch-based application that allows students to dynamically interact with numbers and expressions. Rather than solving a problem by hand and typing in the answer, students can transform expressions or equations by dragging or breaking apart the number. These activities provide access to the rewarding and playful challenges of algebra and equation solving.
At National Grid, safety is in our DNA. To help promote electric safety, we created a seven-minute version of our electric live line safety demonstration. How much do you know about electricity safety?
