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.
In this activity, we will demonstrate the essence of mixing through an activity of blending a couple of colored dough balls. You will learn how blending these balls can be accomplished by simply following the fundamental actions of mixing processes: repeated stretching and folding.
Turning on the faucet, you receive water for washing your hands or taking a shower. How convenient! Modern technology allows for transporting water to your home from a reservoir far away from your home through pipes. Do you know how water is transported through pipe? Do you know how the geometries of the pipes affect the efficiency of water transport? In this activity, you will learn about the principle of pipe flow through a water gun activity. We will guide you to build a water gun with different gun lengths and experience the effect of gun lengths (or more specifically, pipe lengths) on shooting the water to the target.
Want to learn more about physics from the comfort of your own home? All you need is a ruler and your thinking cap! Watch Professor Kafle demonstrate this interesting phenomenon that seems like magic but is actually just physics. All you need to participate is a ruler with a smooth surface.
This activity is related to electrostatic force.
You will need: A water bottle, 2 straws and a paper towel.
This activity is related to the lift force.
You only need a piece of paper to try it!
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.
Ride along on a 30-minute journey from the Earth to the edges of the known universe, from the impossibly small to the unimaginably big, in a show that employs computer graphics and NASA images.
Nuclear radiation is a rampant threat around the world—one that many may not even be aware exists. Together with the MIT Media Lab, WPI researchers are working to create a way for citizens to take the threat of nuclear radiation into their own hands, protecting themselves and others from unknown radiological releases.
