Students learn how water is used to generate electricity. They investigate water's potential-to-kinetic energy transformation in hands-on activities about falling water and waterwheels. During the activities, they take measurements, calculate averages and graph results.
3 sie 2021 · The free STEM lessons and activities below help students model and explore the water cycle, the various processes, the role landforms and water bodies play, and questions related to sustainability and the importance of water conservation.
5 paź 2023 · What can the act of balancing liquid on the surface of a coin tell us about the water molecules and molecular formulas? In this activity, students observe different types of intermolecular forces of water through two simple experiments.
In this fun activity, you will find out more about the properties of liquids by stacking them on top of each other.
11 paź 2023 · Figure \(\PageIndex{1}\) shows the phase diagram for water. Using the graph, if you know the pressure and temperature, you can determine the phase of water. The solid curves—boundaries between phases—indicate phase transitions, that is, temperatures and pressures at which the phases coexist.
evaporation: The process whereby atoms or molecules in a liquid state (such as water) gain sufficient energy to enter the gaseous state (such as water vapor). food chain: A sequence of organisms, each of which uses the next, lower member of the sequence as a food source.
If we want to determine the amount of energy change that occurs in the fluid as it passes between two points along a pipe per time, we need to multiply the energy change per volume by the volume of fluid passing through the pipe and divide by the time. But volume divided by time is just the current.
