What are the 10 steps of the rock cycle? Metamorphic rocks underground melt to become magma. When a volcano erupts, magma flows out of it. (When magma is on the earth’s surface, it is called lava.)…When the particles are carried somewhere else, it is called erosion. Transportation. Deposition. Compaction & Cementation. What is the rock […]
How do I introduce my students Heat?
How do I introduce my students Heat? 2 Introduction of New Material Before having groups start their videos ask students to provide examples of when they have experienced heat transfer in the real world. Ask them to think deeper about examples that have more than one form of heat transfer. Encourage debate about the most […]

Why do we see rainbow colors in oil or bubbles?
Why do we see rainbow colors in oil or bubbles? Why do rainbow-like colors appear on the surface of oil? The wavelength corresponding to the constructive interference also differs and this causes the reflected light to have various colours. As a result, a rainbow-like colour pattern is shown on the oil surface and this phenomenon […]
Why atleast one open heater is used?
Why atleast one open heater is used? Why at least one open heater is used? Explanation: The open heater works as a deaerator. Are open or closed feedwater heaters more efficient? Heat transfer in closed feedwater heaters is less effective since the two streams are not allowed to be in direct contact. Most steam power […]

How does an LDR change resistance?
How does an LDR change resistance? The LDR. LDRs (light-dependent resistors) are used to detect light levels, eg in automatic security lights. Their resistance decreases as the light intensity increases. In the dark and at low light levels, the resistance of an LDR is high, and little current can flow through it. Why does the […]
