Cool a sheet of metal and leave it in the room, if the air contains water vapour it will condense on the cold metal.
Yes, Olympus Mons is considered to be a "sleeping" volcano, meaning it is not currently active but may not be extinct. Studies of the volcano show no signs of recent eruptions, but its young geological features suggest that it could potentially erupt again in the future. Scientists continue to monitor it for any signs of activity.
A surge trigger point shows the level at which a surge in activity or demand will initiate a response or action. It helps identify the threshold at which an increase in activity will require attention or intervention.
Evidence for convection currents within Earth's mantle includes the movement of tectonic plates, which can be observed through the shifting of continents and seismic activity. Geophysical studies, such as seismic wave analysis, show variations in mantle density and temperature that suggest convective processes. Additionally, the distribution of volcanic activity and mid-ocean ridges indicates the upwelling of hot mantle material and the sinking of cooler material, supporting the existence of convection currents.
Mount Pelée, located in Martinique, is an active stratovolcano known for its catastrophic eruption in 1902. Future predictions suggest that it may continue to show volcanic activity, with experts monitoring for signs of unrest, such as seismic activity or gas emissions. While predicting specific eruptions is challenging, ongoing research aims to improve forecasting capabilities to mitigate risks for nearby populations. Continued vigilance and monitoring are essential for assessing potential future hazards associated with this volcano.
Watch dry ice turn into carbon dioxide gas without going through a liquid stage.
By the saliva in your mouth? Look at your breath on a cold day outside. Breathe on a mirror and watch it fog.
With an scaffolding activity to show the new words with their meaning, for example a matching activity. Of course that would be the first one but I suggest at least three activities.
One simple activity to demonstrate that air contains water vapor is to take a glass filled with ice cubes and observe the condensation forming on the outside. As the cold surface cools the air around it, the water vapor in the warm air condenses into tiny droplets, illustrating that air indeed contains moisture. This phenomenon occurs because cooler air holds less water vapor than warmer air, leading to visible condensation. Thus, the presence of water droplets on the glass provides clear evidence that air contains water vapor.
You could exhale onto a mirror. The moisture in your breathe condenses on the mirror to form the "fog" that you see. Be quick though because the condensations evaporates very quickly. You can get a similar effect by taking a very warm shower, with nowhere to escape, the steam condenses on the mirrors or tile i your bathroom, and makes it moist or "foggy".
Click "edit" on the activity then you can choose to hide or show it.
