The water level will decrease as it is exposed to the heat of the sun. Back when I was teaching we had a whole song about the water cycle. Kids can use the recycled materials projects as a science science experiment to explore how evaporation works with different sized containers. She hypothesized that of the four containers that were the same size, the open container would evaporate first and the covered container would evaporate last. You will see that the water in the bowl placed in direct sunlight evaporates much more quickly than the shaded water due to the higher levels of heat, which increase molecular activity in the water, thus expediting evaporation. Recognise that evaporation occurs in different liquids, not just water. There are several ways you can do this: by using an eye dropper, small spoon (like a teaspoon), or the end of a straw. % Evaporation is the name of the game in this session as children use it to separate materials in solutions.

While we made good hypotheses with this experiment, we ran into a bit of bad weather luck following our outdoor science. Our Mister 7 loves learning about scientific principles, and we found that his knowledge of states of matter was quite good when we started talking about adding heat as a form of energy to help the molecules break apart and turn from liquid to gas. Evaporation is the process in which a liquid is converted to a vapour. We talked about water evaporation while engineering a few different water containers and working in a bit of math, too. Place the tray outside in a beam of direct sunlight. Early in the day, soak two identical t-shirts in water and drape each shirt over a chair in separate corners of the room. Ask if their hands feel cooler now they are wet. Where, then, does the water go when it leaves the towel? 4c2: observe that some materials change state when they are heated or cooled, and measure or research the temperature at which this happens in degrees Celsius (C) 4c3: identify the part played by evaporation and condensation in the water cycle . Wet two identical pieces of cloth and wring the excess water out. You will see that the water is gone, and that the salt remains on the black paper. Evaporation is when a liquid vaporises. Learn about natural cooling and heating processes that are caused by changing states of matter! Clark then stirred the mixture until the salt dissolved. This differentiated science lesson focuses on the relationship between the rate of evaporation and heat. Place the watch glass (glass plate) on top of the beaker.

Return to the experiment every hour for the rest of the day, continuing to make observations and illustrations of the water levels. Disappearing water Place a drop of water on the ground in a sunny place and watch it disappear. Our first experiment was to look at how evaporation would separate saltwater. Making educational experiences better for everyone. Precipitation is when so much water condenses that the clouds get heavy, and water falls back to earth as rain ( or snow ). Walk around the class, listening to their ideas. Applications. the jars, noting the current water levels. The water disappeared due to the process of evaporation, but the salt stayed because it would require a lot more energy than provided by the sunlight to fully evaporate. A few weeks ago, when we had a brief hot spell, we added water to some sand and left it outside to see what would happen. Our sunny day turned into several days of rain and gloomy skies. Evaporation is when a liquid changes into a gas. We talked about how the evaporation left behind the salt and how this happens in the oceans, too. Then, take the jars outside and place them both in an equally sunny spot. You will observe that the water in the uncovered jar disappears more every day, while the water in the covered jar evaporates at a much slower rate because the evaporation process gets blocked by the aluminum foil. Does water have to be a certain temperature to evaporate salt? Im sure that was quicker, but it would have been more restrictive and I really want Clark to be doing the work, not me! Leaving one of the jars uncovered, cover the other one with an improvised aluminum foil lid. Evaporation happens when a liquid turns into a gas. 2010-2023 The OT Toolbox | Privacy Policy, When Executive Function Skills Impair Handwriting, Executive Functioning Skills- Teach Planning and Prioritization, Fine Motor Activities to Improve Open Thumb Web Space, Activities to improve smooth visual pursuits, Classroom Accommodations for Visual Impairments.
