There are ideas for learning centers and literacy bags. Get wet, get dry, go with the flow…
Down Comes the Rain
I love to read the book, Down Comes the Rain to the children as we begin this exciting unit on water, rain and wetness. It easily leads into a discussion of what we know about rain as well as what we want to learn. Writing down this information on Chart Tablet as we discuss helps the children to learn how to spell, read and take notes. Later, as our unit on rain progresses, we review the chart and see which questions we are then able to answer.
Thunder Cake is a story about a little girl who is scared of the rain and thunder. Her grandmother keeps her busy collecting things all around the farm. The cake is ready just as the rain starts to come down and the little girl realizes that she was too busy to be scared.
Here is a math center activity to do after reading Grandma’s Thunder Cake by Patricia Polacco. Use light blue felt for math mats and and Clear Flat Floral Marbles for the raindrop counters. Note: It is best to use the flat marbles so that they stay on the felt math mats rather than rolling onto the floor the way that regular marbles would. Also, the flat clear marbles look more like raindrops.
1. The teacher claps her hands to indicate thunder.
2. The children listen for the number of thunder claps and place that number of raindrops in the sky.
Rain water conservation
We all know the importance of water for all living beings and it is also necessary for farming and gardening. There are so many good water which are lost as we are not able to collect it and save it for future purpose. There are many ways by which we can save the precious rain water that we will be discussing in this article. But the easiest and also the cheapest method that every one can do is to use a rain barrel. Those who have garden can use the water collected in rain barrel for giving water to their garden. You can buy a best quality rain barrel that is also economical but save lots of water.
Evidence of water treatment has been found in ancient Greek and Sanskrit writings dating back to 2000 BC when boiling and physical filtration were the only methods known. if you are reliant on collected rainwater and are not connected to a towns water supply, then the water collected will be especially important to you. The amount of water you save with one of these systems is lower than the 50% savings that you can potentially get with a greywater recycling system because rainwater supply is less certain. “You will need to be able to rely on your mains water system as a backup during periods where there is little rainfall”, says Derek Hunt, from Rainharvesting Systems. The idea behind the process is simple. At the time, water was only treated so it would taste better.
If you are from the city, then it is possible to replace all or at least a substantial portion of your fresh water requirements by the capture and storage of rainwater from your roof. However, unlike a greywater recycling system, RHS requires little specialist maintenance and the rainwater you harvest – as it has never been used to wash food or the human body – is likely to contain far less bacteria and contaminants than greywater. Rainwater is collected when it falls on the earth, stored and utilized at a later point. Water safety did not become a concern until the 1670s when the invention of the microscope equipped scientists to view microorganisms in supposedly ‘clean’ water. Being largely self sufficient in water supply is possible for a vast majority of Australian households and buildings.
Most homeowners can install and use a rainwater harvesting system for landscape irrigation without public health and water rights concerns. It can be purified to make it into drinking water, used for daily applications and even utilized in large scale industries. In the most basic form of this technology, rainwater is collected in simple vessels at the edge of the roof. All rainwater harvesting systems operate using typical roof drainage layouts. For larger-scale commercial projects, it is a good idea to check with the local OSE Water Rights Division to make sure the project does not inappropriately affect rainwater runoff into a stream system, therefore impacting a public water supply.
In short, Rainwater harvesting is a process or technique of collecting, filtering, storing and using rainwater for irrigation and for various other purposes. Variations on this basic approach include collection of rainwater in gutters which drain to the collection vessel through down-pipes constructed for this purpose, and/or the diversion of rainwater from the gutters to containers for settling particulates before being conveyed to the storage container for the domestic use. This means rainwater runs down the roof and into the guttering and down pipes in the normal way before passing through a filter, which removes the leaves and debris. Also, contact the local New Mexico Environment Department regarding any potential public health concerns. To reduce the consumption of groundwater, many people around the world are using rainwater harvesting systems.
As the rooftop is the main catchment area, the amount and quality of rainwater collected depends on the area and type of roofing material. The rainwater is then stored in an underground tank containing a pump and filter. Please see Policy Development for the official policy on rainwater harvesting. Water has been harvested in India since antiquity, with our ancestors perfecting the art of water management. The water can be used, with or without the addition of a header tank, for a variety of non-potable uses including flushing toilets, washing vehicles, gardening and washing clothes. This is a look at some of the traditional schemes of water harvesting, dying wisdoms, which are slowly being lost to the modern onslaught. To address the challenges of water security in the new millenium, a mixture of traditional wisdom and new techniques must be employed. See some of the modern systems that are being used in India’s cities, systems which merely build upon the lore of the past.

A wood gas stove differs from a wood burning stove. First, a wood gas stove uses gas from wood, and not the wood, as fuel. Second, a wood gas stove is common in camping sites and not in homes with chimneys. Third, because of its use in camping, a wood gas stove is small and portable. Lastly, the technology that turns wood into gas seems fairly new in the world of biotechnology, unlike wood burning, which has been a traditional way of creating fire for cooking, heating, and light.
A wood gas stove uses biomass gasification to turn low burning emissions as fuel. Unlike in wood burning, where more wood is added to build a hotter blaze, a wood gas emission requires only a low burning blaze, which lasts longer. The fuel, such as wood chips or shavings, measures lesser in size and number than the usual logs for burning. In fact, partially burnt wood chips turn into charcoal, which remains highly usable as fuel in a stove.
A wood gas stove commonly uses the downdraft principle. This principle involves an inverted cylinder that houses the low burning wood chips. Gas escapes downwards through holes at the bottom and climbs upwards through the space between the two cylinders. Additional air oxidizes the carbon monoxide and makes it ripe for burning. The carbon monoxide from inside the closed cylinder burns when it reaches the top where an igniter produces a spark.
Similar to any other gas stove, the wood gas stove produces no smoke. However, unlike normal gas stoves, it does not leak gas, but uses it up while burning. When all the wood chips, shavings, sawdust, and other wood products have burned up, all that remains is fine ash without charred bits. This process obviously uses every piece of fuel with little to no carbon emissions produced. A large stove may need blocks of wood or sticks, but the length of use extends to several more cook-offs before all fuel has burned out.
Based on the brief explanation of the gasification process, the wood gas stove clearly brings a safer and more economical alternative to cooking equipment. Wood by-products, such as wood pellets that sell about three dollars for each forty-pound bag, seem cheaper than paying the gas company every month. Commercial gas from pipes or from gas tanks also present the risk of leaks, which often lead to gas explosions.
Furthermore, a wood burning stove in the house could be toxic to residents. The location of the stove determines the effects of different atmospheric pressures at different areas in the house. A stove in the basement increases the risk of a downdraft, which releases carbon monoxide back into the house because of the stack effect. The carbon monoxide poisons the people while they are sleeping, or lead to explosions when the gas comes into contact to a burning flame, or even a lighted cigarette.
Aside from cooking, a giant fireplace that uses the same principle as the wood gas stove can produce heat and light when needed. An innovative architect can design a fireplace that produces fire using the downdraft principle. The middle of the living room seems a perfect place to build it. Because it is smokeless, the fireplace produces only light and heat, which a flue catches and distributes throughout the house.
