Life in America in the 1800s essays
Life in America in the 1800's essays In America, the country was beginning to grow. People came from all sides. Ships came from Sweden, England, and other countries. People already there, slowly began to travel west. Some traveled by wagon, some boarded steamboats, some traveled by foot, and if there were railroads where they were going, they sometimes took a train. And when they got there, no houses were sitting already made, waiting for them to buy. They had to build them. Some made their houses out of sod, and some cut down trees and built houses. And those who choose to live in the woods usually had to clear a space. Some big stumps took a day or more to root up. In the spring the settlers would plant there crops and tap maple trees. When the settlers planted corn, they put six corn kernels in each hole, because they knew some would not sprout. After the tapped the maple trees, they would boil it down into syrup. Sometimes they would take spoonfuls of hot syrup and drop it onto the snow, and it hardened into candy. In the summer settlers tended their crops, and watched their livestock grow. Families couldnt spare much time away from the fields, so picnics and/or barn raisings were a rare treat. Near the end of the summer, they would harvest hay. The whole family bring in the hay would feed their livestock till summer came again. Harvesting hay was done in the hottest weather so the hay was dry for storing. During the fall, Crops were harvested. Apples and beechnuts were also harvested. When the apples were harvested, women carefully packed and stored the best apples to eat in the winter. The rest were made into cider, vinegar, applesauce or apple butter. Or they were cut into apple rings and dried. The settlers also butchered hogs and/or a head or two of cattle. They cleaned out the carcasses, then salted or smoked the meat to preserve it. As the year rolled on into winter, the settlers were able to ...

How to Build a Baking Soda Volcano Science Fair Project
How to Build a Baking Soda Volcano Science Fair Project The baking soda and vinegar volcano is the kitchen equivalent of a volcano. Obviously, its notà the realà thing, but its cool all the same! The baking soda volcano is also non-toxic, which adds to its appeal. It is a classic science project which can help kids learn about chemical reactions and what happens when a volcano erupts. This project takes about 30 minutes to complete. Did You Know? The cool red lava is the result of a chemical reaction between the baking soda and vinegar.In this reaction, carbon dioxide gas is produced, which is also present in real volcanoes.As the carbon dioxide gas is produced, pressure builds up inside the plastic bottle, until the gas bubbles (thanks to the detergent) out of the volcano. Volcano Science Project Materials 6 cups flour2 cups salt4 tablespoons cooking oilwarm waterplastic soda bottledishwashing detergentfood coloringvinegarbaking dish or another pan2 T baking soda Make the Chemical Volcano First, make the cone of the baking soda volcano. Mix 6 cups flour, 2 cups salt, 4 tablespoons cooking oil, and 2 cups of water. The resulting mixture should be smooth and firm (more water may be added if needed).Stand the soda bottle in the baking pan and mold the dough around it into a volcano shape. Dont cover the hole or drop dough into it.Fill the bottle most of the way full with warm water and a bit of red food color (can be done before sculpting if you dont take so long that the water gets cold).Add 6 drops of detergent to the bottle contents. The detergent helps trap the bubbles produced by the reaction so you get better lava.Add 2 tablespoons baking soda to the liquid.Slowly pour vinegar into the bottle. Watch out - eruption time! Experiment with the Volcano While its fine for a young investigator to explore a simple model volcano, youll want to add the scientific method if you want to make the volcano a better science project. Here are ideas for ways to experiment with a baking soda volcano: Make a prediction about what happens if you change the amount of baking soda or vinegar. Record and analyze the effect, if any.Can you think of ways to change the volcano to make the eruption go higher or last longer? This might involve changing the chemicals or the shape of the volcano. It helps to record numerical data, such as the volume of liquid, the height of the lava, or duration of the eruption.Does it affect your volcano if you use a different kind of chemical to color the volcano? You could use tempera paint powder. Try using tonic water instead of regular water to get a volcano that glows under black light.What happens if you substitute other acids instead of vinegar or other bases instead of baking soda? Examples of acids include lemon juice or ketchup. Examples of bases include laundry detergent and household ammonia. Use caution if you substitute chemicals because some mixtures can be dangerous and produce hazardous gasses. Dont experiment with bleach or bathroom cleane rs. Adding a bit of food coloring will result in red-orange lava! Orange seems to work the best. Add some red, yellow, and even purple, for a bright display.
