Investigate the Greenhouse EffectHas the temperature in your house felt hotter or colder recently? This could be due to the greenhouse effect. The greenhouse effect states that gases in the atmosphere, such as CO2, might increase the surface temperature of Earth. In this science fair project, you will build a small model of Earth and use it to see how the temperature varies, compared to outside of the model. If you select this science fair project, you will be a part of the effort that is working to figure out what role greenhouse gases have in shaping our Earth's atmosphereElhamSorting out SedimentationSedimentary rock forms in layers that are deposited one after the other over long periods of time. Oftentimes, sedimentary rock contains fossils and other debris that are deposited within the layers. How do sediments form? How are sediments of different shapes, sizes, and types sorted during the process of sedimentation? Find out in this science fair project!Hajar +JoudIs Smiling Contagious?*You've probably observed from your own personal experiences that some actions are contagious. Yawning is a great example. When one person in a room yawns, several other people usually do, too. Coughing, clearing your throat, these are other actions that often seem contagious. But what about smiling? Have you ever walked down the street and had a random stranger smile at you? Did it make you happy? Did you smile back? In this science fair project, you'll investigate whether smiling is contagious. You'll need to think of a way to design your experiment. One option would be to take a walk around a park and keep track of how many people smile at you, and whether those numbers change based on whether you smile at them or not. Or maybe you want to see if smiling has a chain reaction by having a friend walk a little ways behind you and see if the number of smiles he or she receives changes depending on whether you smile at the passersby first. However you design your experiment, make sure you're observing many people so that you can draw accurate conclusions.Loujain + RanaEnergy From Garbage(energy recycling)Questions:Can you produce a gas from decaying garbage?Can you control the amount of gas produced from decaying garbage?Dareen + SarahDo Plants Need Water?Plants need sunlight, nutrient rich soil and water to grow. Though the quality of the water has an effect on the plant’s health, there are many plants that are able to grow even when they are given water that is polluted or that has some salt content. Most plants are unable to grow out of water that is as salty as the ocean, though there are a few varieties that can. Water is not always in abundant supply, and when it comes down to making sure that people have enough to drink, sometimes plants are asked to go without. Farmers have turned to using brackish water, or water that has a low salt content, for their crops. Understanding what types of fluids plants can use can help scientists learn more about how to meet the needs of plants as well as people in times of draughtReem + FinaTo Clean Or Not To CleanDid you ever wonder if your ready-to-eat packaged lettuce is really free from bacteria? Does the brand of packaged lettuce really matter? Or if bacteria are present, how can you wash the lettuce to get ride of bacteria? Jane Alejandro really wanted to know those answers.SalmaFresh Food vs. Frozen FoodObjectiveThis project explores the differences between fresh and frozen foods.The goals of this project are:To study the differences between various fresh and frozen food samples.To encourage the development of new and improved food products.Freezing is a handy way of preserving many different kinds of food products. Food decomposes much more slowly when frozen. Yet, most of us are easily able to tell the difference between a fresh food item and its frozen alternative. Here we explore these differences, with a comparative study of fresh-versus-frozen foods. ................
