Objectives are often obvious, but it is good to have a concrete goal in mind when you conduct an experiment. In this case, you want to demonstrate the concept of solubility. The term "solubility" refers to something's ability to dissolve completely in a liquid. Although a salt and sand experiment is generally pretty simple, you'll find you get more satisfaction by going through the paperwork. An experiment is nothing without a critical eye. Making a habit of note taking during experiments will enrich the experience. You'll notice things you might otherwise overlook. Even obvious things should be written down. That way, you'll be able to make sense of it later. Observe the basic movements and changes in the experiment. Make note of the following. Although the salt dissolves in the heated water, the salt remains intact. The salt needs the water to be heated before it dissolves. The salt doesn't boil away with the water. By discussing an experiment in a group, you'll be able to compare your observations. If this experiment is happening in a class setting, it's possible that one of the experiments will turn out differently than the others. While this is likely a result of error, it's still interesting to see a new result and figure out where it came from. If you're by yourself, checking out a recording of the experiment on a streaming site like YouTube can be interesting. Even if you know the result, it is nonetheless worthwhile to see how someone else went about it. Once you do the basic experiment, you should think of other questions you'd like to see answered. For example, how much longer does the process take if the portions are made unequal? Separating sand and salt is a very basic experiment, but the possibilities for a budding scientist are endless. For a lot of homebrewed experiments, baking soda is very fun to play around with. You could try adding that to your mixture next time. Doing this as part of a group is more enjoyable than doing it on your own.

Sun poisoning is a term used to describe severe sunburns and reactions to UV rays (photodermatitis). If your skin develops blisters, if the burn is very painful, or is accompanied by a fever and extreme thirst or fatigue, seek medical attention immediately. These may be signs of a more serious medical condition. There may be a genetic sensitivity that causes this. Additionally, metabolic causes can result from a lack of niacin or vitamin B3. The typical symptoms and treatment are described in this article, but the most severe symptoms that require medical attention include: Blisters you may experience itchiness and raised areas of your skin where you were excessively exposed to sunlight Rashes along with blisters or bumps, it is common to see rashes that may or may not be itchy. these rashes can resemble eczema Swelling there may be pain and redness in areas of excessive sunlight exposure Nausea, fever, headache, and chills These symptoms may arise as a result of a combination of photosensitivity and exposure to heat If you experience these symptoms, it is important to seek medical attention right away for further evaluation of the severity of your sunburn. The two most common forms of skin cancer basal cell carcinoma and squamous cell carcinoma are directly related to sun exposure. These cancers form primarily on the face, ears, and hands. A person's risk for melanoma the most serious form of skin cancer doubles if he has had five or more sunburns. More importantly, if you have a severe sunburn, you are at greater risk for melanoma. Heatstroke occurs when the body fails to regulate its own temperature, and body temperature continues to rise. Since sun exposure can lead to both extreme sunburns and heat stroke, many people who experience extreme sunburns also run a risk of heatstroke. The primary signs of heatstroke are: Hot, red, dry skin Rapid, strong pulse Extreme body temperatures Nausea or vomiting

You'll need to know exactly what's going into the dishes. Is there chicken broth in the stuffing? How about the gravy? And how do they feel about catering to your wishes? You know them best -- what would they respond to? Offer to make a compromise. You can either offer to host (taking the weight off their shoulders and the pressure to stay healthy off you), offer to help cook (that way you can influence what goes in the recipes or have portions set aside pre-meat stage), or offer to bring some side dishes. You'll definitely need to plan the menu together! Many vegetarians find that if they don't make a big deal of it, no one else will either. So if you're fine just using logic, reason, and a bit of coy prying ("Mmm, grandma, this looks so good! What's all in it?"), you may get through Thanksgiving without Uncle Bob waving bacon in your face. Consuming a bit of chicken stock once a year will not make the vegetarian gods take your gold star away. You know what your family will respond to. If Aunt Flo won't accommodate you when you say, "I have a disturbing documentary for you to watch on the terrors of the agricultural industry, Flo," don't waste your time. Instead, consider saying, "I'm trying to be as healthy as possible. Vegetarians live longer, have lower rates of heart disease and cancer, and you know about our history of high blood pressure." In other words, speak their language. If they see your reasoning, they may be more open to compromise. Know your pesky uncle is trying to make you smile. When you're subject to a surprising amount of Tofurkey jokes, don't be alarmed. Your awkward relatives are just trying to relate to you in any way they know how. That and, well, they may honestly just not get it. And that's fine. Smile anyway. Going into Thanksgiving and demanding your 94 year-old meat-and-potatoes grandma change up the Thanksgiving she's been cooking for over half a century and leaving her to the wolves is just cruel. Give her some tips! If she doesn't want you in the kitchen with her (or you bringing your own dishes), she may need some pointers. You know the drill. Mushroom gravy. Using olive oil instead of butter. Almond milk instead of dairy. Coconut oil in the sweet potatoes. Vegetable stock instead of chicken stock. Yadda, yadda, yadda ad infinitum. Ask for a portion to be put aside before meat or animal products get put in. That way everyone can be happy! And you're perfectly willing to join in the dividing and adding the mushroom gravy and veggie stock yourself, of course.

If you're dead set on consuming absolutely zero animal products, talk to your host. If you're willing to fudge a little, consider not mentioning it at all. Know your audience. Offer suggestions to your host.
