Upon getting information about an upcoming school science fair and the need to consider a topic of interest, many students will typically have no idea where to get started. While the science fair is typically a common occurrence in any school at any grade level, there are different types of topics that should be taken a look at depending on the age of the student. After first taking a look at the many different categories of science projects, you will be able to locate a suitable choice of topic to take to the next level.There is a wide variety of categories that fall under the types of science projects that can be chosen for a school science fair. These include biology, chemistry, physics, microbiology, biochemistry, medicine, environmental, mathematics, engineering, and earth science. While you may not have yet learned very much in any of these categories, don’t be afraid to see what each one entails. Taking a good look at your interests will allow you to focus on the right direction to take.Many resources are also available for those who are unsure as to the topic they are wanting to use to create their science projects. If you take a look at the topics that fall under the biology category, you will likely notice that there are topics that deal with plants, animals, and humans. For those who are in 2nd grade or 3rd grade, an interesting topic may be to determine if ants are picky over what type of food they eat. While this topic might not be of interest to an 8th grader, it is certainly something in the biology category that an elementary school student would enjoy.Along with the biology category, a high school student may want to take a look at diffusion and osmosis in animal cells as this would be a more appropriate topic for the grade level. A student in 6th grade would be more advanced than an elementary school student, but not as advanced as a high school student. At this middle school grade level, a topic of how pH levels effect the lifespan of a tadpole may be of interest.Whichever resource is used to locate a topic for science projects, it is always a good idea to consider the grade level of the student prior to making a selection. It is always assumed to be best to have a project at an appropriate level in order to keep the attention of the student and provide a fun and enjoyable learning experience.

Pfizer Rallies After Announcing A Huge Price Hike For Its COVID-19 Vaccines
S&P 500 is currently trying to settle above 3730 as traders’ appetite for risk is growing. The U.S. dollar has recently gained strong downside momentum as the BoJ intervened to stop the rally in USD/JPY. Weaker U.S. dollar is bullish for stocks as it increases profits of multinational companies and makes U.S. equities cheaper for foreign investors.
The leading oil services company Schlumberger is up by 9% after beating analyst estimates on both earnings and revenue. Schlumberger’s peers Baker Hughes and Halliburton have also enjoyed strong support today.
Vaccine makers Pfizer and Moderna gained strong upside momentum after Pfizer announced that it will raise the price of its coronavirus vaccine to $110 – $130 per shot.
Biggest losers today include Verizon and Twitter. Verizon is down by 5% despite beating analyst estimates on both earnings and revenue. Subscriber numbers missed estimates, and traders pushed the stock to multi-year lows.
Twitter stock moved towards the $50 level as the U.S. may conduct a security review of Musk’s purchase of the company.
From a big picture point of view, today’s rebound is broad, and most market segments are moving higher. Treasury yields have started to move lower after testing new highs, providing additional support to S&P 500. It looks that some traders are ready to bet that Fed will be less hawkish than previously expected.
S&P 500 Tests Resistance At 3730
S&P 500 has recently managed to get above the 20 EMA and is trying to settle above the resistance at 3730. RSI is in the moderate territory, and there is plenty of room to gain additional upside momentum in case the right catalysts emerge.
If S&P 500 manages to settle above 3730, it will head towards the next resistance level at 3760. A successful test of this level will push S&P 500 towards the next resistance at October highs at 3805. The 50 EMA is located in the nearby, so S&P 500 will likely face strong resistance above the 3800 level.
On the support side, the previous resistance at 3700 will likely serve as the first support level for S&P 500. In case S&P 500 declines below this level, it will move towards the next support level at 3675. A move below 3675 will push S&P 500 towards the support at 3640.
Can Nutrition Bars Really Be Nutritional?
My patients frequently ask me if using nutrition bars would be of any benefit to their overall health or weight loss plan. I admit, even I grab one of these bars every now and then for a quick snack, or even lunch on a really busy day sometimes. In fact, I would much rather have my patients substitute a good nutrition bar for lunch than grab a high-saturated-fat burger and fries.These bars are convenient, they don’t require refrigeration, and, if you read labels before buying, they really can help you get some good nutrition in a hurry. Here’s what I tell my patients about the pros and cons of the “nutrition on the run” that these bars offer.Are All Nutrition Bars Alike?Seems every time I go to the health food store, there’s a new nutrition bar promising to be better tasting, or more vitamin/protein-packed than all the other bars! However, what tastes good to me may not to you, so, different flavors aside, let me explain what ingredients should be in a good nutrition bar.•Protein:For meal replacement, a good bar should have at least 15 grams of protein, preferably from whey or even casein protein and not soy, gelatin or collagen protein. Many bars, however, contain soy protein isolate, or a blend of whey, casein, and soy. Soy products can interfere with thyroid hormones as well as imbalance male and female hormones, as it adds plant estrogen, or phytoestrogens, to your body.•Fat: Should be fairly low in fat, not more than 3 grams saturated fat and 0 trans fat, 10 grams total fat. Steer clear of bars that contain cholesterol-boosting oils like palm kernel oil. Bars with polyunsaturated vegetable oils like olive, safflower, or coconut oil are best.•Carbohydrate: For meal replacement, there should be a balanced fat/carbohydrate/protein ratio, in a 40/30/30 distribution, i.e., 30% protein, 30% fat, 40% carbohydrate. If you want added protein only, then the carb and fat level can be lower than this distribution. Some bars can contain a whopping amount of sugar, however! Limit sugar to 10-15 grams.•Sugar Alcohols: Many low carb nutrition bars contain sugar alcohols. These help sweeten the bar without adding carbohydrates. When figuring the carbohydrate, or glycemic load, they should be subtracted from the overall carbohydrate content. For example, if the bar contains 25 grams of carbohydrate and also 20 grams of sugar alcohols, then the effective carbohydrate count would only be 5. Some people get digestive upsets from sugar alcohols which can be a drawback to bars that contain it.•Vitamins: A good bar has at least 1/3 of the minimum daily requirements for vitamins, usually in the 30% range for crucial vitamins like C, E, D, A. This is especially important if you are using a nutrition bar as a meal replacement.•Minerals: Many good bars also contain 1/3 the minimum daily requirement of necessary minerals like potassium, magnesium, calcium, zinc. Again, should be in the 30% range for meal replacement use.•Fiber: Many nutrition bars contain very little fiber, but several brands have between 4-6 grams. Or, at least have a piece of fruit, or a salad, with it to make up for fiber deficiencies.•Calories: If you’re using it as a meal replacement for a quick lunch, your nutrition bar should have between 200-300 calories in it. Otherwise you’ll be at the snack machine in an hour!Are There Any Cons to Nutrition Bars?We’ve talked about what I recommend a good bar should contain. Now, are there any real disadvantages, or cons, to using nutrition bars? As I tell my patients, I think that answer depends on how you use them. With that in mind, here are some possible disadvantages to using nutrition bars that you might consider when deciding to use them everyday or just occasionally:•Cost: Most good nutrition bars can cost anywhere from $2 to $3 a piece. This can get expensive if you use them everyday. However, if you use them as a meal replacement for one meal a day, that’s still less than the cheapest burger place for lunch, a lot less fat and salt, controlled calorie amount, and more vitamins and minerals.•Excessive Nutrition: If you’re using a nutrition bar for just a snack here and there, and not as meal replacement, look for one that has less than the 30% minimum daily requirement of vitamins and minerals to avoid over-intake of nutrients. This is especially true if you are taking a good vitamin/mineral supplement already everyday and eating well at your other meals. Too much Vitamin A can pose liver problems. Too much Vitamin E can result in excessive bleeding should you cut yourself.•May Contain Herbals: Steer clear of nutrition bars that contain “energy boosting” herbs such as ephedra, bitter orange, or even caffeine from green or black tea extracts which can affect some people’s heart rate or blood pressure adversely.•Taste: The taste of these bars can vary widely from brand to brand and price range. Some are in the “acquired” taste category and can be rather dry. Then there are others that really taste great. You really have to shop around and try a lot of different ones to find one you like and could eat on a regular basis.If you take medications, it’s always a good idea to ask your doctor about adding anything with vitamins/minerals in it that may interfere with absorption of your medications. Nutrition bars should not take the place of a balanced diet of whole foods, but they can provide a satisfying solution to a chocolaty-sweets craving, or provide a quick and nutritional meal on the run!
