Third Grade Science Lesson Plans

blogger /

In the third grade, science and social studies go hand-in-hand in raising students environmental and social awareness. Lessons about the environment, health and animals are surefire hits with kids, and Studies Weekly takes full advantage of this. Third graders will enjoy the way the write-ups tap into their curiosity, and with curiosity comes interest, and an interest in the subject matter paves the way for straight As.

The Environment

As the caretakers of nature, human beings are tasked to safeguard the environment from peril. But of course, before anyone can take any protective measure, one must know what comprises nature. And students will get more than enough information just by reading through our magazines. Topics like forests, the atmosphere, mountains and other terrain are discussed thoroughly. Beyond high test scores, third graders will have an increased appreciation for nature, and will perhaps lead them to nurture their surroundings.

Plants and Planting Seedlings

Plants are constituents of a very important natural cycle called photosynthesis. During this period, oxygen is produced, in which nearly every living thing on the planet benefits from. Given the importance of plants, third graders are treated to very informative discussions on trees and shrubs, and how they affect life on the planet.

To further the learning from the discussion, kids are asked to plant a tree or any seedling. They are to take care of the plant, giving it water and placing it in an area wherein it receives ample sunlight.

Magnetism

Also taken up in the previous school year, the concept of magnetism makes a roaring comeback in K-3 science. Apart from the detailed explanations provided by Studies Weekly, students will perform simple experiments on how metals are attracted to magnets and why magnets repel one another. This topic may be a bit more complex than others, but our magazines are designed to break down the hardest parts.

Animals

The animal kingdom is a diverse realm filled with interesting creatures. Third-graders will be immersed in the general classifications of animals, such as mammals, birds, reptiles and many more. Vertebrates and invertebrates are also classified and well-explained. Even with the sheer amount of information that this topic carries, a lot of kids ace lessons animals, given their interest on the subject. Studies Weekly increases the likelihood of getting good grades even further.

Astronomy

If theres anything nearly as interesting as animals, its probably outer space. A lot of kids dream to be astronauts, and this topic gives them a sneak peek on their desired profession. Discussions on the solar system, stars, comets and other stellar bodies take center stage, as most third graders relish every bit of information about them.

Solar Energy

Sunlight is an important component for life on earth. It is also a primary source of heat for plants, animals and some technological creations. They will learn why the temperatures of some materials and colors are higher than others, once exposed to a lot of sunlight, or heat for that matter. Also, the effects of solar energy to the environment and human life will be taken up.

The Science Of Skin Rejuvenation

blogger /

Skin rejuvenation can be confusing to even the most informed patients, and understanding how directed and combination therapies act to deliver results, is crucial. In general, the degree of effect is directly related to the depth of penetration in the skin. Skin can be divided into three layers, the epidermis, constituting the outer layer, and the dermis, the inner two layers. Therapies are classified as superficial, medium, or deep based on their depth of penetration. The three most common treatment modalities used for skin rejuvenation are chemical peels, mechanical dermabrasion, and lasers. All three modalities can be used for superficial, medium, or deep rejuvenation.

Medical grade skin care products act to hydrate skin, increase exfoliation, build collagen, and treat skin discolorations and blemishes. Topical vitamin therapy is a common, minimally invasive therapy, of which, the most relevant to skin rejuvenation is tretinoin, a vitamin A derivative. It acts to rejuvenate, by thickening the epidermis and decreasing photoaging, including: dyschromias and brown spots, in the short term and increasing collagen production with a decrease in fine wrinkles with longer courses. Hydroquinone and Kojic acid are topical bleaching agents that inhibit melanin production: lightening age spots, imporoving melasma, as well as other causes of hyperpigmented blemishes.

Superficial rejuvenation primarily includes glycolic acid and jessner chemical peels and acts on the epidermis, decreasing discolorations and blemishes while allowing the germinal layer of the epidermis to regenerate. Additionally, they also act to increase superficial collagen formation in the dermis, improving fine wrinkles. Lasers can be used to perform “micropeels,” acting on the epidermis only, with benefits similar to the other superficial rejuvenation procedures.

Medium or deep rejuvenations act to the level of the dermis and are used to treat deeper photoaging and wrinkles. By increasing the depth of penetration, the overall effect is increased due to improved recruiting of fibroblast activity and collagen deposition. Consequently, there is also an increased risk of complications with deeper rejuvenations, which can include hypopigmentation and scarring, along with prolonged healing times. Medium and deep chemical peels include jessner/TCA peels and phenol peels, respectively. Dermabrasion is an effective resurfacing technique that uses mechanical abrasion to remove skin, layer by layer. Today, it is largely used for scar resurfacing/revision and the treatment of well formed wrinkles around the mouth. The depth of treatment with conventional lasers is primarily controlled by the type of laser used, the power settings, and the number of passes performed. In general, less aggressive settings and a decreased number of passes, result in less down time, a more superficial treatment, and subsequently less impressive results. In addition to the superficial rejuvenation benefits, the deeper rejuvenation procedures improve photoaging in the dermis along with deeper, more robust collagen deposition with more significant wrinkle reduction.

Fractionated laser therapy has been introduced to deliver results comparable with traditional laser therapy, but with decreased healing time. Fractional lasers work by treating a percentage of the skin surface area, usually between 5-30%, with spaced, deep penetrating, laser microcolumns that leave intact bridges of skin between the treated areas, thereby, decreasing the risk of complications associated with conventional full skin resurfacing techniques, while maintaining the deeper benefits. Thermal energy is delivered to the deeper dermal elements to trigger collagen formation, while treating the deeper photoaging dyschromias and brown spots, and allowing for faster recovery due to the intact bridging of skin. Today, the state of the art in laser resurfacing techniques combines conventional full skin resurfacing to remove the epidermis, improving the epidermal elements, followed by fractionated therapy to treat deeper photoaging and stimulate deeper collagen formation and wrinkle reduction.

Skin rejuvenation therapy must be tailored by the patients, not the physicians goals. Aggressive therapy can lengthen healing times and increase the risk of complications, but also have the best results. Maintenance therapy with medical grade skin care products and superficial rejuvenation agents, with interval medium to deep rejuvenation therapy is ideal for optimal outcomes. Skin resurfacing/rejuvenation should be viewed as complimentary, not a substitute for face lift surgery. The choice of resurfacing agents used to achieve the patients goal is collaborative and based on the comfort of the patient with the rejuvenation agent and the experience of the physician.

Medical Science Has Yet To Find A Cure For Mononucleosis

blogger /

Self-care is the most effective cure for mononucleosis. This medical problem is also called ‘mono’. It is a viral infection that usually goes away on its own. However, you can help it on its way by getting lots of bed rest and looking after yourself properly. It is caused by the Epstein Barr Virus (EBV) and is most common in teenagers and young adults.

It can occur in children but, because the symptoms are less severe, it often goes undetected. It is not likely to affect older adults because their immune systems have developed immunity over time. Mono has also been termed the ‘kissing’ disease as it can be contracted by kissing. It is also spread through throat and nose mucus, tears, and saliva.

If you think you have mononucleosis, don’t kiss anyone and don’t share toothbrushes, glasses, plates, or food utensils. When you recover, the symptoms will never return but the virus will still live in your system. This means that other people can still be infected. The typical symptoms associated with this condition are fatigue, swollen glands, weakness, sore tonsils, sore throat, and high fever. These usually begin 1 to 2 months after contact with the virus.

Mononucleosis may cause the spleen to swell and even burst. An indication of a ruptured spleen is a severe pain in the left side of the upper abdomen. If this type of pain is experienced, contact a medical doctor immediately.

As mentioned, self-care is the only real cure for mono. The patient should get plenty of bed rest – this means staying away from school or work until fully recovered. Gargling with salt and warm water, or sucking lozenges, can soothe a sore throat. Some medications containing aspirin, acetaminophen, and ibuprofen can reduce fever and relieve headaches. If the spleen, tonsils, or throat swell, corticosteroids may help.

An antibiotic cannot work because mononucleosis is a viral infection. Only if a secondary bacterial infection develops, will a doctor prescribe an antibiotic. Examples are a respiratory infection, an ear infection, or strep throat. Avoid playing sport and lifting heavy objects. Strain, impact, and over-exertion can easily cause a swollen spleen to rupture. In addition, exhaustion will occur and hinder the immune system’s ability to fight the virus.

Drink plenty of fresh juice and water to help your body get rid of toxins. Increase your daily intake of magnesium, potassium, and calcium by taking a supplement. These minerals boost the system’s defences against infection. To strengthen the immune system, use a supplement that has a high content of Vitamins A, B-complex, C, and E. Avoid red meat, processed foods, and saturated fats.

To prevent your immune system from weakening, do not eat from junk foods. Echinacea and astragalus are helpful herbs that can be obtained in the form of capsules, teas, or tinctures. Dandelion, thistle herbs, and milk can prevent mono from affecting the liver. These self-care recommendations should not be considered as a cure for mononucleosis. They can, however, relieve the symptoms and hasten recovery.

How To Win A Science Fair Contest

blogger /

A science fair contest is one of the first experiences that students have with real scientific exploration and experimentation. These contests are designed to not only stimulate an interest in science, but to also stimulate the creative subconscious of young scientists. Every year hundreds of these events are held across the country, some at local schools and some at major universities and science institutes. In order to win one of these competitions students need to learn how to create a project that is going to stand out in a good way from the other entries.

Tip #1 Age Appropriateness Counts

When a science fair judge looks at a project they are going to judge its value based partially on the age of the student and the complexity of the project. Students that create projects that are too simple for their grade level are going to receive lower scores than those students that create projects that are more complex than the average project created by someone of their grade level. A good way to select a project idea or topic that will be considered above your grade level is to examine text books or curriculum guides for science classes that are above your grade level.

Tip #2 Select a Topic That You Can Handle

While it is important to push the envelope in terms of project complexity, you do not want to over do it. You need to be able to understand your topic and its related concepts in order to complete your project with precision and accuracy. If you select a topic that is too complex then you may not be able to design an experiment that will be manageable for your skill level and available resources.

Tip #3 Take a Unique Approach

Uniqueness is one of the main characteristics that will be judged about your project. Uniqueness is very important to implement into the design of your project. You can make your project more unique by asking yourself if there is another way to solve your projects main question or problem, or if there is a better way to do something or if there is a more interesting way to approach your topic. These simple questions can help you to find new angles that the judges will be intrigued by.

Conclusion

Winning a science fair contest is not easy to do. There are few prizes to be won and many students try to win the top places in the contest. The best way for you to enhance your chances of wining a science fair contest is to plan out your project, put in your best effort and to organize your time so that you do not have to rush the completion of your entry.
