Because of the Dominican Republic lack electricity, so we try to help them address light poverty problem, we came up with ways to provide electricity for them, and we had a vedio call with them to understand situations, during the call, the students asked questions about there to them, then we knew more question by this Vedic call. We found some energy-saving lamps to help them solve the problem of electric lighting.
Interactions Content: When the battery runs out, I will wrap the battery and throw into the recyclable trash. When I run out of water, I turn off the water every time. Never bleach when washing clothes. Rarely use plastic bags, can not do not. Unused lights are turned off.
Choices: Turn off the water when it is used up. Eat how much to buy, do not waste food. The food packaging should be thrown into the trash can not readily dropped on the ground.
Changes: We should not overfishing, should be appropriate fishing. To reduce the number of chemical plants and pollution levels, and away from residential areas. The amount of fertilizer used should be appropriate, not too much can not be too little.
Post Format: We should protect our environment from pollution, save resources and not waste.
Reproduction Content: While asexual reproduction only involves one organism, sexual reproduction requires both a male and a female. Some plants and unicellular organisms reproduce asexually. Most mammals and fish use sexual reproduction. Some organisms like corals and komodo dragons can reproduce either sexually or asexually. But in the long term (over several generations), lack of sexual reproduction compromises their ability to adapt to the environment because they do not benefit from the genetic variation introduced by sexual reproduction.
Meiosis Content: Meiosis is a division of the number of chromosomes in biological cells by half. Sex cell division, chromosome replication only once, the cells split two times in succession, which is the chromosome number halved a special division. Meiosis is not only a mechanism to ensure the stability of the number of chromosomes, but also a mechanism for species to adapt to the changing environment. The result of meiosis is that the number of chromosomes in mature germ cells is less than half that of primordial germ cells. Meiosis is a range of organisms that undergo sexual reproduction; the period is from primordial germ cells to mature germ cells.
Mitosis Contect: Mitosis refers to the process by which a eukaryotic cell divides to produce somatic cells. Mitosis, also known as indirect division, was first discovered in 1882 by W. Fleming and E. Strasburger in 1880. Characterized by the presence of spindle chromosomes, sub-chromosomes are evenly distributed to daughter cells, this division is generally found in higher animals and plants (animals and higher plants). Mitosis of animal cells and higher plant cells is different.
Content on how organisms grow: Every living organism begins life as a single cell. Unicellular organisms may stay as one cell but they grow too. Multicellular organisms add more and more cells to form more tissues and organs as they grow.
Marfan syndrome is a genetic disorder that affects the body’s connective tissue. Connective tissue holds all the body’s cells, organs and tissue together. It also plays an important role in helping the body grow and develop properly.
Connective tissue is made up of proteins. The protein that plays a role in Marfan syndrome is called fibrillin-1. Marfan syndrome is caused by a defect (or mutation) in the gene that tells the body how to make fibrillin-1. This mutation results in an increase in a protein called transforming growth factor beta, or TGF-β. The increase in TGF-β causes problems in connective tissues throughout the body, which in turn creates the features and medical problems associated with Marfan syndrome and some related disorders.
Because connective tissue is found throughout the body, Marfan syndrome can affect many different parts of the body, as well. Features of the disorder are most often found in the heart, blood vessels, bones, joints, and eyes. Some Marfan features – for example, aortic enlargement (expansion of the main blood vessel that carries blood away from the heart to the rest of the body) – can be life-threatening. The lungs, skin and nervous system may also be affected. Marfan syndrome does not affect intelligence.
Summary/Explannation: Because of the Dominican Republic lack electricity, so we try to help them address light poverty problem, we came up with ways to provide electricity for them, and we had a vedio call with them to understand situations, during the call, the students asked questions about there to them, then we knew more question by this Vedic call.
Define: I need to find an app that can help me with science 9
Dream: Use the PHET Simulations app to help me with some questions about science, or some questions I do not understand, I can use this app to help me.
Deliver: Find the experiment to help me learning Science 9, I can find a variety of experiments in the PHET, when I can not understand something, I can search for the answer there.
Debrief: The PHET app can show me some of the experimental, if some questions I do not understand,I can search in this app, the PHET will show me some of the experimental, and to help me understand, I think that app can help me with more question.
