SCIENCE FAIR BOOKLET FORMAT

Use white bond paper, letter size, 1 inch or 2.5 cm of margin around the page. All the information is double-spaced using only Century Gothic, font with font size 12 and black.
The alignment of the information goes towards the left side, including the Heading. The only thing that goes centered is the Main Title, simple format; without bold or underlined. At the beginning of each paragraph, there must be 5 spaces or a Tab. It is very important to consider that the school’s name should be written in Spanish even when the text is in English. Titles do not have period at the end, and they can go with capital letter only at the beginning of each important word within itself. Punctuation with the modernity of the word processors has also changed. After a period, colon, semicolon, question mark or exclamation mark there will only be one space.
In case you use quotations or parentheses, the necessary punctuation, colon and semicolon as well as the period before closing it, goes inside the parentheses or quotations.
The page number will always be in the right upper corner of each page.
In case of including tables or figures, they should be numbered and labeled as "Table" or "Figure" according to each case.

5.3 Modern genetics uses DNA technology.

Lesson Vocabulary:
selective breeding, genetic engineering

5.3 Review
1. A GM organism has had a gene from another species transferred to its DNA.
2. sequencing the 3 billion nucleotide pairs in human DNA
3. Sample answer: add nutrients to foods, produce new and better drugs, increase food production, and screen for genetic disorders
4. selective breeding- selecting parent organisms to pass on traits to offspring; genetic engineering- isolating specific DNA, inserting it into another organism; both- producing organisms with desirable traits
5. no, because the trait is now coded for in all the organism´s cells
6. Sample answer: because it comes from a more natural source, or a source more similar to that of a healthy human


15.2 Organisms act in different ways.

Lesson Vocabulary:
predator, prey, competition, cooperation, symbiosis, mutualism, commensalism, parasitism

15.2 Review
1. compete for mates, cooperate for resources
2. compete, cooperate, or form symbiotic relationships
3. Sample answer: mutualism- bee and flower; commensalism- fish and jellyfish; parasitism- tapeworms in humans
4. Sample answer: Bittersweet competes with trees for space and sunlight, and has stunted their growth.
5. In a predator-prey relationship, one species benefits and the other is harmed. Parisitism is similar, but the effect is more dramatic because the parasite relies on its host for survival.
6. Sample answer: Tropical rainforests and coral reefs have many moe species than other ecosystems; more opportunities for mutualism.
