PRODUCT DESCRIPTION

10 Pack of Science Sub Plans. There are 10 science articles (with questions and answer keys) in this pack of secondary science sub plans. This is a great solution to both science literacy and science sub plans for the busy teacher. Finding reliable and interesting science articles on the internet or in periodicals is very time consuming. Formatting online articles to fit a printed page can also be challenging and can often waste time and paper. Worst of all, it's often difficult to find articles that will engage your students. This is where this volume of articles comes in!

Besides using these articles for sub plans, they also help promote science literacy which is emphasized in many curricula including NGSS and TEKS standards.

I have created professionally written and designed articles that will grab your students' attention. They will save you a lot of time and give you no-prep, ready to go printables at your fingertips. Questions and answer keys have been provided for all articles. Each science reading article is 1 and 1/3rd pages of text with 2/3rd pages of questions. In total, only two pages (or one page double-sided) to print for each student.

***************************************************************************

✿ All the ten articles in this volume combined are worth $29.90 at $2.99 each, but you save 25% with this collection and only pay 22.43, so each article is reduced to costing only $2.24.

✿ These 10 articles can also be found in my Science Reading Articles MEGA Bundle
for over 35% OFF along with 40 other articles.

NUMEROUS USES:

The great thing about articles is that they can be used for a variety of assignments if not used for a sub plan. There is a call for increased science literacy and the use of informational texts in classes, as well as a push to make science relevant to students. Engaging science articles are a good way to meet these needs.

(1) No prep sub plans that are easy to hand out and collect.
(2) In school suspension plans that are handy for those unexpected times.
(3) Independent work for early finishers.
(4) No prep extra credit assignment.
(5) Homework assignment.
(6) Warm up work for the beginning of class.
(7) Assign at the beginning of the week and take up at the end.

INDIVIDUAL ARTICLES IN THIS VOLUME:


Article #41 – Natural Selection Explained
Students will learn about natural selection using specific examples. One example is the change in color of the peppered moth from its light colored form to its dark colored form. The other example is the dramatic change in the size of the giant insects of the prehistoric era to the much smaller ones we have today. Artificial selection is also discussed in contrast to natural selection.

Article #42 – The Evolution of Pretty Boys
Students will learn about sexual selection and how female mate choice has strongly influenced the physical and behavioral traits that have evolved in males. This is especially seen in bird populations like peafowls and birds of paradise where the males exhibit extraordinarily beautiful plumage and intricate and interesting courtship behaviors. Ronald Fishers "Fisherian runaway" hypothesis as well as other interesting evolutionary theories behind sexual selection are examined. Male competition using the example of elephant seal bulls is also discussed.

Article #43 – Living in Space Harms Your Body
Students will learn about the downsides of living in space. Time spent in weightless conditions lead to serious bone loss and almost immediate and severe muscle atrophy. It also leads to cardiac muscle weakening as well as damages the optic nerves. These and the other fascinating negative effects of space living are discussed.

Article #44 – Fossil Fuels Uncovered
Students will learn about fossil fuels, in particular: oil, natural gas and coal. They will learn about the conditions under which fossil fuels are created and what turns some organic remains into oil and natural gas, while other remains form coal. They will also learn about the negative environmental consequences of fossil fuel use (e.g. climate change) and a movement to "Keep it in the ground".

Article #45 – Love and Cupid's Chemicals
Students will learn about the three scientifically recognized components of love: sex drive (libido), attraction and attachment. They will learn about what characterizes each stage and the major hormones involved in each stage. Some interesting studies are also discussed which examine how lowering certain hormones affect libido and attachment. This is a great article to use around Valentine's Day if you don't need to use it for a sub plan.

Article #46 – The Zika Virus Emerges
Students will learn about the Zika virus, where it first came from, where it's spreading to, how it is transmitted, and the symptoms it produces. Also discussed is the link between Zika and microcephaly (babies born with small heads) which is the major concern with the Zika outbreak, and the potential for Zika to turn into a pandemic.

Article #47 – Fracking Facts and Fears
Students will learn about extracting shale oil and gas through the process of fracking. Conventional drilling versus fracking is compared. Horizontal drilling and the chemicals used in the fracking process are explained. The various concerns and risks surrounding fracking are discussed as well as the stance different countries have taken on the fracking issue.

Article #48 – The Science of Tattoos
Students will learn about the science of tattoos. They will learn how tattoos are applied, what makes them permanent, and how the immune system causes tattoos to fade. They will also read about how the immune system aids the laser tattoo removal procedure to help get rid of tattoo ink. The safety of tattoo inks is also discussed along with how they can be affected by MRIs.

Article #49 – Mitochondrial Eve
Students will learn about mitochondrial DNA and Mitochondrial Eve. Mitochondrial Eve is the most recent common ancestor of all modern anatomical humans. Students will read about how mitochondrial DNA has helped geneticists discover Mitochondrial Eve, about the research behind her discovery and about the implications of this research on the evolutionary origins of humans. Also discussed is how this data supports the Out of Africa theory of human migration and expansion.

Article #50 – Stem Cell Science
Students will learn about stem cells and stem cell research. They will read about the difference between embryonic stem cells and adult stem cells as well as understand the controversy over stem cell research. They will examine the difference between totipotent, pluripotent and multipotent stem cells. Lastly, they will read about the exciting advances in stem cell research opened up by the advent of IPSCs (induced pluripotent stem cells) which helps bypass many of the ethical issues in stem cell research.
