When the Irish Potato Famine Struck Ireland On a sunny morning in 1845‚ Irish farmers were going to check their crops. A farmer named Abraham Fitz found black potatoes in his fields. He thought it may be only the one‚ so he moved over 4 rows and dug another potato out of the ground. This one was black and rotten. This causes Abraham to travel to his neighbors house and ask about their potatoes. His neighbor’s potatoes were black‚ rotten‚ and giving off a foul stench. This would later be discovered

Natalia Wierzchon A.P. Biology Lab: 1. Osmosis 09/10/2010 I. Introduction a. Purpose: The purpose of this lab was to observe the diffusion process of water‚ osmosis‚ as well as create an understanding of water potential‚ the basis of osmosis. The experiment proved how water molecules in a solution are able to move from an area of low solute concentration‚ high water concentration‚ to an area of high solute concentration‚ low water concentration‚ diffusing “down” the water gradient.

the effects of different factors such as temperature‚ pH‚ and concentration of substrate‚ on the activity of the enzymes. By conducting these three separate experiments also‚ three graphs are able to be obtained where the trend of each factor affecting on the enzyme activity is shown and described clearly. II. Hypothesis Experiment 1 (Effect of Temperature): As the temperature increases‚ the height of the bubble will increase too‚ indicating a faster rate of reaction. Experiment 2 (Effect of

For many‚ this is a difficult choice that they struggle to make. The late Chip Ellis‚ however‚ didn’t falter for a moment when deciding how he wanted to be remembered. He once proclaimed‚ “A hundred years from now it will not matter what my bank account was‚ the sort of house I lived in‚ or the kind of car I drove...but that the world may be different because I was important in the life of a child.” The only thing that Chip wanted in this world was to make a difference to a child. He believed that

Chocolate Chip Cookie It’s the "not so secret" secret recipe from Jacque Torres tried this at home. I’ve been making this recipe countless times‚ and have found that the following tips make this cookie absolutely perfect: - Don’t substitute the pastry and bread flours w. AP flour. I really believe that the combination of the pastry and bread flours give the cookie a nice slightly crunchy exterior giving way to a really tender middle. - Hand chopped chocolate chunks‚ NOT premade chips - I will

Making a Potato Powered Light Bulb Materials: A large potato Two pennies Two zinc-plated nails or screws Three pieces of copper wire A very small light bulb or LED light 1) Get a potato and cut it in half. Then make a small slit in each half just big enough to put a penny into. 2) Cut two pieces of copper wire and wrap one around one of the pennies a few times‚ and wrap the other one around the other penny a few times as well. 3) Take a third piece of copper

ARTIFICIAL INTELLIGENCE: BRAIN CHIPS When you think about Artificial Intelligence what thought first comes to mind. Robots maybe‚ would we ever think about Brain Chips being implanted into human brains? Sure‚ but how will Brain Chips plays a major role medically in are world’s future? In are near future‚ while we sleep they will transmit data directly from are brain to the computer and not miss a wink of sleep. Computer Interface is only the tip of the iceberg. Brain chips when they are implanted in

Introduction A. Background of the study Due to the overwhelming demand of plastic bag production and its effects on our environment‚ our landfills are crammed with these non biodegradable materials. Substances used in the manufacturing brought forth various harmful chemicals which worsen over time. As the destructive compounds such as Chloroflourocarbon were introduced‚ the complete deprivation of the Ozone Layer starts. However‚ scientists and nature preservers alike managed to overthrow this
