This step largely follows the LED CUBE 3x3x3. We’ll need a total of 27 LEDs that will be grouped into three sets of nine. Each set of nine LEDs will share a common connection amongst their cathodes (negative leads). We’ll refer to each of these sets as a "level". Each of the nine LEDs on a level is connected to the corresponding LED on the other two levels through their anodes (positive leads). These will be as "columns". To start we’ll use a drill to create a jig out of a small piece of scrap wood

in grams) of potato cores placed in them overnight (approximately 10 hours)? 2. Hypothesis Alternative hypothesis: As the concentration of sodium chloride in the solution increases‚ the mass of the potato cores will decrease. If the solution they are in has a lower water potential than the potato cores‚ there will be net movement of water out of the potato cores. If the solution has a higher water potential than the potato cores‚ there will be net movement of water into the potato pieces. Therefore

Summary The poem begins with our speaker at his desk‚ his pen poised to begin writing. He gets distracted by the sound of his father outside‚ working in the garden‚ and this sends our speaker into a spiral of memories about his father working in the potato fields when the speaker was a young boy. The memory stretches even further back to his grandfather and the hard work he did as a peat harvester (there’s all kinds of hard work going on). Eventually‚ our speaker snaps out of his daydream‚ and we find

diffusion I will be using potato discs‚ of the same size and mass‚ in different concentrations of sugar solution to find out whether the mass of the discs increases or decreases depending on the concentration. I predict that when the sugar solution is 0% the mass will increase as there is less sugar in the water than in the potato. The water will then travel through a partly permeable membrane into the potato from outside. When the sugar solution is 20% the mass of the potato will decrease as there

Osmosis was clearly shown since the potato cylinders decreased or increased at different concentrations of sucrose. The results supported my hypothesis because for the 0.0 sucrose concentration the average percent change in mass was 16.9%. For the 0.2 concentration the percent change was 3

foam that can be measured. ANALYSIS QUESTIONS 1. a) Describe the effect of damaging the potato on the catalase activity. With the increased level of damage to the potato‚ there appeared to be more activity within the reaction between the catalase and the H2O2. b) Explain at the cell level why crushing or macerating the potato has this effect. When you crush or macerate the potato‚ you are breaking the cell walls of each individual cell. Once this happens‚ the catalase is

Title: Osmosis and water potential Aim of the experiment: Finding the water potential of potato. Biological principles: Independent variable: concentration of the solution. Dependent variable: percentage changed in weight of the potato strips. Controlled variable: size of the potato strips‚ it can be controlled by cutting the length of the strips. Procedure: Table 1. Concentration of sucrose solution table Concentration/ M | Sucrose Solution/ ml | Distilled

Connect one end of the white wire to one of the nails and then place the nail into one half of the potato. 3. Connect the other end of the white wire to the battery holder inside the digital clock. 4. Connect one of the pennies to one end of the black wire then put the penny into the same half of the potato as the nail with the connected to it. 5. Connect

Battery from Potato Introduction: Batteries generate electricity through a chemical reaction between two different electrodes and one electrolyte. Use of Copper and Zinc electrodes and Sulfuric acid as electrolyte is a proven method for this process. We are wondering if we can use any other liquid as electrolyte? This gave us the idea of using a potato as electrolyte. After all a fresh potato has a lot of juice that may serve our purpose as electrolyte. Problem: Can Potato be used to generate
