it strips of the protective layer of the seed and speeds up the rate of germination. But the longer someone presoaks a seed‚ the greater the chance it has to rot. When presoaking seeds‚ one should avoid planting them in dry ground due to the risk of the moisture being taken out of the seeds instead of sticking with it to germinate‚ leaving the seed back to its original state. purpose - There are many factors that affect germination‚ however this lab will determine how moisture‚ specifically presoaking

Butter lab 1 Introduction: While doing this experiment we used 3 terms. We used cream‚ butter‚ and butter milk. Cream is unhomogenized butter. Butter is what we got after the lab was finished. Butter milk is the milk around the butter after it is homogenized and it is thicker than normal milk. If we shake the cream in a jar than will it turn into butter? If I shake the cream than it will turn into butter because it will homogenized. In this lab you will shake a jar of cream and see if will

Enzyme Lab Marcus James. December 20‚ 2013 HL Biology 3 Period 1 Purpose and Background The purpose of this lab is to explain how enzymes act as catalysts for biological reactions in different temperatures. This lab relates to enzymes‚ proteins‚ and substrates; that we learned in class. The union of the enzyme and the substrate is called the enzyme-substrate complex. The make-up of an enzyme is proteins and made up of chains and amino acids. Enzymes

Does concentration affect the speed of chemical reactions? Problem: We are proving that “concentration” (the amount of reactants) is one of the things that can affect the speed of chemical reactions. We are also finding a way to keep the lid on the film canister for the longest period of time. We are using vinegar and water as reactants and changing the concentration every time to see the difference between the rates of reactions speed. Materials: - 1 graduated cylinder - 1 film canister

All the twenty nine weather stations are distributed quite evenly in the entire kingdom. A spatial interpolation technique is used to predict the wind speed between the weather stations‚ where direct measured data is not available. In this analysis‚ the method used to convert the point data into raster format is the inverse distance weighted‚ IDW. It determines cell values using a linearly weighted combination of a set of sample points. The weight is a function of inverse distance. The surface being

In the 1920’s before sound was introduced into film we had silent films. Stories were told through expression and even music. Pianists‚ complete orchestras‚ organists‚ and even some actors and narrators were invited by theaters to accompany the films being shown (Silent Films). On the Info Please website‚ the author of Movies and Films writes "by the 1920s‚ silent film writing‚ acting‚ photography‚ and music had reached an aesthetic pinnacle: very subtle emotional and plot nuances could be conveyed

Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

Lab Report: Toothpickase and Enzymes September 19‚ 2012 Olivia DePhillips Lab Partner: Joy Morgan Meyers Signature: Introduction Enzymes are biological molecules that catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process‚ called substrates‚ are converted into different molecules‚ called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Like all catalysts‚ enzymes work
