Science Exit Project: Weather Weather itself is the state of the atmosphere at a given time. The weather seems very difficult to predict‚ however it is not as complicated as it seems. After looking at the variables and breaking down the pattern‚ a prediction can be made of the weather. The goal of this experiment is to look at the weather conditions for a given month‚ and then tell what shaped it‚ or what caused a certain variable to change. Procedure/Materials: First‚ I made a chart of the weather

Elizabeth Au (1) Serena Chan (3) Sharon Chan (4) Christy Chan (5) BIOLOGY LAB REPORT Investigation of the effect of metal ions on enzyme activity Objective To study the effect of two heavy metal ions‚ lead (II) ions and silver ions on the enzyme activity of invertase. Introduction Hypothesis: The rate of enzyme reaction of invertase decreases and the reaction eventually stops as the heavy metal ions inhibit the enzyme reactions. Biological principle: Heavy metal ions are non-competitive inhibitors

in common; they all had a science consultant to help filmmakers get the science part of their fictional world right. In this chapter of Kirby’s book Lab Coats in Hollywood: Science‚ Scientist‚ and Cinema he argues the strong connection that exist between the cinema/filmmakers and science institutions/communities. In a world where science meets fiction it is important that the science is accurate to the highest degree. Even animated movies need to the help of a science consultant‚ like Finding Nemo
