2 Angles make a difference Aim The aim of this experiment is to test whether the angle of sunlight affects the surface temperature on earth. Hypothesis I believe Block B will receive more sunlight than Block A‚ because the lamp shines directly onto Block B. Materials * * Lamp * 2 thermometers * 2 blocks of wood * Black plastic tape Procedure 1. Cut out two small identically sized pieces of black tape and attach onto wooden blocks so that they make pockets. 2.

Investigation – Storage conditions of Bleach & it’s relation with temperature. Title/Research Question: ‘How does temperature effect the concentration of chlorate ions in bleach?’ Aim: The aim of this experiment was to investigate the optimum temperature storage conditions of bleach’s stored at different temperatures. Introduction: Chlorine bleaches are made by dissolving chlorine in sodium hydroxide solution. They have a number of uses as they are used to remove colors‚ whiten or disinfectant

My final device was simple‚ yet effective. It consisted of a straw pyramid in a bag of popcorn. Two of the main restrictions for this project were mass and size. The bag that i put my materials in was within the size limit. The mass of popcorn and straws is very little. Popcorn can also absorb a lot of shock‚ stress‚ and kinetic energy. Straws absorb energy as well. So I decided to use those two materials. First‚ I put the egg directly into a pyramid of straws. Putting the egg in the pyramid instead

As the climate changes‚ coral bleaching is predicted to become more frequent and severe. Sea temperature increases and coral stress from other impacts may increase corals’ vulnerability to bleaching. As part of its Reef Health Incident Response System‚ the Great Barrier Reef Marine Park Authority has a Coral Bleaching Response Plan for detecting and responding to coral bleaching on the Great Barrier Reef. What is coral bleaching Many types of coral have a special symbiotic relationship with a

I. Introduction Background Research Most of the people die because of suffocation during fire incidents. Many people in the world also get respiratory problems because of insufficient supply of air or ventilation in their houses. During fire incidents‚ many people die because they sometimes inhale carbon monoxide that is poisonous for a human body. That is also a good way to find out if a person was alive or dead by the time the fire got to them; if they were dead before the fire got to them

After performing this experiment‚ it was found that the surface the chocolate was placed on could make a major difference. The hypothesis that was made had mostly incorrect predictions‚ but with some correct ones. It was found that using the palm of one’s hand was the best surface on which to melt chocolate‚ as was predicted. It melted so far‚ and so fast‚ that the experiment had to be altered. Coming in second place was the surface of black paper‚ something that was not expected. The black

Next I will pour the Zinc into the test tube containing CuSO4. 3.Finally I will measure the final temperature using a thermometer and record the temperature rise in °c. (I will carry out all my experiments under lab safety precautions.) Variables *I will vary the mass of Zinc‚ & use the following Zinc weights:

BI309 Lab-2 Name of student: Anisa Dreunibakarua ID #: S11033198 Title: Effect of Temperature and Stimuli on Simple Muscle Twitch. Introduction: Skeletal muscle is a type of striated muscle that is attached to skeleton to facilitate movement by applying force to bones and joints through contraction. Skeletal muscle generally contract voluntarily when stimulated by the nerve‚ although they can also contract involuntarily at times. Muscle action is controlled by the Nervous System

The earth doesn’t have an even balance of heat and the reason for this is because the earth is a geoid ‚ the sun’s rays hit directly on the equator(caused by unequal insolation due to three factors: angle of strike‚ atmospheric depletion and surface area.) and then move outwards towards the polar areas. The atmosphere together with the ocean currents work hard to try and even out the imbalance of heat energy by redistributing the air from the equator to the Polar Regions but also from the Earth’s

Introduction: The process of respiration happens in many organisms and species. For the lab study that we are going to conduct I choose Yeast as my organism. First off Yeast is a microscopic fungus consisting of single oval cells that reproduce by budding or fission (is the splitting of an atom)‚ and capable of converting sugar into alcohol and carbon dioxide. When making your own bread‚ you can buy yeast in the grocery store. The yeast contains little brown grains that will carry out cellular respiration
