acid to collide with the sodium thiosulphate particles. In the second box, the high concentrated solution there are more particles of hydrochloric acid, so the chance of collision is increased. Method I am aware that there are many safety precautions which I will have to follow: · Immediately wash hands and other parts of skin if incontact with hydrochloric acid as it is an irritant and is harmful to skin and eyes. · Rinse out mixture in flask and leave water running to get rid of the
Investigating the Relationship Between the Braking Distance of a Toy Car and the Height of the Ramp Planning To carry out this experiment safely I will ensure that the necessary safety precautions are taken place. Goggles and lab coats should be worn during the experiment. All likely safety hazards are eliminated. I will make sure the ramp is placed on the table in a stable manner and that I will ensure that the ramp is not too high. The procedure of this experiment is to first get a
bruises and even broken bones will heal, but damage to your brain can last a lifetime. You can prevent possible injuries from unforeseen disasters such as smacking the street, sidewalk, curb, a car, tree or anything else around you by using safety precautions. In some cases, we are required to use safety measures, while in others we are merely advised. For instance, while driving an automobile, the law requires for all occupants in the vehicle to wear safety belts. The reason for this law is because
plan proposed to the City of San Jose by Calpine Corporation to build a power plant in Coyote Valley. Nearby residents and several other organizations, including Mayor Ron Gonzales, are against this plan due to environmental hazards and safety precautions with schools and residents. It is possible the power plant can bring to San Jose several positive outcomes that will help develop the city into the center of the technology world. Although the power plant sounds like it would benefit San Jose by
Without Knowledge, Life Would be Worthless The quest for scientific wisdom does not progress too far; rather, it is merely at the origin of upgrading society. Because knowledge is a concept most important to the establishment of any society, it is the building block of the future. Without knowledge, there would be no means of advancement, for society would lack the potential to do so. In other words, human society is on the verge of experiencing, processing and making use of the vast amount
gif (22406 bytes) Apparatus: List: Stop watch Thermometer Splint Clamp Matches Boiling tube Heat proof mat Fuels: Firelighter, Wood, Ethanol, Paraffin, Wax. Method (Preliminary test): first of all, I will make sure I take all of the safety precautions, I.e. tie back long hair, use goggles and make sure the room is well ventilated. Secondly I will set out the apparatus and get all the equipment from the list (shown on the previous page). Using the measuring cylinder, I will put 20cm3 of distilled
Each wrecked aircraft has it’s own story to tell if properly investigated. However Air Force guidelines are quick to point out that investigators in their eagerness seek out the causes, often ignore safe investigation practices and common safety precautions. Air Force Investigators are maybe in even more difficult position due to the hazards that are unique to the military war fighting machines, I’ll discuss a few of these hazards briefly before I get into the steps of Air Force accident investigations
Investigating the Concentration of Plant Cell Sap Using Potato Tuber Cells An experiment to work out the concentration of plant cell sap using potato tuber cells First of all and the most important are the safety precautions we will take throughout this experiment · Wear safety glasses to protect eyes · Handling the acids carefully · Careful while using kitchen knife (And all the simple things such as not running etc.) Another important aspect before we start is making the
the clips to each end of the graphite paper. Ø I attached the 0-1mA shunt to the ammeter. Ø I read from the ammeter each time I cut down the length by using scissors. I did this till the ammeter got a reading near enough to 1mA. Safety Precautions Ø As I used scissors one should have handled them properly at all times for one could have been cut by the blade.
wire we were using was only able to wrap around the iron core 40 times. We decided to go up in steps of 5 so that the electromagnet was not too strong or too weak to pick up the paper clips. Safety Precautions While doing this investigation we need to be aware of any safety precautions. As we are working with electricity we must make sure the voltage is not set too high as the wire may over heat and will melt on to hands causing burns to the skin. Prediction I predict that the more
Sodium thiosulphate solution Ÿ Hydrochloric acid Ÿ 250 cm Conical flask Ÿ Thermometer Ÿ Measuring cylinder Ÿ Heat proof mat Ÿ Bunsen burner Ÿ Tripod Ÿ Stop clock Ÿ Wire gauze Ÿ White card with cross Safety Precautions: Throughout this experiment, I made sure that safety was one of my top priorities. I wore goggles at all times to protect my eyes I used a heatproof mat and tripod when using the Bunsen burner and took extreme caution when turning it on and
measure background radiation. The source was placed quite close to the counter (1cm) and the thickness of the absorber was increased each measurement. Experimental precautions: The distance between the tube and the source was kept constant The material used in each experiment was kept constant. Safety precautions were the same as the previous method but the absorber was changed using a stand and tweezers. Method for range in air of Alpha particles, Beta particles & Gamma rays:
How Temperature Affects the Rate of Respiration in Yeast Cells Aim: The aim of this investigation is to find out how temperature affects the rate of respiration in yeast cells. [IMAGE]Apparatus: The pieces of equipment I will be using are as follows: * Measuring Cylinder (10cm³ and 50cm³) [IMAGE] * Test Tubes * [IMAGE]Distilled Water * [IMAGE]Glucose solution (0.5g-1.0g) [IMAGE] * Yeast suspension (0.5g-1.0g) [IMAGE] * Water Baths (Electronic) [IMAGE] *
the substrate starch. This reaction, which I am going to investigate, is called the protein test for starch. Aim: My intention for this observation is to examine how the enzyme catalyses are affected by changes in temperature. Safety Precautions: In this investigation I am going to make sure that everything is as safe as possible and prevent any accidents from occurring. 1) I will wear safety glasses and a lab coat to prevent avoids danger. 2) I will tie my hair back, which

determine their enthalpy changes (DHs), and they will then be “added” to that of a given equation, the combustion of water, H2 + 1/2 O2 ® H2O DH=-285.5 kJ/mol. In this investigation we will be working with potentially dangerous chemicals and safety precautions must be made. Magnesium oxide is a respiratory and eye irritant, the dust must not be inhaled and all work with MgO should be conducted in the fume hood ( Cartwright,... ... middle of paper ... ...te, only having a 2.46% error.

is the most practical experiment to carry out in a school laboratory. I could have changed the temperature but I have done that experiment before in class. When carrying out my experiment I need to make sure I follow the following safety precautions: Ÿ To keep my lab coat fastened as the laboratory is very crowded. Ÿ Keep the experiment area clear and tidy to avoid spillages as hydrochloric acid is corrosive and can damage the bench. Ÿ Wear safety goggles so that the corrosive
regulations when riding is one of peoples first exposures to obeying the law. Cycling is a great way to exercise as well as a convenient mode of transportation. But before you start riding you should take a few minutes to consider some important safety precautions. II. According to the Bicycle Helmet Safety Institute, bicycle related crashes kill about 900 people a year and injure over half a million. Most bicycle deaths or accidents occur between 3-9 pm, and most often occur during the summer months
Equipment 2 beakers – to contain the raisins and the solutions. Scales – to measure the raisins and the sugar’s mass. Stopwatch – to measure the time taken. Tweezers – to pick up the raisins. I need to take the following safety precautions: - Don’t use fingers to pick up raisins. - Keep an eye on the beakers. - Don’t run with experiments. I will make it a fair test by putting the same amount of sugar solution in each beaker and the times recorded will be the same.
