Thomas Robert Malthus was a British economist‚ whose famous Theory of Population highlighted the potential dangers of overpopulation. In his famous An Essay on the Principles of Population‚ Malthus shows as that: ’the populations of the world would increase in geometric proportions the food resources available for them would increase only in arithmetic proportions’. In simple words‚ human population can increase at a faster rate than the food supply. Agriculture has diminishing returns. Therefore

Title: Boiling Red Water Materials: Water A clear glass or plastic cup Food Colouring (Optional) 1/4 cup Vegetable Oil 1 tsp Salt Procedures: Fill a glass 3/4 full with water Add 5 drops of food colouring Add the oil Add salt How it works: The salt brings the oil down with it as it sinks to the bottom of the bottle. When it reaches the water‚ the salt dissolves and the oil is then free to float back to the top. NOTE: this is not originally

There is one animal‚ the glass frog‚ that is native to this country and has a unique physical characteristic. Glass frogs have made their home in the forests of Ecuador and Peru and feature a translucent underside which makes their internal organs visible. They live remarkable two-phase lives‚ hopping from tadpole to frog. But there is an issue that has developed

Boiling Point Lab Introduction: The purpose of this lab is to learn about the calibration of a thermometer. In addition‚ we also investigated the boiling point of an unknown liquid to determine its identity. Chemical Responsibility: 1. Make sure to use glycerine (lubricant) and a towel to safely insert the thermometer into the rubber stopper. 2. Carefully operate the Bunsen burner and make sure to use rubber gloves when handling the boiling water of beaker 3. Always wear goggles

Purpose The purpose of this lab is to find the boiling point of the liquid and find the melting point of the solid. Procedure Boiling point: To find the boiling point of Isopropyl Alcohol I put about 1 mL of it in the test tube. Then I attached the thermometer to the test tube with a rubber band(make sure the thermometer bulb is lined up with the end of the test tube). After that I made a water bath with a beaker and put in the test tube with the thermometer. I then used a burner and a burner stand
