FIRE RESISTANT BALLOON: Materials - 1 matchbox - 1 candle - 1 yellow colored balloon - 1 blue colored balloon - Half a cup of water Procedure: 1. For this experiment‚ the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount

The floating egg experiment – How much salt is needed to make an egg float? Aim: To investigate the effects of salt on the density of water (and therefore the ability to float an object in said water) and to find the amount of salt needed to float one regular egg in a glass of water. Research: Internet research shows that adding salt to water increases the density‚ and in turn makes it easier for objects to float. 4-10 teaspoons of salt in 1 glass of water is said to be enough to make one egg

the question you tried to answer. Answer: How salt effects the temperature of the water hot and cold? (3 points) 2. Which observations or experiences helped you form your hypothesis? Answer: When I did beaker A which was cold with salt. And When I did beakers B-D that were hot with salt. (3 points) 3. State your hypothesis. Answer: If the water is cold with salt what way does the temperature go up or down. Verses if the water is hot with salt. (15 points) 4. Use the data from Part 1 of

electrode in another beaker. 4. Attach the electrodes to the voltmeter. 5. Roll a lengthy piece of paper towel and wet it with sodium chloride (salt bridge ) 6. Place each end of the salt bridge in the beakers. Make sure it’s dipped in the electrolyte solution. 7. Apparatus should be set as in the diagram below. 8. Keep spraying the salt bridge with sodium chloride to keep moist. 9. Record the voltmeter reading and observe clearly for any changes. 10. Repeat step 2 to 9 for

solid 15x150mm test tube clamp watch acetone Ice cyclohexane sodium chloride Lab Safety: Wear protective googles‚ apron‚ and gloves. Procedures: Prepare ice/salt/water bath Place 50g of solid NaCl in a 400mL beaker and add just enough water to dissolve the salt. Fill an 800mL beaker 2/3 full of ice‚ and then pour salt water mixture into the beaker‚ stir. In the hood‚ into two nested test tubes‚ add 10 mL of cyclohexane from a buret. Record initial and final buret readings. Then measure

Introduction : Copper(II) sulphate‚ is a type of salt which it is formed by combining both copper ion and sulphate ion through the experiment of double displacement between dilute sulphuric acid ‚ and copper(II) carbonate ‚ . Through this process‚ the copper ion will displace the hydrogen ion as it is more electropositive and sulphate ion will displace carbonate ion as it is more electronegative. The resulting copper (II) sulphate solution when cooled can easily crystalize

mass an object has. Adding salt to the water adjusted the water. Squeeze the bottle hard enough‚ putting pressure to the packet. This causes the bubbles to get smaller and the entire packet to become more dense. Objective: The objective of this experiment is to find the density and buoyancy which is an upward force exerted by a fluid. Hypothesis: Think that all the packages are going to float and when squeezed‚ the package elevates more. It will sink as you add more salt Materials: A 1 liter

Put the remaining mixture‚ containing sand‚ benzoic acid‚ and table salt into your beaker and add 50 mL of distilled water. b. Set up the beaker stand and burner fuel and heat the beaker of solids and water to near boiling. Stir the mixture to make sure all soluble material dissolves. At this point‚ the benzoic acid and
