Writing a lab report doesn't have to an impossible chore. Science experiments are a fun and hands-on way to test and observe theories in action. There are millions of simple experiments that can be done with just a small list of items. By keeping it relatively simple, it will be easier to write up the results in the report. Find an idea that you have a lot of interest in and are curious about, and that will make writing it up all the easier.
Effect of Acetic Acid on Calcium Carbonate
This is a simple experiment that demonstrates the chemical reaction that occurs when calcium carbonate and acetic acid are combined. Drop either a raw or a boiled egg into a container of vinegar so that it is completely submerged. Leave it for one day. Take it out and feel it. The carbon bubbles out and the egg shell becomes soft.
Different States of Matter
This experiment demonstrates the differences between some of the states of matter. Put some cornstarch into a pie plate and mix with enough water to give it the consistency of pancake batter. Add a little food coloring and play with it, then leave it. Compare this with what happens if you put your hands in a pie plate filled with water (liquid) alone and a pie plate filled with corn starch (solid) alone. The cornstarch-water mixture is a suspension which falls somewhere between a solid and a liquid.
Carbon Dioxide from Yeast
Yeasts are microorganisms that release carbon dioxide as they convert sugar into energy. Pour a little warm water into a bottle and add an envelope of yeast, swirling the bottle to dissolve the yeast. Add about a teaspoon of sugar and swirl again. Put a previously stretched balloon over the neck of the bottle and let it sit somewhere warm for about twenty minutes. The escaping carbon dioxide will inflate the balloon.
Lava Lamp Experiment
This experiment demonstrates intramolecular polarity, which is responsible for the separation of oil and water. Pour about 3/4 cup of water into a clear soda bottle and then slowly add vegetable oil until the bottle is almost full. When the oil and water have separated, add several drops of food coloring. Drop half of a fizzing (antacid) tablet into the bottle. The carbon dioxide released from the tablet carries colored water bubbles to the top where they burst, and the water returns to the bottom again. The tablet contains citric acid and sodium bicarbonate, which react when dissolved in water. This causes the gas to escape in bubbles.
