Chemical Volcano The cinder cone of the volcano is formed using clay. You’ll need a lot less ’volcano’ material if you make a general volcano shape out of paper and then just cover it with clay. Erupting Volcano Ingredients 1:- warm water 2:- baking soda 3:- liquid dishwashing detergent 4:- vinegar 5:- You can color the lava by adding food coloring or powdered drink mix Make the Chemical Volcano Erupt To cause an eruption‚ fill the bottle most of the way full with warm water. Warm water produces

more acidic than a liquid with a pH of 4‚ therefore a liquid with a pH of 3 is stronger. Look at the ingredients for each liquid you tested. Which ingredients contribute to each of the liquid’s pH? Sprite: Citric Acid Apple Juice: Ascorbic Acid Baking Soda: Sodium Bicarbonate Shampoo: Citric Acid Conditioner: Sodium Carbonate Neutralization: Whenever you mix an acid with a base‚ they neutralize each other.

As stated previously the purpose of this experiment was primarily based on about chemical changes. Many chemical changes are viewed through a screen‚ or read from a book. In this experiment‚ chemical changes are viewed directly from the eyes of the scientist. The procedure first begins by gathering all needed materials. Next‚ laying the first powder on four wells‚ followed by the next powders‚ each powder was placed on four wells. The liquids were then placed on each powder using the four droppers

Methods/Materials I did three experiments. I mixed lemon juice and baking soda‚ammonia and vinegar‚ and finally‚ hydrochloric acid and sodium hydroxide. I did each experiment when the acid was 0‚ 20‚ 40‚ 60‚ and 80;all in degrees Celsius. Therefore‚ I could compare the exothermic reaction with the endothermic reaction at each temperature. For the Lemon Juice + Baking Soda experiment‚ I had a different set-up. On a beaker‚ which had baking soda in it‚ I put a stopper. The stopper had two holes that

Music‚ Math‚ and Science! by Mary Cozac Children learn concepts and develop through hands-on experiences. They learn to observe‚ question and be curious about their inside and outside environment. When children are encouraged to experiment and discover new things they acquire new concepts and new ideas which they transfer to other areas of development. Planned activities that explore music‚ math‚ and science can teach children many concepts and
