FUN WITH CHEMISTRY
Chemistry is happening all around us. Have you ever wondered what makes popcorn pop, soda fizz, or super balls bounce? Students will investigate many household applications of chemistry in a series of fun-filled hands-on activities and experiments. |
CHEMICAL REACTIONS
Replacement, oxidation-reduction (redox), endothermic and exothermic are just a few of the controlled reactions your students will initiate in this laboratory exercise. Come explore the world of matter from alchemy to modern chemistry and see the impact it has on our daily lives. |

CHEMICAL/PHYSICAL CHANGE
Watch as solid carbon dioxide (dry ice) sublimates before your very eyes! Students will perform a series of experiments using this reaction to understand phase changes in matter. They will also experiment using various other chemical substances to investigate how these transformations occur (each student must provide a mitten or glove to handle the dry ice). |
CHEMICAL BATTERIES
Have you ever made a battery from lemon juice? It's surprisingly simple to do, when you combine the juice with two different metals. Students will experiment with various metals and liquids to create an array of different voltages. |
ELEMENTS AND COMPOUNDS
The ancients knew some of the elements but were probably completely unaware of molecular compounds as we know them today. Your students will work with elements in their pure forms, combining them with other elements to form compounds, providing a fascinating introduction to the world of basic chemistry. |
CRYSTAL GROWING
Crystals in nature take on unbelievably complex patterns, forming through a variety of processes. Students will grow their own "crystal garden" using Epsom salt, among other substances, to investigate different crystal structures. |
ACIDS AND BASES
What happens when you combine an acid with a base? Your students will measure the pH of several household substances and mix a few together to better understand the nature of acidity and alkalinity. |
ACID RAIN
Learn about pH and its relationship to water quality. Students will measure the pH of a recent rainfall using field meters, then learn what effects varying acidity has on the environment. |
