In this experiment, we will use solar energy as a source, in order to obtain thermal energy that will allow us to obtain heat that will melt the marshmallows in the solar oven.

Practical demonstration of capillary action in plants and other household items

In this lab, we evaluate a polymer chemical reaction and the entanglement of these polymers that form an elastic compound that can be molded into a bouncy ball toy. Students will analyze the effect of temperature on the elasticity, or ‘bounciness’, of the ball.

The process of yeast metabolism is demonstrated to students from sixth to eighth grades, students are expected to be able to understand and explain by their knowledge acquired in this 20-30 minutes module this process, its phases, and its relevance for chemical engineering at the end of this module. This will be done through an easy and accessible experiment that allows participants to learn about the different conditions needed for metabolism as yeast breaks sugar (hexose) down. Additionally, they will be able to identify some of the optimal process conditions and relevance in the global...

Kids will learn about what viruses are, different types, and how chemical engineers and themselves can put a stop to viruses. They will be able to have a fun, interactive experiment that can be done at home with little to no mess!

While marshmallows are a sweet treat, they are also great for displaying scientific principles in daily life experiences. The main components that are found in marshmallows are sugar, gelatin, water, and air. The sugar gives the marshmallow its sweet taste, and the gelatin gives the marshmallow its squishy and bouncy texture. Water and air also help form the correct consistency of the marshmallow. If you have eaten marshmallows at room temperature and after the marshmallow has been heated, you will notice a significant difference in texture, size, and consistency. This experiment will take...

Students will be introduced to the concept of viscosity by dropping marbles into graduated cylinders filled with liquids of varying viscosities, and they will time the marble as it falls through the liquid. The viscosity of the liquid is inversely proportional to the velocity of the marble and will allow students to visually see the difference in the liquid's viscosity and mathematically calculate it with skeleton note equations. ...

The presenters will make a video detailing the process of making sidewalk chalk. The process consists of mixing Plaster of Paris with food coloring and water, and pouring this mixture into a mold. The audience will learn about exothermic chemical reactions, and be exposed to the basics of chemistry.

The module walks the audience through the science behind the pH scale while using a red cabbage concentrate as a pH indicator. The presenters will describe the differences between acids and bases such as taste (sour for acids, bitter for bases), texture (soapy for bases), chemical structure (-H or –OH presence), approximately 5 minutes. Afterward, students will be presented with safe, household solutions such as vinegar, coffee, and lemon juice for acids and dish soap, egg whites, and baking soda solution for bases. Then, with the new information, they can then make guesses on whether the...
