Crazy Concoctions

Chemical Engineering

Program ● Interactive ● Grades PK-2

The Junior Chemical Engineering classes introduce our youngest engineers to fundamental concepts of solids, liquids, and solutions. Students investigate the properties of several crazy concoctions and make their own samples of bubbles, play dough, flub, and more.

Chemical engineering is a specialized field of engineering that focuses on understanding the molecular structure of materials and objects, and relating this knowledge to synthesizing new technology. Chemical engineering has expanded in recent years to include subset fields such as Nano engineering, materials engineering, and process engineering.

Bubble Bliss

Students will explore properties of a liquid during this Bouncing Bubbles lesson. They will experiment concocting two different bubble solutions to determine which one produces stronger bubbles.

This lesson can be extended using the Wacky Wands lesson 

Chromatography

Students will create their own paint recipe and watch in amazement as colors slowly separate into their individual components in the Chromatography lesson.

This lesson can be used as an extension to the Primary Colors or a stand alone lesson 

Crayon Art

During this lesson, students will learn about the physical properties of crayons as a solid. They will design Crazy Crayon Art by heating and melting their crayons. They will compare and contrast two brands of crayons in both the solid state and in the liquid state as they melt.

Flub

During this lesson, students will make and investigate Flub, which is neither a liquid nor a solid. They will learn the term polymer and how it relates to Flub.

Foaming Fun

Foam can have properties of both a liquid and solid. During this lesson, students will create and investigate different solutions of foam and analyze their properties. Prepare to make a mess!

This lesson can be extended using the Hot and Cold lesson 

Glow In The Dark Dough

Students will have the opportunity to make their own play dough using simple household materials. Students will learn how different materials react chemically and how they can change the physical properties of their Presto-Chango Dough!

This lesson can be used as either a extension to Presto-Chango Dough or a stand alone lesson. 

Hot and Cold

Foam can have properties of both a liquid and solid. During this lesson, students will create and investigate different solutions of foam and analyze their properties. Prepare to make a mess!

Kelvin's Cookie Company

Students will get to experience this process firsthand and experiment as chemical engineers with various ingredient mixtures to make the perfect cookie dough recipe. Once students perfect their recipe, they will multiply it in order to make a batch in bulk to sell in exchange for play money in their very own bakery!

Kinetic Sand

Kinetic sand is a craze that has swept the nation! Kids everywhere are mesmerized by a product that allows them to build sand castles indoors. In this lessons, students will work together as chemical engineers to invent their own recipe for kinetic sand and then complete a series of tests analyzing the physical properties of their new invention.

Oobleck

During this lesson, students will explore Oobleck and its properties as a non-Newtonian fluid. Students will test the viscosity of three different items as the manipulate Oobleck to make it act like a liquid and a solid.

This lesson can be used as either a extension to Flub or a stand alone lesson

Order Up!

Who wants a piece of pizza? In this lesson, students will explore fractions while creating their own self made pizza, just like the princess in the story! Students will go though a step-by-step process to create and then cut their pizza into fourths.

Primary Colors

Students will explore the idea that pigments are dyes that produce color. This activity is designed to teach students about the basics of making paint and chemical separation through an easy-to-understand demonstration with marker dye.

This lesson can be extended using the Chromatography lesson 

Secret Inkers

Chemical reactions are cool, but when you have certain chemical reactions you can create some really mysterious designs. In this class students explore how acids and bases react and use what they’ve learned to write their own secret messages.

This lesson can be extended using the Shinny Pennies lesson

Shiny Pennies

In this extension, students will investigate real world uses for acid-base reactions and explore the anti-oxidizing properties of common acids and bases.

This lesson can be used as either a extension to Secret Inkers or a stand alone lesson

Survival Pack

Students will create their camp vests and creating their own survival kits. Campers will find out all about the great outdoors, and what it takes to survive out there! Students will play the role of chemical engineers as they create their own insect repellent from scratch.

Presto-Chango Dough

Students will have the opportunity to make their own play dough using simple household materials. Students will learn how different materials react chemically and how they can change the physical properties of their Presto-Chango Dough!

This lesson can be extended using the Glow in the Dark Dough lesson

Wacky Wands

In this lesson, students will create bubble wands in a variety of geometric shapes. After recording observations and using their data to draw conclusions, they will explore how the design of a bubble wand affects the bubble’s size and shape.
