How do you use your five senses every day? Today we’ll make a jar to use all five senses and better understand how they work!

Temperature of Color
We normally think white has no color and that black is made of every color, but what if I told you it was the opposite? Because an object absorbs different wavelengths of light depending on its color, we can test this idea using the properties of heat! In this experiment, we’ll see how different colors of paper warm up in the sun, and we’ll also learn how light gives objects color.
Erosion in Action
Making Fog
Normally we plug something into an outlet or put batteries inside to get power, but did you know we can make electricity using lemons instead? When we drink lemon juice, the electrolytes help power our muscles and give our body power. However, when we stick a few common metals inside a lemon and create a circuit, the juice can power a light bulb!
Phones and Phonemes
Frozen Balloon Illusion
Have you ever seen the illusion where a stream of water appears frozen in mid-air? In this experiment, we’re going to put this cool trick to the test and learn the physics behind it. We’ll see the difference between laminar and turbulent flow, and also learn about the scientists who study it, like meteorologists!
Cabbage and Chemistry
Have you ever licked a lemon and wondered what makes it so sour? What about eating a piece of dark chocolate and being surprised by its bitterness? As it turns out, flavors like sour and bitter come from the food’s pH level. But we don’t want to test the pH of everything by tasting it— many substances are too dangerous to eat! Instead, we’ll learn how to determine a solution's pH level using a common vegetable: red cabbage.
Binary Code Bracelets
At its simplest level, a computer is a machine that processes information. It takes in data, processes it, and then responds to it. But computers can’t understand English. They can only understand one “language,” called binary. Binary is composed of only two digits— zero and one. Humans use many different coding languages to give computers instructions, but all of these languages eventually get converted into zeros and ones.
Lemon Battery
Normally we plug something into an outlet or put batteries inside to get power, but did you know we can make electricity using lemons instead? When we drink lemon juice, the electrolytes help power our muscles and give our body power. However, when we stick a few common metals inside a lemon and create a circuit, the juice can power a light bulb!

Making Your Own Pan Flute
Have you ever looked at an instrument and wondered how it makes such interesting sounds? Scientists explore this and many other properties of sound in a field called acoustics. Today, we’ll be making a pan flute and experimenting with sounds that have different pitches, also learning about their frequency along the way!
Floating Paperclips
Creating a Wind-Powered Pinwheel
Have you ever wondered why objects move? Turns out, this is a very big question in science! In this experiment, we will explore one of the three laws scientists use to study motion, called Newton’s third law. To test this law, we will build a wind-powered pinwheel and see how a force in one direction creates another force in the opposite direction!
