Have you ever added a spoon of sugar to your tea and wondered why it disappeared? Where did it go? The sugar did not actually disappear—it changed from its solid form into a dissolved form in a process called chemical dissolution. The result is a tea-sugar mixture in which individual sugar molecules become uniformly distributed in the tea. But what happens if you increase the amount of sugar that you add to your tea? Does it still dissolve? In this science activity, you will find out how… Read more

Temper, Temper, Temper! The Science of Tempering Chocolate

Science Fair Project Idea

Scientific Method

Nut clusters, chocolate-dipped candies, and chocolate-dipped strawberries are just some of the delicious goodies that have a thin, rich layer of chocolate wrapped around them. But how do pastry and candy chefs make these delectable treats? The first step is to melt and temper chocolate. Tempering is a process in which the cocoa butter in chocolate is hardened into a specific crystalline pattern. When the cocoa butter molecules are in this pattern, the chocolate is shiny and breaks with a sharp… Read more

It's probably difficult to imagine a time with no television, no movies, and no cartoons. But believe it or not, those times weren't so long ago! What did those kids do when they couldn't watch movies? One of the most popular toys during that time was a great-grandfather of the modern cartoon. This toy was called a "thaumatrope," and in this activity you're going to make (and test) your own thaumatrope to learn about how vision works! Read more

Pollination and seed dispersal are both crucial processes in a plant's reproduction cycle. These processes are helped along by many factors, including different animals. For instance, some animals disperse the plant seeds, while others transfer pollen from one flower to another. In this lesson plan, students will investigate the interdependence between plants and animals for pollination and seed dispersal by creating interdependence webs out of yarn. Based on their created interdependence webs,… Read more

NGSS Performance Expectations:

2-LS2-2. Develop a simple model that mimics the function of an animal in dispersing seeds or pollinating plants.

The Surprising Strength of Eggshells

Science Fair Project Idea

Scientific Method

Have you ever seen an arch structure in a building, such as over a doorway or surrounding large windows? Arches have been used for structural engineering since ancient times. This experiment tests the strength of a naturally occurring arch shape: the shell of an egg. How much mass do you think an eggshell can support? Read more

Train a Reinforcement Learning AI to Play Minesweeper

Science Fair Project Idea

Engineering Design Process

Have you ever played Minesweeper? Did you start clicking around randomly until you hit a mine? What did you think the numbers meant? Do you think a computer program can play Minesweeper better than a human? In this project, you will explore how to train an AI agent to play Minesweeper. Read more

If you pour water into a clear glass, what color is it? It’s clear, right? But what happens if you try to look through it to see the world on the other side of the glass? It looks a little distorted, maybe a little fuzzier and uneven. If water is clear, why can’t we see through it clearly? The answer has to do with how light moves through water, glass, and other transparent materials. Just like when you try to run in a swimming pool, when light tries to move through water or glass,… Read more

Volcanoes

Science Fair Project Idea

Scientific Method

The papier-mâché volcano is a real classic, but there are many other ways to make an even more exciting and interesting science project focused on volcanoes! To get started on your own volcano-based science project, you will want to first have an understanding of how volcanoes form. This is related to tectonic plates. The entire outer shell of the Earth, known as the lithosphere, is made up of tectonic plates that are constantly moving. There are seven or eight large tectonic… Read more
