Frequency of Outcomes in a Small Number of Trials
Science Fair Project Idea
Scientific Method
People often draw conclusions from a small number of observations, and use those conclusions to evaluate the likelihood that an event will take place. But how easy is it to draw the wrong conclusion based on those observations? Will your predictions be accurate if an experiment is only performed a few times? The objective of this project is to determine what happens when a test with two equally-likely outcomes is performed only a small number of times. You can test this by flipping a coin. A… Read more
From Your John to the School Lawn: Is Recycled Water Really Safe?
Science Fair Project Idea
Scientific Method
Reclaimed (treated) wastewater can be used for many purposes, including landscape watering and freeing up valuable fresh water for other purposes (like drinking water). It's a great way to conserve water, but is it really safe? This science fair project is designed to find out. Read more
Fruit and Gelatin Science: Weekly Science Project Idea and Home Science Activity Spotlight
Blog Post
In this week's spotlight: a pair of science projects from the kitchen. Is a gelatin-based fruit salad in your recipe book of family favorites? What fruit do you add? Will any fruit work? Put it to the test with this week's hands-on science exploration and investigate what the enzymes in certain fruits have to do with whether or not a gelatin will solidify properly when a fruit is added. Which Fruits Can Ruin Your Gelatin Dessert? (full Science Buddies Project Idea) Solidifying… Read more
Fruit Juice Distillation
Blog Post
Explore the process of distillation with a kitchen chemistry activity using fruit juice. What role does boiling the juice play in the process? Mixing water (a solvent) and sugar (a solute) together will give you a solution, a homogenous mixture in which the solute has completely dissolved. You can reverse the process and separate the solution back into its parts using distillation. (Note: there are some solutions for which distillation does not work!) In this week's… Read more
Fun or Frustrating?
Science Fair Project Idea
Scientific Method
Is winning correlated with fun? Pick a video game which has different difficulty settings, for example easy versus hard mode. Ask volunteers who have never played the game before to try it out. Some of them should use the easy mode and others should use the hard mode, this will ensure that you have a range in the amount of winning and losing among your volunteers. Keep track of how much each player is winning. Survey the volunteers to find out if they like the game. Do people who win more like… Read more

Fungi Spores
Science Fair Project Idea
Scientific Method
Mushrooms are not plants, but are fungi. Fungi include mushrooms, molds, and lichen. They do not produce seeds to reproduce like some plants. Fungi produce spores, like more primitive plants do. The spores of a mushroom are contained in the tiny folds around the stem underneath the mushroom cap. Different species of mushrooms have different types of spores, with different colors and different patterns of folds. You can make mushroom prints by removing the stem from a mushroom and placing the… Read more

Gas and the Size of a Marshmallow
Blog Post
In this family STEM activity, students explore the science behind the size of a marshmallow. What happens if you add or remove air around a marshmallow? Families can see science in action by experimenting with stretchy, gooey marshmallows. Gas Inside and Gas Outside Marshmallows contain hidden gas that is trapped inside when they are made. Balanced by the gas (air) outside, marshmallows stay a certain size. But by manipulating the air surrounding a marshmallow, you can force a… Read more
