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
Fruit Ripening
Science Fair Project Idea
Scientific Method
Fruit is a strategy some plants use to attract animals to disperse seeds. The animals eat the fruit and disperse the seeds through the digestive system. To attract animals, fruit needs to ripen and develop an odor that acts as an attractant. How much more successful are ripe fruits at attracting animals? Try setting out an over and under ripe piece of fruit, and compare how many many insects are attracted to each fruit. How does ripening occur? You can do an experiment using a very ripe… 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

Game of Life
Science Fair Project Idea
Scientific Method
The Game of Life is the invention of the mathematician John Conway. It is a cellular automaton, consisting of a grid of squares that turn "on" or "off" depending on simple mathematical rules that involve neighboring squares. Depending on how the grid is first set up (i.e., the initial conditions), various interesting patterns appear. Can you write a Game of Life program in a programming language of your choice? If you are new to programming, check out these resources from the Raspberry Pi… 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
