In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar. The first part of the activity (candle burning) should be conducted...

Learners are challenged to create solutions that conduct electricity and make a buzzer buzz (or an LED light up). They are given water, salad oil, alcohol, and vinegar as liquids, salt and sugar as...

In this activity about the relationship between food and energy (page 1 of PDF), learners observe and quantify the growth of yeast when it is given table sugar as a food source. Learners will make...

Learners discover the bubble power of living cells in this multi-hour experiment with baker's yeast. Learners make a living yeast/water solution in a bottle, and add table sugar to feed the...

In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution. The goal of this activity is to provide an interesting experiment which learners of...

Some animals can swallow food whole, but humans have to chew. In this activity, learners will investigate what saliva does chemically to food before we even swallow. Learner will examine how their...

In this activity, learners explore what happens when polarized white light passes through a sugar solution. Learners use a relatively simple setup to investigate light polarization and reveal...

In this activity, learners mix several sugar solutions to investigate the property of density. Each sugar solution has a different density and color of the rainbow. The less dense sugar solutions...
