Properties of Acids and Bases
Students observe and investigate properties of acids and bases. For this acids and bases lesson plan, students perform 5 different experiments including reactions of acids and metals, reaction of acids with carbonates, neutralization...
Curated OER
Taste Buds
Students investigate taste buds. In this taste buds lesson, students identify the four basic taste buds and their locations on our tongue. Students participate in an experiment to investigate how our taste buds work.
Curated OER
Acid Rain
Learners perform experiments to determine how different acids cause acid rain. They measure the pH of the water to calculate the water's acidity. They discover how acid rain dissolves rock materials.
Curated OER
Structure of Seeds and Effects of Fertilizer on Plant Growth
Investigate the structure of seeds and the effects of fertilizer on the growth of plants. Young scientists observe a peanut and determine if it is a monocot or dicot plant. They plant seeds and make varying solutions of fertilizer, then...
