Stimulus/Response in Invertebrates
Students design and conduct and experiment to determine how invertebrates react to an outside stimulus such as light and other stimuli. Student must develop a clear plan of action, collect data in an organized manner and analyze their...
Curated OER
Chemical Weathering
Students measure the effect of water temperature on the rate of a chemical reaction, similar to the interaction of a weak acid and carbonate rock, using hot water and effervescent antacid tablets.
Curated OER
Friction of a Block Weight
Fifth graders hypothesize and design an experiment to study the relationship between a block weight and the number of washers it takes to pull a block across various surfaces. Students graph results and apply their findings to a...
