Science: Wind Power
Students build models of wind turbines and experiment with different designs that will improve efficiency. Students will understand the use of wind power as a renewable resource.
Curated OER
Conceptualizing an Experiment
Students work together to design an experiment. They discover the origin of a family artifact. They analyze the data and discuss the results. They determine if the experiment is the best way to find out this type of information.
Curated OER
Scientific Method
Learners explore how to use the scientific method to solve problems. In this scientific lesson students define terms, apply the method to problems and search the internet and find sites that cover the scientific method.
Curated OER
The Spectrum of a Star
Tenth graders identify stars based on their line spectra. In this astronomy activity, 10th graders analyze spectrograph and determine the elements present in the star. They explain the relationship between temperature and star classes.
Curated OER
Survival
Students determine the best material from which to make a jacket to keep the body warm in a cold, dry, windy climate. This task assesses the student's ability to perform an entire investigation. In this question the independent...
Curated OER
Mapping Animal Behavior
Learners discuss the value of sampling in science. They, in groups, map cricket movement in response to various stimuli and graph their results.
Curated OER
Unknown Liquids
Learners must design and conduct an experiment to determine which unknown liquid has a greater density based on basic information about the liquids and containers. Students are given specific materials to work with.
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...
Curated OER
Pond-water Populations
Students design and conduct and experiment on algae, for a two week period, to answer the question "In your investigation, how does changing one factor affect the growth of organisms?"
Curated OER
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
Erosion
Students design and conduct an open-ended investigation using a variety of earth materials to answer a questions posed by the teacher: How does the erosion of sand compare with the erosion of gravel? After producing evidence that...
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
Barometer Investigation
Students construct a barometer to use in an experiment that they design to measure the air pressure on a daily basis. These observations of air pressure allow students to determine how weather is affected when a storm is approaching and...
Curated OER
Pendulum Problems
Ninth graders explore how pendulums function. In this pendulums lesson plan students complete a pendulum lab activity.
Chemistry Collective
Chemical Potential: Staircase Demonstration
It's all uphill from here! Scholars examine the pattern of random particle motion up a staircase. The simulation shows how the linear increase in energy corresponds to an exponential decrease in particle concentration.
American Chemical Society
Racing M&M Colors
More than anything, this is great practice in scientific inquiry. After discovering that the color coating of an M&M® dissolves in water during a preceding activity, investigators now question whether or not the color makes a...
