Spectrophotometric Determination of an Equilibrium Constant
Students determine the equilibrium constant for a chemical system and use graphing techniques and data analysis to evaluate experimental data.
Curated OER
Termite Trails
Learners observe the behavior of termites and draw conclusions about their behavior. They record data as to termite behavior and recognize elements in the experimental design which must include a hypothesis.
Curated OER
Is the Probability Probable?
Third graders compare experimental results with mathematical expectations of probabilities. They utilize a worksheet imbedded in this plan to gain practice with the concept of probability.
Curated OER
Popcorn Neutrino Lab
Students parcticipate in a modeling activity that simulates the cyclical role of experimental and theoretical science. Initially, students measure the mass of popcorn. They also record predictions of the mass of the kernels after they...
Curated OER
Antisense Oligonucleotide Therapy
Students conduct Internet research on Antisense Oligonucleotide Therapy. They design a puzzle to represent these processes, read and summarize an article, conduct research, and design a theoretical experimental procedure.
Curated OER
Teaching Biology Through Problem-based Activities
Students plant seeds and observe the life cycle of the organism. They experimentally research the effects of radiation on seed growth. Students determine the effects of environmental pollutants on harvested seed.
Curated OER
What Does Your "Homunculus" Look Like?
Students determine the density of touch receptors in various parts of the body on the right hand side. They use collected data to draw a picture of the
"homunculus" of an experimental subject.
Curated OER
Air Pollution: Visible And Invisible
Fourth graders observe air pollution that is visible and invisible with experimentation. During the experiment the students collect data that needs analysis. The observations are recorded in the lab journal. The data also is represented...
Curated OER
Friction and Machines
Fifth graders experimentally determine the relationship of friction to the functioning of machines. They demonstrate that rollers can decrease frictional force and increase speed and research to discover other ways that friction can be...
Curated OER
Machines Use Energy
Third graders observe and discuss examples of friction. They discuss what experimentally increases and decreases friction. They then predict which surface will produce the most friction and verify the prediction.
Curated OER
What Goes Up Must Come Down!
Students hypothesize about the nature of falling objects, design an experimental test to answer the question using everyday objects, analyze data to form conclusions, and infer that mass does not affect the speed of falling objects. This...
Curated OER
Aphids and Ladybirds
Students record observations of ladybird beetles and aphids. They develop questions concerning the behavior of ladybird beetles and aphids that are testable by a classroom experimentation. Students develop an investigation.
Curated OER
Life in Extreme Environments - Lakes Under Ice
Students collect chemical, physical, and biological data from a local lake throughout the year. In addition, students discuss the design of an experimental structure for water collection at several specific depths as well as assess the...
Curated OER
R-Project
Students analyze the outcome of a scientific experiment using free downloadable software. They collect experimental data to use statistical software to determine if the observations are likely due to the treatment or random chance.
Curated OER
Laws of Reflection
Students experiment with mirrors to explore the Laws of Reflection. In this experimental instructional activity students develop their own experiments and follow a list of assigned steps then report what happens in their...
Curated OER
Scientific Inquiry: Periodic Motion
Young scholars construct their own pendulum. In this physics lesson, students design an experiment to find the factors affecting its period. They formulate a conclusion based on experimental data.
Curated OER
Is It Alive?
Eighth graders define the boundaries of living organisms. They determine what makes something a living organism and identify factors that constitute "living." Pupils write a conclusion about the evidence they found that yeast is alive...
Curated OER
Science Show
Learners research topics. They teach a lesson based on their chosen topic to other students.
Curated OER
Spinning Nickels
Pupils make predictions to figure out the probability of a spun nickel landing on either heads or tails. They test their predictions through experimentation. They create a graph showing the frequency for the number of heads.
Curated OER
A Veritable Circus: Investigating Balance
Students experiment with balance to learn about verticle balance, horizontal balance, center of gravity, and become active problem solvers and "scientists." Student engage in manipulating and changing experimental materials.
Curated OER
Spin, Spin, Spin That Body!: Figure Skating, Physics, Science, Winter Sports, Olympics
Students learn the scientific principles of centripetal force through research and experimentation.
Curated OER
Drops on a Penny
Eighth graders experiment to determine the number of drops of water a heads up penny hold. They create a stem and leaf graph of the class results and use the data for further experimentation on a tails up penny.
Curated OER
Chromosome Fusion
Students see how patterns can reveal events of the past, thereby merging elements of both experimental and historical science.
Curated OER
Introduction to Graphical Representation of Data Sets in Connection with Nuclear Decay
Students record data, make observations, and share in experimentation and discussion of numerical experiments.
