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
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
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
Learners experiment with mirrors to explore the Laws of Reflection. In this experimental lesson students develop their own experiments and follow a list of assigned steps then report what happens in their activity.
Curated OER
Scientific Inquiry: Periodic Motion
Students 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
Science Show
Students research topics. They teach a lesson based on their chosen topic to other students.
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
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.
Curated OER
Mechanically Inclined
Eighth graders examine the mechanical advantage of an inclined plane through experimentation.
Curated OER
Determining the Relationship Between pH and Hydrogen Ions with Microcomputer Based Lab (MBL) and/or Calculator Based Lab (CBL) Equipment
Young scholars find the relationship between the variables based on experimental data. They determine mathematical relationship between pH and the amount of hydrogen Ions in solution.
Curated OER
"Tri-County" Project--Water Cycle
Students analyze the parts of the water cycle through research and experimentation. Particular attention is paid to the processes of evaporation and condensation.
Curated OER
Transportation System of a Tree
Students examine the transportation system of a tree and the speed with which nutrients and water move. Cross sections of the samples used are examined in class for experimental results.
Curated OER
Science: Put Your Heart into Engineering
Young scholars examine the heart and vascular system and the need for artificial valves. After explaining how heart valves function, they design their own heart valves for experimentation. They predict the speed of fluid flowing...
Curated OER
Tug-Push-Twist-O'War
Students explore through experimentation how choice of materials affects structures.
Curated OER
Transformation With A Firefly Gene
Students understand the process of bacterial transformation through experimentation. They describe the function of two important genes of the pBestLuc plasmid. They explain how to induce competence in E. coli cells.
