Microeconomics Study Guide, Part I
In this economics worksheet, students respond to 38 short answer questions regarding the economic laws of supply and demand and market structure.
Curated OER
Stellar Magnitudes
Students analyze the stellar magnitude scale. In this stellar magnitude lesson, students examine the stellar magnitude scale. Students predict the Sun's magnitude from various planets.
Curated OER
Your Weight on Other Planets
Students explore their weight on other planets. For this science lesson, students view a presentation about the other planets and complete a worksheet in which they make predictions about their weight on the moon and other planets.
Curated OER
Enhancing Uptake of Glucose in Rabbit Muscle Cells
Students observe diffusion of glucose through a cell membrane and research the function of chromium picolinate in glucose uptake into a cell. They conclude and understand the role of insulin and chromium picolinate in the uptake of...

Using the Scientific Method
Pupils practice using the scientific method. In this scientific processes instructional activity, students read and discuss the main parts of the scientific method. Pupils plan how they would conduct an experiment using the scientific...
Curated OER
Assessing Normalcy
Students define normal distribution as it relates to the bell curve. In this statistics lesson, students use the central tendencies of mean, median and mode to solve problems. They plot their data and draw conclusion from the graphs.
Curated OER
Why NP Min?
Students calculate the normal distribution. For this statistics lesson, students use the normal distribution to estimate binomial distributions. They define when to use NP and n(1-p) to make approximations.
Curated OER
Upside-Down Wings
Students use FoilSim to demonstrate that the graphic analysis of the airflow around one object can be used to hypothesize airflow graphs for objects as they are elongated from a sphere to an airfoil shape.
Curated OER
Design of Airfoil for Given Lift
Students use FoilSim to design an airplane wing that generates a given lift. As they change parameters such as airspeed, altitude, angle of attack, thickness and curvature of the airfoil, and size of the wing area, the software...
Curated OER
Lift Relationships
Students use FoilSim (downloadable) to determine how lift is affected by varying parameters on the Airfoil simulation.
Curated OER
Actual Airflow vs. Ideal Airflow: Stalls
Students use 3-D modeling techniques to observe the characteristic signature of the stall condition apparent on an airfoil at high angles of attack. They use FoilSim to compare the above with ideal airflow.
Curated OER
Aerodynamics
Students discover the basic principles of aerodynamics, including the roles and identity of natural forces involved. They examine how the force of gravity is overcome by the curved shape of an airplane wing and air pressure.
Curated OER
Let's Investigate Tooth Decay
Students conduct a simple investigation to explore tooth decay.
Curated OER
CAN'T TOUCH THIS!
Young scholars discover the best practical shielding material when dealing with radioactive substances. They draw conclusions based on availability of materials, price, and best shielding properties.
Curated OER
Bird Populations
Students gather data about bird populations. They study bird migratory patterns using the methods that researchers use. They write an essay explaining the differences between the four types of population movements.
Curated OER
Land Safely...
Learners model the preparation needed for a soft-landing on a planet or object in space. They do this by packaging a raw egg with certain material, and dropping the egg from a given height to test the packaging effectiveness.
Curated OER
Reading Trees: Understanding Dendrochronology
Students examine tree-ring dating and discuss the lack of water the settlers in Jamestown faced. They create paper tree rings, simulate rain patterns, and describe the history of construction paper tree sequences.
Curated OER
Building a Pill Bug Palace
Students make "pets" of isopods (potato bugs) to determine their preferred environment and food sources. They record their results on a bar graph and in a scientific report.
Curated OER
Unfold the Mystery of Mold
Middle schoolers research the conditions in which molds thrive. They apply the scientific method to develop a hypothesis, conduct research and test results.
Curated OER
Building Tetrahedral Kites
Learners work together to build tetrahedral kites. They must follow directions and the provided materials. They discover the engineering concepts needed to make the kite.
Curated OER
Keep the Environment Clean
Students discuss ways our environment becomes polluted. They make a list of ways to keep it clean.
Curated OER
Meteorology (Condensation)
Second graders define condensation and evaporation. They identify and describe the steps in the water cycle. They ask questions to end the lesson.
Curated OER
Predicting: Making a Hypothesis
Students analyze information from various sources to create a hypothesis about the origin of a family artifact. Students create a hypothesis about the origin of the item and write a paragraph explaining why they believe the hypothesis is...
