Predicting/Making a Hypothesis
Students analyze information from a variety of sources in order to create a hypothesis about the origin of an interesting family artifact.They create alternative hypotheses based upon available information to demonstrate that some...
Curated OER
Let it Grow, Let it Grow, Let it Grow
Students investigate, through a hands-on activity, in which type of soil a bean seed grows best. They create a bar graph representing each plant's growth in different soils.
Curated OER
Solving Systems by the Elimination Method
Pupils solve equations by elimination and use the TI to graph the lines and find the point of intersection.
Curated OER
Building Tetrahedral Kites
Middle schoolers 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
Wind Gauges
Students use FoilSim interactive software to become familiar with the way in which the flow of air across or around an airfoil affects its ability to create lift.
Curated OER
Wing Area Effects Problem Set
Students read an explanation from a NASA Web-based textbook on lift and an explanation on the FoilSim software package given below. They use FoilSim to evaluate the relationship between wing area and lift.
Curated OER
Velocity Effects Problem Set
High schoolers, after reading an explanation on lift from a NASA Web-based textbook and an explanation on the FoilSim software package given below, use FoilSim to evaluate the relationship between velocity and lift.
Curated OER
Characteristics of Lift and Wing Area
Students use FoilSim to complete the activity and investigate the factors that affect lift and how wing area and lift are related.
Curated OER
Lift Equation Problem Set
Students, after reading an explanation from a NASA Web-based textbook, demonstrate an understanding of the text by using it, along with FoilSim, to complete an activity to graph and interpret the lift equation.
Curated OER
Bridges: Local, National and Global Connections
Fifth graders examine the role of bridges in commerce and transportation. They create a schedule for building a bridge and how much money it would take to build one.
Curated OER
Investigation of Timbre
Students design an experiment to analyze the timbre of different instruments. In this physics lesson, students analyze the missing quality in sound. They discuss their results in class.
Science Buddies
Science Buddies: Scientific Method Variables/hypothesis
Find out what variables are in a scientific investigation and what the difference is between an independent, dependent, and controlled variable. Look at samples of different types of variables and find out what makes a good variable.
