Students predict the behavior of coffee in a cup while it is dropped during a demonstration. They relate their observations to the weightless conditions that astronauts experience in space and discuss the concept of free-fall.

Fourth graders conduct an experiment to get them thinking about the invisibility of air, and to prove that air has weight.

Students participate in a science experiment in which they try and move gelatin cubes with and without a lubricant. They examine the concept of friction and resistance to motion.

Students experiment with one method of detecting infrared radiation. They simulate the detection of infrared radiation using a liquid crystal sheet.

Fourth graders observe a demonstration experiment showing air pressure. They explain air pressure by completing the worksheet.

Learners expand upon previous lessons with sled kites by varying the dimensions or materials while building a news sled kite while working in a team. They fly their original kites and the new ones under similar conditions to determine...

Students discuss movement of air currents and then experiment to create visible models of air currents. Students connect the model to weather patterns.

Students conduct an experiment to evaluate the accuracy of their senses.

Students they imagine they are Galileo and try to duplicate Galileo's experiments and results.

Students explore the aircraft used in World War II. In this World History lesson, students read an article that describes a "flying saucer" created by the Nazi's. Upon completion of the reading, students answer questions on the article,...

Students construct their own submarine following a certain procedure. In this physics instructional activity, students calculate the density of objects using a mathematical formula. They explain why some object floats in water while some...

Students investigate the factors affecting projectile trajectory. In this physics lesson, students calculate the range, time and speed of projectiles using mathematical equations.

Learners study the basics of parachuting.  In this flight and aerodynamics lesson students make a simple parachute and investigate different variables that can cause potential problems.

Students study how hot air balloons were created and the different types there are.  In this density and lift lesson students build their own hot air balloon.

Students explore the different types of lifters through a series of activities. In this physics lesson, students explain the mechanics involved in the lifter designs. They compare aluminum versus zinc lifters.

Students examine the Magnus effect and its history.  In this forces lesson students investigate the lift of a rotating cylinder.      

Students study the basics of a model rocket and its classifications.  In this rocket lesson students determine the flight duration of a model rocket.

Students build their own boomerang. In this physics activity, students trace the origin of this equipment. They practice throwing and catching them.

Your charges will enjoy putting together this model of the space shuttle and completing the three challenge activities described in the lesson. The worksheets embedded in the plan that pupils use to cut out their gliders are beautifully...

Ready, aim, fire! Launch to a new level of understanding as scholars build and test their own catapults. Learners explore lever design and how adjusting the fulcrum changes the outcome. 

Get the class up and going with a lesson that discusses how airplane wings provide lift. Pupils use their knowledge of Bernoulli's Principle to develop an explanation of how it creates lift on airplane wings.

Students participate in a series of activities to explore the types of food Americans eat, how food choices differ in various parts of the country, and how the availability of various foods has changed over time.

Glide into the study of flight. An engaging lesson has scholars research information on the Wright brothers. They develop props and produce a recreation of the first flight at Kitty Hawk. They then report on the event as if they were...

In this set of five lessons, learners analyze the important of food traditions, identity, and history. Students analyze how food traditions contribute to family identity, investigate family food traditions through interviews, and compare...
