Catapult: Flight of the Marshmallows
Watch your marshmallows fly. The engaging STEM activity has groups create a catapult to launch marshmallows. After testing their prototypes, they consider improvements and redesign their catapults.
Cornell University
Glued into Science—Classifying Polymers
Explore the unique characteristics of polymers. A complete lesson plan begins with a presentation introducing polymers. Following the presentation, young scientists develop a laboratory plan for creating substances using polymers. They...
Cornell University
Scaling Down: Effects of Size on Behavior
Two activities explore the concept of size, especially small sizes down to the nano. Scholars practice determining volume, mass, and density and calculate exponential increases and decreases. They then predict and test the effect of size...
Cornell University
Physics of Flight
Up, up, and away! Take your classes on a physics adventure. Learners explore the concepts important for flight. They experiment with the Bernoulli Principle while learning the forces that act on airplanes in flight.
Curated OER
Respect for All Kinds of People Inside and Outside the School
Fourth graders explore the concept of respect. In this diversity lesson, 4th graders play the Untangle Game and complete a diversity puzzle. Students consider how to emphasize similarities over differences.
Curated OER
Avoiding Run-ons
Students examine how to avoid run on sentences. They look at the sentences containing run ons and rewrite the sentence on the line the way it should be written. They work independently to gain practice.
Curated OER
Skateboard Disaster
Students conduct a hands-on experiment with collisions between two skateboards of different masses. They are introduced to the concept of conservation of momentum in collisions and consider how their observations might help engineers...
Curated OER
How Do Things Fall?
Students study forces by examining the force of gravitational attraction. They observe how objects fall and measure the force of gravitational attraction upon objects. Students discover that, since gravitational constants are different...
Curated OER
Follow Those Tracks
Students observe a picture containing patterns of animal tracks, infer what might have happened based upon the pattern of tracks, and write a story describing what might have happened.
Curated OER
Tadpoles
Students examine tadpoles at various stages of development. Questions in observation category assess students' ability to use a variety of senses to observe data in a certain way-scientific way.
Curated OER
Balancing Demands
Learners create a weekly timetable record of their activities for a week then use time management skills to plan a timetable for their next week. They examine the time management skills of a teenage Wimbledon player. They set goals and...
Curated OER
Chemical Changes and Biscuits
Fourth graders investigate chemical changes in everyday life settings, such as cooking. They investigate leavening which is one of the classic chemical changes that people experience. Pupils observe leavening in biscuits with the...

Students listen to Chapter I, Chapter II, Chapter III, and Chapter IV of "The Forgetful Pony". They observe different stages of development of mealworms. The student sequences pictures to show the life cycle and draws the developmental...
Curated OER
Sound Box
Students make simple observations and identify relevant variables, such as frequency and diameter. They then discuss the relationship between variables. The task assesses students' abilities to make simple observations and make...
Curated OER
Threads
Students group observed data, filtering from all their observations the similarities between burring threads. In the second part they make a comparison of a chosen attribute between the two threads.
Curated OER
Blue
Students follow directions for a simple chemical experiment. They use the appropriate tools and techniques to gather, analyze, and interpret data. Students identify a substance that has characteristic properties, such as density, a...
