The classic egg-drop experiment gets a new bounce with an activity that asks pairs to design a lander similar to one used to land a rover on Mars within a fixed budget. The activity provides a great introduction to the idea of...

Students work to create a design that will protect an egg from being dropped from a one story floor. They test their prototype after it is completed. They write clear instructions and link aspects of the design process to the scientific...

Fifth graders record at least four hypotheses concerning what happens when they drop an egg from a high spot. They record at least five observations or supporting ideas about the egg drop. Students test gravity by dropping an egg from a...

Middle schoolers design, revise and construct a method for protecting an egg from cracking when it is dropped from a height. They work in small groups to develop their protection method and then collect and analyze data as a class when...

Students discuss the many different types of animal signs that can be used to identify and track animals. They participate in an hands-on activity in which they examine tracks, trails, homes, territory markings, and even "scat" left by...

Second graders engage in a lesson that covers the life cycle of a butterfly. They use the Kidpix software to create a drawing of the life cycle with the help of an illustration given by the teacher as a guide. Then students discuss the...

This resource explains why data collection is a great way to make informed improvements to a design, and how to do it. Data can be quantitative - such as a measurement of distance or time - or qualitative, such as an observation of...
