In this activity, students discover the relationship between an object's mass and the amount of space it takes up (its volume). Students learn about the concept of displacement and how an object can float if it displaces enough water, and the concept of density and its relationship to mass and volume.
In this activity, the students test the shelters they built in Lesson 3, Activity 1 for durability and water resistance.
In this activity, the students will use wax paper shaped as leaves and kite string to build a shelter to protect them from the rain. The students will then test the shelters for durability and water resistance.
In this activity, students conduct an investigation to purify water. They engineer a method for cleaning water, discover the most effective way to filter water, and practice conducting a scientific experiment. Through this activity and its associated lesson, student teams follow the steps of the engineering design process related to water treatment, as done by practicing engineers, including constructing and testing their designs.
In this lesson, the students will build a shelter in order to protect themselves from the rain. After the shelters are built, the class will perform durability and water proof testing on the shelters.
