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.

 This science and math lesson uses coated candy and water to create a rainbow on a plate. It takes a popular internet activity and modifies it for the classroom. It's extended by having students hypothesize if other temperatures of water will work and if different colors of the candies run faster than others. It also meets the math SOLs because students can calculate the cost of the experiment and/or create graphs of the results of the experiments.  You could extend this activity into art or English writing by having students draw their rainbows or write about what they saw happening on the plate as a report writing. You could have them take it a step further and do a creative writing about what they think is at the other end of the rainbow. 

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.

In this lesson, the students will conduct an investigation to purify water. Students will engineer a method for cleaning water, discover the most effective way to filter water, and practice conducting a scientific experiment.
