This review is on the first segment of the Grade 5 curriculum of "The Inquiry Project: Seeing the World Through the Scientists' Eyes." Water, A Liquid is a series of 5 investigations about water. Students use readily available materials such as water, sand and gravel to deepen their understanding of weight. Having a conceptual understanding of weight is important because students will use it when they begin exploring matter that is too small to be seen. The students are introduced to the study of matter by looking at images of ships sitting in a dry seabed in the Aral Sea. This introductory investigation will hook students because it is posed as a mystery and has a real life connection. Within this series of 5 investigations students will: -practice measurement using standard units -collect and record data -read a letter from an engineer -compare the weight of sand and water -use a digital scale -learn vocabulary -review volume, estimation -engage in discourse -reflect on the weight of small bits of matter -summarize evidence -collaborate -develop strategies -observe -transform (by crushing). The Inquiry Project is a quality curriculum developed pre-NGSS but closely aligned with The Framework of K-12 Science Education. This curriculum "links the three dimensions together" through the qualitative and quantitative measurement of water and sand using standard units and student observations. Each lesson is "designed to link with the previous lesson" as students build toward the capacity to be able to "make observations and measurements to identify materials based on their properties" in the context of the dry sea phenomena.

There's no need to don a space suit if you want to experience weightlessness. In this video segment adapted from ZOOM, two members of the cast drop a cup of water with holes in it to demonstrate how free fall can create a momentary condition of "weightlessness". Recommended for: Grades K-8

Students begin to explore the idea of a force. To further their understanding of drag, gravity and weight, they conduct activities that model the behavior of parachutes and helicopters. An associated literacy activity engages the class to recreate the Wright brothers' first flight in the style of the "You Are There" television series.

Students learn about friction and drag two different forces that convert energy of motion to heat. Both forces can act on a moving object and decrease its velocity. Students learn examples of friction and drag, and suggest ways to reduce the impact of these forces. The equation that governs common frictional forces is introduced, and during a hands-on activity, students experimentally measure a coefficient of friction.

In this open-ended design activity, students use everyday materials milk cartons, water bottles, pencils, straws, candy to build small-scale transportation devices. They incorporate the use two simple machines a wheel and axle, and a lever into their designs. Student pairs choose their materials and engineer solutions suitable to convey pyramid-building materials (small blocks of clay). They race their carts/trucks, measuring distance, time and weight; and then calculate speed.

The engineers at Splash Engineering (the students) have been commissioned by Thirsty County to conduct a study of evaporation and transpiration in their region. During one week, students observe and measure (by weight) the ongoing evaporation of water in pans set up with different variables, and then assess what factors may affect evaporation. Variables include adding to the water an amount of soil and an amount of soil with growing plants.
