Middle School "Trunks"

GBRA has a "trunk" available for loan to middle schools. The trunk includes supplies for four independent lessons, as listed below. All trunk lessons are Project WET© activities and have a correlated online lesson. Checks for understanding are built into the digital learning lessons.

H2Olympics - there are two lessons within this activity. First, students will use water molecule models to learn about polarity, bonding, adhesion/cohesion and states of matter. There are 16 sets of the H20 model kits in the trunk. The second lesson includes several hands-on activities using water where students explore the water properties of cohesion and adhesion. Students will participate in various 'events', using common kitchen and household products (all provided).

Science TEKS: 7.6(A); 8.5(A)(D)

A Plume Problem - this lesson leads students on using data to trace the flow of contaminants in groundwater. Students are presented a scenario where people in a town are falling ill, and the water wells are suspected to be the cause. Data is collected from wells and evaluation of that data is used to determine the source of the pollutant. This activity includes using a topo map. Distance learning extras include an animation of how surface activities can have an effect on groundwater.

Science TEKS: 6.1(B), 6.2(E), 6.8(B); 7.2(E), 7.8(C); 8.2(E)

A Drop in the Bucket - this interdisciplinary lesson engages students in learning how much water is on the earth, and of that how much is freshwater; and of that how much is available for humans, plants and animals. Students will participate in the activity using common kitchen tools. The lesson wraps up with world population growth and availability of freshwater. Math calculations include rounding, decimals, and percentages.

Science TEKS: 6.7(A); 7.8(C); 8.2(B), 8.4(A), 8.11(D)

Math TEKS: 7.4(D)

Social Studies: 6.6(B)

Seeing Watersheds - this lesson leads students through defining a watershed and the contributing parts: headwaters, tributaries, receiving streams, lakes, bays, etc. Students will participate in the activity using common kitchen tools (all provided for independent learning). Students will use a topographic map to study the flow of water in a watershed.

Science TEKS: 6.8(B,E); 7.7(A),7.8(C); 8.9(C), 8.11(D)

Social Studies TEKS: 6.6(B), 6.21(F)

Trunks are free of charge for two weeks and will be delivered/picked up

Middle School Models

GBRA also provides models for loan to middle schools

Guadalupe River Basin Model - (a GBRA employee must accompany this model and present to the class) This 7 ft. long model is painted to depict the 10 major watersheds, major rivers and creeks in the Guadalupe River Basin. Elevations from headwaters to the bay are accurately modeled to depict natural river flow. Discussions about watersheds, land uses and water quality lead to a hands-on exploration of flow, nonpoint source pollution and elevation. Use of water, Kool-Aid and cocoa illustrate flow and movement of pollutants.

Science TEKS: 7.8(A,B,C)

NonPoint Source Watershed Model - Students will learn the definition of the term 'watershed' and observe how different lands uses have an impact on our water quality. The discussion includes human impact on the environment, and groundwater-surface water interactions. Use of this model includes a review of the water cycle. A teacher lesson, including step-by-step narrative for the teacher and all supplies are included with model.

Science TEKS: 6.1(B), 6.3(B), 6.5(B), 6.12(E); 7.3(B), 7.8(A,B,C), 7.10(A,B), 7.12(A); 8.11(B)

Coastal Watershed Model - Demonstrates coastal pollution sources and prevention. Use explores the coastal landscape with hands-on activities that bring to life impacts on wetlands, estuaries, oceans, beaches, barrier islands, groundwater, coral reefs, shellfish beds and more. Includes underground storage tanks, storm drains, septic system, effects of an oil spill, dredging a channel and even a resort community handling its own waste. Teacher lesson, including step-by-step narrative for the teachers and all supplies are included with model.

Science TEKS: 6.1(B), 6.3(B), 6.5(B), 6.12(E); 7.3(B), 7.8(A,B,C), 7.10(A,B), 7.12(A); 8.11(B)

Stream Table Trailer - (a GBRA employee must accompany this model and present to the class) Circling around a 12 ft. Stream Table Trailer (outdoors), students will participate in the formation of stream systems. Props include farming, ranching and urban land uses. Water flows through the system. A pre-visit narrative outlines opportunities for observations and discussions on erosion, deposition, deltas, and effects of pollutants due to human interactions with the environment.

Science TEKS: 6.1(B), 6.3(B), 6.5(B), 6.12(E); 7.3(B), 7.8(A,B,C), 7.10(A,B), 7.12(A); 8.11(B)
