Elementary School "Trunks"

** H20 Olympics (Water Properties) - There are two lessons within this trunk. 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 part of the 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: 3.5(B,D), 3.9(A,C), 3.10(A)

* Incredible Journey (Water Cycle) - This is a great way to teach or reinforce learning about the water cycle. A playing field is set up (in the classroom or, better yet outdoors) with nine stations. Each station has a dice with drawings for other stations, and tokens. Through a simple roll of the dice and movement, students will play the role of a water molecule moving around the planet. Engagement include a description of the movement of water within the cycle and identify changing states of matter as water moves through the cycle. Includes a graphing component.

Science TEKS: 4.7(C), 4.8(B); 5.8(B,C)

Stream Erosion Models (Landforms) - This lesson leads students through how different landforms develop by building a stream table model. Rainfall will be simulated at the higher elevation, and a stream will form and flow through the sloped area. Erosion, deposition and a delta will be evident in the lower elevation. Supplies provided for individual student engagement.

Science TEKS: 4.7(B); 5.7(B)

Weathering, Erosion and Fossils - Students will identify the differences between the processes of weathering and erosion; distinguish between mechanical, gravity and wind erosion; and identify fossils found in the Texas Hill Country. A math based outdoor activity on dinosaur footprints is included.

Science TEKS: 3.7(A); 4.7(A); 5.7(A,B); 5.9(C,D)

MATH TEKS: 4.8C, 5.3I

Elementary School Models

Fourth - Fifth Grade Models Available for Loan:

NonPoint Source Watershed Model - Students will learn the definition of the term 'watershed' and observe how different lands uses have an impact on water quality. The model should also be used as a tool to teach about the water cycle. A wrap up activity (a game called NPS Attacks) provides a playful way to reinforce learned concepts. A detailed teacher lesson, narrative and all supplies are included with model.

Science TEKS: 4.7(B)(C),4.8(B); 5.8(B)

Social Studies TEKS: 4.9(A)(B)(C)

Coastal Watershed Model - Demonstrates coastal pollution sources and prevention. Explore 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. A detailed teacher lesson, narrative and all supplies are included with model.

Science TEKS: 4.7(B)(C),4.8(B); 5.8(B)

SS TEKS: 4.9(A)(B)(C)

Water and Wastewater Treatment Model - Students will be introduced to the concept of water treatment and distribution. Both water and wastewater (sewage) treatments plants are depicted on the model, as well as pumps and pipelines. A detailed teacher lesson, narrative and all supplies are included with model.

Social Studies TEKS: 4.9(A)(B)(C)

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: 4.7(B)(C) ,4.8(B); 5.8(B)

  • https://arcg.is/1n5LLX - Fourth - Fifth grade Story Map of the Guadalupe River Basin, featuring cartoon characters Lupe the Turtle and Edward the Armadillo. Led on a tour of the Guadalupe River Basin, students discover different ways water is used, exploring different communities that depend on the water, and endangered species dependent on the rivers.
  • https://www.discoverwater.org/ - An engaging, interactive website for all things water - suggested for grades 3-5. Topics include: the earth and water, water cycle, oceans, freshwater, watersheds, conservation and water use, healthy water - healthy people. Students can print handouts created in a science journal, save action items, and create a poster.
  • https://www.youtube.com/watch?v=0_c0ZzZfC8c - NASA Water Cycle animation - This animation shows one molecule of water completing the hydrologic cycle. Heat from the sun causes the molecule to evaporate from the ocean's surface. Once it evaporates, it is then moves high in the atmosphere and condenses to form clouds. Eventually the water molecule will fall as rain or snow. Ultimately, the water molecule arrives back where it started...at the ocean.
