They used giant cell phones, TVs for videos, and interactive TVs. Each were very effective because the exhibit was about cell phones and they made it interactive along with visually informative. Most of the materials are rare earth metals which aren't regenerative, but there are a lot of metals used to create the technology such as... They made a cycle of how phones the life of phones called the supply chain. The environmental impact of this are negative during the mining and manufacturing stages because they reduce the amount of rate earth metals and product carbon dioxide in the manufacturing process. One technological impact of phones are the . Two societal impacts of phones are the ease of connecting and access to information. The museum chose to display this on a wall by using pictures and diagrams of examples of connecting like texting or social media.

Walking Upright, Adaptation to Climates, and Bigger Brains. Humans have evolved from different circumstances. Humans used to walk on fours and then both fours and two and then finally just a bipedal system. In hotter climates humans evolved to be more narrow and have long legs whereas in colder climates humans evolved to be much broader and have shorter legs. Lastly, as humans evolved brain size increases along with the way the head hangs from the body. Brain size increased most rapidly when humans began to interact with each other and the environment in a bigger sense. Additionally, it helped for survival and critical thinking skills.     This section does not emphasize the human impact on the climate. There is only mention of how humans evolved, not the impact that it had on the planet as we evolved.

One of the videos titled The Titanic Wrecksite. This video gave a brief overview of how the Titanic sank and then went on to explain the condition it is in now that it has been at the bottom of the ocean for a while (it was covered in rusticles that were formed by bacteria eating away at the iron). Another video was titled Hurricane Storm Surge. This video gave context to how deadly hurricanes can be. It references the force of the winds and that vast amount of water that floods homes. Now people use SLOSH (Sea, Lake, Overland Surges from Hurricanes) to predict the height of the wave of water. This can help people understand how bad the storm is. I think the titanic information is known by the general public because it was taught in primary education, but SLOSH may not be as known because not every area is susceptible to hurricanes. It discusses the life progression of the earth and the ocean's role in the earth. The video stated the ocean was responsible for the production of oxygen and food. It is also home to phytoplankton which are important for food and the evolution of animals. This format was portrayed on a globe and it made the video a little more appealing since the events are happening on the earth which is a globe.

One pylon was from 22,000 to 20,000 years ago. Animals like the wooly mammoths were in the case. It was about 10 degrees cooler than today and the carbon dioxide and the atmosphere was at 280 ppm whereas now it's about 410. Additionally the sea levels are much higher now. Another pylon was grassland from 19 million years ago. There were falcons and camels in the case with a lot of grass and trees. Additionally, the carbon dioxide and the global temperature were both cooler than they are right now (60 degrees F and 450 ppm). These exhibits are effective in informing people about how the environment and climate has changed since it visually shows you the type of environment and the climate during the time period. This was a series of time periods from early to now (50,000 -4,000 yrs ago) and discussed the temperature change of the planet. Changes in the temperature and in the types of species were used to discover the past climate. This exhibit does not tell us about future climate change because it mostly focuses on the past. It shows graphs of what humans have already done to different environment and climates, but never ready predicts a future change with it. It does however, tell us about the current because it compares all these aspects with today.
