It was a grey day in the Savannah. Very foggy. I was worried because I couldn't see anything. It was even more eerie when I heard the laugh of a hyena. I brought my sandwich out but instead of eating it split it in half and threw into miserable doom of fog. I heard fighting and laughing until it was all silent. I was a researcher and researching hyenas. I hear footsteps and spin around. I jump up. "I'm dead." I think. No cant think like that. Have to try. I see my truck and climb in and race away.
Reflection/Questions We did a activity where we did things like walking then measured our heartbeat. In the activity I learned that your heartbeat takes a minute to slow down and that's why we could do this experiment. The most fun part about this was the part of moving around. It was just fun to spin and circles and jump at the same time and then check your heart rate. The hardest part was making sure to keep up with the beats per second. It hard because especially the jumping it went really fast and there was the 2 beats that was actually one so you needed to keep track.
