We experimented to see what happens to rocks as they slide down a mountain. We are continuing to focus on the forces of weathering, erosion, and deposition and how they create and/or destroy landforms.
We continued our weathering, erosion, and deposition learning with the stream tables. We experimented to see what happened when we increased the slope of the stream tables and when we simulated a river flood.
We are using Stream Tables to explore what happens to landforms over time. Today, the students discovered that when a river flows over a plateau (for many, many, many years) it creates a canyon and a delta.
We did a fun, team-building experiment with play-doh where we saw if the play-doh gained weight, lost weight, or stayed the same if we built a centipede with the play-doh. We found that after we built the centipede it weighed half of a gram more than it started. It may have been human error that caused the weight to change. We learned that matter cannot be destroyed and the weight of the starting material should stay the same throughout the experiment. The weight of the ending material should be the same as the weight of the beginning material.We have been discussing the scientific method and how to design science experiments. We conducted a few experiments twice in order to see how changing one variable sometimes changes the entire outcome. What was your favorite experiment we did last week? |
