Checkpoint 1 |
Weekly Summary:
This week, we looked at different materials that would be found at various stations in the lab. We used the scientific method (observe, question, predict, investigate, conclude) to develop different relationships that could be investigated at these stations based on the different properties of these materials.

Quiz Directions:
- Look at the picture of the cylinders below. Imagine that these cylinders have different weights when you pick them up; the lightest one (A) is on the left and the heaviest one (E) is on the right.
- Assuming these materials were set out at a lab station for you, I want you to set up some potential labs that could be done (like we did in class).

This week, we discussed the introduction labs and specifically focused on the graphs. The key points mentioned in the discussion were:
- Writing equations in terms of the graph by substituting in more meaningful variables than "y" and "x"
- The meaning of the slope of a linear graph using a "for every/each..." statement
- The units of slope (rise/run)
- The meaning of the vertical intercept
- How to determine if the vertical intercept of a graph is significant using the 5% rule

Weekly Summary:
This week, we practiced making velocity-time graphs from other representations of motion (position-time graphs, motion maps, written descriptions). We also used Logger Pro and motion sensors to check if our predictions were correct. The key points mentioned were:
Quiz Directions:
Match the correct v-t graph shown below to the correct description. Each choice will be used only once.
This week, we practiced making velocity-time graphs from other representations of motion (position-time graphs, motion maps, written descriptions). We also used Logger Pro and motion sensors to check if our predictions were correct. The key points mentioned were:
- Looking at the slope of a p-t graph to determine the velocity
- Sketching what the given velocity would look like on a v-t graph
- Movement away from the reference position (or motion sensor) means the object is moving in the positive direction
- Movement toward the reference position (or motion sensor) means the object is moving in the negative direction

Match the correct v-t graph shown below to the correct description. Each choice will be used only once.
