Each day students are expected to write one thing they learned and one question they still have, in their science journals. The teacher reads their entries to determine the effectiveness of the activities and what students understand. This is an example of:

Formative assessment.

Explanation:

Formative assessments guide teachers to recognize topics that students are unable to grasp, skills that they have trouble gaining, or performance goals that they have not yet met so that changes can be made to classes, teaching strategies, and instructional support. It function as a lesson for students, much like a practical homework assignment. They evaluate for comprehension along the way and direct teacher decision-making on future instruction, we also give guidance to students so that they can enhance their results.

a. formula: f=ma or f/m=a

10,000n/1,267kg≈7.9m/

b. formula: a= and s=d/t

speed= 394.6/15

s=26.3m/s

a=

a=1.75m/

c. 7.9-1.75=difference of 6.15m/

d. the force that most likely caused this difference is friction forces

  b.

there are isolated pockets of farming, generally around rivers and oases, which are used for irrigation.
