Theoretical material for the lesson, definitions for concepts 

Motion in One Dimension

                                     

     vf = vi + aDt          Dd = ½ (vf + vi) Dt          Dd = viDt + ½ aDt2          vf2 = vi2 + 2aDd

 

Two-Dimensional Motion & Vectors:

 

     Ddx = vixDt            Ddy = viyt + ½ aDt2            vfy = viy + aDt           vfy2 = viy2 + 2aDdy         

 

 Forces & the Laws of Motion:

 

     FNET = ma          W = mg          f = mN

 

Work & Energy:

 

     Wk =  FDd (cos q)          KE = ½ mv2          Wk = DKE          PEgravitational = mgh         

     PEelastic = ½ kx2          

 Momentum & Collisions:

 

     p = mv          FDt = Dp = mDv

 

Rotational Motion & the Law of Gravity:

                                     at = ra        

     wf = wi + aDt          Dq = ½ (wf + wi)Dt          Dq = wiDt + ½ aDt2          wf2 = wi2 + 2aDq

                                                  

                                    (Universal constant:  G = 6.67 x 10–11 Nm2/kg2)

Rotational Equilibrium & Dynamics:

 

     t = rF (sin q)          tNET = Ia          L = Iw          KErotational = ½ Iw2

                         

Fluid Mechanics:

               FB = Wdisplaced fluid = mfluidg                              

     A1v1 = A2v2         P + ½ rv2 + rgh = constant          PV = NkBT = nRT

 

Additional guidelines for organizing a lesson 

Students can deduce topic of the lessen and objectives, for clarification you can show topic and the learning objectives on the presentation.

Then Subject-specific vocabulary & terminology will be presented to the students and their activities during the research work will be explained.

Then teacher will give the worksheet on the concepts studied previously. Students attempt the questions in groups as they engage in discussion. The teacher helps the learners with difficulties in answering the questions.

Reinforce the LO’s: answer any questions students may have/clarify understanding. Students reflect on their learning. 

At the end of the lesson teacher will give homework.

Additional multilevel (on differentiation) tasks

Each chapter has extra tasks which you would use for high level students.

Recommendations for formative assessment

 

1)      Use the answers provided to assess students’ understanding and the manner of application of the all terms concept knowledge

2)      Provide a general feedback for every given point (pay attention to give a fully explained feedback to the points that were not given)

3)      You can change the numbers in calculations according to the student’s ability
