���� JFIF �� C They will time their cars and calculate how fast the car traveled. valuate students' Understanding of the Concept. If your dragster does not meet specifications, it may not op-erate properly. Make sure your design does not cut into or too close to the engine housing. Your mission is to create the fastest animal on 4 wheels! The will compare their own results to that of their classmates to make a conclusion about how weight and drag affect speed.

I want a minimum of 8 design sketches. Dragster C goes further than dragster B due to the larger circumference of the bigger tires, and even though axle speed is the same. 09. Only after students have explored the concept are they able to use the terms to describe what they have experienced, and they begin to examine mentally how their explanation fits with what they already know. <> Please include your reasons for designs (weight, aerodynamics, etc), Once your booklets are complete and your final design has been approved you will receive your materials to get started.

Printed on 11" x 17" white bond paper. You will also have to create a paper template for cutting (top and side views), ​http://www.science-of-speed.com/STEM_Learning/. By discussing their ideas with others, students can construct a deeper understanding of the concepts. The students will then run (race) their cars on a 60 foot raceway. The CO2 cartridge is punctured so the compressed gas can rapidly leave the canister causing the dragster to move. �q`�n,1h����S�׍�=���O�>k�}=�>��}�>+�_s���k|kt���n��7��>�����_#��u���d, X�M�YÑW'h��Ú �12�J�%p&��!b1�H\ D�U$M P��H�l �1bg,0�Q�R"�j���!�N+���)����u�{�1�}x���㽮���c�Y�1t�wW�k��o���2������z���������SJ��_�v�����_�gК��(J�b!b-d,B�,`����J�"hMjG����c\ �!BA �A*� �4$�"r��f�1FY0�l2l�|��>������İ�Eŕ���,�Qi�o7軃�߫���b��/.� ��N�k6��>���>_�} ���j%\�9�G���,B��b��8sC4gbJ��B�,DАB���� �B&�0� �q�4�����zM'��z�G��A�G�rP �/���e�!��e�ڝ���辋������G�_��T|��5�n�M���o�Ŏ� �촋���{�v>���m�O���~��+����}S�Q�]S�&/�~����/��b�Dz| ~����)�/��?B���}�~;�Sx.��M �c,������p�b4�",aP�c,�\������ ��H\/��y�q��4�4�����N�H� 2����u�q��y��.

Students will successfully explain how their dragster demonstrated (proved) Newton’s Second Law. They will understand that weight affect speed which is essentially Newton’s Second Law and that drag resist motion which also effects speed. They will test for wind drag, measure the weight of their cars. Create your own unique website with customizable templates. The more tire mass and the bigger the tire circumference, the further the dragster … At the conclusion of the racing the students will analyze their cars weight and speed, and their cars drag speed. In this write up the students will have to explain how Newton’s Second Law was demonstrated through this activity and also explain the affect drag had on the performance of their car. Interaction between the students is essential during the elaboration stage. Work through and follow the instructions asked of you. The goal of the unit is to allow students apply concepts from physics with real world application. Students will complete worksheet. ��p�"�!b `�� ��$.
