What is a Newton?

Learning about force with interactive models. 

Laboratory in the classroom is a crucial means of instruction in science. Laboratory activities are essential because it provides training in observation, data collection, and evoked students’ interests.

There are several objectives that can be achieved in laboratory activities such as skills in manipulation, inquiry, investigation, organization, and communication. In addition, certain attitudes may also be developed such as curiosity, interest, risk taking, objectivity, precision, confidence, responsibility, collaboration, and liking science.

For my class, the students shown below are working on a laboratory activity that introduces the unit Newton, a unit for force. In this investigation, they will explore the precise definition of force and measure the strength of force. 

The fourth period physical science class working on friction lab by collecting data and running the experiment. 

There was also a second part to the laboratory activity mentioned earlier. This time, the students are to explore the different effects of friction, also a type of force.

In the laboratory activities mentioned above, the students learned how to collect time through a device called a photogate. They also learned how to set up the straight tracks that they needed in order to accomplish the tasks given to them. On top of that, the students learned to collect and properly organize their data in a table and a graph using Google sheets.

Setting up laboratory activities can be tedious and taxing but adding this to science instruction is essential because it promotes extended learning for students. Therefore, adding laboratory time during class is good but adding more must be better.
