Investigating Light in Grade 1

As part of our How the World Works unit of inquiry, the grade 1 students have been investigating into questions such as "How Does Light Travel?",  "What is Darkness?" and "What Materials Can Light Travel Through?"

The students have been conducting experiments just like real scientists. They have been posing questions, predicting what they think will happen, observing, recording their findings and reflecting on what they have learnt from the experiments. The students have also been learning about what is a fair test and why this is important when conducting an experiment. 

In the "How Does Light Travel?" experiment the girls used 3 cardboard pieces with a hole cut into them to back a tunnel. They then shone a light through the tunnel to see what they noticed. For the second part of the experiment they moved a part of the tunnel to observe what happened to the light. 

During our most recent experiment the students were testing how light travels though various materials. They learnt some new vocabulary words such as transparent (light travels through like in a window), translucent (some light comes through) and opaque (no light comes through). At the beginning of the experiment the students made predictions about what materials would be transparent, translucent or opaque and then carried out a fair test to check each material. 

Listen to Mihika explain her findings about some of the materials she tested. 

Watch Magdalene reflect on her findings after she completed her fair test. 

Check out Kokoro and Hayoon's recording sheets below where they have made great predictions and even better reflections about the materials and how light travels through them after conducting the experiment.
