Temperature and Particles

We continued in our They Made a Difference unit in grade 3 by talking about how Fahrenheit and Celsius made a difference in how we describe temperature. Students made their own thermometers that showed how particles take up more space as they warm up. Students also conducted an investigation about how a vitamin tablet dissolves faster in warmer water because the particles more around more. 

To make this a fair test we only changed the temperature of the water. We used the same type of beaker, the same amount of water and the same size tablet. 

We used thermometers to measure temperature and ipads to measure time in this experiment. 

As the water warmed up, it moved up the glass rod.
