Standard: 2.NS.1.1- Observe, describe and measure ways in which the properties of a sample of water (including volume) change or stay the same as the water is heated and cooled and then transformed into different states. Extensions: Students can graph the weight of the sponge over time on a line graph. Students can discuss their predicitions and/or inferences (depending on how familiar they are with the water cycle) as a class. This activity is a good segwey into concepts such as the water cycle, evaporation, and states of matter. Adaptations: ELL students benefit from the whole class discussion stemming from the single experiement performed at the front of the class. Students gain a better idea of what is going on as they listen to each others' predictions and inferences as to where the water is going if it is leaving the sponge.

Standard: 4.2.2

Expansion: have students make predictions about what will happen to the solution and then record changes in crystal formations as they grow.  Have student check their prediction to see whether it was accurate. 

ESL: practice writing observational notes will reinforce vocabulary and writing skills.
