Standard: 2.1.1, 2.NS.2

Expansion: Have student record their observations of the changes of state in a notebook. 

ESL: Use of a notebook for recording, and peer work within a classroom will help ESL students reinforce vocabulary and language through communication. 

Standards: 1.1.2, 1.1.3

Expansion: The maple syrup part of this will be a little difficult with a stove in a classroom, but experiment with different types of liquids or solids.  Salt-water might be an interesting long-term experiment for changing a liquid to a solid.  That, or be very cautious how this is done. 

ESL: Recording findings will help students reinforce science writing skills. 

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: 5.DP.1 - Describe the weight and volume and measure the weight and volume of various objects.(5.1.1, 5.1.2) Demonstrate that mass is conserved even when a substance has undergone a change in its state. (5.1.3, 5.1.4)

Extension: Students could weigh the materials seperately before combining into the slime mixture and compare and contrast the weight with after the slime has been created. Students could hypothesize where some of the mass was relocated (assuming some moisture was worked out of slime while handling).

Adaptation: Students could make homemade ice cream, and other baked goods to demonstrate the difference between chemical and physical changes.

Standard 6.NS.1 - Understand that the properties and behavior of matter can be explained by a model that depicts particles representing atoms or molecules in motion. Extension: Once students understand properties of different liquids, they can think how to manipulate those liquids and their properties. One example would be to heat up one liquid to several different temperatures and see how they interact. Adaptation: Teacher could split students into groups of 3-4 and have them stack liquids on their own. Students could bring in several liquids from home (all approved) and try stacking them based on the observed properties.
