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.

Standards: 6.NS.2, 6.NS.3, 6.NS.4, 6.NS.5

Expansion: In order to cover several other Nature of Science, students could be required to make predictions, record their results in a log, test their predictions through multiple tries, and then analyze the results.  

ESL: Students would be able to practice using the American standard measuring system with cooking, and have that reinforced.  

Standards: 2.DP.2 - Day to day and over the seasons, observe, measure, record and recognize patterns and ask questions about features of weather. (2.2.1, 2.2.2, 2.2.3, 2.2.4, 2.2.5, 2.2.6) Investigate how the position of the sun and moon and the shape of the moon change in observable patterns. (2.2.7, 2.2.8, 2.2.9)

Extension: Students could use this activity as a stepping stone to study the phases of the moon in greater depth. The next step could be to model the changes of the moon as it rotates the earth by using a flashlight as the sun.

Adaptation: This is a great physical representation to descripe words that may have no meaning to ELL students. Students are more likely to remember the phases because there is food involved and it was studied in a casual setting.

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: 2.1.1, 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. 

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.

K.NS.3 - Observe living organisms, compare and contrast their characteristics, and ask questions about them

1.NS.3 - Describe objects in terms of the materials that compose them and in terms of their physical properties

2.NS.3 - Observe, ask questions about and describe how organisms change their forms and behaviors during their life cycles
