Focus Question: How can you make 10-minute ice cream? and How do atoms combine to make new substances? 

 

Students will take what they have learned about solutions and phase changes to make 10-minute ice cream. Then students will review chemical formulas as symbolic representations for substances and learn that the fundamental building blocks of substances are atoms. Chemical bonds are introduced as the attractive forces holding particles together. 

 

IMPORTANT DATE:

- Zoom Meetings at 10 am Thursday, June 4

 

 

Students will heat three materials and will observe the results. They will observe the change of state from liquid to solid and discover that the materials melt at different temperatures. In the second session, students will use candles to increase the energy transferred to wax and sugar. They will observe that both wax and sugar change from solid to liquid when heated with a candle, and return to solid when the flame is removed. Students will use this experience to extend their understanding of melting and to reinforce the idea that different substances melt and freeze and different temperatures. 

 

IMPORTANT DATES:

 

Focus Question: What is the difference between dissolving and melting? and Do all substances form solutions in water?  

 

Students will begin by expressing their understanding of dissolving and melting. Then they will observe what happens to four candy-coated chocolate pieces in four different environments: hot water, hot air, cold water, and cold air. Based on their observations of the different outcomes, they will generate definitions for the terms dissolving and melting. In the second investigation, students will make two aqueous mixtures to test solubility. 

 

IMPORTANT DATES:

 

 

Students will measure their pulse under different circumstances. They will use the pulse rate to calculate frequency and consider repeating patterns.  

 

 

 

 

Students will use their understanding of energy transfer to face an engineering problem: how to build a container that keeps hot liquids hot and cold liquids cold. They will test materials for their insulating properties in preparation for the design challenge. 

 

- Investigation 6 quiz (AFL)- group A: 3/20 and group B: 3/23

- IAR testing 3/24- 3/26

 

 

Students will be introduced to the calorie as a unit of energy transfer. They will conduct a water-mixing investigation and use the results to calculate the number of calories transferred from hot to cold water during the interaction. The numbers should be equal, supporting the notion of conservation of energy. Group A will take a quiz on Monday and then both groups will move onto prepare for the investigation test by completing a study guide. They will be assessed by the end of the week.

 

- Investigation 5 quiz (AFL)- group A: 3/3 

- Investigation 5 Study Guide (AFL)- group A: 3/4 and group B: 3/3

- Investigation 5 test (AOL) and Journal Check (AFL)- group A: 3/6 and group B: 3/5

- Illinois Science Assessment (ISA)- 3/9- 3/12

 

 

Students will  explore the concept of energy transfer as a consequence of collisions between particles. They will engage in group discussions, water animations, and participate in structured reading. They will be introduced to temperature as the average kinetic energy. 

 

- Chicago River Student Congress (extra credit)- 2/29 8 am- 1 pm

- Investigation 5 quiz (AFL)- group A: 3/2 and group B: 3/3 

- Investigation 5 Study Guide (AFL)- group A: 3/4 and group B: 3/5

- Investigation 5 test (AOL) and Journal Check (AFL)- group A: 3/6 and group B: 3/9

 

 

Students will begin the week by taking a test on Investigation 4- Kinetic Energy, and then we will move onto the next investigation on Energy Transfer. Students will call on their knowledge of mixing hot and cold liquids to predict he final temperature of a mixture of equal masses of hot and cold water. They will conduct the activity and use their results to determine an algorithm for calculating final temperatures.
