 In this lesson, we are going to introduce the students to the idea of polymers. The key knowledge behind the lesson contains of three points: 1. Definition of Polymers; 2. Example of Polymers; 3. Properties of Polymers formed depends on the starting material. To explore the topic, we are going to make our own polymer bouncy ball from scratch. After the bouncy ball is created, we will ask the students to observe the properties of the bouncy ball.

 In this lesson, we are going to introduce the students with the science behind magnets and compasses. The key problem is, how do compasses work? We will construct a compass of our own with the students. Through observing the behavior of the compass, we will present the idea of earth's magnetic filed, the idea of how magnets can be magnetic, etc. 
 In this lesson, we are going to introduce the students to the science behind another everyday item - detergents. To present the whole picture of detergents to the students, we are going to use three seperate experiments: 1. Mixture of oil and water with detergents as intermediary. (As presented in the 'if mixing is urgent' PDF) 2. The movement of color in mild.(As presented in the 'On the Mooove' pdf) 3. Testing Water's Skin. The three experiments above will each present the characteristics of detergents and some practical issue or usage of them other than cleansing.
 In this lesson, we are going to introduce the students to the science behind Crime Scene Investigation (CSI). We are going to roleplay with the students impostering ourselves as crime scene investigator. The lesson is divided into 3 parts: 1. Fingerprints; 2. Identifying Unknown Substances; 3. Genetic Analysis of DNA. According to the time limits of your own, you can choose either part 1 or part 2 to conduct first, but make sure get to part 3. After each part, the students should come up with their idea of who the suspect is, part 1 and part 2 will supposedly produce contradictory results but part 3 will be the definite prove of guilty.
 In this lesson, we are going to introduce the students to the principles behind freezing. More specifically, we are going to introduce the students to the idea of freezing with 3 focus:
 In this lesson, we are going to introduce the students to the chemistry behind the foods that we eat everyday. There are several key points in this lesson:
 In this lesson, we are going to introduce the students to the idea of solubility. We are going to explore the topic starting from daily examples such as how do you clean oil or salt. Then introduce the idea of dissolve, the definition of solute and solvent to the students. Furthermore, we are going to talk briefly about the molecular principles behind different material's dissolving. The lesson is composed of four experiments: 1. What does it mean to dissolve? 2. Solubility of liquids; 3. Solubility of solids into liquids; 4. How do you wash oil from your hands?
 In this quarter, we are explore the physical and chemical world with the students. This week, we are going to introduce the students to the idea of chromatography - the method scientist used to isolate desired chemicals from mixtures. To explore the topic, we divided the lesson into two major parts:
