Day 1: Objective: Students will understand that solids and liquids mix with water in different ways. - Begin the lesson by asking students to brainstorm different materials that they think will mix with water. - Discuss their ideas as a class and create a list on the board. - Introduce the concept of dissolving and explain that it is when a substance is distributed evenly throughout another substance. - Conduct a simple experiment where students mix different materials with water and observe how they interact. - Have students record their observations and discuss as a class.

Day 2: Objective: Students will be able to classify liquids based on their ability to mix with water. - Review the concept of dissolving from the previous lesson. - Provide students with a variety of liquids and have them predict whether each liquid will mix with water or not. - Conduct an experiment where students mix each liquid with water and observe the results. - Have students record their observations and classify each liquid as either mixing or not mixing with water. - Discuss their findings as a class and compare their predictions to the actual results.

Day 3: Objective: Students will plan and conduct an investigation to identify liquid materials that will mix with water. - Review the concept of dissolving and classifying liquids from the previous lessons. - Explain to students that they will be conducting their own investigation to identify liquid materials that will mix with water. - Provide students with a variety of liquid materials and have them plan and conduct their own experiments. - Instruct students to record their observations and classify each liquid as either mixing or not mixing with water. - Have students share their findings with the class and discuss any patterns or trends they noticed.

Day 4: Objective: Students will understand that some solids will dissolve in water while others will not. - Begin the lesson by asking students to brainstorm different solids that they think will dissolve in water. - Discuss their ideas as a class and create a list on the board. - Introduce the concept of dissolving solids in water and explain that some solids will break down into smaller pieces that cannot be seen. - Conduct a simple experiment where students dissolve different solids in water and observe the results. - Have students record their observations and discuss as a class.

Day 5: Objective: Students will be able to classify solids based on their ability to dissolve in water. - Review the concept of dissolving solids from the previous lesson. - Provide students with a variety of solids and have them predict whether each solid will dissolve in water or not. - Conduct an experiment where students dissolve each solid in water and observe the results. - Have students record their observations and classify each solid as either dissolving or not dissolving in water. - Discuss their findings as a class and compare their predictions to the actual results.

Day 6: Objective: Students will plan and conduct an investigation to determine solids that will dissolve in water. - Review the concept of dissolving solids and classifying solids from the previous lessons. - Explain to students that they will be conducting their own investigation to determine solids that will dissolve in water. - Provide students with a variety of solid materials and have them plan and conduct their own experiments. - Instruct students to record their observations and classify each solid as either dissolving or not dissolving in water. - Have students share their findings with the class and discuss any patterns or trends they noticed.

Day 7: Objective: Students will understand that substances dissolve faster in hot water than in cold water. - Begin the lesson by asking students if they have ever noticed that substances dissolve faster in hot water. - Discuss their observations as a class and introduce the concept of water temperature affecting the dissolving process. - Conduct a simple experiment where students dissolve the same solid in both hot and cold water and observe the results. - Have students record their observations and discuss as a class.

Day 8: Objective: Students will be able to plan and conduct an investigation to determine the effect of water temperature on the dissolving of a solid. - Review the concept of water temperature affecting the dissolving process from the previous lesson. - Explain to students that they will be conducting their own investigation to determine the effect of water temperature on the dissolving of a solid. - Provide students with the same solid material and have them plan and conduct their own experiments using both hot and cold water. - Instruct students to record their observations and compare the rate of dissolving in hot and cold water. - Have students share their findings with the class and discuss any patterns or trends they noticed.

Day 9: Objective: Review and reinforce concepts learned throughout the unit. - Conduct a review activity where students are given different scenarios and have to determine whether a substance will mix or dissolve in water based on their knowledge from the unit. - Discuss the correct answers as a class and address any misconceptions or questions.

Day 10: Objective: Assessment of student understanding. - Administer a written assessment where students are asked to classify different materials as either mixing or dissolving in water. - Review and discuss the assessment as a class, addressing any areas of confusion or misunderstanding.
