Year 2 Chemical Science

Let’s get mixing!

Phase Lesson OverviewEngage Lesson 1: Week 1

Exploring mixtures. Children’s ideas about mixtures.

The purpose of this lesson is to capture students’ interest and curiosity about materials and mixtures. To discover the students’ ideas and conceptions about mixtures. Students will be asked to categorise items as mixtures or non-mixtures. Students will also be asked what a mixture is and to draw a picture of a mixture and write what it is, what is it used for and who makes it.

Explore Lesson 2: Week 2 Mixtures in the Kitchen.

Lesson 3: Week 2T&E‘Crew Stew’

Lesson 4: Week 3Let’s add Water

This lesson is designed to provide experience with solid and solid mixtures and an introduction to solid– liquid mixtures. This lesson uses food products as this is where many students have previous experience with mixing. During the early part of the lesson students will make different mixtures with the ingredients and attempt to separate them. To end this lesson students will assist the teacher make muesli and chocolate crackles.

The students are studying a series of books on Pirates. This week the students will have been reading a book called ‘Crew Stew’ by Lisa Thompson (2007). In this book a stew is made from tomato, potato, onion, carrot and a salty sea sock. In the T&E lesson the students will make this stew replacing the sock with sock shaped bacon. Students will produce a Power point presentation.

In this lesson the students will investigate what happens when water is added to several of materials. This involves making solid-liquid mixtures, liquid-liquid mixtures and solutions. Students experience uses of mixtures outside the kitchen – glue and bubble mixture.The students will study the grapheme ue as in glue this week. These mixtures will be left for the water to evaporate and students will observe them at the start of the next Science lesson.

Explain Lesson 5: Week 4We’re not mixed up about mixtures!

Students will observe the mixtures from last week’s ‘Let’s add Water Lesson’. Students will view an interactive whiteboard presentation of the work they have done in this unit so far. Students will be explicitly taught the scientific definition of a mixture. Students will create a Power point presentation about mixtures.

Elaborate Lesson 6: Week 5Pirate Soup – Oops!

Lesson 7: Week 6Recycling Paper

The students will be asked to make Pirate Soup. Oops the pirates have already had lunch on the island. The students will have to predict and plan how to separate the items in soup. The students then test and evaluate their plan.

The students will look at how mixtures can be used to remake waste paper into new paper.

Evaluate Lesson 8: Week 7

Lesson 9: Week 8

Review previous lessons on mixtures and combining materials by viewing an interactive whiteboard presentation. EVALUATE student learning using worksheets and making a class book.

Students will learn about ochre pigments used by the Aboriginal people. Students will mix ochre with water to make paint. The students will paint a picture using the ochre paint which tells the story of their learning journey in Science this term.

Students will:

1. Students are to ‘think, pair, share’ what mixtures are and what examples they can think of. Following this students’ will participate in a short class discussion of what mixtures are and provide examples of mixtures they know.

2. Students (in pairs) will move around ‘stations’ and observe and ‘play’ with several items that are mixtures and non-mixtures. There will be one interview station where the pairs video their partner answering the question ‘What is a mixture’. Students will move around as many stations that time permits. In their pairs students will observe items, they will discuss whether they believe they are mixtures or not and give reasons for their classification.

3. Individually students are required to draw a picture of a mixture. The students are to write what the mixture is, what it is used for and who makes it. The students will use the ‘My Mixture’ worksheet.

Items for mixture and non-mixture classification:

Packet cake mix Sugar Muesli Rice bubbles Paint Clag glue Water Cordial Sand Sand and gravel

Disposable plastic bowls, plastic spoons and magnifying glasses for students to use to investigate their items.

Interactive whiteboard (IWB) (or large butcher’s type paper if an IWB is unavailable) to record students’ initial ideas of mixtures and their classifications of the items with their reasoning.

Classification table. Worksheet.Worksheet ‘My Mixture’See Resources Appendix 1

1. Think, Pair, Share / Group Discussion - Think, Pair and Share followed by a class discussion on the topic. The purpose of this activity is to ‘switch the students’ brains onto the topic’ and give them time to think about what a mixture is before attempting the classification. Individual, pairs and whole class.

2. Classification - Students will observe the items and discuss and classify in their pairs. Small group.

3. Drawing and Independent Writing - Students are required to complete a drawing and explanation of a mixture individually. Teacher is to read through the requirements of the worksheet with the class. Individual

Differentiation: Student with low literacy skills is to have teacher assistance with the ‘My Mixture’ worksheet to record his/her answers about their mixture. Teacher is to write the student’s answers on an extra worksheet and read back to the student while pointing to each word. Student is then to copy onto their own worksheet.

Mix and Match book about mixtures. This activity provides another opportunity for students to demonstrate their knowledge of mixtures. In this activity the students are producing a page that will become part of a book. The students will draw and write short text for this page. The students will share their page with a partner. Individual and small group.

The book will be produced in the classroom during this lesson. This is so that the students can see their completed work and so that they can have fun looking through it and seeing combinations that still make sense and others that are nonsense. Whole class.



View the presentation of their learning journey.

Participate in a class discussion about their learning journey.

Read their page to a partner. View and comment on the class book.


Use appropriate vocabulary to describe the materials and mixtures.

Writing:Students demonstrate writing capabilities when they:Provide written descriptions of why they chose the materials they used to make their pirate ship.Provide a written definition of a mixture.Provide text to for their page in the class book on mixtures.

Differentiation: Student with low literacy skills is to have teacher assistance with the writing involved for the worksheets. For this lesson the teacher is to transcribe the student’s answers on to the worksheets.
