A Solid Investigation
Students will be able to investigate, describe, and record information about solids.
- Explain to the students that they will learn about solids today.
- Tell the students that there are three states of matter: solids, liquids, and gases. Tell them that their focus today will be on solids.
- Show Matter Chatter to the students.
- While the song is playing, write the world "solid" on chart paper or the board to make a word web.
- After the song, ask students to give examples and characteristics of solids.
- Write down the words and phrases the students say on the word web.
Explicit Instruction/Teacher modeling(10 minutes)
- Bring the students together and tell them that you will show them how to investigate a solid.
- Pick a solid in your classroom of your choice and demonstrate for the students how you investigate a solid, and then describe to the students what you found, answering the questions that are found on the Solids Investigation worksheet.
- Write down your answers on a piece of chart paper to be an example for the students when they do their own investigation.
Guided Practice(10 minutes)
- Ask some students to demonstrate for the class how they can investigate a solid.
- Give the student a solid object, and guide them to answer the questions you will be asking today.
- Explain to the students that they will all now work on investigating solids.
- Send the students back to their desks.
Independent working time(15 minutes)
- Hand out the bags of solids and worksheets to the students.
- Hand out the nails and remind the students that they are for scratching the objects only.
- Tell the students to begin their investigation and encourage them to talk and share with their friends while working.
- Walk around and ask students questions about their discoveries.
- When finished, ask the students to put every object back in the bags, then collect them and the nails.
- Enrichment: To challenge students, you can have students write a paragraph about a solid. They can create a description without saying what the object is, and other students have to guess what it is.
- Support: If students have difficulty writing, you can have them orally communicate their discoveries about solids.
- During the investigation, walk around and listen to student conversations and ask them about their discoveries.
- Look over student worksheets to check for understanding.
Review and closing(10 minutes)
