Download lesson plan
Grade Subject

Students will be able to investigate, describe, and record information about solids.

(10 minutes)
  • 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.
(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.
(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.
(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.
(5 minutes)
  • During the investigation, walk around and listen to student conversations and ask them about their discoveries.
  • Look over student worksheets to check for understanding.
(10 minutes)
  • Bring the students together with their worksheets.
  • Ask the students to share with the class their discoveries about the solids they investigated.
  • Discuss any differences in answers.
