Hello scientist! Today we will learn about mixtures, solutions, and how to define new words.
A mixture combines two or more things. You can easily see and separate the parts in trail mix.
A solution is a special mixture. Context clues in a sentence help you find the meaning of new words.
Check a digital dictionary for dis·solve. It has two syllables: dis-solve. It means to mix completely.
In a solution, one substance spreads evenly through another. You can no longer see the separate parts.
✏️ Worked example
Read this sentence: 'The sugar will dissolve quickly in hot tea.' Use dictionary tools and context clues to explain what dissolve means.
- Look at context clues in the sentence. Sugar goes into warm tea and seems to disappear.
- Check a digital glossary for pronunciation and syllabication: dis·solve (dih-ZOLV).
- Read the glossary entry to find the correct meaning: to mix evenly into a liquid.
- Combine clues and the definition. Dissolve means the sugar breaks down and mixes fully into the tea.
