Are you doing a Solids and Liquids unit this year? Here’s a great lesson to get things started!
Intro Lesson: Liquids and Solids
Objective: The purpose of this lesson is to introduce the idea of solids and liquids, introduce the concept of observations, and to create excitement for the students about this unit.
Hook: Bring out a popsicle
Introduction to Solids and Liquids:
Ask the following questions to evoke discussion on solids and liquids:
- What do I have here?
- Is this a solid object? What do you think I mean by solid? Can anyone take a guess?
- What makes it a solid object? Why would you say it is a solid object?
- What would happen if I just sat it down in this dish for any hour? Or if I put it next to a window?
- Would it still be a solid? What would you call it then?
- So in one state it is a solid, but when left out to warm up, it starts to melt and become a liquid.
Explain that we are starting a new subject in Science. We are going to be looking at all sorts of solids and liquids
Introduction to Observation:
Explain that we are going to be doing a lot of observing over the next month.
Ask if anyone knows what observing means.
It is using our five senses to examine and make comments on an object and write those comments down. Observation includes all fives senses.
Bring out Chart of 5 Senses.
Give everyone a popsicle to eat.
Explain to the students that they need to use their:
Eyes – what do they see?
Ears – what do they hear?
Nose – what does it smell like?
Touch – What does it feel like? Is it heavy?
Taste – What does it taste like?
Discuss these as a group
Explain that the students now have a chance to observing different items.
You will be dividing class into groups. Each group will visit each station. At each station there will be an object to observe. Write down your observations on the chart paper. You then move to the next stations and have to add NEW information to the list of observation on the chart paper.
Station 1: Pop
Station 2: Apple
Station 3: Cloves
Station 4: Orange Juice
Station 5: Plasticine
Station 6: Raisins
- Break class into science groups. Have objects to observe around classroom with chart paper and marker. Let them go.
- Clean up
- Re-group debrief
- Was it difficult to come up with observations?
- Which of your five senses was the easiest to do the describing
- What are some words that you used to describe the objects
- Explain that students will be asked to do observing many times over the next three weeks. Keep you 5 senses in mind and make sure you record down your thoughts.
