What your child will learn
Matter is made of particles
- What Is Matter?Define matter as anything that has mass and takes up space.
- Particles Too Small to SeeExplain that all matter is made of particles too small to be seen.
- Evidence of Invisible AirUse evidence like inflating a balloon to show that air is matter made of tiny particles.
- Where Did the Sugar Go?Use a model of particles to explain why sugar seems to disappear when stirred into water.
- Solids, Liquids and GasesDescribe how particles are arranged and move in solids, liquids and gases.
- Tiny Particles Review ReviewReview how models of tiny particles explain the behavior of solids, liquids, gases and dissolving.
Properties of matter
- Color, Hardness and TextureDescribe materials by observable properties such as color, hardness and texture.
- Conductors and InsulatorsTest and classify materials by whether they conduct heat or electricity.
- Is It Magnetic?Identify materials by whether they are attracted to a magnet.
- Does It Dissolve?Test and describe whether a material dissolves in water.
- Properties of Matter Review ReviewReview how materials are described and sorted by their properties.
Identifying mystery materials
- Measuring Mass and VolumeMeasure the mass and volume of materials using a balance and a graduated cylinder.
- Shiny, Stretchy and MoreObserve properties such as reflectivity and elasticity to tell materials apart.
- The Mystery White PowderPlan a set of tests to identify an unknown white powder.
- Choosing the Right MaterialUse material properties to choose the best material for a design problem.
- Mystery Materials Review ReviewReview how measuring properties helps identify materials and choose them for designs.
- Unit 1 Test: Matter and Its PropertiesShow what you learned in the whole unit (Matter is made of particles, Properties of matter, Identifying mystery materials) by answering mixed questions.
Try a question from this unit
From the lesson “What Is Matter?”
Which of these is matter?
Show the answer
The air inside a balloon. The air inside a balloon has mass and takes up space, which is why the balloon puffs up. Light, sound and thoughts are not matter.
Hint kids see after a wrong try: “Look for the one that has mass and fills up space.”
