3rd grade 19 TAC §112.5 45 student expectations 8 activities

3rd grade Science

Third graders measure and classify matter, explore forces including gravity and magnetism, trace energy and its effects, learn what changes Earth's surface quickly and slowly, look at natural resources, and describe how organisms depend on each other in ecosystems.

Practice activities

🧲Matter and Forces LabSolids, liquids, gases, heating, cooling, gravity, and magnets.
🧪Matter LabSink or float, magnets, states of matter, heating and cooling.
🧊Conveyor Sort: Solid, Liquid or GasA solid keeps its shape. A liquid and a gas take the shape of their container.
🪐Energy and the Solar SystemLight, sound, thermal, and mechanical energy; speed and energy; how position changes; Sun, Earth, and Moon; the planets in order.
🔭Sky Watch: Orbits & PlanetsWho orbits whom, and the planets in order.
🌋Earth, Resources, and Life CyclesWeather in different places, how soil forms, volcanoes and earthquakes, using and conserving resources, animal structures, and life cycles.
🦴Seasons, Food Chains, and FossilsHow weather changes animal behavior, what happens when a food chain breaks, and what fossils tell us.
🕸️Food Web Builder: Energy FlowFollow the Sun’s energy, and predict what happens when frogs or bees are gone.

How to help at home

Ask for predictions before an experiment, then talk about whether they were right.
Sort household objects by what a magnet picks up.
Track the weather or the Moon for a week on paper and look for the pattern.
