Match each planet to its distinct characteristics: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
Read each stage description. Write the name of the plant life cycle stage.
Classify everyday substances into solid, liquid, or gas based on shape, volume, and molecular arrangement.
Connect animals to their natural living environments and identify survival adaptations.
Read each problem carefully. Write your answers clearly in the spaces provided. Check your work using the answer key.
Read each problem carefully. Write your answers clearly in the spaces provided. Check your work using the answer key.
Associate sight, hearing, smell, taste, and touch with their respective sensory organs.
Determine whether items are living (grow, need food/water) or non-living (do not grow).
Classify everyday devices into the six simple machines: lever, pulley, wheel & axle, inclined plane, wedge, and screw.
Investigate closed vs. open electrical circuits, switches, batteries, and classify materials as conductors or insulators.
Distinguish between weathering (breaking rock), erosion (moving rock), and deposition (dropping sediment).
Trace energy flow from sunlight through producers (plants), primary consumers (herbivores), and apex predators.
Investigate interactions between the Geosphere (rock/soil), Hydrosphere (water), Atmosphere (air), and Biosphere (life).
Write scientific explanations connecting experimental data (Evidence) to hypotheses using scientific principles (Reasoning).
Compare plant and animal cellular structures: nucleus, mitochondria, cell wall, cell membrane, chloroplasts, and vacuoles.
An adult provides two safe leaves or other familiar natural objects. Look closely; do not taste them.
An adult reads each playground action. Say push or pull, then predict the motion.
Observe the weather at the same place and time for five days. Draw or write what you observe. Do not invent missing observations.
With adult guidance, hum gently and touch the front of your throat. Then stop humming. Record what you notice.
Read the animal behavior captions. Explain how each behavior helps young animals.
Use the material observations to choose a material for a job. Explain with evidence.
Follow the arrows in the two models. Explain how an animal helps a plant.
Use the evidence cards. Decide whether each example mainly shows inherited information, an environmental influence, or both.
Use the fictional trial results to make predictions. Keep the setup the same except for the tested variable.
Read the fictional observations. Explain energy transfer using evidence.
Compare waves drawn at the same horizontal scale. Amplitude is the height from the middle line to a crest. Wavelength is crest-to-crest distance.
Analyze the fictional measurements. Each closed container includes all its contents; nothing escapes.
Use the fictional observations from one Northern Hemisphere location. Identify patterns without treating one observation as a universal rule.
Use the particle models to explain states of matter. Particles themselves do not grow when matter expands.
Compare the simplified evidence maps. These teaching models illustrate evidence patterns, not exact geographic reconstructions.
Track matter and energy in these conceptual models. Plants also perform cellular respiration.
Use the fictional food web and counts. Arrows point from food to consumer. Evaluate explanations without claiming certainty.
Count atoms in the particle model. Rearrangement changes bonds, not the total number of each atom in a closed system.
Analyze the fictional beetle population. Color variation already exists, is inherited, and affects visibility to birds on dark bark.
