Collecting and Examining Life

Science Content

Cluster 1: Living Things

  • There are many criteria that distinguish living things from non-living things.
  • Living things have needs. They can only survive in environments where their needs can be met.
  • Many different kinds of living things can share an environment.
  • Living things can be classified into different groups.
  • Animals, plants, and fungi are living things.

Cluster 2: Animals

  • Animals move, breathe, eat, and sense their environment.
  • Animals have body parts to help them move, breathe eat, and sense their environment.
  • Different animals have different body parts related to these functions.

Cluster 3:  Plants

  • Plants have many parts that work together to help them grow and make new plants.
  • Leaves use sunlight to make food for the plant.
  • Fruits contain the seeds of a plant.
  • Seeds grow into new plants. They disperse from their parent plant in various ways.
  • Roots transport water and minerals from the soil to the upper plant.
  • Stems support a plant and move nutrients and water up and down the plant.
  • Flowers develop into fruits.

Cluster 4:  Fungi

  • Fungi live directly on their food source.
  • Fungi grow best in warm, moist environments. They do not need light.
  • Fungi play an important part in nature as decomposers.

 

Motion

Science Content

Cluster 1: Describing Motion

  • Motion is movement.
  • Motion always follows a path.
  • Motion has speed, which is related to how far something goes (distance) and how long it takes (time).
  • You can describe an object’s motion by how long it takes, how far the object travels, how fast the object moves, and what path it follows.

Cluster 2: Changing Motion

  • The way to change how something moves is to give it a push or a pull.
  • Starting, speeding up, slowing down, and changing direction all represent changes in motion.
  • There are many sources of pushes and pulls.
  • There are different sizes of pushes and pulls. Bigger pushes and pulls (forces) cause bigger changes in motion than smaller forces do.
  • Collisions cause pushes that may change the motion of all the colliding objects.

Cluster 3:  Friction and Gravity

  • Friction is a force (a pull) that slows down moving objects.
  • If there is a lot of friction between surfaces, a moving object slows down quickly. If there is not much friction between surfaces, a moving object slows down more gradually.
  • OnEarth, gravity is a force that pulls everything down all the time.

 

Weather

Science Content

Cluster 1: Weather Conditions

  • The main parts of weather are temperature, sunlight, wind, clouds, and moisture.
  • Meteorologists—people who study weather—use symbols and descriptive terms to communicate about weather.
  • Weather is measurable.
  • Thermometers measure temperature.
  • Sunlight both illuminates and warms.

Cluster 2:  Weather Patterns

  • A weather pattern is weather that repeats or follows an order.
  • Simple graphs can help scientists communicate their observations.
  • Data is a fact about something observed.

Cluster 3:  Water

  • Understanding how water changes—from liquid to a vapor or a solid—is essential to understanding weather.
  • Three basic cloud shapes are cumulus, cirrus, and stratus.
  • Water can be a part of the air, an invisible gas called water vapor.
  • Water can condense out of the air onto cold surfaces, a phenomenon called dew.
  • Frost is water that comes out of the air and forms as ice crystals.
  • Snowflakes form in six-sided or six pointed patterns.

Cluster 4:  Air and Wind

  • Air is all around us.
  • Wind is moving air.
  • Scientists and meteorologists use various tools to measure wind’s strength, speed, and direction.
