P: Physical Sciences

P.1: Energy and matter have multiple forms and can be changed from one form to another. As a basis for understanding this concept:

P.1.a: Students know energy comes from the Sun to Earth in the form of light.

Energy Conversions

P.1.d: Students know energy can be carried from one place to another by waves, such as water waves and sound waves, by electric current, and by moving objects.

P.1.e: Students know matter has three forms: solid, liquid, and gas.

Phases of Water

P.1.f: Students know evaporation and melting are changes that occur when the objects are heated.

P.1.h: Students know all matter is made of small particles called atoms, too small to see with the naked eye.

L: Life Sciences

L.3: Adaptations in physical structure or behavior may improve an organism's chance for survival. As a basis for understanding this concept:

L.3.a: Students know plants and animals have structures that serve different functions in growth, survival, and reproduction.

Flower Pollination
Flower Pollination

L.3.c: Students know living things cause changes in the environment in which they live: some of these changes are detrimental to the organism or other organisms, and some are beneficial.

E: Earth Sciences

E.4: Objects in the sky move in regular and predictable patterns. As a basis for under-standing this concept:

E.4.b: Students know the way in which the Moon's appearance changes during the four-week lunar cycle.

Phases of the Moon

E.4.d: Students know that Earth is one of several planets that orbit the Sun and that the Moon orbits Earth.

E.4.e: Students know the position of the Sun in the sky changes during the course of the day and from season to season.

Seasons: Earth, Moon, and Sun
Seasons: Earth, Moon, and Sun

I: Investigation and Experimentation

I.5: Scientific progress is made by asking meaningful questions and conducting careful investigations. As a basis for understanding this concept and addressing the content in the other three strands, students should develop their own questions and perform investigations. Students will:

I.5.a: Repeat observations to improve accuracy and know that the results of similar scientific investigations seldom turn out exactly the same because of differences in the things being investigated, methods being used, or uncertainty in the observation.

Real-Time Histogram

I.5.b: Differentiate evidence from opinion and know that scientists do not rely on claims or conclusions unless they are backed by observations that can be confirmed.

Diffusion

I.5.d: Predict the outcome of a simple investigation and compare the result with the prediction.

Pendulum Clock

I.5.e: Collect data in an investigation and analyze those data to develop a logical conclusion.
