Scientific Processes

(Texas Essential Knowledge and Skills)

Internet Resources

(1) The student conducts classroom and field investigations following home and school safety procedures.

(A) demonstrate safe practices during classroom and field investigations

(B) learn how to use and conserve resources and materials

(A) ask questions about organisms, objects, and events

(B) plan and conduct simple descriptive investigations

(D) construct reasonable explanations and draw conclusions

(E) communicate explanations about investigations

(3) The student knows that information and critical thinking are used in making decisions.

(A) make decisions using information

(B) discuss and justify the merits of decisions

(4) The student uses age-appropriate tools and models to verify that organisms and objects and parts of organisms and objects can be observed, described, and measured.

(A) collect information using tools including hand lenses, clocks, computers, thermometers, and balances

(B) record and compare collected information

(C) measure organisms and objects and parts of organisms and objects, using non-standard units such as paper clips, hands, and pencils

Science Concepts

(5) The student knows that organisms, objects, and events have properties and patterns.

(A) sort objects and events based on properties and patterns

(B) identify, predict, and create patterns including those seen in charts, graphs, and numbers

(6) The student knows that systems have parts and are composed of organisms and objects.

(A) sort organisms and objects according to their parts and characteristics

(B) observe and describe the parts of plants and animals

(C) manipulate objects such as toys, vehicles, or construction sets so that the parts are separated from the whole which may result in the part or the whole not working

(D) identify parts that, when put together, can do things they cannot do by themselves, such as a working camera with film, a car moving with a motor, and an airplane flying with fuel

(7) The student knows that many types of change occur.

(A) observe, measure, and record changes in size, mass, color, position, quantity, sound, and movement

(B) identify and test ways that heat may cause change such as when ice melts

(D) observe and record changes in the life cycle of organisms

(8) The student distinguishes between living organisms and nonliving objects.

(A) group living organisms and nonliving objects

(B) compare living organisms and nonliving objects

(9) The student knows that living organisms have basic needs.

(B) compare and give examples of the ways living organisms depend on each other for their basic needs

(10) The student knows that the natural world includes rocks, soil, and water.

(A) identify and describe a variety of natural sources of water including streams, lakes, and oceans

(B) observe and describe differences in rocks and soil samples

Science Concepts
(5) The student knows that organisms, objects, and events have properties and patterns.
(A) sort objects and events based on properties and patterns	Grouping and Changing Materials - look at objects, decide what they are made of and drag them into the correct box Variation - put a variety of plants and animals in the right groups
(B) identify, predict, and create patterns including those seen in charts, graphs, and numbers	Bar Chart - students create a bar chart showing quantities or percentages by labeling columns and clicking on values Pie Chart – Explore percentages and fractions using pie charts
(6) The student knows that systems have parts and are composed of organisms and objects.
(A) sort organisms and objects according to their parts and characteristics	Animal Behaviour Flashcards - thirty-three animal cards in the eleven categories Critter Craze - [this link opens on a new page] This lesson introduces the concepts of basic needs, grouping, and habitats. (Author - Laurie Ayers)
(B) observe and describe the parts of plants and animals	Animal Body Parts Flashcards - forty-five animal body parts cards in fifteen categories Animal Body Parts Flashcards - (a second source of cards to print) Animal Body Parts Lesson Plan - card games and worksheet activities, includes sheets to print
(C) manipulate objects such as toys, vehicles, or construction sets so that the parts are separated from the whole which may result in the part or the whole not working
(D) identify parts that, when put together, can do things they cannot do by themselves, such as a working camera with film, a car moving with a motor, and an airplane flying with fuel
(7) The student knows that many types of change occur.
(A) observe, measure, and record changes in size, mass, color, position, quantity, sound, and movement	Measurement Centimeters - To Nearest Whole Number (from FunBrain) Centimeters - To Half Centimeter (from FunBrain) Heaviest to Lightest - Look at the figures on each line. Click once on the lightest object. Click twice on the heaviest object. Inches - To Nearest Whole Number (from FunBrain) Inches - To Quarter Inch (from FunBrain) Sound Sound & Noise: Household Science for Kids - 2 different projects to help demonstrate some of the physics of sound Sounds and Hearing - experiment with sounds with this BBC quiz Changing Sounds - investigate how sounds can be changed
(B) identify and test ways that heat may cause change such as when ice melts	Earth in Space workshop - This 27 page lesson focuses on the fact that the sun's energy heats the Earth, and that rotation causes night and day.
(C) observe and record changes in weather from day to day and over seasons	Control the Weather - By clicking on different buttons, you decide what the weather will be that day. Eye on the Sky - the scientist (your student) is asked to enter weather observations. Based on the entries, a summary of conditions is compiled Make Your Own Weather Station - You can become an amateur meteorologist by building your own weather station and keeping a record of your measurements. Use this as a class project. Seasonal Changes Lesson Plans From Scholastic - The activities in this theme unit take advantage of opportunities for students to practice observation and description skills, as well as extending students' experience into other curricular areas, such as language arts and art. Seasons - [this link opens on a new page] this story will read itself to you. After students are familiar with the story, you can use a version that asks your students to do the reading. Weather in the Science Lab - Select Weather in the list of labs. The illustration shows a water cycle. Click on The Weather Maker near the top of the weather window. Set temperature of two air masses and the relative humidity. Then see what weather develops. Click on the book in the bottom left corner to read about weather.
(D) observe and record changes in the life cycle of organisms
(8) The student distinguishes between living organisms and nonliving objects.
(A) group living organisms and nonliving objects	Plants and Animals in the Local Environment - collect all of the living things in the environment pictured
(B) compare living organisms and nonliving objects
(9) The student knows that living organisms have basic needs.
(A) identify characteristics of living organisms that allow their basic needs to be met	Growing Plants - give water to the plants in this interactive game from the BBC Identify Basic Needs of Living Things - You may want to remove some slides from this show before using it.
(B) compare and give examples of the ways living organisms depend on each other for their basic needs
(10) The student knows that the natural world includes rocks, soil, and water.
(A) identify and describe a variety of natural sources of water including streams, lakes, and oceans
(B) observe and describe differences in rocks and soil samples
(C) identify how rocks, soil, and water are used and how they can be recycled	How Minerals are Used - Move your cursor over each image to see a common item made from that mineral.
