Life Science

What Is Alive: Objectives 1. I can identify whether something is living or not. 2. I can explain the characteristics of living and nonliving things. 3. I can compare and contrast living and nonliving things.

What Is Alive: Vocabulary 1. reproduce- when something makes a new living thing like itself 2 .grow- to get bigger 3. develop- to change over time 4. response- an action brought on by a change

What Is Alive: Guided Notes All living things reproduce and make new living things like themselves. Living things grow (get bigger) and develop (change over time). Living things are affected by changes around them, and a response is an action brought on by a change.

An example is when you walk out of the house on a cold day, you shiver to respond to the change around you. Animals and people take in their food by eating it. Plants and some other living things make their own food. Living things also move.

People and animals move from one place to another. Plants move by bending towards the sun. To be a living thing, it must be able to move on its own and eat or make its own food. Things that have never been alive are called nonliving things.

Partner Discussion: Is It Alive? Object What It Can and Cannot Do Is It Alive? Animal Can move, grow, develop, eat food, respond to changes around it, and reproduce.   Cloud Can move if wind pushes it. Can get larger and change shape. Cannot eat, make its own food, or reproduce. Plant Can move, grow, develop, respond to changes around it, make its own food, and reproduce. Rock Can move downhill. Cannot grow, develop, eat, make its own food, or reproduce.

Inheriting Characteristics: Objectives 1. I can compare and contrast inherited, learned, and acquired traits. 2. I can identify what type of traits a living thing has. .

Inheriting Characteristics: Vocabulary 1. trait- a quality or characteristic of a living thing 2 .inherited trait- traits a living thing gets from its parents 3. behavior- ways of acting 4. learned trait- a behavior that humans or other animals learn from their parents or in some other way 5. acquired trait- any trait that a living thing gets during its life

Inheriting Characteristics: Guided Notes A trait is a quality or characteristic of a living thing. Although living things have many traits, they acquire these traits in different ways. You may have inherited traits that you got from your parents, and these are traits that you were born with.

The color of your eyes and the shape of your nose are examples of inherited traits. Examples of inherited traits in plants and animals are: -a horse’s hair color -spots on a ladybug -a dog’s sense of smell -shape of the leaves on a maple tree

Inherited traits that determine how living things look, like eye color, are physical. Other inherited traits are ways of acting called behaviors. Examples of inherited behaviors include: -a dog chasing squirrels -spiders spinning webs -humans crying -

Mini Experiment 1. Look at the picture to the right. 2. What is the person doing? 3. Can you roll your tongue? Try it!! 4. Let’s make a bar graph to show who has this inherited trait! If you cannot roll your tongue, you cannot learn how to roll it. Rolling your tongue is an inherited trait.

A learned trait is a behavior that humans or other animals learn from their parents or in some other way. Examples of learned traits include: -a mother bear teaching her cub to find berries -a mother deer teaching her fawn to stay away from humans -a dog or horse staying away from electrical fence after being shocked

Inherited traits do not change, but learned ones can change over time. Being born with two legs is an inherited trait, and that does not change. But, knowing how to use your legs to play soccer is a learned trait that can change as you practice more. An acquired trait is any trait that a living thing gets during its life. Learned traits are acquired traits.

Examples of acquired traits include: -having a scar or a chipped tooth -a tree that is bent because wind blows against it from one direction All living things pass on traits to their offspring, but acquired traits are not passed on. You know how to ride a bike, but you children will not be born already knowing how.

When Environments Change: Objectives 1. I can classify living things as thriving, threatened, endangered, or extinct. 2. I can match a fossil to the living thing that it was formed from. .

When Environments Change: Vocabulary 1. extinct- no longer found on Earth 2. endangered- living things that could become extinct soon 3. threatened- living things that could become endangered soon 4. thriving- animals or plants that are doing well 5. fossil- the preserved remains or trace of a living thing from long ago

When Environments Change: Guided Notes Animals called mammoths once lived in many cold parts of the world. Mammoths were related to today’s elephants. Weather became warmer and forests grew which crowded out grasses that mammoths ate. These changes to their environment caused them to die out. Now mammoths are extinct, or no longer on Earth.

When a kind of living things is extinct, it is gone forever. Dinosaurs are another group of extinct animals. Once, millions of dinosaurs lived on Earth, but their environment changed, and they became extinct. A fossil is the preserved remains or trace of a living thing from long ago. Scientists can study fossils to learn more about plants and animals that are extinct.

Living things that could become extinct soon are called endangered. The white rhinoceros and tigers are endangered. Living things that could become endangered soon are said to be threatened. Northern spotted owls, gray wolves, and polar bears are animals that are threatened. Animals or plants that are doing well are called thriving.

Elephant seals were once endangered, but their numbers grew and now they are thriving. Changes in environment can cause living things to become extinct, but so can humans. Hunting, cutting down trees, and using chemicals to kill bugs are a few examples of how this happens. Many rules and laws protect living things that are threatened or endangered.
