Grade 4. Science Worksheet. Interactive worksheet | TopWorksheets - Free Printable

Let's solve the science worksheet step by step. The task is to match each term with its correct definition.

---

Part A: Match each term with its definition

We are given two sets of terms:

First set:
- life cycle
- metamorphosis
- embryo
- larva
- pupa
- nymph

Second set:
- climate
- elevation
- latitude
- habitat
- atmosphere

Now, let’s go through each definition and match it to the correct term.

---

#### 1. _______ the process of an animal changing form during its life cycle

✔ Answer: metamorphosis
*Explanation:* Metamorphosis is the biological process by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in form.

---

#### 2. _______ the stage of a human life cycle before the infant stage

✔ Answer: embryo
*Explanation:* In humans, the stage before birth (before the infant stage) begins as a zygote and then becomes an embryo (from fertilization to about 8 weeks), then a fetus. So, "embryo" is the correct term for the early developmental stage before infancy.

---

#### 3. _______ a pattern of birth, growth, and death that all animals share

✔ Answer: life cycle
*Explanation:* The life cycle refers to the series of changes an organism goes through from birth to reproduction to death.

---

#### 4. _______ the caterpillar or worm-like stage in the life cycle of some insects

✔ Answer: larva
*Explanation:* A larva is the immature, often worm-like stage of an insect (e.g., caterpillar of a butterfly).

---

#### 5. _______ an insect in the stage of its life cycle in which it changes from a larva to an adult

✔ Answer: pupa
*Explanation:* During pupation, the insect undergoes transformation inside a pupa (e.g., chrysalis in butterflies). This is the stage between larva and adult.

---

#### 6. _______ a young insect which looks like a small adult

✔ Answer: nymph
*Explanation:* A nymph is a juvenile stage in insects that undergo incomplete metamorphosis (like grasshoppers). It resembles the adult but is smaller and lacks wings.

---

Now, second set of terms:

#### 7. _______ the height above sea level

✔ Answer: elevation
*Explanation:* Elevation is the vertical distance above sea level.

---

#### 8. _______ the layer of air around Earth

✔ Answer: atmosphere
*Explanation:* The atmosphere is the layer of gases surrounding Earth.

---

#### 9. _______ the weather conditions over a long time

✔ Answer: climate
*Explanation:* Climate refers to average weather patterns over a long period (typically 30 years or more).

---

#### 10. _______ a measure of how far a place is from the equator

✔ Answer: latitude
*Explanation:* Latitude measures how far north or south a location is from the equator, in degrees.

---

#### 11. _______ a place where a living thing lives

✔ Answer: habitat
*Explanation:* A habitat is the natural environment where an organism lives and finds food, shelter, and space.

---

✔ Final Answers:

1. metamorphosis
2. embryo
3. life cycle
4. larva
5. pupa
6. nymph
7. elevation
8. atmosphere
9. climate
10. latitude
11. habitat
