Let's solve the science worksheet for Grade 1 step by step and explain each answer.

Q.1. Choose the best answer
a. Broccoli is an example of _________ (vegetable/fruit)
✔ Answer: vegetable
➡️ *Explanation:* Broccoli is a plant part we eat, specifically the flower head, but it is classified as a
vegetable in culinary terms. Botanically, some parts of broccoli could be considered fruits, but for this level, "vegetable" is the correct choice.
---
b. When the plants do not get enough water the plant will ____________. (wilt / grow well)
✔ Answer: wilt
➡️ *Explanation:* Plants need water to stay upright and healthy. Without enough water, they lose turgor pressure and begin to droop or
wilt.
---
c. __________ means moving unnoticed. (Creep/loud)
✔ Answer: Creep
➡️ *Explanation:* "Creep" means to move slowly and quietly, often without being noticed. "Loud" is the opposite — it’s about sound, not stealth.
---
d. __________ is an example of emergency vehicle. (Ambulance/caravan)
✔ Answer: Ambulance
➡️ *Explanation:* An
ambulance is used to transport sick or injured people quickly to a hospital — that makes it an
emergency vehicle. A caravan is a type of recreational vehicle, not an emergency one.
---
e. The water wheel is moved by the _________. (wind/water)
✔ Answer: water
➡️ *Explanation:* A
water wheel is turned by the flow of water, usually from a river or stream. Wind moves windmills, not water wheels.

Q.2. Circle true or false
1. All plants have roots
✘ False
➡️ *Explanation:* Not all plants have roots. For example, mosses and ferns (in some cases) don’t have true roots. They absorb water directly through their leaves or stems.
---
2. When we eat broccoli we are eating the seed
✘ False
➡️ *Explanation:* We eat the
flower buds and stems of broccoli. The seeds are tiny and not typically eaten. So, we are not eating the seed.
---
3. We human talk to share our ideas
✔ True
➡️ *Explanation:* Humans use speech to communicate thoughts, feelings, and ideas. This is a basic function of language.
---
4. Ringing phone is an example of sound source
✔ True
➡️ *Explanation:* A ringing phone produces sound, so it is a
source of sound. Sound sources are objects that create sound waves.
---
5. When you pick a pencil you are using the push force.
✘ False
➡️ *Explanation:* Picking up a pencil involves a
pulling force, not pushing. You pull the pencil toward your hand. Pushing would mean moving it away.
