Trained to be a Scientist:
Dear children, Do you know how scientists work? From where do they start? How have they made
different discoveries and inventions? How do they conduct experiments and reach conclusions?
Let us read the steps information below to understand the various steps of
scientific method.
In science there are ways and methods to find answers to any question. Scientific
methods are ways of finding answers.
Scientists use scientific methods when they do experiments which might have
many steps. Sometimes scientists do steps in a different order. They might or
might not even do all the steps every time. We all have those scientists hidden in
us. 
 Step 1: Frame your question
Think and frame a question that you want to be answered.
 Ex: Do seeds need water to grow?
Do seeds need anything else than water?
 Step 2: Make your Hypothesis.
A hypothesis is a possible answer to your question.
 Ex: If seeds are watered, then they will grow because seeds need water.
 Step 3: Plan a Test
Keep everything the same. Try and change one thing and observe.
 Ex: Use the same kinds of pots, Seeds, soil etc but water only one pot.
 Step 4: Perform the test
Test what you thought of while making the hypothesis. Repeat your test. Compare the
results.
 Step 5: Collect and record what you observed
Keep the records of whatever you have observed. You can record with numbers,
drawings, writing sentences. Etc.
 Step 6: Tell your conclusion
Once you finish, think of the question and the hypothesis you framed
 Ex: Do seeds need water to grow?
Yes, they need water to grow
1. That was quite an informative reading! Let us follow these steps and become investigative
young scientists to find out about the following in plants:

Is water required for growing plants?
Is sunlight necessary for growing plants
A. Activity 1
1. Buy some healthy seed from a gardening store or a nursery. You can even take some from
your kitchen.
2. Take two small-flat pots. Put a layer of healthy soil (soil with manure) in the pot and place the
seed in both. Cover it with another layer of soil.
3. Label the first pot as “With water” and the other pot as “Without water”.
4. Water the first pot (the one that says- “With water”). Do not water the other one.
5. Observe the pot daily for 5 days.
6. Record your observations on a daily basis in the table given below. Draw the table in your
Spiral Notebook.

B. Activity 2
Let us try the second activity now.
1. Again take 2 pots and label the first one as “in the sunlight” and the second one as “ in the
shade”.
2. Water both the pots, but keep one of them in the sunlight and the other one in shade.
Record your observations on a dali basis and note the data in the table below.


Do you think the plant in the sunlight will grow faster than the one in shade? Predict your
answer and then see the results yourself after 5 days.
Prediction : __________________________________________________
Actual :


Observe both the plants after 5 days. What was the colour of :
a. the plant “In the sunlight”:
____________________________________________________________________________
b. the plant “In the shade”:
_____________________________________________________________________________

What will happen if we now keep the second potted plant kept “in the shade” out in the
sunlight after 5 days?
 Prediction: : __________________________________________________________
 Actual :
___________________________________________________________
Do you notice any change in :
a. Growth
b. Colour
 What do you infer from this?
___________________________________________________________________________
2. Visit a nearby Botanical Garden or a park. Carefully look around the variety of plants
present there. Observe and try to find out the following information for any 5 plants that are

3. With the help of an encyclopedia and websites like1. www.amazingfacts.com
2.www.makemegenious.com
3. www.sciencekids.co.nz/sciencefacts/animals.html.
Try and find out 10 amazing facts about plants and animals. Write these facts on strips of
chart papers so that we can share and display them on class boards once you come back to
school . Kids, find out really interesting facts. You never know we might read them out in
the morning assembly too.
4. Let’s do some Magic!!
1. Draw a flower on plain white paper and colour it in with coloured
pencils or crayons (felt pens will run). You can download and print
these flowers or design your own.
2.Carefully cut the flower out (the neater
the better)
3. Fold the petals over one by one (the
flower will open up differently depending
on the order you fold the petals
4. Your Magic Flower should now look like this.
(as shown in the picture)
5. Pour a teaspoon of water into a saucer.
6. Pop the Magic Flower into the water in your
saucer and the petals immediately begin to
open up... just like a real flower blossoming!
7. Soon, the petals untangle and reveal the
smiley face (or any other message you wrote) inside.
8. The flower will completely open in around thirty seconds (it varies
depending on the paper you used). This will surely get a smile on your
face.
Try it out and have fun! Also attempt the
questions given below.
1. Was your magic a success? If not try different papers.
2. At any point of time, did you find it difficult to perform this
activity? If yes, how did you overcome it?
3. Can you figure out the reason for the petals to open up?
5. Go to big bazaar or any other supermarket with your parents. Surely, you will see lot of tasty
food items lined up. Once you finish grocery shopping, have a look at what all you have bought.
Collect labels of healthy and unhealthy food items (5 each) and make the following table:
