Sink and float experiment one at a time- Nature Trip
Learn the concept of sink and floatUnderstand which objects will sink or which will float
Children are introduced to the concept of sinking and floating in water, so that they realize and build their observation skills on materials that will float or sink. To build in a scientific temper of the child
Collection of things found in nature-
Rocks, dry leaves, green leaves, flower and twigs
Small plastic tubs
Water
Paper towels

Step 1: You can begin the class by asking children simple questions like when they take a bath in the tub or when they put anything in water then what happens.

Objective is to make them connect with the situation which they have experienced multiple times but now you are trying to draw their attention to this concept of sinking and floating

Step 2: If you have the opportunity to take kids out in the school lawn or outdoors then take them on a nature walk and ask them to collect the following items:

  1. Pieces of stick or twigs
  2. Flowers
  3. dry or green leaves
  4.  Small Stones

(Else you can collect all these items and get it for the class.)

Step3: Once you have collected all these items divide the children in groups and ask them to put one thing at a time in their tubs filled with water.

Like They first put in twigs and see what happened.

Ask children what is happening to the twig in the water. Did it go down and touch the tub or is it moving on the water

Next flower- Ask children what is happening to the flower in the water. Did it go down and touch the tub or is it moving on the water

Next Dry leaves- Ask children what is happening to the dry leaves in the water. Did it go down and touch the tub or is it moving on the water

Explain them that this concept is known as floating. With these examples we have made them understand what is floating.

Step4: Now take the last item they collected. ie stones. Ask children what is happening to the stone in the water. Did it go down and touch the tub or is it moving on the water.

Let them answer the question. try to get the answer from each group.

Once they have answered then tell them that stone has sunk in water.

Now give them a work sheet of their to tick whether it floats of sinks.

what do they think will happen to twig flower or dry leave when put in water before putting it in water.
Accurate, Knowledgeable, Coordinated, Polished

In the first class, when introducing the concept of Float and sink its best if you show the students either all the things that you have collected that will float first and then show them objects that will sink. do not alternate the sequence. Children tend to get confused with the concept of floating and sinking. In future classes give them other worksheets where they can guess what will float or sink. if possible then repeat this experiment with other items
