Day 1 | Air, Heat & Pressure | Grade 5 & 6

Air (Oxygen) is required for combustion

Experiment 1: Candle in glass

Experiment 2: Oxygen for combustion

Day 2 | Air, Heat & Pressure | Grade 5 & 6

Air expands when heated

Experiment 1: Air Expansion, Bottle and Balloon

Experiment 2: Air Expansion, Bottle and Coin

Day 3 | Air, Heat & Pressure | Grade 5 & 6

Air Expansion: Model of thermometer

Air Expansion: Model of thermometer

  • Children must do this experiment under the supervision of a responsible adult.
  • You can use a pair of tongs/forceps from the kitchen in place of the test tube holder.
Day 4 | Air, Heat & Pressure | Grade 7 & 8

Heat transfer in solids

In the last 2 days, we saw how air expands when heated. Over the next 4 days, we will see how heat travels in solids, liquids and gases.

Conduction in metals

  • Adult supervision required for this experiment.
  • Use a knife having a handle in place of the hacksaw blade.
Day 5 | Air, Heat & Pressure | Grade 7, 8 & 9

Heat transfer in liquids

Yesterday, we learnt how heat is transferred in solids. Today, we will do 2 simple experiments to see how heat is transferred in liquids.

Experiment 1: Convection in water

Experiment 2: Diffusion in water

Day 6 | Air, Heat & Pressure | Grade 7 & 8

Heat transfer in gases

Today, we are building a model to see how heat gets transferred in gases.

Convection in Air

Day 7 | Air, Heat & Pressure | Grade 7 & 8

States of water & relationship between Volume & Density

Experiment 1: Water Cycle

Experiment 2: Heating water in a paper cup

Experiment 3: Volume & Density

Experiment 4: Boyle’s Law

Day 8 | Light | Grade 7 & 8

Light’s path when traveling directly and after reflecting off a surface

Experiment 1: Light travels in a straight line

Experiment 2: Laws of reflection

Experiment 3: Tyndall Effect

Day 9 | Light | Grade 6, 7, 8 & 9

Refraction of light

Experiment 1: Refraction in water

Experiment 2: Total internal reflection

Experiment 3: Refraction in a glass slab

Use a glass filled with water, in place of a glass slab

Day 10 | Sound | Grade 5 and above

Sound, Loudness, Pitch

Experiment 1: Sound, a form of energy

Experiment 2: Sound, Loudness and Pitch

Day 11 | Energy, Force & Motion | Grade 7 & 8

Force acting on an object due to earth’s gravity (weight)

Pressure exerted by liquids

Day 12 | Force & Motion | Grade 7 & 8

Newton’s Laws of Motion

Experiment 1: Inertia,Newton’s First Law of Motion

Experiment 2: Hovercraft, Newton’s Third Law of Motion

You can substitute the pulley used in hovercraft with a small bottle cap. Make a small hole in it using a hot nail- take help from your parents.

Day 13 | Energy, Force & Motion | Grade 7 & 8

Kinetic Energy and Potential Energy

Experiment 1: Kinetic Energy & Potential Energy

Note:
If you don’t have access to balls of various sizes, you can use cylindrical plastic jars to roll down the slope. Check with your parents, first :)

Experiment 2: Centrifugal Force & Centripetal Force

Note:
As we are all home-bound right now, check with your parents what is the best place in your house to do this experiment. There is a chance you might hit something with the spinning eraser or spill water inside the house. :)

Day 14 | Chemistry & Biology | Grade 7 & 8

Preparation of Co2 and Osmosis

Experiment #1: Preparation of Carbon dioxide using Vinegar and Baking Soda or Cooking Soda

Note:
In this experiment, you can use a single air-tight bottle instead of 2 bottles connected through straws.

Experiment #2: Osmosis

Note:
You can do this experiment using Potato or raisins (dry fruit). Leave the samples in the test liquids overnight to see clear results.
