Procedure 

  1. Mould the clay into a volcano shape around the small plastic bottle, leaving the top open.

  2. Add a spoonful of baking soda into the bottle.

  3. Mix a few drops of dish soap with vinegar in a separate container.

  4. Pour the vinegar mixture into the bottle and watch your mini volcano erupt!

Explanation 

This experiment introduces kids to the concept of chemical reactions. The baking soda and vinegar combine to produce carbon dioxide gas, causing the eruption.

Paper Plane Aerodynamics

Materials Required 

  • Sheets of paper

Procedure 

  1. Create various paper planes using different designs, wing sizes, and shapes.

  2. Take your planes outside and test how far they fly when thrown with the same force.

Explanation 

This experiment allows students to understand the basic principles of aerodynamics. They can observe how different plane designs affect factors such as lift, drag, and thrust.

Sink or Float  Discover Buoyancy with Household Items

Materials Required 

  • A tub of water

  • Various objects from around the house (e.g., toy cars, coins, rubber balls, wooden blocks, plastic toys)

Procedure 

  1. Ask your child to predict whether each item will sink or float.

  2. Submerge each item in the tub of water to test their predictions.

Explanation 

This experiment introduces students to the concept of buoyancy. It helps them understand that objects float or sink based on their density and the amount of water they displace.

Colour-Changing Milk 

Materials Required 

  • Milk

  • Food colouring

  • Dish soap

  • A shallow dish

  • Cotton swab

Procedure 

  1. Pour a small amount of milk into the shallow dish.

Grade 7 marks a vital point in a student's learning journey. It's when they encounter intricate scientific ideas. The experiments aim to deepen their grasp of core science principles – physics, chemistry, and biology – all while sparking strong interest and curiosity.

Balloon Rocket Experiment

 Materials Required

  • A long piece of string

  • A plastic straw

  • A balloon 

  • Tape

Procedure

  1. Secure one end of the string to an immobile object, like a doorknob or the rear of a chair.

  2. Thread the string through the straw, letting the straw glide smoothly on the string.

  3. Expand the balloon and grasp the opening to contain the air within.

  4. Fasten the balloon to the straw with tape.

  5. Free the balloon's opening, and the air's release will drive the balloon forward along the string.

Explanation

This test showcases Newton's third law  Every action has an equal and opposite reaction. In this scenario, the action is air escaping from the balloon, and the reaction is the balloon moving forward.

Make a Solar-Powered Oven

 Materials Required

  • A pizza box

  • Aluminium foil

  • Plastic wrap

  • Black construction paper

  • A thermometer

Procedure

  1. Open the pizza box and line the inside of the lid with shiny-side-out aluminium foil.

  2. Cut a flap in the lid, leaving a border to serve as a reflector; also cover this flap with aluminium foil.

  3. Put a black construction paper at the box's bottom.

  4. Close and seal the box with tape.

Explanation

This experiment acquaints students with the notion of utilising solar energy for real-world applications. The aluminium foil reflects sunlight into the box, where it is absorbed by the black paper, generating heat. This makeshift oven demonstrates the principles of solar heating and can be used to melt s'mores or chocolate.

Create a Rainbow in a Glass

 Materials Required

  • A glass

  • Water

  •  Flashlight

  • A piece of white paper

Procedure

  1. Pour water into the glass, leaving room at the top.

  3. Direct a flashlight through the glass, letting the light travel through the water.

  4. Place a white paper on the opposite side of the glass to witness a splendid rainbow.

Explanation

This experiment illustrates the concept of refraction, which is the bending of light as it passes from one medium (air) into another (water). Different colours of light bend by different amounts, creating the rainbow effect. It's a fascinating way to explore the physics of light.

Homemade Lava Lamp

 Materials Required

  • A clear plastic bottle

  • Vegetable oil

  • Water

  • Food colouring

  • Alka-Seltzer tablets

Procedure 

  1. Pour water into the plastic bottle, filling it to about one-third.

  2. Top off the bottle with vegetable oil, but leave some space at the top.

  3. Introduce a couple of drops of food colouring to the liquid.

  4. Break an Alka-Seltzer tablet into smaller bits and place them in the bottle.

  5. Observe as bubbles move up and down, producing a lava lamp-like display.

Explanation 

This experiment demonstrates density and how liquids with different densities interact. Oil and water don't mix due to their differing densities. Alka-Seltzer tablets produce gas bubbles that rise in the water and sink through the oil, illustrating the concept of buoyancy.

Create an Electromagnet 

 Materials Required  

  • A nail

  • Insulated copper wire

  • A battery

  • Electrical tape.

Procedure 

  1. Wrap the insulated copper wire tightly around the nail, leaving some wire free at both ends.

  3. The nail becomes a temporary magnet when the current flows through the wire. You can test its magnetic properties by picking up small metal objects, such as paper clips.

Explanation 

This test reveals the fundamental concepts of electromagnetism. When electricity runs through a wound wire, it generates a magnetic field encircling the wire, changing the nail into a magnet. Turning off the current demagnetizes the nail. It's a simple way to understand how electromagnets work and their various applications.
