Physics Experiments

Physics deals with matter, motion, electricity, light, and more. Physics experiments enable kids to explore core scientific concepts like energy, gravity, friction, magnetism, and force:

Gravity Ball Drop

Supplies Needed: Golf balls, meter stick or yardstick, smartphone stopwatch app

This experiment examines how gravity affects the speed of a falling object.

  1. Hold a ball at a set height, perhaps 1 meter above the ground.
  2. Use the stopwatch to time how long it takes to drop to the ground.
  3. Repeat several times and calculate the average time.
  4. Now drop the ball from higher points like 2 meters or 3 meters.
  5. Calculate the new average times.

What’s happening? Gravity accelerates the balls so they fall faster from higher up. Plot the data to visualize the relationship between drop height and time.

Balloon Rocket Car

Supplies Needed: Balloon, string, straw, tape, wheels (or materials to make wheels like CDs)

Harness the power of escaping air to propel a balloon rocket car across the room!

  1. Inflate a balloon and pinch the neck to temporarily trap the air inside.
  2. Tape a straw along the body of a balloon. This is the “rocket nozzle”.
  3. Attach wheels and assemble a chassis from cardboard, craft sticks, etc.
  4. Feed string through the straw and attach to a fixed point.
  5. Let the balloon neck go and observe the rocket car zoom away!

What’s happening? The escaping air provides a propulsive force that drives the car forward. Adjust the balloon size, nozzle size, and chassis design to optimize performance.

Chemistry Experiments

Chemistry deals with matter, chemical reactions, acids and bases, and forces between atoms:

Baking Soda and Vinegar Reactions

Supplies Needed: Baking soda, vinegar, transparent cups, food coloring (optional)

Observe a classic chemical reaction first-hand:

  1. Pour vinegar into a cup until it’s about 1 inch deep.
  2. Add a few drops of food coloring (optional).
  3. Pour baking soda into the vinegar and watch fizzing bubbles erupt!

What’s happening? An acid-base reaction occurs between the acetic acid in the vinegar and the sodium bicarbonate in the baking soda. Carbon dioxide gas is produced.

Magic Milk

Supplies Needed: Shallow plate, milk, liquid dish soap, cotton swabs, food coloring

Investigate the molecular forces that allow soap to interact with fats:

  1. Pour enough milk in a plate to make a thin layer on the bottom.
  2. Add several drops of different food colorings around the milk.
  3. Dip a cotton swab in dish soap and gently touch the center of the milk.
  4. Watch a colorful pattern form!

What’s happening? Milk contains fat molecules that normally repel each other. But soap molecules can disrupt and react with fat, causing the colorful dyes to spread.

Biology Experiments

Biology involves living organisms, plants, our bodies, ecosystems, microscopic life, and more:

Make an Indoor Ecosystem

Supplies Needed: Jar, pond water, pond plants and animals

Create a mini ecosystem in a jar to observe adaptations and interactions:

  1. Collect shallow pond water, plants like duckweed or elodea, and tiny animals like snails, fish, or shrimp.
  2. Gently place them in a clean jar and seal the lid. Ensure organisms have air and light.
  3. Observe the tiny ecosystem over days. Add fish food if needed.

What to look for: Animals finding food and shelter, gas bubbles released by plants, microorganisms in the water, small insect larvae, etc. It’s an up-close look at ecological connections!

Build a Lung Model

Supplies Needed: Plastic bottle, balloon, straws, rubber band

Learn how lungs work by constructing a model:

  1. Carefully cut off the bottom third of a plastic bottle.
  2. Stretch a balloon over the cut top to create an “airtight lung”.
  3. Attach straws into the side of the bottle to represent bronchi/airways.
  4. Draw on the balloon with Sharpie to represent the lungs and diaphragm.
  5. Seal the balloon to the bottle seam with a rubber band.
  6. Pull on the balloon to observe it inflating and deflating like a lung!

What’s happening? This models how the diaphragm and rib muscles change lung volume during breathing. Air flows through the bronchi into the balloon “lungs”.

Engineering Experiments

Engineering uses science to invent, design, and build things. Try these experiments to think like an engineer:

Make a Catapult

Supplies Needed: Popsicle sticks, rubber bands, plastic spoon, plastic cup

Engineer a mini catapult to launch objects across the room:

  1. Stack popsicle sticks to build a base and lever arm.
  2. Attach the lever arm with rubber bands to allow hinged movement.
  3. Affix a plastic spoon at the end of the lever to act as the catapult cup.
  4. Load an object like a cotton ball or crumpled paper.
  5. Pull down the lever arm to store energy and release it to launch!

Catapult physics: Adjust the arm length, rubber band tension, and launch angle to hit targets across the room.

Design a Bridge

Supplies Needed: Craft sticks, tape, textbooks or weights

Take on the challenge engineers face when building real bridges:

  1. Use craft sticks and tape to design a model bridge between two stacks of books around 6 inches apart.
  2. Test its strength and stability by placing books or other weights in the center until it collapses.
  3. Redesign to improve your bridge by changing the truss design or number of supports.

Engineering mindset: Analyze failure points, rethink and iterate design, build prototypes, and test again!

Electricity and Magnetism Experiments

Harness the invisible powers of electricity and magnetism:

Make a Battery from Fruits and Coins

Supplies Needed: Lemon, copper penny, galvanized screw/nail, LED light bulb

Harness citric acid to generate electricity:

  1. Insert a galvanized nail and copper penny into a lemon as the 2 electrodes.
  2. Connect each electrode to an LED light bulb with a wire.
  3. Observe it light up from the lemon battery’s flow of electrons!

How batteries work: Chemical reactions within the lemon cause an electric charge difference that makes electrons flow through the wires and light bulb.

Build a Magnetic Maze

Supplies Needed: Sheet of cardboard, magnets, paperclips

Construct a maze to guide a paperclip through using only magnets:

  1. Arrange strong magnets below a cardboard sheet in guidance pathways.
  2. Drop a paperclip onto the cardboard and tilt it to move the clip through the “maze”.
