Baking Soda & Vinegar Volcano (Chemistry)

  • What you need: Baking soda, vinegar, food coloring (optional), a plastic bottle, a tray.

  • What to do: Place baking soda into the bottle and pour vinegar over it to create a fizzy “volcano” eruption. The reaction is caused by the acid-base interaction.

  • Learning Outcome: Kids learn about chemical reactions, acids and bases.

  • What you need: Honey, corn syrup, dish soap, water, vegetable oil, rubbing alcohol, food coloring, and a tall clear jar.

  • What to do: Layer the different liquids in the jar from heaviest to lightest, adding food coloring to each layer. You will create a colorful rainbow effect.

  • Learning Outcome: Teaches about liquid density and how substances with different densities stack without mixing.

  • What you need: A pizza box, aluminum foil, plastic wrap, black construction paper, tape, and a thermometer.

  • What to do: Line the pizza box with aluminum foil, place black paper at the bottom, and cover it with plastic wrap. Use the sun’s rays to heat and cook food, like s’mores!

  • Learning Outcome: Teaches how solar energy can be harnessed for cooking, and basic principles of heat transfer.

  • What you need: Small plants, cups, soil, water, a sunny spot, and a dark spot.

  • What to do: Place plants in different conditions – some in the sun, some in the dark, some with water, etc., and track their growth.

  • Learning Outcome: Understands photosynthesis, plant biology, and the importance of environmental factors.

  • What you need: Cornstarch, iron filings, liquid starch, a bowl, and a magnet.

  • What to do: Mix cornstarch with liquid starch, then add iron filings. Use a magnet to move the slime around.

  • Learning Outcome: Teaches about magnetism and how magnetic fields interact with materials.

Simple Water Filtration (Environmental Science)

Concept: Water Filtration and Environmental Science

  • Materials Needed:

    • A plastic bottle (cut in half)

    • Sand

    • Gravel

    • Activated charcoal (optional)

    • Coffee filter or cloth

    • Dirty water (can add dirt to water for more fun)

How to Do It:

  1. Cut the plastic bottle in half and use the top part as a funnel.

  2. Place a coffee filter or cloth at the bottom of the bottle to filter out larger particles.

  3. Layer sand, charcoal, and gravel in the bottle.

  4. Pour dirty water into the bottle and watch as the water is filtered and clean water flows out.

Learning Outcome:

  • Students learn about water filtration, environmental pollution, and the importance of clean water in the world.

Concept: Timekeeping, Earth’s Rotation

  • Materials Needed:

    • A paper plate

    • A pencil or straw

    • Markers

    • Stopwatch or clock for reference

How to Do It:

  1. Place the paper plate flat on the ground on a sunny day.

  2. Stick the pencil or straw through the center of the plate so that it stands upright.

  3. Over the course of several hours, mark where the shadow falls on the paper plate at different times.

  4. Compare the marks to the time on your clock to create your own sun dial.

Learning Outcome:

  • Teaches kids about the Earth’s rotation, the concept of time, and how people used the sun to tell time before clocks were invented.

Concept: Density and Buoyancy

  • Materials Needed:

    • A bowl or container of water

    • Various small objects (e.g., an apple, a rock, a plastic spoon, a metal spoon, a rubber ball)

How to Do It:

  1. Fill a bowl with water.

  2. Take each object and drop it into the water.

  3. Observe whether the object sinks or floats. Discuss why some objects float while others sink.

Learning Outcome:

  • Students learn about density, buoyancy, and the difference between objects that float and those that sink.
