Teaching science to young students can be an exciting time. Kids are always amazed by the seemingly extravagant magic that happens. Try these simple and budget-friendly ideas to add a dash of science fun to your K-2 classroom. Science in the classroom doesn’t have to be a struggle or break the bank.

Science in the classroom- the fun way

I know what you’re thinking; experiments take up too much time. Don’t worry. These experiments are designed to take no more than 30 minutes, making them perfect for science centers or quick activities during your science block. Plus, we’ll sprinkle in some science standards that K-2 students typically learn throughout the year to ensure that your lessons align with educational goals.

Science Standards for K-2 Students

Before diving into the experiments, let’s touch on some of the science standards K-2 students usually cover in their curriculum. These standards vary depending on your location, but they often include topics like:

  • K-ESS2-2: Construct an argument supported by evidence for how forces responsible for plate motion cause changes to the Earth’s surface.
  • K-PS3-1: Make observations to determine the effect of sunlight on Earth’s surface.
  • 2-PS1-1: Plan and investigate to describe and classify different kinds of materials by their observable properties.
  • K-LS1-1: Use observations to describe patterns of what plants and animals (including humans) need to survive.
  • 2-LS4-1: Make observations of plants and animals to compare the diversity of life in different habitats.

These are just some of the standards covered in early elementary!

Implementing Science in the Classroom

Let’s get to the fun part—10 exciting experiments that will captivate your K-2 students while aligning with these science standards. These experiments are straightforward and highly affordable, and kids love them. Use them with any grade level to excite kids and keep them engaged.

1. Dancing Raisins (K-ESS2-2):

Materials: Clear soda (carbonated), raisins, and a clear glass.

Pour some soda into the glass and drop a few raisins in. Watch as they sink to the bottom and then rise to the top as if they are dancing. Discuss the concept of density and the gas bubbles in the soda that lift the raisins.

2. Solar S’mores (K-PS3-1):

Materials: Graham crackers, chocolate pieces, marshmallows, aluminum foil, and sunlight.

Assemble s’mores using the ingredients and wrap them in aluminum foil. Place the packets in direct sunlight, where the sun’s heat will melt the chocolate and marshmallows, creating delicious s’mores.

3. Magic Milk (2-PS1-1):

Materials: Milk, food coloring, soap, and a shallow dish.

Pour a thin layer of milk into the dish and add drops of food coloring. Dip a cotton swab in dish soap and touch the milk’s surface. Watch as the colors swirl and mix due to the surface tension and chemical reactions.

4. Plant Life Cycle (K-LS1-1):

Materials: Seeds (beans work well), small pots, soil, water, and sunlight.

Plant seeds in pots, water them and place them in sunlight. Observe and document the growth stages, discussing the plant’s life cycle from seed to maturity.

5. Balloon-Powered Cars (K-ESS2-2):

Materials: Balloons, straws, wheels (make little vehicles or use toy cars or other wheeled items), and tape.

Create small balloon-powered cars by attaching a balloon to a straw, securing wheels underneath, and releasing the air from the balloon to explore forces and motion.

6. Rock Candy Crystals (2-PS1-1):

Materials: String, a jar, water, sugar, and food coloring (optional).

Create a supersaturated sugar solution by dissolving sugar in hot water. Suspend a string in the jar and watch sugar crystals form on the string over time, explaining crystallization.

7. Terrariums (K-LS1-1):

Materials: Clear glass jars or containers, soil, small plants, and water.

Assemble a mini ecosystem in a jar with soil, small plants, and water. Discuss how plants and animals coexist and what they need to survive. This is a super simple activity to have going on all year long.

8. Baking Soda and Vinegar Volcano (2-PS1-1):

Materials: Baking soda, vinegar, a bottle, and craft supplies for decorating.

Create a volcano shape around a bottle, fill it with baking soda, and add vinegar to create a fizzy eruption, teaching about chemical reactions.

9. Weather Watchers (K-ESS2-2):

Materials: Thermometer, wind vane, and weather chart.

Set up a weather station with basic instruments and have students record daily temperature, wind direction, and weather conditions, understanding how to observe and document weather.

10. Sink or Float (2-PS1-1):

Materials: Various objects, water containers, and charts for predictions and observations.

Let students test different objects by placing them in water to discover which ones sink and which float, exploring concepts of density and material properties.

See, science in the classroom doesn’t have to be complex. It can be straightforward and tons of fun!
