My kids love to get their hands dirty when they learn, sometimes quite literally. This makes our home that much messier and livelier. With two kids in separate grades, discussions over what to work on can turn into a rough tumble of ideas.
Over the years, I have compiled a list of science fair project ideas that I have used and sorted them out grade-wise (kindergarten to third grade so far) so that we have an easier time finding the right project (or subject) based on my kids’ curriculum, interest and relevance.
Kindergarten – Projects can be nature-based. Science fair project ideas that kids can explore include the weather, plants and animals. Kids can grow plants to understand what a plant needs to grow. This could be in the form of growing a bean plant in cotton wool or grouping plants and studying their growth when they are exposed to sunlight and water, and when they are not. Other simple experiments include understanding the density of fluids (oil and water) and demonstrating displacement by dropping pebbles into a jar of water. Collecting different types of leaves and flowers to understand their structure, and sorting seeds from fruits and vegetables is something kids enjoy.
First Grade – Kids can move beyond curiosity and start learning to make and record observations. They can perform experiments with water to understand the states of matter (solid, gas and liquid). Other experiments can revolve around the five senses. Kids can interact with objects using only one of their senses and jot down observations. Other concepts that kids can learn include rain and cloud formations, the solar system, colors and surface tension.
Second Grade – When your kids get to the second grade, they can start experimenting with electricity and magnetism, animals and lifecycles, study anatomy, and learn more about the earth. Making a bird feeder to track bird species in the neighborhood is a popular project. Apart from continuing to collect data and making observations, kids can also start making models and presentations. Drawing the life cycles of insects and their anatomy, the most popular being a butterfly, is a good way to start. Observing mold to understand the effects of heat, humidity and other factors that cause mold is another easy to put together projects that second graders can work on.
Third Grade – By the time kids get to third grade, they should be able to observe, collect, conduct experiments, record observations and form hypothesis. Science fair project ideas that you can consider are motion and sound, electricity and magnetism, animal and plant life, the human body, and the earth and solar system. Children can study chemical reactions like rusting and making soaps. Third graders can try their hand at making sundials, volcanoes, model airplanes and even a simple electric circuit.
These are just a few of the science fair project ideas I have tried with my kids. It helps to talk to their science teacher, figure out the subjects that they will be studying, the extent to which they can explore a subject and grasp a concept, and their own interest before zeroing in on an idea.
