Stuck home and looking for something to keep the kids busy? Science experiments are a fun and educational way to bust the boredom and keep learning. However, what if you don’t have a huge chemistry set or expensive scientific tools? You can do amazing experiments with items you find around your house that employ the scientific method. Here are 5 simple science experiments for kids.
What Science Experiments Can You Do with Household Item?
Project: Apple Rotting Liquid
Question: Which liquid makes apples rot the quickest?
Materials: Apple cut into thick slices, clean jars, various liquids (for example: vinegar, olive oil, water, corn syrup, salt water), pencil, and paper
- Gather materials.
- Have each child hypothesis which liquid will rot
- Fill jars with liquids being used. Label each jar.
- Create a chart or journal to record observations.
- Place an apple slice in each jar.
- Record daily observations for each liquid.
- After 5-7 days remove apple slices and record final results. See how they compare to original hypothesis.
How Do Boats Float?
Project: Tinfoil Boat Floating Experiment
Question: What tinfoil boat design will hold the most pennies and still float?
Materials: tinfoil, pennies, basin or sink that holds water, pencil, and paper
- Gather materials.
- Draw our various designs and hypothesize which will hold the most pennies and float.
- Make boats out of tinfoil.
- Fill basin or sink with water.
- Float boats one at a time in the water.
- Gradually add pennies and keep a tally of how many you add.
- When one boat sinks, float the next and repeat the process.
- As an extension activity make modifications to your original designs and test to see how it changes your outcome.
Simple Science Experiments for Kids with Water
Project: Sink or Float
Question: Which household items will sink and which will float?
Materials: Basin or sink full water, collection of household items, paper and pencil
- Decide which items you want to test, gather materials. Make sure all items can get wet safely.
- Fill a basin or sink with water.
- Hypothesize which items will float or sink. Record your hypothesis.
- Place items into the water, gently, one at a time.
- Record which ones float and which ones sink.
- Check results against the original hypothesis.
- As an extension activity, retest the items in saltwater.
What Germs Are Lurking in Your House?
Project: Germs in bread
Question: Which surfaces have the most germs?
Materials: loaf of sliced bread, zipper closure plastic bags, items around house, permanent marker, pencil, and paper
- Decide which surfaces you want to test.
- Label plastic bags with surfaces you choose.
- Thoroughly wash and dry your hands.
- Rub one slice of bread on each surface and place in corresponding baggie.
- Places baggies flat in a safe place where they will not be disturbed.
- Create a chart for daily observations.
- After a week, compare results to hypothesis.
- As an extension activity, rub dirty hands on a slice or bread. Then repeat with newly washed hands.
What Simple Science Experiments Use Eggs?
Project: Egg Observations
Question: How do various liquids effect eggs? Which ones will dissolve the shell?
Materials: Eggs, glass jars, various liquids (for example: vinegar, salt water, cola, corn syrup, oil, etc.) pencil and paper
- Gather materials and label jars.
- Hypothesize how liquids will change eggs.
- Fill jars.
- Carefully add eggs.
- Record observations each day.
- After 3-5 days remove eggs and observe changes. (Note: vinegar eggshell can be removed gently in cold water.)
- How did the changes line up with the hypothesis?
- As an extension activity, retry and add food coloring to show how deeply each liquid penetrates.
