Grow a Bean Plant

Growing a bean plant is a great science experiment for kindergarteners. It is a simple, yet fascinating process that young children will enjoy. Begin by having the children soak several small, dry beans in a bowl of water overnight. The next day, place several soaked beans on a damp paper towel and then fold the paper towel to form a pouch. Place the pouch inside a clear plastic bag and seal it. Place the bag in a warm, sunny spot and watch as the beans begin to sprout and grow. Have the children check on the beans daily and watch as the roots and stems grow, and eventually, the leaves and flowers. Once the plant has grown, have the children transfer the plant to a pot and watch as it continues to grow.

Make a Rainbow

Making a rainbow is an excellent science experiment for kindergarteners. It encourages the children to observe and explore the colors of the rainbow and how light refracts. Begin by cutting a white paper plate into a rainbow shape and give one to each child. Set up a lamp in the middle of a room and have the children place the rainbow cutouts in the path of the light from the lamp. As the light passes through the rainbow cutouts, the children will observe the colors of the rainbow. They can also explore the colors of the rainbow by twisting and turning the cutouts in the light.

Create a Volcano

Creating a volcano is a fun and exciting science experiment for kindergarteners. To begin, have the children make a volcano out of clay and paint it to look like a mountain. Place the volcano in a bowl and fill it with baking soda. Next, fill a cup with vinegar and pour it over the baking soda. As the baking soda and vinegar mix, they will create a bubbling reaction, which will create a “lava” flow from the volcano. The children can also add a few drops of food coloring to the vinegar to create a colorful “lava” flow.

Create a Cloud

Creating a cloud is another fun science experiment for kindergarteners. Begin by filling a jar with hot water and adding a few drops of food coloring. Place the jar in the freezer for a few minutes and then remove it. Have the children take a spoon and stir the hot water and food coloring. As they stir, they will observe a cloud form in the jar. This experiment teaches the children about how water vapor turns into clouds in the sky.

Make a Rainbow in a Jar

Making a rainbow in a jar is an easy science experiment for kindergarteners. Begin by filling a jar with water and adding a few drops of food coloring in each color of the rainbow. Have the children use a spoon to stir the water and food coloring. As they stir, the colors will mix together and create a rainbow in the jar. This experiment teaches the children about the colors of the rainbow and how they can mix together to create something beautiful.

Make an Egg Float

Making an egg float is another great science experiment for kindergarteners. Begin by filling a bowl with salt water. Have the children place an egg in the bowl and watch as it slowly begins to float. This experiment teaches the children about the density of salt water and how it can make objects float. They can also explore how different objects can be made to float by adjusting the amount of salt in the water.

Explore Color Mixing

Exploring color mixing is an exciting science experiment for kindergarteners. Begin by giving the children two cups of water and adding a few drops of food coloring to each cup. Have the children use a spoon to mix the food coloring into the water. As they stir, they will observe the colors mix together to create a new color. This experiment teaches the children about the different colors of the rainbow and how they can mix together to create new colors.

Make a Wind Sock

Making a wind sock is a great science experiment for kindergarteners. Begin by having the children create a wind sock out of construction paper. Once the wind sock is complete, have the children hang it outside in a windy area. As the wind blows, they will observe the wind sock move and sway in the wind. This experiment teaches the children about the power of wind and how it can move objects.

Make an Indoor Cloud

Making an indoor cloud is another great science experiment for kindergarteners. Begin by having the children fill a bowl with hot water and add a few drops of food coloring. Place the bowl in the freezer for a few minutes and then remove it. Have the children use a spoon to stir the hot water and food coloring. As they stir, they will observe a cloud form in the bowl. This experiment teaches the children about how clouds are created and how water vapor turns into clouds.

Create a Tornado in a Bottle

Creating a tornado in a bottle is an exciting science experiment for kindergarteners. Begin by having the children fill a bottle with water and add a few drops of food coloring. Place the cap on the bottle and then have the children shake the bottle up and down. As they shake the bottle, they will observe a tornado form in the bottle. This experiment teaches the children about the power of air and how it can create a tornado.
