Kitchen Chemistry: Weather Science

Kitchen Chemistry four seasons winter polymer snow girl face reaction surprise

Today, you can do these four simple weather science activities with your kids, and they will get to experience the four seasons right from their own kitchen! We have advice about how to get started, and how to tailor this activity to children of different ages.

Weather Science for the Four Seasons

My science students were always fascinated by weather. On rainy days, they loved pressing their faces against our classroom windows and watching the raindrops fall from the sky. Because they were so curious about this topic, I decided to design four simple weather activities, each linked to a different season:

Spring—Rain in a Jar

Summer—Sun-Stained Art

Fall—Cloud in a Jar

Winter—Polymer Snow

Materials for Weather Science Activities

These weather science activities can easily be done with common materials. Here is a list of the basic materials you will need:

kitchen chemistry weather science four seasons materials needed for activity kids learning at home

Spring: Rain in a Jar—Materials

Clear glass jar or cup

Extra bowl or cup

Water

Shaving cream (foam, not gel)

Food coloring

Dropper/pipette (alternatively, a spoon can be used)

Summer: Sun-Stained Art—Materials

Black or dark colored sheet of construction paper

Objects of various shapes (ex. leaves, small toys, utensils)

Repositionable glue, optional (find it here)

Fall: Cloud in a Jar—Materials

Clear glass jar or cup

Black paper

Scissors & tape

Warm water

Ice cubes

Metal bowl

Matches

Winter: Polymer Snow—Materials

Snow powder (find it at Amazon, Walmart, or Steve Spangler)

Water

Cup

Procedures for Weather Science Activities

Once you have gathered your materials for an activity, here are the procedures for each season.

Spring: Rain in a Jar—Procedure

Fill the clear glass jar ¾ full with water.

Spray shaving cream on top of the jar covering the water to form your “cloud.”

In a separate bowl/cup, mix water with a few drops of food coloring.

Using the dropper, drop the colorful water onto the shaving cream “cloud” 1 drop at a time.

When the rain cloud becomes saturated enough, watch as the “rain” comes breaking through the “cloud!”

Note: If you do not have a dropper or a pipette, a spoon can be used to pour a few drops at a time of the colorful water onto the shaving cream “cloud.”

Summer: Sun-Stained Art—Procedure

Collect some objects around the house or pieces of nature from outside.

Place the sheet of dark colored construction paper in a very sunny location outside.

Position your objects on the paper. If you are using light objects, like flowers & leaves, use small rocks to hold them in place.

After 3–5 hours, remove the objects from the paper. You now have custom made art!

Alternative: Glue your objects to the paper with repositionable glue. Tape your paper up in a sunny window. After a few days, take your paper down and remove the glued objects.

While you are waiting for the art to appear, you could also make solar oven s’mores.

kitchen chemistry weather science fall cloud in a jar

Fall: Cloud in a Jar—Procedure

Cut the black paper to fit halfway around the jar, leaving about one inch of space at the bottom of the jar. Tape it in place on the outside of the jar.

Add about two inches of warm water to the glass jar.

Fill the metal bowl with ice cubes.

Light a match and hold it inside the jar for a few seconds and then drop it into the warm water.

Quickly cover the jar with the bowl of ice.

Look into your jar from the open side and observe what is happening. To see the cloud even better, turn off the lights and shine a flashlight into the jar towards the black paper.

After watching your cloud for a while, you can take the container of ice off of the jar and watch your cloud rise up and disappear!

kitchen chemistry weather science winter polymer snow

Winter: Polymer Snow—Procedure

Measure 1 teaspoon of snow powder and add it to the cup.

Pour 2 ounces of room temperature water on top of the snow powder in the cup.

Watch & observe the snow created in front of your eyes!

Ask your child to list the similarities and differences between the polymer snow that they created and the real snow that falls from the sky.

Note: Check the ratios of snow powder to water on your snow powder container as they may be different from what is listed above.

Adapting Weather Science Activities for Preschoolers

For young children, I always like to begin science experiments with a story time. Four Seasons Make a Year by Anne Rockwell is one of my favorites for this set of activities, but there are many other good reads that explore the seasons. Ask your child to describe what the weather looks and feels like in each season. Let them know that today they are going to explore the weather of the different seasons with science experiments. Encourage them to make observations and ask questions about what they see, hear, and feel along the way!

Presenting Weather Science Activities to Grade Schoolers

Children in middle grades are often fascinated by clouds. They look like giant puffs of floating cotton candy, after all. That is why I especially like the Spring and Fall activities for children in this age group.

In the Fall activity, the water in your jar simulates bodies of water on Earth. Ask your child to name some bodies of water—ponds, lakes, oceans, etc. When the water molecules get extra energy from a heat source, in this case the match, they turn from liquid to gas, forming what we call water vapor. Ask your child where they think the heat source in nature comes from? Hint—they saw its powerful effects in the Summer activity! As the warm air containing water vapor rises, it cools and the water vapor condenses to form tiny liquid droplets, which cling to dust particles in the air. When billions of droplets come together, they form a cloud!

Now what happens when the cloud gets too big? As more and more droplets come together in the cloud, the droplets begin to merge forming even bigger droplets. When the droplets become too heavy to stay suspended in the cloud, what do you think happens? Have your child think back to Spring activity to make the connection.

Extending the Activity for Upper Schoolers—Chemistry

While the Winter activity is fun for all ages, it provides a great chemistry extension for your teens! The powder you have is something call a “superabsorbent polymer,” or SAP for short. SAPs can absorb and retain extremely large amounts of liquid compared to their own mass. Based on the properties of SAPs, ask your teen to think of some real world applications for them. Hint: if you have a baby brother or sister at home, that may give you a clue!
