Liquids have many similarities, but their differences can set them apart. Using a student activity guide, learners conduct different property tests on water, oil, and syrup. They record their results and use them to rank the liquids by...

Work together to stay afloat. Using a paper boat, pupils connect properties of materials to their usefulness. They test different paper to determine how many pennies each boat will hold and learn that combining materials with different...

Storing food in plastic makes more sense than storing it in paper. Young learners research the properties of these materials along with aluminum foil. They then connect the properties of the materials to their usefulness by completing a...

Sorting objects by properties is a instructional activity in justification. Learners begin by studying different types of properties of materials, including those based on appearance and texture. They examine the properties of specific...

Uncover the building blocks of the universe as budding chemists explore atoms and molecules in an exciting inquiry-based activity. Investigators view an interactive video describing the chemical structure of six molecules. Using...

Don't be so dense! Using food coloring, pupils conduct two experiments with the difference in densities of hot and cold water. In the first experiment, learners add dyed hot and cold water into room temperature water and observe how the...

Soften up an egg. Learners use vinegar to test for calcium carbonate in an egg shell and an antacid tablet and compare the reaction with vinegar to the reaction with water. In a second experiment, class members break down an egg shell...

Here's an activity that will change how one sees color. Pupils try out an experiment on chromatography where they place a drop of food coloring on a coffee filter, add several drops of water, and watch the colors spread and separate....

Knowledge of acids and bases doesn't need to be a secret. Learners use red cabbage to create an indicator solution, then test how adding lemon juice (acid) and detergent (base) changes the color of the solution. They then use the concept...

Copying the comics couldn't be easier. A fun and simple activity has young scientists rub the back of a comic strip with a spoon to see if the ink will transfer to a white sheet of paper. They then repeat the experiment, rubbing...

It's there, even though no one can see it. Scholars create two different-sized parachutes out of shopping bags, then let them fall through the air. They should see that the larger parachute falls more slowly and interpret this to mean...

Sometimes liquids just don't get along together. A fun experiment has scholars determine whether various liquids dissolve in water. They pour isopropyl alcohol, vegetable oil, and corn syrup into cups of water to see which ones mix well...

Time for more candy! Learners view a video of a candy bowl where some of the candy is removed and more placed back. Scholars come up with questions about the scenario to answer and request additional information from the teacher. At the...

Wonder how many pieces of candy a teacher can eat. Pupils watch a video of candy in a bowl as some candy is removed to be eaten and others are added. Learners devise questions about the situation along with estimated solutions. Scholars...

Turn up the heat. Individuals conduct two experiments to observe the difference between heated water and air versus cold water and air. Using food coloring, pupils observe the movement of the molecules in the two temperatures of water. A...

Create a charge in the classroom. Using pieces of cellophane tape, a plastic grocery bag, and a balloon, learners investigate the effects of static electricity. Pupils create different charges in the materials and observe whether they...

Bring out some bubbly! Individuals perform the classic baking soda and vinegar experiment with a twist. Learners add a drop of dish detergent to make the bubbles last longer. They vary the amount of baking soda and vinegar in an effort...

Bubbles seem to come from nowhere. Pupils investigate the formation of carbon dioxide bubbles in sodas. By placing different objects, including candies, in the soda, learners observe the formation of tiny bubbles on the surface of the...

Where does the water come from? Pupils conduct an experiment to learn more about condensation. Scholars fill two cups with ice water and isolate one from the surrounding air. They then use a coffee filter to compare the amount of water...

Where did the water go? Learners conduct an experiment to see how the difference in temperature affects evaporation rates. Scholars continue to investigate evaporation by comparing water and alcohol evaporation rates. Pupils experiment...

Bring chemistry to life for scholars as they perform two tests to examine the unique properties of three liquids. Classroom investigators make observations, develop basic lab skills, and follow step-by-step instructions to compare water,...

It's about to become crystal clear! Learners compare and contrast three different types of crystal substances. First they observe their structure and then investigate how they interact with various substances.

Let the bubbles tell the story. Using a hands-on lesson, budding scientists learn how carbon dioxide in soda interacts with objects placed in the soda. The lesson explains how the gas adheres to the surface of the objects based on the...

Add a little heat to your science lesson. Young experimenters work to understand the chemical reaction taking place when a candle burns. They experiment with both oxygen and carbon dioxide to make conclusions about the reaction.
