Here is the first of four experiments to differentiate among unknown liquids by their behaviors and properties. Pupils observe how different liquids respond to being placed on plastic and paper, and they take notes about their...

Learners will like making a liquid layer cake to investigate the relative densities of various liquids: water, oil, and corn syrup. They will also introduce a few solid materials to find out how their densities compare. Standing alone,...

Once investigators have learned how their mystery liquids interact with water during the preceding activity, they now use their observations to identify them. This is an ideal conclusion to the mini unit on the properties of water. 

Blue-tinted water is added to unknown liquids that have been tinted yellow to find out how they interact. This is a memorable activity that is part of an investigation on the properties of liquids, which is part of a unit on the...

Second of six lessons in a unit on dissolving, this one focuses on how sugar behaves in different liquids. Learners stir it into water, alcohol, and oil and make observations. This lesson can stand alone, but is best used as part of the...

During a unit on density, pupils ponder whether or not temperature affects this property. By carefully inserting blue cold water and yellow hot water into a room-temperature sample, they will see the answer. Make sure to have done the...

Each group talks about how to test unknown liquids based on their findings in the previous experiment. In this second of four activities, they test unknowns on wax paper, newspaper, and construction paper. As a stand-alone, this lesson...

Liquids are what's the matter with the lesson! Learners investigate properties of different liquids as they interact with various types of paper. They then use their observations to identify a mystery liquid to finish the sixth lesson in...

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...

It's in your destiny to study density! Young scientists conduct an experiment to study the relationship between weight and density. They compare weights of liquid samples of different substances and predict how their densities are...

Students describe properties of liquids and use descriptive language as a springboard to develop precise vocabulary for properties of liquids. They also use vocabulary as practiced with liquid-vocabulary card games. Finally, students...

Third graders experiment with common household liquids and solids. In this chemical reaction lesson, 3rd graders discuss phase changes and experiment to find other ways to create gases. They use water, vinegar, lemon juice, flour, baking...

Students review the vocabulary terms solid and liquid. They also review that adjectives tell what kind, which one, and how many. The teacher introduces a "Oobleck" after reading "Bartholomew and the Oobleck" by Dr. Seuss. The students...

Chemistry neophytes use a temperature probe to assess the change as five different liquids evaporate. The implantation section suggests that they take readings every five seconds for a total of four minutes. They graph the data, look up...

Yellow and blue make green in a colorful lesson plan on liquid solutions. The seventh installment of a 16-part Inquiry to Action series asks pupils to mix different-colored solutions and record their observations. They then use their...

Learners explore the concept of evaporation rates in this evaporation rates lesson. They will try to identify the chemical that began a fire, perform an experiment where they use the evaporation rates to determine the unknown liquid, and...

Use science to help you walk on water! Young scientists explore the properties of liquids including cohesion, adhesion, and surface tension. They use graphs to compare different liquids and make predictions about their molecular attraction.

Here's a tip: only one substance is commonly found as a solid, liquid, and gas. Learners use that knowledge as they investigate the properties of water in each state. They interact with water in each of its three phases and record what...

Students investigate the properties of plastic eggs filled with solids, liquids, and gases and use these observations to hypothesize whether a chicken egg is hard-boiled or raw.

Middle schoolers explore and identify phases of matter and compare the particle motion in solids, liquids, and gasses.

Third graders conduct an experiment. In this floating and sinking liquids lesson, 3rd graders discuss density and investigate it using syrup, vegetable oil and colored water. Students observe the results and complete a worksheet.

Students experiment with a variety of liquids to calculate density. In this integrated science and math instructional activity, students listen to a story in which the characters must prove and explain why 5 "mystery" liquids react in a...

Learners conduct an online experiment to discover what happens to solids, liquids and gases in different temperatures. In this states of matter instructional activity, students get into pairs and work in a virtual...

Students build an understanding of the properties of liquids and research the immiscible properties of different milks through group experiments. In this immiscible liquids experiment, students investigate what happens when certain...
