Students examine the rule of "like dissolves like." They define and describe solutions and solubility models on molecular liquids, ionic solids, and molecular solids.

Students explore the effect of chemical erosion on statues and monuments. They use chalk to see what happens when limestone is placed in liquids with different pH values. They also discover several things that engineers are doing to...

Middle schoolers use the scientific method to discover the role of a candle's wick and how radiation allows candle wax to change from solid to liquid to gas. They work in small groups to use the steps of the scientific method approach in...

Eighth graders analyze questions posted on a large poster in the room and work in groups to record their response to the question on paper, rotating to the next question after two minutes have passed. They review the characteristics of...

Students convert Celsius to Kelvin temperature. Students conduct three lab experiments, gas law simulations using Internet applets, lectures and demonstrations. The Laws included are Boyle's, Charles, Combined Gas, Ideal Gas, and Gram's...

Fourth graders make observations of the reactions that happens between calcium carbonate and various liquids. During the experiment the students determine if there is a chemical change, a physical reaction, or no reaction when they mix...

Students work with measurements of length, area, and volume capacity of a liquid. They watch a teacher demonstration of both English and metric units before they estimate and take actual measurements of assigned items a three different...

Students move with control in general space. They move with three different spatial distances and tempi. Students demonstrate understanding of the distance and speed of particles in matter: solid-close and slow; liquid-medium distance...

In this lesson, learners investigate the phenomenon of sound! Students compare and contrast how sound travels through solids, liquids, and gases. They explain how length and thickness affect sound. Learners know the difference between...

In this ESL weights and measures vocabulary instructional activity, students place the names of 14 measurements into the proper column. They sort the words under the headings; small distances, long distances, temperature, area, weight,...

In this chemical compounds worksheet, students identify the types of intermolecular forces present in the given substances, calculate the heat required to convert a liquid to gas, and explain the ideal-gas law. This worksheet has 5...

Students study effervescence. In this hands-on science instructional activity, students apply the scientific method as they complete an activity regarding the presence of bubbles in liquids.

Students identify acids and bases. In this chemistry lesson, students use red cabbage juice as an indicator of whether the liquid is an acid or base. Students discuss the results.

Students examine states of matter. In this solids and liquids lesson, students conduct a scientific investigation that requires them to make oobleck and record their observations pertaining to it.

Students create a model of a glacier and observe how it moves. In this landforms lesson, students learn what a glacier is, build a model glacier and observe how it moves in a manner that more closely resembles a liquid than a solid.

Systematically diluting a full-strength sample of food coloring is meant to help earth scientists understand concentration in parts per million. While they will enjoy the lab exercise, it might be a challenge to help them relate it to...

Seventh grade scientists weigh in on the concept of density. In a nutshell, they participate in the following activities: Measurement of the mass and volume of fruit in order to compare densities Measurement of the mass of oil and water...

Students investigate the process of glass blowing.In this simulation of glass blowing experiments students experiment how glass is formed and why not all glass is the same.

In this math worksheet, students practice finding the 15 vocabulary terms in the word search puzzle. Word recognition is the focus of the activity and spelling.

Students will make a lava lamp. In this density lesson, students will combine water and oil and make observations, then add salt to the oil and observe the oil sink, then float again when the salt dissolves in the water.

The earth is a delicate and fragile thing; Why not engage your class in a craft project that will make them aware of our environment? Earth Day is celebrated as recycled materials are used to create earth window hangings. Crayons are...

Young chemists create gold nanoparticles as they learn to measure accurately with the metric system. They create an advertisement for the application of nanotechnology to complete the first lesson in a series of six.

We taste with our taste buds, so why do flavors change when we have a stuffy nose? Scholars experiment with taste testing while holding their noses and then while smelling. They record their observations in pairs and come together to...

Bubbles are not always trouble. Pupils investigate surface tension in water and bubble mixtures by blowing bubbles and recording observations. Learners then create bubble wands of different shapes from pipe cleaners and observe the shape...
