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,...

It's time to increase the heat! Young chemists demonstrate heat transfer and heat capacity in an activity-packed lab, showing the transitions between solid, liquid, and gaseous phases of materials. Individuals plot data as the...

Explore terminology related to water droplets. The sixth installment of a nine-part series teaches young scientists about wetting and contact angles between water droplets and surfaces. It also distinguishes between hydrophobic and...

We use basic units of measurement to break down things and communicate clearly. The first lesson in an 11-part series teaches the proper way to measure various items. It starts simply with measuring the dimensions and areas of geometric...

Discuss Archimedes' Principle and fluid forces with your young scientists as they describe the relationship between mass, volume, and density during a series of engaging activities. They use the Participle Theory of Matter to explore the...

Physical science investigators mix sugar and food coloring into different cups of water and cooking oil to compare how the solid and liquid behave in each. As the introduction to this unit on dissolving, it is relevant.

Titration experiments don't have to give your high schoolers a stomachache. Study the ways to titrate an acide with a base in an engaging science experiment, which involves creating solutions and performing titrations. Pupils...

Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Some of kids' favorite toys are the products of science experiments. Scholars follow precise measurements to mix and create their own slime and Play-Doh. They observe the changing textures and the chemical reactions throughout the...

Are serving sizes for different foods always appropriate for what you need? In this hands-on activity, learners work in groups to estimate what one serving size of various foods are, and then evaluate their hypotheses by measuring...

A half-page chart compares the properties of metals and nonmetals. Properties include appearance, melting and boiling point, density, strength, malleability, ductility, heat and electrical conductivity, and the nature of their oxides....

Your chemistry class is sure to love this experiment on column chromatography, as demonstrated with chalk sticks and felt tip markers. Pupils use sidewalk chalk (another inexpensive form of chalk stick) to demonstrate adsorption and the...

Stir chocolate drink mix into hot and cold water to see if there is a difference in how quickly it dissolves. Number three in a six-lesson unit on dissolving, this installment investigates the effect of temperature. If you consult the...

Love is in the air? Wrong — nitrogen, oxygen, and carbon dioxide are in the air. The final instructional activity in the series of five covers the impact of temperature on gases. Scholars view a demonstration of gas as a type of matter...

Conclude this chemical change unit by having your class combine two liquids that result in formation of a precipitate. The learners discover that chemical reactions result in new materials. Make sure to consider all of the preceding...

In this elements worksheet, high schoolers complete a graphic organizer by comparing the elements' melting point, boiling point, density, and electronic configuration. Students determine the characteristics of Group 7 elements. This...

Cell size is limited by the surface area to volume ratio, but why is this true? Scholars measure the surface area and volume of cubes before placing them into liquid. After a set amount of time, they measure the uptake by diffusion for...

Students covert ethanol to ethanoic acid using a condenser for this oxidation reaction worksheet. They test the smell of the final product, add sodium carbonate, and test the product with indicator paper. They explain their observations...

In this elements worksheet, students complete a graphic organizer by filling in the symbol and atomic number for the given elements. Students plot a graph of melting point against atomic number. Students write the electron arrangements...
