A list of vocabulary terms relating to the cell membrane tops this page. Biology learners show what they know by using the words to write a paragraph about cell membrane structure and function. Consider using this as a quiz or part of a...

In this intermolecular forces worksheet, students read about the two types of forces: dispersion forces and dipole-dipole forces. Students then complete 2 problems based on what they read.

Your students will love this PowerPoint! Great visuals will support understanding of membrane proteins, cell membranes, active transport, and diffusion. There are a lot of details on each page and all are relevant. The presentation could...

Alia-Seltzer tablets cause a very obvious chemical change, but do they also cause a temperature change? Each class member explores hot/cold packs, discussing how these temperature changes occur. Groups then design and carry out their own...

The first golf balls were made of wood and would only last for a few games. Modern golf balls last a lot longer but they don't float. The presentation provides the directions for a lab to determine the minimum amount of salt needed to...

What an exciting lab experiment to conduct with your high school chemistry class! Crystals are formed naturally in the environment. However, allow your blossoming chemists to create their own unique crystals using alum and...

What common chemical includes safety warnings for being harmful if swallowed or inhaled, causes serious eye damage, and needs to be cleaned up immediately if spilled on the floor? Surprisingly, the dangerous chemical turns out to be...

Just as skin covers your body limiting what can go in and out, plasma membranes cover cells to do the same. Scholars begin with a presentation that gives overview of the structure and function of plasma membranes. Then, they learn how...

Young scholars observe how salinity affects the time it takes water to freeze. They participate in an experiment to determine that ice is essentially salt-free whether formed from fresh or salt water

A fantastic presentation with great images should improve student understanding of lipids and their involvement in the body.  The chemistry of different fats, phospholipids, and steroids are explained. Additionally, the specific...

In this chemistry worksheet, learners fill in the chart for question one. The chart is filled out examining the mass, protons, electrons, and neutrons for specific atoms.

For this solutions, suspensions and colloids worksheet, students use diagrams to show how particles are different in each of these mixtures. They also distinguish between characteristics of each of these types of mixtures and categorize...

A fantastic presentation with great images should improve student understanding of lipids and their involvement in the body.  The chemistry of different fats, phospholipids, and steroids are explained. Additionally, the specific...

I can move about freely, but you cannot. The class models the movement through cell membranes by way of passive and active transport. Members of the class play the roles of various proteins, atoms, compounds, and cell actions and mimic...

Lost an electron? You should keep an ion them. Young chemists learn qualitative analysis in the second lesson of an 11-part chemistry series. After observing reactions of simple salts, the teacher provides pupils with unknown...

If the delay between a sound and its echo is less than 1/10th of a second, the human ear can’t distinguish it. Through the use of a Slinky, rubber band guitar, and straws, scholars explore where sound comes from and how it travels....

Marine biologists research sea ice communities. Assign some groups to construct paper models of sea ice communities in winter, and some to construct models of them in summer. The lesson is simplistic, but the Internet resources provided...

Vocabulary that is essential to this topic is introduced and defined at the start of this slide show. The following slides help students understand proteins and their use and involvement in everyday substances. Great diagrams help your...

For this crystals worksheet, students complete a graphic organizer by filling in the characteristics of the different crystal types including melting/boiling point and electrical conductivity.

Students explore visosity of matter. They run tests of various liquid substances to observe and compare rates of flow of different substances. In addition, they relate viscosity to distance travelled by sample substances.

Students determine that some liquids are able to evaporate more readily than others. They create a balance using cups and a ruler to determine which end of a strip dipped in alcohol or water evaporates the fastest, hence loses the most...

In this chemistry of life worksheet, students will review key terms of plant cell structure and chemistry by reading 13 clues to complete the puzzle. Word bank is included.

In this solubility worksheet, students identify substances as either ionic or molecular, define saturated solution and solubility, and calculate concentration of solutions. This worksheet has 7 short answer, 5 fill in the blank, and 27...

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