In this solutions worksheet, students compare situations that increase or decrease the solubility of a solute. Students describe how surface area, stirring, and temperature can increase the rate of dissolving a solute. This worksheet has...

In this solubility worksheet, students test a variety of polar and non polar substances to determine which ones will dissolve in vegetable oil and which ones will dissolve in water. Students collect data and answer 2 questions about...

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

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

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.

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...

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...

Course identification information is included in the upper left corner as well as within the title of this worksheet. If you overlook or remove that information, you are left with a tremendous college biology assignment. There are only...

Learners investigate how water passes through cell membranes. In this biology lesson, students differentiate osmosis and diffusion. They illustrate the movement of water in both processes.

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...

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...

Students explore solubility of gases in water, Henry's Law, LeChatelier's Principal, and supersaturation of gases in water.

Students separate a mixture of pigments with ion exchange chromatography and predict whether the ion-exchange matrix is positively or negatively charged based on the type of pigment bonded to the matrix.

In this Chemistry 1A learning exercise, students review, molecular weight, solubility, endothermic reactions, and number of protons, neutrons, and electrons for elements. Students review Lewis Structures and how to predict the amount of...

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...

Students explain how melting glaciers affect global warming. In this earth science lesson, students investigate the change in ice density as it melts. They discuss the human and environmental impact of rising sea levels.

In this biotic and abiotic factors worksheet, students complete 20 various types of questions related to biotic and abiotic factors. First, they write the vocabulary word that best completes the sentence. Then, students state an example...

In this solubility and intermolecular force worksheet, students are given 26 clues about forces between molecules such as hydrogen bonds and London forces and about solubility of solutions.

Students observe demonstrations of exothermic and endothermic reactions and determine the changes that take place in a chemical reaction. Students observe four demonstrations showing entropy, attraction of molecules due to polarity,...

In this aqueous solutions worksheet, students will explore the characteristics of solutions, including the ability of different compounds to dissolve in the solutions. This worksheet has 10 true or false statements and 8 short answer...

Students examine amino acids and discuss the properties of side chains.  In this proteins lesson students demonstrate the foldings of peptides.

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...

Learners 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.
