Acid Base Neutralization
In this neutralization worksheet, students determine the concentration of solution if neutralized by a certain amount of another solution. This worksheet has 7 problems to solve.
Curated OER
Physical and Chemical Change
Students study the differences between physical and chemical changes. In this physical and chemical activity students complete several labs to help them to see the differences between these changes.

Vision Props of Signed Numbers
Students explore the concept of titration. In this titration lesson, students observe acid and alkaline reacting. Students discuss pH factor, measuring acidity, neutrality, and alkalinity of liquids. Students put the pH of liquids on a...
Curated OER
Effect of Concentration of the Reactants
Students experiment to determine the effect of the frequency of collisions between atoms or ions of the reactants. They investigate the rate at which aluminum replaces hydrogen from a solution of hydrochloric acid.
Curated OER
Introduction to the Digestive System
Students describe the digestive system and simulate what happens to food as it passes through. They use an apple, tubing and hydrochloric acid to simulate the digestive process.
Curated OER
The Need for Normality
Students investigate the need for measuring concentrations in normality in titrations. In this titrations and normality lesson, students perform titrations and use different indicators to show they change colors at different pH values....

Hatching Chickens
Students observe caring for eggs and chickens. In this hatching lesson students brainstorm what they know about chickens and carefully watch what happens.
Santa Monica College
Mole Ratios and Reaction Stoichiometry
Stoichiometry sounds complicated, but it really means the study of the amount of substances involved in a reaction. The sixth lesson in an 11-part series has scholars use stoichiometry to find the theoretical yield of a reaction. Then,...
Nuffield Foundation
Effect of Size on Uptake by Diffusion
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...
Nuffield Foundation
Investigating Osmosis in Chickens' Eggs
You might not be able to learn through osmosis, but you sure can observe it! Scholars observe and measure osmosis using chicken eggs. They control for multiple variables to determine which variables have an impact and how the impact...
Nuffield Foundation
Investigating Factors Affecting the Breathing Rate of a Locust
Do animals breathe faster when given more oxygen or more carbon dioxide? Young scientists observe the respiration rates of locusts under a variety of gas concentrations to answer that very question. They collect data, analyze the...
