Chemical Fun
Fifth graders observe and conduct a variety of experiments to differentiate between physical and chemical changes. They mix cabbage juice with different liquids and record their observations on a chart. Students write down their...
Curated OER
Fun With Chemical Changes
Fifth graders observe and identify the differences between chemical and physical changes. In small groups they mix different substances together in glass beakers, and identify which had a chemical change, supporting their statements...
Curated OER
Oceanic Absorption- Oceanic Sequestration
Students examine the techniques that may be used to reduce carbon dioxide in the atmosphere. In this pollution lesson students simulate oceanic sequestration using chemistry.
Curated OER
An Introduction to Acids and Bases
Learners explore acids and bases. In this lesson about acids and bases, students do an experiment to test certain items to determine what they are. Learners use cabbage and litmus paper as indicators. Students understand how to sort the...
Curated OER
Trapping CO2
Students investigate climate change and how the properties of carbon dioxide and methane play a part. For this climate lesson students use a chemical reaction to trap CO2 and methane.
Curated OER
Mystery Powders
Fifth graders evaluate the physical properties of 5 powders. Each powder is subject to different conditions. They describe each observation as with a chemical change or a physical change.
Curated OER
Can Acid and Bases Remedy the Body?
Students experiment with acids and bases using technology-based "probe-ware", computers, and household products in this exciting biology/chemistry instructional activity. The instructional activity was written for an advanced 6th grade...
Curated OER
Introduction to Gases
Students are introduced to gases. In this science lesson plan, students demonstrate that gases are a state of matter, generate a number of gases, discover some properties of gases, compare some of the properties of different gases, and...
Curated OER
A Very Simple Conductivity Meter
Students investigate the hardness of different water samples using the conductivity meter. In this chemistry lesson, students build their own meter following specific procedures. They identify an unknown sample of water.
Curated OER
Amylase Enzyme In Saliva
Students test for amaylase enzyme in a variety of substances. Student pairs perform a series of tests to determine how long it takes the starch sample to change to sugar molecules and the blue color to disappear when various saliva...
Curated OER
Using Your Senses
Students use their senses to make observations. In this senses lesson plan, students investigate unknown substances by using their senses for observations. Students identify the number of the substances used, the color, the odor, the...
Curated OER
Kitchen Cleaners
Students, in groups, select two cleaning agents that they feel solves their cleaning problem.
Curated OER
Mystery of the Eleven Unknown Substances
Fourth graders identify eleven white substances that are commonly found in the household. They, in pairs, perform experiments on a variety of substances, and must identify them based on the reactions they observe.
Curated OER
A Very Simple Conductivity Meter
Learners conduct a simple conductivity meter to test the ionic or non-ionic nature of water samples including one from their home.
Curated OER
It's a Crash Test, Dummy
Students use the internet to research air bags in cars and trucks. In groups, they discover air bags history and the safety issues surrounding them. They create their own design of a new air bag and test it using a raw egg in...
