Students investigate various chemical reactions when creating mixtures in ziplock baggies. For this chemistry lesson, students will recognize various chemical reactions and cite evidence. Safety and assessment strategies are included in...

Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

Learn about the factors that affect the way oxygen dissolves in salt water with a chemistry lab. After studying the molecular structure of water, young scientists figure out how aeration, temperature, and organic waste affect...

Test the levels of vitamin C in different juices. After a instructional activity on the importance of vitamin C in our diets, learners use titration to determine the vitamin C content in juice. They use their experience with the...

Learners explore atomic measurement in the first activity in a series of 36. Through readings, activities, and questions, classes review standard SI units, learn about Avogadro's constant, and use it to help them calculate moles. They...

For this metric system worksheet, students are given ten sets of measurements with metric units and they are to place each set of measurements in the proper order from the largest to the smallest based on the unit.

Young chemists grow ionic crystals, metallic crystals, and supersaturated crystals in three different lab experiments. Observing these under a microscope allows pupils to compare the various structures. 

Fifth graders examine the differences between chemical and physical changes. As a class, they are read a scenerio and determine whether it was deliberate act or not. In groups, they observe the changes of an alka-seltzer tablet and...

Students use graph paper to construct a graph and determine the slope of a straight line. They determine the weight (mass) of paper clips with a pan balance. Pupils weigh an unknown number of paper clips, and to interpret the graph to...

Students explore the energy changes from a liquid to a solid. They model the arrangement of a solid and the change in states due to changes in energy using desks and chairs. Assessment questions are provided in lesson plan.

Students explore the three main forms of matter: solid, liquid, and gas. They examine concrete examples of each, using their five senses and "experimenting" to find differences in them. They find pictures of each, cut them out and past...

In this nuclear chemistry worksheet, students determine the biological effects and the applications of nuclear chemistry. Then students use Einstein's theory of special relativity to complete 3 problems.

Aqua regia, or royal water in Latin, is a solvent that can dissolve solid gold and platinum into a solution. Activity nine in a series of 36 allows classes to learn, through readings and answering questions, what a solution is and the...

Students investigate what is wrong with the Rutherford atomic model. In this chemistry lesson, students answer questions about the atomic model after watching a video. They draw conclusions from the video and discuss how the atomic model...

Students explore latent fingerprinting. They observe a supervised demonstration of the process that real-life crime scene investigators sometimes use to identify latent fingerprints. In addition, they brainstorm ways to improve the...

For this petroleum chemistry worksheet, students review hydrocarbons which includes petroleum. Students understand the properties of petroleum and where it is found. This worksheet has 12 words in a crossword puzzle, 6 fill in the blank,...

Students explore chemical solutions. In this chemistry lesson, students investigate the relationship between three related experiments about solutions. Students determine variables that affect the chemical concentration of each solution.

Students explore the the legends and myths of the Orient, Africa, Europe, Asia, and the Americas in this six lessons unit. Different cultures and belief systems of the inhabitants of these areas are examined through storytelling techniques.

Learners recover latent prints by iodine fuming, cyanoacrylate fuming, and dusting with powder, after a lecture/discussion on fingerprinting techniques. They each provide a fingerprint for identification by another student. A database of...

Several slides compare different temperature scales. Thermal expansion, heat transfer, and Maxwell speed distribution are also explored. The last two slides seem unrelated to the topic of heat, but are easily left out of this otherwise...

Students examine containers and their capacity. They fill a one-cup measuring cup with water and pour cups of water into other containers. Through observation, students discover how many cups make a pint, and how many teaspoons make a...

If you know how to employ the exothermic reaction between hydrogen gas and oxygen gas to make a miniature rocket, then this worksheet is a fabulous lab sheet for your chemistry charges. First, they observe a spark in pure oxygen and one...

In this chemical change worksheet, learners conduct 4 experiments set up around the room. They follow the instructions at each station for each experiment and list the physical properties and observe any changes at each station. Students...

Learners analyze the amount of space required to pack round objects. In this geometry instructional activity, students practice using space economically by practicing packing spheres into beakers. They then translate this concept to...
