Students conduct a hands-on activity to investigate salt concentrations in water and how salt remain after water evaporates. They can also do a Saltwater Painting to once again observe the evaporation. process.

What happens when solids are added to liquids? After reading an informative paragraph about solutions, learners answer six true/false questions regarding solutions, and what substances will dissolve into liquids they are mixed with. A...

How do scientists determine when a solution is fully saturated? Scholars address the topic as they observe patterns of precipitation in various concentrations of ions. Using a well plate, pipette, and common chemicals, they collect data...

A table of the physical properties of metals and non-metals opens this high-school chemistry handout. Also covered are the chemical properties of metals and non-metals, reactivity, and fossil fuels. There are no specific questions to...

Viewing this slide show prepares your chemistry scholars for chemical nomenclature. Specifically, binary hydrogen compounds and ternary compounds formed from oxyacids are dealt with. One highlight is a useful graphic organizer for naming...

Humans eat around 93,205 miles of DNA in an average meal. Scholars learn how to extract DNA from a strawberry using a presentation. It walks through each step and explains why the process works. Comprehension questions encourage...

What's in a cell, anyway? Kids read informational text on what makes up both animal and plant cells, including a page of vocabulary terms they will need to be familiar with (cytoplasm, ribosomes, vacuoles, etc.). Full-color images...

What occurs when a hydrate is heated? Lead your class in exploring the answer to this question as they investigate the properties of a hydrated compound. They heat copper(II) sulfate pentahydrate and evaporate the water...

Students determine the solubility of salt in water at three different temperatures and graph the results. They use the following skills: observing, inferring, and graphing.

For this outcome science 4 worksheet, students apply scientific knowledge to answer and calculate a variety of questions. Students research the answer to several questions using the websites suggested.

Here is a good learning exercise for 5th grade scientists. In it, they look at a bar graph that shows the freezing point for a variety of liquids. Then, they are given a scenario of a certain liquid melting and freezing, and must...

Students analyze density. In this density lesson, students experiment with floating an egg. Students discover that salt added to water changes the density of the water allowing an egg to float.

Although there are only six questions on this chemistry handout, it makes a thorough review of solutions. Novices explain why a compound is not an electrolyte, identify types of compounds, and calculate moles, grams, and molalilties in...

In this chemistry worksheet, learners write the balanced equation for the reaction and rearrange the potassium expression to solve for x. Then they determine how many grams of silver chromatic can dissolve in a specified amount of sodium...

For this metric units and properties worksheet, students determine the proper metric unit given a variety of measurements for specific items. They also identify chemical and physical properties and chemical and physical changes.

Help your students write descriptive lab reports! Designed for ESL students but useful for mainstreamed kids as well, the activity prompts students to think of substances that match twenty given adjectives ("salt" for "soluble," for...

Even though they were written for upper-level high schoolers or college pupils, the labs herein are possible to use even in middle school. In the activity, kids observe osmosis in both potatoes and elodea plants, then record and graph...

Elementary schoolers who are learning about filtration and mixtures could use this worksheet to gain practice in filtering techniques. In it, they are asked how to manipulate a container in a way that would lead to properly filtering...
