Can you mix two liquids to make a solid that is insoluble? Yes, you can, and pupils see this as the lesson uses more than one combination of liquids to form a solid. Through two teacher demonstrations and a hands-on activity,...

Things are getting a little slippery in an inquiry-based lesson studying precipitates. Learners use soap and Alka-Seltzer tablets to create different mixtures with water. They then study the properties of the mixtures including their...

Precipitation reactions are always interesting. How about one that forms a precipitate using a gas? Chemists of any age will enjoy this twist on a standard solubility lab. Partners observe the lack of interaction between sodium...

Conclude this chemical change unit by having your class combine two liquids that result in formation of a precipitate. The learners discover that chemical reactions result in new materials. Make sure to consider all of the preceding...

Several factors affect the rate of a chemical reaction including temperature, surface area, and concentration. Using an experimental approach, learners explore the effect concentration has on this rate while maintaining consistency with...

Small groups place sand and ice in a covered box, place the box in the sunlight, then observe as evaporation, condensation, and precipitation occur. These models serve as miniature water cycles and demonstrations of the three phases of...

Complete teacher narrative and presentation slides for teaching about Earth's water make up the bulk of this lesson. Embedded within the slide show, you will find videos about the water cycle, keeping track of the limited supply of fresh...

Can your pupils build a roof that stands the test of time? Use an insightful engineering design project to highlight both materials science and architecture. Scholars either team up or work as individuals to design, create, and test a...

Explore the water cycle in all aspects with a resource packed full of activities and lessons. The 37-page packet comes with vocabulary, a game, writing prompts, printables, and opportunities to journey through the stages in the water...

Young water cycle enthusiasts discover the water they have been using has been cycling around the earth for billions of years. Through presentations, learners will understand that water has three states and how these forms...

Take young scientists on a trip through the water cycle with this interactive science activity. After setting up a series of ten stations representing the different places water can be found, children use the included printable dice...

Dive into an exploration of the water cycle cycle with this simple earth science lesson. After first discussing where rain comes from, young scientists define the terms condensation, evaporation, transpiration,...

Young chemists love it when colorful solid products appear in a reaction vessel! Scholars discover the products that form during halide ion tests through a hands-on activity. Users go online and apply chemistry knowledge and reasoning...

How many jackets do you need to stay warm and climb Mount Everest? An informatie resource covers the topic of Mount Everest, the resource helps young scientists discover the difference between climate and weather. Activities include...

How do clouds form? Learners demonstrate the formation of clouds and the water cycle by testing four different setups in a plastic bottle. They identify the key components of a cloud to help them understand the process of cloud...

After reading an informational text detailing the ins and outs of snowflakes, scholars draw their own special design then work cooperatively to role play a snowman building scenario. 

Explore the amazing power of glaciers with a hands-on earth science experiment! After first learning basic background information, learners go on to create their very own chunks of frozen water and gravel in order to...

Tree rings are slightly thicker on the south side of the tree because it receives more sunlight. Part two in a series of five lessons helps learners analyze tree rings to determine the environmental conditions that caused size...

Climate change affects even the largest and intimidating of landforms—even Mount Everest! A resource helps teach learners the connection between global climate change and its effects on Earth. Activities include videos, class discussion,...

A hands-on activity helps learners explore the water cycle. After discussing how they use water, classes discuss water pollution and then move into a simulation where 20 pupils move through the water cycle based on description cards. 

Where does the water we use come from? To understand the concept of a watershed, class members study the water cycle and then engage in an activity that simulates a watershed.

Examine how pollution makes its way into an ocean with help from a model watershed. Scholars use household items to recreate a mini-watershed, equipped with pollutants, that when mixed with rain drain into a model's body of...

Do you think chromatography paper suffers from separation anxiety? Young chemists make soap, slime, silly putty, and experiment with chromatography in this lesson. The material includes clear instructions for each experiment along with...
