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...

Where does the pop in pop rocks come from? An engaging activity asks scholars to measure the amount of carbon dioxide in a package of Pop Rocks candy. Learners dissolve the candy in water and use the solubility of CO2 to determine its mass.

How much does your class know about the relationship between climate change and carbon dioxide? Science scholars explore the nature of greenhouse gases and rising ocean temperature through demonstrations, research, and experiments. The...

When you need a review instructional activity for your AP biologists on water and nutrient transport in plants, this one is for you! From the simple stuctures involved to the complex mechanisms that make it happen, the details of...

It is recommended that you conduct this fabulous experiment as a whole-class demonstration. Collect air samples from the environment, human exhalation, and car exhaust, then compare them for carbon dioxide content using bromthymol blue...

Young scientists discover that air is a mixture of different gases - mainly nitrogen and oxygen. The properties of some of the other gases found in oxygen are listed in a table, then learners must decide which one of those gases is...

For this gases worksheet, learners conduct an experiment to produce 2 different gases and use standard tests to identify each gas. This worksheet has 14 short answer questions.

For this thermal decomposition of calcium carbonate learning exercise, students perform three experiments on calcium carbonate, make observations, and write the equations for each reaction. Students explain in detail what happened at...

Yeast and sugar go beyond the pantry and into a fuel experiment. Use these common baking ingredients to assist your class in creating ethanol, a natural fuel. Pupils observe the process and gather information to elaborate...

In the summer of 1815, snow fell every month in New England. Was this related to the volcanic eruption of Tambora in Indonesia earlier in the year? Young scientists design their own experiments to research the long-term effect a volcanic...

Biology classes will bubble with excitement as they complete this assignment. Beginning with an informative overview of cellular respiration and fermentation processes, the highlight comes as an experiment in determining the rate of...

In this science worksheet, students explore two experiments involving yeast. Students discover that yeast grows faster at room temperature than at hot or cold temperatures.

Budding biologists often ask how scientists know what they do about different topics. In the lab described here, they have a chance to find out first-hand about the requirements for photosynthesis. Three sequential investigations are...

In this Earth's atmosphere worksheet, students observe the effects of air pressure using an egg. They describe what happens to the egg and what makes it do what it does. Then they determine how to get the egg out of the bottle opening at...

How does energy from the sun make plants grow? Scholars move step by step through the processes that promote plant propagation during a detailed lesson. The resource illustrates ADP production and hydrolysis, then allows learners to...

This well-organized lab activity introduces earth science pupils to the greenhouse effect. They will set up two experiments to monitor temperatures in an open jar, a closed jar, and a closed jar containing water. Ideally, you would have...

A thorough investigation of cell transport is provided when completing the assignment. The first half requires biology class members to answer questions about diffusion and osmosis with the aid of diagrams. Then they fashion an...

For this photosynthesis worksheet, students use a textbook to research the different scientists involved in the discovery of the process of photosynthesis. This worksheet has 31 fill in the blank questions.

Take a look at climate change from another angle. Readers learn about the MISR instrument on the Terra satellite and how it studies Earth. Pupils experience how the multiple cameras give scientists multiple views so they can better study...

Plants need sun and water to survive. Let kids discover these facts by reading a block of informational text and considering a scientific quandary. They read the text, then use the information to complete a two-part question about plant...

Explore the respiratory system with a model. First, pupils build a set of lungs to experiment how they inflate and deflate. Then, they delve deeper into the topic with a web quest to discover new information about the nose, trachea, and...

In this measuring lung volume and capacity worksheet, students perform several experiments testing for exhaled carbon dioxide, measuring lung volume, and measuring lung capacity.

If you have elodea and snails in your classroom aquarium, or if you have access to a pond with these organisms, your young biologists can set up a controlled experiment to determine how certain ecosystems respond in light and dark...

In this chemical reaction worksheet, students experiment with soda and Mentos candy to observe a chemical reaction. Students describe the reaction, identify the investigation as descriptive or qualitative and make a prediction if the...
