Ice is nice, and its condition on the planet has a significant effect. Junior geoscientists experiment with ice melting in both water and on land to discover how each affect the rising sea level. This detailed lesson outline even...

Open this lesson by demonstrating the production of acidic carbon dioxide gas by activated yeast. Emerging ecologists then experiment with seashells to discover the effect of ocean acidification on shelled marine organisms. They measure...

Fourth graders expand their knowledge about how the physical properties of a substances can be changed. They are given multiple opportunities, using first-hand experiences and familiar objects in different contexts, to identify...

Students explore physical and chemical changes. For this chemistry lesson plan, students will go outside to observe changes seen in nature. Students will then work in the lab to identify changes at different stations prior to doing a...

Temperature rises and land disappears! Through a lab exploration, learners understand the effect of temperature increase on water similar to the effect of global warming on our oceans. As they heat the water in a flask, they measure the...

Plant respiration can be a difficult concept for young biologists to grasp; with a hands-on lab, learners can collect and graph data, then calculate the metabolism rate for the plants they studied. If you do not have a respirometer,...

All together now! Physical science pupils observe the effects of temperature and amount of substance on pressure and volume of a gas. The interactive resource guides learners through the Combined Gas Law, where they observe changing...

At some point, everyone has been under pressure—even Dalton! Explore Dalton's law of partial pressures with young chemists as they measure the volume of air extracted from a sample compared to its original volume. Class...

In this chemistry review worksheet, students identify chemical changes, isotopes, ions, and chemical bonds. This worksheet has 32 multiple choice questions.

Learners determine the heat of fusion of ice. In this heat of fusion lesson plan, students use a calorimeter to measure the molar heat of fusion of ice. Learners determine the heat required to melt one mole of ice using hot water and ice...

In this lab design and lab skills worksheet, learners answer questions about experimental design including finding variables, determining controls, and graphing data. They answer questions about microscopy and label the parts of a...

Eighth graders investigate the effect of temperature on the volume of a gas in a closed container. They measure the height of the water in their beaker/container, conduct their experiment, and create a graph to illustrate their data.

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

Snow, ice, and water are all composed of H2O. Does that mean they all have the same volume? Discover the ways that the densities of these substances determine their volumes, and how they change based on their current states of...

Learn about polymers while playing with shrinky dinks. Young scholars create a shrinky dink design, bake it, and then record the area, volume, and thickness over time. They model the data using a graph and highlight the key features of...

Using helium as an example of propane, physical science middle schoolers experiment with and graph the relationship between temperature and volume in gases. In a whole-class demonstration, they show how molecules behave under different...

Students calculate the SA/V ratio and volume of phenophthalien agar that are cut into different shapes. They then let ammonia diffuse into the various pieces of agar and determine the effect that SA/V had on the rate of diffusion.

Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions...

In this observing and identifying matter worksheet, middle schoolers use a cookie in a bag and list 10 different descriptions of the cookie. They draw and label their cookie and given the cookie in the bag to their teacher who mixes all...

Students determine the solubility product constant and the concentration of a hydroxide. For this solubility product lesson plan, students use a solution of calcium hydroxide to neutralize a known concentration of hydrochloric acid. They...

Students investigate mass-mass relationships in the lab. In this mass-mass relationship lesson plan, students mix sodium carbonate with hydrochloric acid to produce sodium chloride, water and carbon dioxide. Students use the amount of...

Laughter may be the best medicine, but aspirin is also important. Young chemists analyze aspirin tablets using titration in this lab experiment. They then repeat the entire experiment using a different aspirin brand. 

There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson of an 11-part series. They then determine the density of water,...

Students investigate density and salinity of water. In this density and salinity lesson plan, students find the density of objects and liquids and show the relationship between the salinity and density of water. Students add salt to...
