In this conservation of mass learning exercise, students experiment with vinegar, baking soda, a balloon and a flask. They compare the mass of the closed system of reactants before the experiment to the mass of the products after the...

Ice core samples give scientists access to climates of old—those from more than 800,000 years ago. Through an analysis of various temperature graphs from ice cores, tree rings, and weather stations, scholars compare historical climates...

Forests, through sequestration, capture excess carbon dioxide in our atmosphere and store it, aiding in climate change. The third installment in a four-part series on how climate impacts forests explores carbon sequestration....

Manage your money with change purses and piggy banks. Once they match different coins to corresponding price tags, first and second graders add the amounts of change in each illustration. For extra practice, bring in small items for kids...

Teachers demonstrate water runoff on a hill and its effect on soil erosion. Pupils observe as the instructor changes the steepness of the hill and see whether vegetation covers the soil. Learners then use their observations to make...

Pre-assessments are great to help teachers determine what information their classes lack, what misconceptions they have, and how in depth to teach specific concepts. The first in a five-part series is a pre-assessment of middle...

Prove the Law of Conservation of Mass through a lab investigation. A well-designed lesson asks groups to combine materials and monitor indicators for chemical reactions. Measuring the mass of the reactants and products allows individuals...

Statistically, waste may become a problem in the future if people do not take action. Using their knowledge of statistics and data representation, pupils take a look at the idea of waste generation. The four-part unit has class members...

Are the Arctic ice caps really melting out of existence? Junior climatologists examine the statistics of ice decline through four math-based lessons. Each activity incorporates data, climate information, and environmental impact into an...

Winter weather offers a great opportunity to teach young scientists about the states of matter. This activity-based lesson includes a range of learning experiences, from experimenting with the rate at which ice melts...

Some chemical reactions produce heat, but what is really going on? Lesson focuses on the concept of energy changes, both exothermic and endothermic. Scholars perform multiple experiments, hands-on activities, and view videos of the...

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...

Your class will definitely get a charge out of an electric interactive! Show young scientists what really happens when you place a wand near a Van de Graaff generator using a simulation. Pupils add varying amounts of negative charge to...

This activity will not only get your youngsters moving, but will also help them to develop focus and attention to detail! The game can be played both indoors and outdoors, and involves learners taking turns to decipher who is leading the...

It's all about lines when going around. Pupils graph the relationship between the length of a side of a square and its perimeter. Class members explain the origin in context of the side length and perimeter. They compare the graph to the...

Simple doesn't mean useless. Individuals learn how simple machines benefit the user by changing the amount of effort. A seven-lesson unit begins with an overview of simple machines and then incorporates activities that allow the user to...

Where did the water go? Learners conduct an experiment to see how the difference in temperature affects evaporation rates. Scholars continue to investigate evaporation by comparing water and alcohol evaporation rates. Pupils experiment...

How do astronauts know how to live and work in a weightless environment? It doesn't come naturally! Junior physicists conduct experiments to examine the link between buoyancy and microgravity. Each activity illustrates a different aspect...

Discover the joy and excitement of improving your math fluency through four different puzzles. Combine those with 25 different ways to represent numbers and you have hours of enjoyment that can be fun outside of the classroom as well.

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...

Now that learners have been exposed to chemical changes, they learn that some take in heat and therefore, decrease in temperature. The same reaction that they have been investigating between baking soda and vinegar is revisited,...

Students find the density of diet soda and regular soda. In this density lesson plan, students measure the mass of a graduated cylinder with 10 different volumes of each soda. They find the mass of the liquid alone and use the volume to...

Getting back to the beginning of the unit, learners use reactions with red cabbage juice to determine if solutions are acidic, neutral, or basic. This is a straightforward and classic investigation, but what you will appreciate is the...

Students perform an experiment to measure the density of tap water vs. salt water.
