How can radioactive decay help date old objects? Learners explore half-life and radioactive decay by conducting an experiment using pennies to represent atoms. Young scientists graph data from the experiment to identify radioactive decay...

Introduce your classes to a new world of mathematics. Pupils learn to call trigonometric ratios by their given names: sine, cosine, and tangent. They find ratios and use known ratios to discover missing sides of similar...

Rational expressions are just fancy fractions! Pupils apply fractions concepts to rational expressions. They find equivalent expressions by simplifying rational expressions using factoring. They include limits to the domain of the...

Investigate the application of vector transformations applied to linear systems. Individuals use vectors to transform a linear system translating the solution to the origin. They apply their understanding of vectors, matrices,...

In this language arts worksheet, students study 20 words in a word bank, then locate them in a word search puzzle. The words appear to be related to chemistry but the meaning of the title is not known.

Young scholars write a paragraph (complete sentences) which explains what they did in the lab.

Students work in small groups with a small set of 8 nuts and 5 bolts to assemble into combinations of 1 nut: 1 bolt, and 2 nuts: 1 bolt. They explore the outcome and discuss. Then a student mixes two clear, colorless solutions together...

Third graders view a demonstration of a teeter totter as a basis for assessing pre-knowledge of a lever. They create a KwL chart. Students work in small groups to conduct a variety of experiments. The first requires students to tie books...

Tenth graders distinguish between chemical and physical properties and changes in matter when given specific examples. They view a video of sports activities. Students chose their favorite sport and design an experiment to improve sports...

High schoolers investigate the mixing of light. They form a hypotheses to reason why color changes occur and they write conclusions and ask new questions arising from the investigation. Students identify the primary and complementary...

Students develop the concepts of flood stage, levees, floodplain, and the dynamics of river flooding. They construct river models and test various flow rates and volumes. This lesson has an excellent experiment for students to do.

Learners make "pets" of isopods (potato bugs) to determine their preferred environment and food sources. They record their results on a bar graph and in a scientific report.

Science equipment can be handy for math class, too. Scholars learn to solve one- and two-step linear equations by using the concept of a balance. They solve real-world problems in a variety of contexts by writing and solving linear...

Sixth graders study heat, temperature, and heat transfer. Using probeware, the teacher demonstrates boiling points. Students participate in experiments and record the beginning and ending temperatures and mass of objects. After...

Connect math with science! Pupils apply properties of Ohms Law as they solve problems and identify the inverse relationship of a function. They analyze the shape of the graph of an inverse function and use it to make predictions.

Tap into the competitive nature of teenagers as your class practices setting up and solving rational equations. This activity starts with a specific ratio of games won to games played, then asks how many more games must be played to...

In this algebra worksheet, students use the summation notation correctly as they solve problems. They define the integral of a function and solve problems involving i. There are 14 questions with an answer key.

Students measure, record, and graph the force of moving a block of wood along sand paper. In this friction lesson plan, students read a spring scale, collect data, construct a graph, and propose a model to explain how fiction works.

Learners examine seeds from various plants. In this science lesson, students cut open fruits and vegetables in order to see the seeds. Learners describe each type of seed and classify the seeds.
