Curated OER
Space Shapes
Students read "Captain Invincible and the Space Shapes" by Stuart Murphy and view a PowerPoint presentation on shapes. They identify shapes presented in the book and then identify shapes found in their classroom.
Curated OER
Color Dots 3
Students make simple observations, test mixtures, and make generalized inferences from their observations. They observe bleeding of colored inks with water.
Curated OER
Pulse
Learners determine a baseline pulse rate then chart the changes in rate with exercise. They describe the changes and develop a rationale for their observations. The task assesses students' abilities to make simple observations, determine...
Curated OER
Swinging Observations
Students build a pendulum type swinging apparatus and make specific and selective observations using what they know about scientific observations. They look for regularities of movement, patterns, and systemic changes over time.
Curated OER
Rain Drops
Students examine drops of water on several materials used on the outside of buildings. They make selective observations on and compare plastic, wood, brick, metal, roof tiles and glass.
Curated OER
Irregular Fractals
Students study and research irregular fractals and construct a few based on their research. Students practice pattern recognition skills and plane geometry skills calculating dimensions on the Fractured Pictures activity.

Using the Correct Vocabulary to Solve Problems
Third graders examine the vocabulary and strategies to be used with addition, subtraction, and multiplication word and story problems. They observe the teacher solve a variety of problems, then write and illustrate their own original...
Curated OER
Investigating the Idea of Tan
Fifth graders use tan to solve problems involving right-angled triangles. They solve equations of the form tan(8) =a, for a between 180 degrees and 360 degrees. They state the value of tan (8) in special cases.

How Much Does a Bear Weigh?
Students estimate how many children in their class it would take to equal the mass of one adult bear. They then weigh and record their measurement on a chart to check their estimate.
Curated OER
Lesson Plan for Fontana Mines
Students estimate and compute with rational numbers. They compare, order and convert among fractions, decimals and percents. Students analyze problems to determine if there is sufficient or extraneous data to solve.
Curated OER
Data Analysis & Probability
Students make predictions based on survey results. They calcuate sample proportions. Students estimate the number of voters in their district preferring the democratic candidate using their sample results. They review sample proportions...
Curated OER
Microscopes and Crystals
Learners observe crystals under the microscope. In this science instructional activity, students compare how the crystal look like using their eyes, hand lens and microscope. They identify the type of crystal based on the amount of light...
