Watch two teacher critiques followed by two student critiques. Determine whether students are learning the elements of effective critique from their teachers.
Line plots are good for small amounts of data while frequency bar graphs are better for large amounts. Observe how to transition from line plot to frequency bar graph.
Measure the lengths and diagonals of three squares with a ruler. Look over your measurements and try to come up with a rule of thumb for estimating the length of a diagonal if you know the length of a side.
Imagine a cake shaped like a cube that is frosted on all six sides and will be cut into smaller cube-shaped pieces. Make predictions about the number of pieces and the amount of frosting on each piece of cake using the table to check your predictions.
Explore the effect of concave and convex mirrors. Combine concave and convex mirrors to design a fun house mirror that will create the distorted pictures of Melissa and Sam.
Explore the relationships between viruses, cells and the immune system, and the role of genes in disease resistance. See how mutations in an HIV receptor confer relative resistance to infection.
Our blood types are transmitted through multiple allelic inheritance. Identify the antigens and antibodies of the four different blood types: A, B, AB and O.
Some traits, such as colorblindness, are related to gender. Complete a Punnett square showing the possible genotypes of children born to a colorblind mother and a father with normal vision.
Test your knowledge of major events (formation of the solar system, first appearance of water, etc.) in geologic history. Afterwards put the events in the correct order on the timeline.
Learn about several three-dimensional geometric shapes and the terminology used to describe them. Learn how to calculate their surface area and volume, and explore their mathematical properties.
Test your knowledge of polyhedra, prisms, pyramids, volume, surface area, Euler’s Theorem and platonic solids. Take this 39-question test, review your correct and incorrect answers, and print out your assessment.
