This is an activity about visual analysis. Learners will compare and contrast images of Earth and Mars and then experiment with lenses to understand more about the instruments used to make the pictures. This is activity 1 of 9 in Mars and Earth:... (View More)

Learners will use trays of sand and cups of water to recreate surface features seen in images of Mars. This is activity 5 of 9 in Mars and Earth: Science Learning Activities for After School.

Keywords: Mars

This activity introduces the importance of meteorites to the understanding of the origin of the Solar System. Learners will use a key to determine if samples are meteorites. Finding meteorites can be difficult because most meteorites look like Earth... (View More)

In this activity, students experiment to test the hypothesis that Mars was once hotter. The activity requires some advance preparation by the teacher: the day before the activity, need to place a plastic bottle filled with water in the freezer.... (View More)

In this activity students convert antilogs to logs, and logs to antilogs using scientific notation as an intermediate step. They will thereby develop a look-up table for solving math problems by using logarithms. This is activity D2 in the "Far Out... (View More)

In this activity students construct multiplying slide rules scaled in Base-10 exponents and use them to calculate products and quotients. They will come to appreciate that super numbers (exponents, orders of magnitude and logarithms) play by... (View More)

In this activity students add and subtract log distances on their Log Tapes to discover that the corresponding numbers multiply and divide. This will lead them to an experiential understanding of the laws of logarithms. This is activity B2 in the... (View More)

In this activity students use their Log Tapes as a reference for ordered pairs, and graph positive numbers as a function of their base-10 logarithms. They extend each plotted point to the vertical axis, thereby generating a logarithmic scale that... (View More)

In this activity students construct Log Rulers, finely calibrated in base-10 exponents and numbers (logs and antilogs). They practice reading these scales as accurately as possible, listing all certain figures plus one uncertain figure.  This is... (View More)

In this activity students construct Log Tapes calibrated in base-ten exponents, then use them to derive relationships between base-ten logs (exponents) and antilogs (ordinary numbers).  This is activity B1 in the "Far Out Math" educator's guide.... (View More)
