In this activity, students will learn how to read a Celsius-scale thermometer, associate weather conditions and seasons with Celsius temperature ranges, and keep a record of temperature. Students will read the Celsius temperature each day and discuss how given temperatures "feel". They record the temperature by using a string of beads and a chart. Full description.

This activity is designed to help students fully understand our planet's relationship to the Sun. Students will make predictions and measure shadows over a period of time to observe that the length of a shadow (and the angle of the Sun's rays to the Earth) changes each week. They should conclude from their data that the position of the Earth relative to the Sun changes with the seasons. Full description.

In this lesson, students will experimentally measure the strength of a magnet and graph how the strength changes as the distance from the magnet increases, and as the barrier (masking tape) is built between the magnet and an iron object. This lesson is the second in a two-lesson series on magnets. The main concept to convey in Magnets 2: How Strong is Your Magnet? is that forces can act from a distance. ... Full description.

This activity has students compare the mass of several rocks in order to find the one with the most mass. After the groups order their rocks by mass, the class reconvenes and the mass in grams is determined. Some students may notice that the biggest rock (the one with the greatest volume) is not always the most massive. This will open the door for the introduction of the concept of density.

This activity introduces students to the range of sizes among dinosaurs and other prehistoric animals, helping them to visualize the actual sizes and gain a feel for the mathematical process of scaling. This activity contains goals, materials, methods, and discussion questions. Full description.

This lesson introduces students to properties of rocks, specifically weight and density. They will select a rock, make a list of words to describe it, estimate its mass and use a balance to check their estimates, write a story about what they have learned, and group or classify the rocks according to what they have learned.
