In this activity learners will measure and manipulate flubber using different tools. Learners will explore volume and make observations about texture and shapes.

In this math lesson, learners participate in several activities where they apply measurement skills.

In this math lesson, learners rotate through various centers while comparing and ordering objects according to length.

In this nutrition and estimation activity (page 12 of PDF), learners estimate serving sizes of different foods and compare their estimates to serving size information provided on nutrition food labels

This activity (on page 2 of the PDF under SciGirls Activity: Water Slides) is a full inquiry investigation into speed and motion and takes place at a water park.

In this activity, learners count and measure kidney beans to explore natural selection and variation. Learners measure the length of 50-100 beans.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

In this activity, learners build their own magnetometer using an empty soda bottle, magnets, laser pointer, and household objects.

In this activity, learners mimic remote sensing. Learners use a stick to measure the distance to a "planet surface" they cannot see, and create their own map of the landscape.

This activity was designed for blind learners, but all types of learners can use it to learn to differentiate between qualitative and quantitative observations and to practice data collection.

In this activity, learners model the gravitational fields of planets on a flexible surface.

This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

In this math lesson, learners use a variety of manipulatives to explore spatial relationships of squares and their transformations.

In this experiment, learners will conduct chemical and physical tests to identify mystery substances.

Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

In this activity, learners discuss the different salinities of oceans, rivers and estuaries.
