The Age 7–9 - Semester 1 - Science Kit provides the specialized materials needed to complete hands-on investigations in units Amazing Weather, Sound, and Environments Change. These activities help children turn concepts such as air pressure, sound vibrations, and movement of Earth’s surface into observable experiences.

Engage Your Child with a Hands-on Science Curriculum

This kit uses over 50 items that are used in experiments throughout the semester. Here are a few examples your child will complete.

• Discover How Air Pressure Helps Predict Weather: Your child builds a barometer and tracks air pressure for nine days. By recording changes and making weather predictions, your child learns that rising pressure often signals clear weather, while falling pressure can signal storms.
• Explore How Vibrations Carry Sound: Your child builds a cup-and-string phone and tests how sound changes when the string is pinched. This demonstrates that sound travels through vibrations in matter.
• Investigate How Earthquakes Affect the Surface: Your child models an earthquake by moving stacked pieces of cardboard beneath small figures, cars, and houses. By comparing the effects of different movements, your child sees how shifting plates can shake Earth’s surface and affect objects above it.
• Discover How Gas Pressure Can Cause an Eruption: Your child combines baking soda and vinegar in a model volcano and observes the resulting foam. This shows how expanding gas can build pressure and push material outward.

A Complete Hands-On Science Experience

Hands-on science often requires families to gather supplies for individual investigations. This kit provides specialized materials for the featured activities, simplifying preparation so parents can focus more attention on guiding observations, questions, and discussion.
