In this outdoor activity, learners investigate spider webs and feeding behavior, particularly how spiders trap food in their sticky silk webs while not getting stuck themselves.

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.

Learners design their own experiment to determine which M&M color dissolves the fastest in water.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

This activity uses turmeric, a common spice in curry, as an indicator for acidity and basicity. Turmeric is yellow in acid and neutral substances, but turns bright red with bases.

Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.

In this activity, learners investigate the process of osmosis by adding salt to a sealed bag of raw carrots and comparing it to a control.

This laboratory exercise is designed to show learners how DNA can be extracted from a chunk of thymus (sweetbread) or liver.

Create a chemical reaction that makes cheese! This hands-on activity demonstrates that molecules and atoms are tiny particles that make up everything around us.

In this design challenge, learners use their creativity and imagination to design and test a wildlife crossing for their favorite animal.

This is an activity (on page 2 of the PDF under Surface Area Activity) about surface area to volume ratio.

In this activity, learners compare and contrast their own skin (including the area covered) with that of an orange.

In this activity, learners test the pH of safe liquids available at home by creating a pH indicator from mashed blueberries.

In this activity, learners are challenged to design and build the tools they need to survive being shipwrecked on a deserted island.

Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.

In this activity, learners build models of atoms and molecules, then consider their role in different phases of matter, density, and mixtures and solutions.

In this activity related to the human circulatory system (on page 10 of the PDF), learners observe the dispersion of a drop of food coloring in water, draw conclusions about the movement of dissolved

In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.
