In this activity, learners use objects they find on a nature and water to make creative frozen sculptures.

In this activity on page 14 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners turn plain pieces of recycled plastic into shrunken works of art.

In this activity, learners discover that some plastics will shrink when you get them hot. Learners bake polystyrene in a regular oven and discover what happens.

In this activity, learners use chemistry to produce weathered "antiqued" paper with burned edges. Learners first soak white paper in coffee and then apply a charring solution of ammonium chloride.

In this activity (page 6 of the PDF), learners will observe both a chemical and a physical change.

In this activity, learners transform everyday milk into small plastic figurines and jewelry. Use this activity to introduce learners to monomers and polymers.

In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.

In this activity on page 8 of the PDF (Behind the Scenes with Chemistry), learners make three of Harry Potter's essential school supplies: quills, ink, and color-changing paper.

In this a hands-on activity, learners explore how to put ice cream in an oven without it melting. Ideas in this activity include insulation and cooking.

In this activity, learners explore the concept of density by pouring 5 different liquids into a jar. Food coloring is added if needed to give each liquid a distinct color.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

In this activity on page 4 of the PDF (Behind the Scenes with Chemistry), learners make some special effects, including snow and breaking glass, with supplies found in the home.

Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.

In this up-cycling activity, learners recycle plastic bags and repurpose them into useful wallets.

In this chemistry activity, learners witness an exothermic reaction, while making their very own, completely usable sidewalk chalk. This is also an excellent activity for exploring color mixing.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

In this activity, learners build a simple solar oven out of household materials to melt chocolate and marshmallow between graham crackers--known as s'mores.

In this activity (pages 13-14), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.

In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.

In this group activity, learners act out key stages of the "ocean carbon cycle" (also known as the "carbonate buffer system") through motions, rearranging blocks and team tasks.
