In this activity, learners will explore engineering concepts to construct a blanket fort using materials sourced from home.

Learners work in groups to build model cars from paper parts. First, each learner builds cars individually and the group times themselves.

In this activity, learners will explore light with reflective surfaces. Learners will make predictions and share their observations as they experiment with directing a beam of light.

In this simulation activity, learners observe what can happen when ocean waves churn up water and oil from an oil spill.

In this activity (page 105 of the PDF), learners measure heart rate and blood pressure and learn how to obtain consistent measurements during repeated tests.

Learners cut out pictures of continents and attempt to put them together to form Pangaea, the supercontinent present on the Earth approximately 300 million years ago.

In this activity, learners mix ingredients in a plastic bag, and then identify three characteristics of a chemical reaction: production of heat, color change, and production of a gas.

In this three-part activity, learners play a game and conduct two simple experiments to explore water and surface tension. Learners will have fun discovering how water "sticks" together.

In this activity, learners use found natural materials to create a water haven for bees and other insects.

This activity (aka "snack") provides instructions for discovering your blind spot. It is an exploration of light and visual perception using simple materials you may have around the house.

In this activity, learners create a kind of balance device using a wire coat hanger, some string, and paper cups.

In this activity, learners explore color, light and shadow by creating their own puppets to hold in front of a light source.

This simple but open-ended math game introduces basic probability concepts using coins and dice. Players roll the dice and collect coins to match the number rolled.

In this chemistry activity (page 6 of the PDF), learners observe a chemical change. Learners write and reveal a secret message using edible ink.

Learners examine the properties of light by experimenting with an LED-flashlight and polarizing filters. When two polarizers are used, they block all light when they are placed at right angles.

In this math activity, learners guess a secret number between 1 and 100 in a three-player game.

This lesson (on pages 15-24 of PDF) explores how sound is caused by vibrating objects. It explains that we hear by feeling vibrations passing through the air.

In this activity, challenge learners to predict and investigate how many water drops they can fit on one penny.

In this math activity, learners create a magic turtle where all the rows, columns and diagonals add up to fifteen.

In this activity, learners are introduced to division and fractions as they share snacks with a group of friends.
