Science Without a Net: Week 1

For all of the official (and free!) “Science Without A Net” lesson plans please see here.

Our Science Without A Net topic for this week is Energy. We had a lot of fun learning about the scientific definition of energy and all of its forms.

Here is the homemade book we made to help us remember what we learned about energy this week. For more on the how and why of homemade books, please see here.


This week we learned about Energy. We read Energy Makes Things Happen by Kimberly Bradley.

We made origami frogs out of paper. When the frog is just sitting there, it is full of potential energy.

When the frog is jumping, it is full of kinetic energy.

We put a ball at the top of the stairs. When the ball was at the top of the stairs it was full of potential energy.

When the ball was rolling down the stairs it was full of kinetic energy.

We built a magic can. The further away the can rolled, the more potential energy it had. The rubber band inside the can stores energy when the can rolls.

We made brownies. Stirring the brownies used kinetic energy.

Baking the brownies used heat energy.

Since they are a food, brownies are fuel for our bodies. Fuel gives us energy.

Milk is also a fuel which gives our bodies energy. The milk we drink with our brownies came from cows that ate grass. It takes solar energy from the sun to grow grass.

The last experiment we did was with sound energy. Crashing the cymbals together created sound waves. The sound waves made the salt bounce off of the plastic. Dad jumped too, because it was really loud!
