Test Your Dominant Side

You probably know if you are right or left-handed, but do you know what your dominant foot is, or even which eye is more dominant when you look at things? Your dominant side may vary depending on which side of your brain controls language or even because of the culture you are raised in. Go through a series of challenges and record what side you use for each task! You might even be ambidextrous!

After School Week 8

Engineering the Earth: Exploring Hydroelectric Energy

Let’s create energy with renewable resources! This week the girls created water wheels just like Water Resource Engineers to see how hydroelectric power is created. The students used a foil circle and cut wedges into 4 or 8 blades then stuck a pencil through the middle. They placed it under running water and analyzed the hydropower in trials.

After School 'To Go' Week 7

Biomass: Biofuels

Now that the girls are aware that nonrenewable resources cannot be used again, their task was to come up with an alternative resource for energy. Biofuel engineers figure out ways to use animal and plant wastes as fuels. Students mixed warm water, yeast, and sugar in a bottled water as they watched the balloon expand.

Steel Wool & Vinegar Reaction

Want to see a chemical reaction release energy in the form of heat? Soak some steel wool in vinegar for a minute and then place it in another beaker. Monitor the initial temperature and compare it to the temperature after 5 minutes in the covered container. The beaker might even begin to get foggy as the temperature increases!
